In some cases -- see below -- PortMidi does - not buffer output at all and merely passes data to a lower-level - API, in which case \p bufferSize is ignored. Since MIDI speeds now - vary from 1 to 50 or more messages per ms (over USB), put some - thought into this number. E.g. if latency is 20ms and you want to - burst 100 messages in that time (5000 messages per second), you - should set \p bufferSize to at least 100. The default on Windows - assumes an average rate of 500 messages per second and in this - example, output would be slowed waiting for free buffers. - - @param latency the delay in milliseconds applied to timestamps - to determine when the output should actually occur. (If latency is - < 0, 0 is assumed.) If latency is zero, timestamps are ignored - and all output is delivered immediately. If latency is greater - than zero, output is delayed until the message timestamp plus the - latency. (NOTE: the time is measured relative to the time source - indicated by time_proc. Timestamps are absolute, not relative - delays or offsets.) In some cases, PortMidi can obtain better - timing than your application by passing timestamps along to the - device driver or hardware, so the best strategy to minimize jitter - is: wait until the real time to send the message, compute the - message, attach the *ideal* output time (not the current real - time, because some time may have elapsed), and send the - message. The \p latency will be added to the timestamp, and - provided the elapsed computation time has not exceeded \p latency, - the message will be delivered according to the timestamp. If the - real time is already past the timestamp, the message will be - delivered as soon as possible. Latency may also help you to - synchronize MIDI data to audio data by matching \p latency to the - audio buffer latency. - - @param time_proc (address of) a pointer to a procedure that - returns time in milliseconds. It may be NULL, in which case a - default millisecond timebase (PortTime) is used. If the - application wants to use PortTime, it should start the timer (call - Pt_Start) before calling #Pm_OpenInput or #Pm_OpenOutput. If the - application tries to start the timer *after* #Pm_OpenInput or - #Pm_OpenOutput, it may get a #ptAlreadyStarted error from #Pt_Start, - and the application's preferred time resolution and callback - function will be ignored. \p time_proc times are used to schedule - outgoing MIDI data (when latency is non-zero), usually by mapping - from time_proc timestamps to internal system timestamps to - maintain the precision of system-supported timing. - - @param time_info a pointer passed to time_proc. - - @return #pmNoError and places a pointer to a valid #PortMidiStream - in the stream argument. If the operation fails, a nonzero error - code is returned (see PMError) and the value of \p stream is - invalid. - - Note: ALSA appears to have a fixed-size priority queue for timed - output messages. Testing indicates the queue can hold a little - over 400 3-byte MIDI messages. Thus, you can send 10,000 - messages/second if the latency is 30ms (30ms * 10000 msgs/sec * - 0.001 sec/ms = 300 msgs), but not if the latency is 50ms - (resulting in about 500 pending messages, which is greater than - the 400 message limit). Since timestamps in ALSA are relative, - they are of less value than absolute timestamps in macOS and - Windows. This is a limitation of ALSA and apparently a design - flaw. - - Example 1: If I provide a timestamp of 5000, latency is 1, and - time_proc returns 4990, then the desired output time will be when - time_proc returns timestamp+latency = 5001. This will be 5001-4990 - = 11ms from now. - - Example 2: If I want to send at exactly 5010, and latency is 10, I - should wait until 5000, compute the messages and provide a - timestamp of 5000. As long as computation takes less than 10ms, - the message will be delivered at time 5010. - - Example 3 (recommended): It is often convenient to ignore latency. - E.g. if a sequence says to output at time 5010, just wait until - 5010, compute the message and use 5010 for the timestamp. Delivery - will then be at 5010+latency, but unless you are synchronizing to - something else, the absolute delay by latency will not matter. - - Any stream that is successfully opened should eventually be closed - by calling Pm_Close(). -*/ -PMEXPORT PmError Pm_OpenOutput(PortMidiStream** stream, - PmDeviceID outputDevice, - void *outputSysDepInfo, - int32_t bufferSize, - PmTimeProcPtr time_proc, - void *time_info, - int32_t latency); - -/** Create a virtual input device. - - @param name gives the virtual device name, which is visible to - other applications. - - @param interf is the interface (System API) used to create the - device Default interfaces are "MMSystem", "CoreMIDI" and - "ALSA".

MIDI real-time messages are one-byte - messages used mainly for timing (see the MIDI spec). PortMidi retains - the order of non-real-time MIDI messages on both input and output, but - it does not specify exactly how real-time messages are processed. This - is particulary problematic for MIDI input, because the input parser - must either prepare to buffer an unlimited number of sysex message - bytes or to buffer an unlimited number of real-time messages that - arrive embedded in a long sysex message. To simplify things, the input - parser is allowed to pass real-time MIDI messages embedded within a - sysex message, and it is up to the client to detect, process, and - remove these messages as they arrive. - - When receiving sysex messages, the sysex message is terminated - by either an EOX status byte (anywhere in the 4 byte messages) or - by a non-real-time status byte in the low order byte of the message. - If you get a non-real-time status byte but there was no EOX byte, it - means the sysex message was somehow truncated. This is not - considered an error; e.g., a missing EOX can result from the user - disconnecting a MIDI cable during sysex transmission. - - A real-time message can occur within a sysex message. A real-time - message will always occupy a full PmEvent with the status byte in - the low-order byte of the PmEvent message field. (This implies that - the byte-order of sysex bytes and real-time message bytes may not - be preserved -- for example, if a real-time message arrives after - 3 bytes of a sysex message, the real-time message will be delivered - first. The first word of the sysex message will be delivered only - after the 4th byte arrives, filling the 4-byte PmEvent message field. - - The timestamp field is observed when the output port is opened with - a non-zero latency. A timestamp of zero means "use the current time", - which in turn means to deliver the message with a delay of - latency (the latency parameter used when opening the output port.) - Do not expect PortMidi to sort data according to timestamps -- - messages should be sent in the correct order, and timestamps MUST - be non-decreasing. See also "Example" for Pm_OpenOutput() above. - - A sysex message will generally fill many #PmEvent structures. On - output to a #PortMidiStream with non-zero latency, the first timestamp - on sysex message data will determine the time to begin sending the - message. PortMidi implementations may ignore timestamps for the - remainder of the sysex message. - - On input, the timestamp ideally denotes the arrival time of the - status byte of the message. The first timestamp on sysex message - data will be valid. Subsequent timestamps may denote - when message bytes were actually received, or they may be simply - copies of the first timestamp. - - Timestamps for nested messages: If a real-time message arrives in - the middle of some other message, it is enqueued immediately with - the timestamp corresponding to its arrival time. The interrupted - non-real-time message or 4-byte packet of sysex data will be enqueued - later.

----------- some notes on the design of PortMidi ----------
-
-POINTERS VS DEVICE NUMBERS
-
-When you open a MIDI port, PortMidi allocates a structure to
-maintain the state of the open device. Since every device is
-also listed in a table, you might think it would be simpler to
-use the table index rather than a pointer to identify a device.
-This would also help with error checking (it's hard to make
-sure a pointer is valid). PortMidi's design parallels that of
-PortAudio.
-
-ERROR HANDLING
-
-Error handling turned out to be much more complicated than expected.
-PortMidi functions return error codes that the caller can check.
-In addition, errors may occur asynchronously due to MIDI input.
-However, for Windows, there are virtually no errors that can
-occur if the code is correct and not passing bogus values. One
-exception is an error that the system is out of memory, but my
-guess is that one is unlikely to recover gracefully from that.
-Therefore, all errors in callbacks are guarded by assert(), which
-means not guarded at all in release configurations.
-
-Ordinarily, the caller checks for an error code. If the error is
-system-dependent, pmHostError is returned and the caller can
-call Pm_GetHostErrorText to get a text description of the error.
-
-Host error codes are system-specific and are recorded in the
-system-specific data allocated for each open MIDI port.
-However, if an error occurs on open or close,
-we cannot store the error with the device because there will be
-no device data (assuming PortMidi cleans up after devices that
-are not open). For open and close, we will convert the error
-to text, copy it to a global string, and set pm_hosterror, a
-global flag.
-
-Similarly, whenever a Read or Write operation returns pmHostError,
-the corresponding error string is copied to a global string
-and pm_hosterror is set. This makes getting error strings
-simple and uniform, although it does cost a string copy and some
-overhead even if the user does not want to look at the error data.
-
-The system-specific Read, Write, Poll, etc. implementations should
-check for asynchronous errors and return immediately if one is
-found so that these get reported. This happens in the Mac OS X
-code, where lots of things are happening in callbacks, but again,
-in Windows, there are no error codes recorded in callbacks.
-
-DEBUGGING
-
-If you are building a console application for research, we suggest
-compiling with the option PM_CHECK_ERRORS. This will insert a
-check for error return values at the end of each PortMidi
-function. If an error is encountered, a text message is printed
-using printf(), the user is asked to type ENTER, and then exit(-1)
-is called to clean up and terminate the program.
-
-You should not use PM_CHECK_ERRORS if printf() does not work
-(e.g. this is not a console application under Windows, or there
-is no visible console on some other OS), and you should not use
-PM_CHECK_ERRORS if you intend to recover from errors rather than
-abruptly terminate the program.
-
-The Windows version (and perhaps others) also offers a DEBUG
-compile-time option. See README_WIN.txt.
-
-RELEASE
-
-To make a new release, update VERSION variable in CMakeLists.txt.
-
-Update CHANGELOG.txt. What's new?

-
- This queue implementation uses the "light pipe" algorithm which
- operates correctly even with multi-processors and out-of-order
- memory writes. (see Alexander Dokumentov, "Lock-free Interprocess
- Communication," Dr. Dobbs Portal, http://www.ddj.com/,
- articleID=189401457, June 15, 2006. This algorithm requires that
- messages be translated to a form where no words contain
- zeros. Each word becomes its own "data valid" tag. Because of this
- translation, we cannot return a pointer to data still in the queue
- when the "peek" method is called. Instead, a buffer is
- preallocated so that data can be copied there. Pm_QueuePeek()
- dequeues a message into this buffer and returns a pointer to it. A
- subsequent Pm_Dequeue() will copy from this buffer.
-
- This implementation does not try to keep reader/writer data in
- separate cache lines or prevent thrashing on cache lines.
- However, this algorithm differs by doing inserts/removals in
- units of messages rather than units of machine words. Some
- performance improvement might be obtained by not clearing data
- immediately after a read, but instead by waiting for the end
- of the cache line, especially if messages are smaller than
- cache lines. See the Dokumentov article for explanation.
-
- The algorithm is extended to handle "overflow" reporting. To
- report an overflow, the sender writes the current tail position to
- a field. The receiver must acknowlege receipt by zeroing the
- field. The sender will not send more until the field is zeroed.

This means that PortMidi has retained a more specific - * system-dependent error code. The caller can get more information - * by calling Pm_GetHostErrorText() to get a text string describing - * the error. Host errors can arise asynchronously from callbacks, - * * so there is no specific return code. Asynchronous errors are - * checked and reported by Pm_Poll. You can also check by calling - * Pm_HasHostError(). If this returns TRUE, Pm_GetHostErrorText() - * will return a text description of the error. - * - * NOTES ON COMPILE-TIME SWITCHES - * - * DEBUG assumes stdio and a console. Use this if you want - * automatic, simple error reporting, e.g. for prototyping. If - * you are using MFC or some other graphical interface with no - * console, DEBUG probably should be undefined. - * PM_CHECK_ERRORS more-or-less takes over error checking for - * return values, stopping your program and printing error - * messages when an error occurs. This also uses stdio for - * console text I/O.

MIDI real-time messages are one-byte - messages used mainly for timing (see the MIDI spec). PortMidi retains - the order of non-real-time MIDI messages on both input and output, but - it does not specify exactly how real-time messages are processed. This - is particulary problematic for MIDI input, because the input parser - must either prepare to buffer an unlimited number of sysex message - bytes or to buffer an unlimited number of real-time messages that - arrive embedded in a long sysex message. To simplify things, the input - parser is allowed to pass real-time MIDI messages embedded within a - sysex message, and it is up to the client to detect, process, and - remove these messages as they arrive. - - When receiving sysex messages, the sysex message is terminated - by either an EOX status byte (anywhere in the 4 byte messages) or - by a non-real-time status byte in the low order byte of the message. - If you get a non-real-time status byte but there was no EOX byte, it - means the sysex message was somehow truncated.

-This directory implements a JNI library so that Java programs can use
-the PortMidi API. This was mainly created to implement PmDefaults, a
-program to set default input and output devices for PortMidi
-applications. Because it is rarely used, PmDefaults was dropped from
-PortMidi starting with v3. I recommend you implement per-application
-preferences and store default PortMidi device numbers for input and
-output there. (Or better yet, store device *names* since numbers can
-change if you plug in or remove USB devices.)
-
-Even without PmDefaults, a PortMidi API for Java is probably an
-improvement over other Java libraries, but there is very little MIDI
-development in Java, so I have not maintained this API. The only thing
-probably seriously wrong now is an interface to the
-Pm_CreateVirtualInput and Pm_CreateVirtualOutput functions, which are
-new additions.
-
-I will leave the code here, and if there is a demand, please either
-update it or let your needs be known. Perhaps I or someone can help.
-
-==================================================================
-
-BUILDING Java EXTERNAL LIBRARY
-
-You must have a JDK installed (Java development kit including javac
-(the Java compiler), jni.h, etc.
-
-Test java on the command line, e.g., type: javac -version
-
-Enable these options in the main CMakeLists.txt file (run CMake
-from your top-level repository directory):
- BUILD_JAVA_NATIVE_INTERFACE
-In my Ubuntu linux with jdk-15, ccmake was unable to find my JDK, so
-I have to manually set CMake variables as follows (type 't' to see
-these in ccmake):
- JAVA_AWT_INCLUDE_PATH /usr/lib/jvm/jdk-15/include
- JAVA_AWT_LIBRARY /usr/lib/jvm/jdk-15/lib
- JAVA_INCLUDE_PATH /usr/lib/jvm/jdk-15/include
- JAVA_INCLUDE_PATH2 /usr/lib/jvm/jdk-15/include
- JAVA_JVM_LIBRARY /usr/lib/jvm/jdk-15/lib
-Of course, your paths may differ.

-
-revised Mar 2024 to remove pmdefaults references
-revised Jan 2022 for the PortMidi/portmidi repo on github.com
-revised 20 Sep 2010 for Xcode 4.3.2 and CMake 2.8.8
-
-This documents how I build PortMidi for macOS. It's not the only way,
-and command-line/scripting enthusiasts will say it's not even a good
-way. Feel free to contribute your approach if you are willing to
-describe it carefully and test it.
-
-Install Xcode and the CMake application, CMake.app. I use the GUI
-version of CMake which makes it easy to see/edit variables and
-options.
-
-==== USING CMAKE ====
-
-Run CMake.app and select your portmidi repo working directory as the
-location for source and build. (Yes, I use so called "in-tree"
-builds -- it doesn't hurt, but I don't think it is necessary.)
-
-Default settings should all be fine, but select options under BUILD if
-you wish:
-
-BUILD_NATIVE_JAVA_INTERFACE to build a Java interface (JNI) library.
-
-BUILD_PORTMIDI_TESTS to create some test programs. Of particular
-interest are test/mm, a handy command-line MIDI Input Monitor, and
-test/testio, a simple command-line program to send or receive some
-MIDI notes in case you need a quick test: What devices do I have? Does
-this input work? Does this output work?
-
-I disable BUILD_SHARED_LIBS and always link statically: Static linking only
-adds about 40KB to any application and then you don't have to worry
-about versions, instally, copying or finding the dynamic link library,
-etc.
-
-To make sure you link statically, I rename the library to
-libportmidi_static.a. To do this, set PM_STATIC_LIB_NAME (in CMake,
-under the "PM" group) to "portmidi_static", and of course your
-application will have to specify portmidi_static as the library to
-link to.
-
-If you are building simple command-line applications, you might want
-to enable PM_CHECK_ERRORS. If you do, then calls into the PortMidi
-library will print error messages and exit in the event of an error
-(such as trying to open a device that does not exist). This saves you
-from having to check for errors everytime you call a library function
-or getting confused when errors are detected but not reported. For
-high-quality applications, do NOT enable PM_CHECK_ERRORS -- any
-failure could immediately abort your whole application, which is not
-very friendly to users.
-
-Click on Configure (maybe a couple of times).
-
-Click on Generate and make an Xcode project.
-
-Open portmidi/portmidi.xcodeproj with Xcode and build what you
-need. The simplest thing is to build the ALL_BUILD target. Be careful
-to specify a Debug or Release depending on what you want. "ALL_BUILD"
-is a misnomer -- it only builds the version you select.

But - CoreMIDI does not have a way to shut down(!), and even - MIDIClientDispose() somehow retains state (and docs say do not - call it even if it worked). The solution, apparently, is to - call CFRunLoopRunInMode(), which somehow updates CoreMIDI - state. - - But when do we call CFRunLoopRunInMode()? I tried calling it - in midi_in_poll() which is called when you call Pm_Read() since - that is called often. I observed that this caused the program - to block for as long as 50ms and fairly often for 2 or 3ms. - What was Apple thinking? Is it really OK to design systems that - can only function with a tricky multi-threaded, non-blocking - priority-based solution, and then not provide a proof of concept - or documentation? Or is Apple's design really flawed? If anyone - at Apple reads this, please let me know -- I'm curious. - - But I digress... Here's the PortMidi approach: Since - CFRunLoopRunInMode() is potentially a non-realtime operation, - we only call it in Pm_Initialize(), where other calls to look - up devices and device names are quite slow to begin with. Again, - PortMidi does not actively scan for new or deleted devices, so - if devices change, you won't see it until the next Pm_Terminate - and Pm_Initialize. - - Calling CFRunLoopRunInMode() once is probably not enough. There - might be better way, but it seems to work to just call it 100 - times and insert 20 1ms delays (in case some inter-process - communication or synchronization is going on). - This adds 20ms to the wall time of Pm_Initialize(), but it - typically runs 30ms to much more (~4s), so this has little impact. - */ - -#include <stdlib.h> - -/* turn on lots of debugging print statements */ -#define CM_DEBUG if (0) -/* #define CM_DEBUG if (1) */ - -#include "portmidi.h" -#include "pmutil.h" -#include "pminternal.h" -#include "porttime.h" -#include "pmmacosxcm.h" - -#include <stdio.h> -#include <string.h> - -#include <CoreServices/CoreServices.h> -#include <CoreMIDI/MIDIServices.h> -#include <CoreAudio/HostTime.h> -#include <unistd.h> -#include <libkern/OSAtomic.h> - -#define PACKET_BUFFER_SIZE 1024 -/* maximum overall data rate (OS X limits MIDI rate in case there - * is a cycle among IAC ports. - */ - -#define MAX_BYTES_PER_S 5400 - -/* Apple reports that packets are dropped when the MIDI bytes/sec - exceeds 15000.

(I measured 0.5 Mbps each way over USB to a - Teensy 3.2 microcontroller implementing a USB MIDI loopback. Maybe - it would get 1 Mbps one-way, which would make the CoreMIDI - restriction 18x slower than USB. Maybe other USB MIDI - implementations are faster -- USB top speed for other protocols is - certainly higher than 1 Mbps!) - - This is apparently based on timestamps, not on real time, so we - have to avoid constructing packets that schedule high speed output - regardless of when writes occur. The solution is to alter - timestamps to limit data rates. This adds a slight time - distortion, e.g. an 11 note chord with all notes on the same - timestamp will be altered so that the last message is delayed by - 11 messages x 3 bytes/message / 5400 bytes/second = 6.1 ms. - Note that this is about 2x MIDI speed, but at least 18x slower - than USB MIDI. - - Altering timestamps creates another problem, which is that a sender - that exceeds the maximum rate can queue up an unbounded number of - messages. With non-USB MIDI devices, you could be writing 5x faster - to CoreMIDI than the hardware interface can send, causing an - unbounded backlog, not to mention that the output stream will be a - steady byte stream (e.g., one 3-byte MIDI message every 0.55 ms), - losing any original timing or rhythm. PortMidi does not guarantee - delivery if, over the long run, you write faster than the hardware - can send. - - The LIMIT_RATE symbol, if defined (which is the default), enables - code to modify timestamps for output to an IAC device as follows: - - Before a packet is formed, the message timestamp is set to the - maximum of the PortMidi timestamp (converted to CoreMIDI time) - and min_next_time. After each send, min_next_time is updated to - the packet time + packet length * delay_per_byte, which limits - the scheduled bytes-per-second. Also, after each packet list - flush, min_next_time is updated to the maximum of min_next_time - and the real time, which prevents many bytes to be scheduled in - the past. (We could more directly just say packets are never - scheduled in the past, but we prefer to get the current time -- a - system call -- only when we perform the more expensive operation - of flushing packets, so that's when we update min_next_time to - the current real time. If we are sending a lot, we have to flush - a lot, so the time will be updated frequently when it matters.) - - This possible adjustment to timestamps can distort accurate - timestamps by up to 0.556 us per 3-byte MIDI message. - - Nothing blocks the sender from queueing up an arbitrary number of - messages.

-/* Latency is defined here to mean the time starting when a
- process becomes ready to run, and ending when the process
- actually runs. Latency is due to contention for the
- processor, usually due to other processes, OS activity
- including device drivers handling interrupts, and
- waiting for the scheduler to suspend the currently running
- process and activate the one that is waiting.
-
- Latency can affect PortMidi applications: if a process fails
- to wake up promptly, MIDI input may sit in the input buffer
- waiting to be handled, and MIDI output may not be generated
- with accurate timing. Using the latency parameter when
- opening a MIDI output port allows the caller to defer timing
- to PortMidi, which in most implementations will pass the
- data on to the OS. By passing timestamps and data to the
- OS kernel, device driver, or even hardware, there are fewer
- sources of latency that can affect the ultimate timing of
- the data. On the other hand, the application must generate
- and deliver the data ahead of the timestamp. The amount by
- which data is computed early must be at least as large as
- the worst-case latency to avoid timing problems.
-
- Latency is even more important in audio applications. If an
- application lets an audio output buffer underflow, an audible
- pop or click is produced. Audio input buffers can overflow,
- causing data to be lost. In general the audio buffers must
- be large enough to buffer the worst-case latency that the
- application will encounter.
-
- This program measures latency by recording the difference
- between the scheduled callback time and the current real time.
- We do not really know the scheduled callback time, so we will
- record the differences between the real time of each callback
- and the real time of the previous callback. Differences that
- are larger than the scheduled difference are recorded. Smaller
- differences indicate the system is recovering from an earlier
- latency, so these are ignored.
- Since printing by the callback process can cause all sorts of
- delays, this program records latency observations in a
- histogram. When the program is stopped, the histogram is
- printed to the console.
-
- Optionally the system can be tested under a load of MIDI input,
- MIDI output, or both. If MIDI input is selected, the callback
- thread will read any waiting MIDI events each iteration. You
- must generate events on this interface for the test to actually
- put any appreciable load on PortMidi. If MIDI output is
- selected, alternating note on and note off events are sent each
- X iterations, where you specify X. For example, with a timer
- callback period of 2ms and X=1, a MIDI event is sent every 2ms.
-
-
- INTERPRETING RESULTS: Time is quantized to 1ms, so there is
- some uncertainty due to rounding. A microsecond latency that
- spans the time when the clock is incremented will be reported
- as a latency of 1. On the other hand, a latency of almost
- 1ms that falls between two clock ticks will be reported as
- zero. In general, if the highest nonzero bin is numbered N,
- then the maximum latency is N+1.

-/* suppose you want low-latency midi-thru processing, but your

-
- This program illustrates how to use a timer callback from PortTime
- to implement a low-latency process that handles midi thru,
- including correctly merging midi data from the application with
- midi data from the input port.
-
- The main application, which runs in the main program thread, will
- use an interface similar to that of PortMidi, but since PortMidi
- does not allow concurrent threads to share access to a stream, the
- application will call private methods that transfer MIDI messages
- to and from the timer thread using lock-free queues. All PortMidi
- API calls are made from the timer thread.
- */
-
-/* DESIGN
-
-All setup will be done by the main thread. Then, all direct access to
-PortMidi will be handed off to the timer callback thread.
-
-After this hand-off, the main thread will get/send messages via a queue.
-
-The goal is to send incoming messages to the midi output while merging
-any midi data generated by the application. Sysex is a problem here
-because you cannot insert (merge) a midi message while a sysex is in
-progress. There are at least three ways to implement midi thru with
-sysex messages:
-
-1) Turn them off. If your application does not need them, turn them off
- with Pm_SetFilter(midi_in, PM_FILT_ACTIVE | PM_FILT_SYSEX). You will
- not receive sysex (or active sensing messages), so you will not have
- to handle them.
-
-2) Make them atomic. As you receive sysex messages, copy the data into
- a (big) buffer. Ideally, expand the buffer as needed -- sysex messages
- do not have any maximum length. Even more ideally, use a list structure
- and real-time memory allocation to avoid latency in the timer thread.
- When a full sysex message is received, send it to the midi output all
- at once.
-
-3) Process sysex incrementally. Send sysex data to midi output as it
- arrives. Block any non-real-time messages from the application until
- the sysex message completes. There is the risk that an incomplete
- sysex message will block messages forever, so implement a 5-second
- timeout: if no sysex data is seen for 5 seconds, release the block,
- possibly losing the rest of the sysex message.
-
- Application messages must be processed similarly: once started, a
- sysex message will block MIDI THRU processing. We will assume that
- the application will not abort a sysex message, so timeouts are not
- necessary here.
-
-This code implements (3).
-
-Latency is also an issue. PortMidi requires timestamps to be in
-non-decreasing order. Since we'll be operating with a low-latency
-timer thread, we can just set the latency to zero meaning timestamps
-are ignored by PortMidi. This will allow thru to go through with
-minimal latency. The application, however, needs to use timestamps
-because we assume it is high latency (the whole purpose of this
-example is to illustrate how to get low-latency thru with a high-latency
-application.) So the callback thread will implement midi timing by
-observing timestamps. The current timestamp will be available in the
-global variable current_timestamp.

- Using Portmidi
- To Install Portmidi
- To Compile Portmidi
- About Cmake
- Using other versions of Visual C++
- To Create Your Own Portmidi Client Application
-
-
-
-=============================================================================
-USING PORTMIDI:
-=============================================================================
-
-I recommend building a static library and linking with your
-application. PortMidi is not large. See ../README.md for
-basic compiling instructions.
-
-The Windows version has a couple of extra switches: You can define
-DEBUG and MMDEBUG for a few extra messages (see the code).
-
-If PM_CHECK_ERRORS is defined, PortMidi reports and exits on any
-error. This requires terminal output to see, and aborts your
-application, so it's only intended for quick command line programs
-where you do not care to check return values and handle errors
-more robustly.
-
-PortMidi is designed to run without a console and should work perfectly
-well within a graphical user interface application.
-
-Read the portmidi.h file for PortMidi API details on using the PortMidi API.
-See <...>\pm_test\testio.c and other files in pm_test for usage examples.
-
-There are many other programs in pm_test, including a MIDI monitor.
-
-
-============================================================================
-DESIGN NOTES
-============================================================================
-
-Orderly cleanup after errors are encountered is based on a fixed order of
-steps and state changes to reflect each step. Here's the order:
-
-To open input:
- initialize return value to NULL
- - allocate the PmInternal strucure (representation of PortMidiStream)
- return value is (non-null) PmInternal structure
- - allocate midi buffer
- set buffer field of PmInternal structure
- - call system-dependent open code
- - allocate midiwinmm_type for winmm dependent data
- set descriptor field of PmInternal structure
- - open device
- set handle field of midiwinmm_type structure
- - allocate buffers
- - start device
- - return
- - return
-
-SYSEX HANDLING
-
-There are three cases: simple output, stream output, input
-Each must deal with:
- 1. Buffer Initialization (creating buffers)
- 2. Buffer Allocation (finding a free buffer)
- 3. Buffer Fill (putting bytes in the buffer)
- 4. Buffer Preparation (midiOutPrepare, etc.)
- 5. Buffer Send (to Midi device)
- 6. Buffer Receive (in callback)
- 7. Buffer Empty (removing bytes from buffer)
- 8. Buffer Free (returning to the buffer pool)
- 9. Buffer Finalization (returning to heap)
-
-Here's how simple output handles sysex:
- 1. Buffer Initialization (creating buffers)
- allocated when code tries to write first byte to a buffer
- the test is "if (!m->sysex_buffers[0]) { ... }"
- this field is initialized to NULL when device is opened
- the size is SYSEX_BYTES_PER_BUFFER
- allocate_sysex_buffers() does the initialization
- note that the actual size of the allocation includes
- additional space for a MIDIEVENT (3 longs) which are
- not used in this case
- 2. Buffer Allocation (finding a free buffer)
- see get_free_sysex_buffer()
- cycle through m->sysex_buffers[] using m->next_sysex_buffer
- to determine where to look next
- if nothing is found, wait by blocking on m->sysex_buffer_signal
- this is signaled by the callback every time a message is
- received
- 3. Buffer Fill (putting bytes in the buffer)
- essentially a state machine approach
- hdr->dwBytesRecorded is a position in message pointed to by m->hdr
- keep appending bytes until dwBytesRecorded >= SYSEX_BYTES_PER_BUFFER
- then send the message, reseting the state to initial values
- 4. Buffer Preparation (midiOutPrepare, etc.)
- just before sending in winmm_end_sysex()
- 5. Buffer Send (to Midi device)
- message is padded with zero at end (since extra space was allocated
- this is ok) -- the zero works around a bug in (an old version of)
- MIDI YOKE drivers
- dwBufferLength gets dwBytesRecorded, and dwBytesRecorded gets 0
- uses midiOutLongMsg()
- 6. Buffer Receive (in callback)
- 7. Buffer Empty (removing bytes from buffer)
- not applicable for output
- 8. Buffer Free (returning to the buffer pool)
- unprepare message to indicate that it is free
- SetEvent on m->buffer_signal in case client is waiting
- 9. Buffer Finalization (returning to heap)
- when device is closed, winmm_out_delete frees all sysex buffers
-
-Here's how stream output handles sysex:
- 1. Buffer Initialization (creating buffers)
- same code as simple output (see above)
- 2. Buffer Allocation (finding a free buffer)
- same code as simple output (see above)
- 3. Buffer Fill (putting bytes in the buffer)
- essentially a state machine approach
- m->dwBytesRecorded is a position in message
- keep appending bytes until buffer is full (one byte to spare)
- 4. Buffer Preparation (midiOutPrepare, etc.)
- done before sending message
- dwBytesRecorded and dwBufferLength are set in winmm_end_sysex
- 5. Buffer Send (to Midi device)
- uses midiStreamOutMsg()
- 6. Buffer Receive (in callback)
- 7. Buffer Empty (removing bytes from buffer)
- not applicable for output
- 8. Buffer Free (returning to the buffer pool)
- unprepare message to indicate that it is free
- SetEvent on m->buffer_signal in case client is waiting
- 9. Buffer Finalization (returning to heap)
- when device is closed, winmm_out_delete frees all sysex buffers
-
-
-Here's how input handles sysex:
- 1. Buffer Initialization (creating buffers)
- two buffers are allocated in winmm_in_open
- 2. Buffer Allocation (finding a free buffer)
- same code as simple output (see above)
- 3. Buffer Fill (putting bytes in the buffer)
- not applicable for input
- 4. Buffer Preparation (midiOutPrepare, etc.)
- done before sending message -- in winmm_in_open and in callback
- 5. Buffer Send (to Midi device)
- uses midiInAddbuffer in allocate_sysex_input_buffer (called from
- winmm_in_open) and callback
- 6. Buffer Receive (in callback)
- 7. Buffer Empty (removing bytes from buffer)
- done without pause in loop in callback
- 8. Buffer Free (returning to the buffer pool)
- done by midiInAddBuffer in callback, no pointer to buffers
- is retained except by device
- 9. Buffer Finalization (returning to heap)
- when device is closed, empty buffers are delivered to callback,
- which frees them
-
-IMPORTANT: In addition to the above, PortMidi now has
-"shortcuts" to optimize the transfer of sysex data. To enable
-the optimization for sysex output, the system-dependent code
-sets fields in the pmInternal structure: fill_base, fill_offset_ptr,
-and fill_length. When fill_base is non-null, the system-independent
-part of PortMidi is allowed to directly copy sysex bytes to
-"fill_base[*fill_offset_ptr++]" until *fill_offset_ptr reaches
-fill_length. See the code for details.

-Methods for Debugging DLLs
-========================================================================================================================
-If you have the source for both the DLL and the calling program, open the project for the calling executable file and
-debug the DLL from there. If you load a DLL dynamically, you must specify it in the Additional DLLs category of the
-Debug tab in the Project Settings dialog box.
-
-If you have the source for the DLL only, open the project that builds the DLL. Use the Debug tab in the Project
-Settings dialog box to specify the executable file that calls the DLL.
-
-You can also debug a DLL without a project. For example, maybe you just picked up a DLL and source code but you
-don’t have an associated project or workspace. You can use the Open command on the File menu to select the .DLL
-file you want to debug. The debug information should be in either the .DLL or the related .PDB file. After
-Visual C++ opens the file, on the Build menu click Start Debug and Go to begin debugging.
-
-To debug a DLL using the project for the executable file
-
-From the Project menu, click Settings.
-The Project Settings dialog box appears.
-
-Choose the Debug tab.
-
-
-In the Category drop-down list box, select General.
-
-
-In the Program Arguments text box, type any command-line arguments required by the executable file.
-
-
-In the Category drop-down list box, select Additional DLLs.
-
-
-In the Local Name column, type the names of DLLs to debug.
-If you are debugging remotely, the Remote Name column appears. In this column, type the complete path for the
-remote module to map to the local module name.
-
-In the Preload column, select the check box if you want to load the module before debugging begins.
-
-
-Click OK to store the information in your project.
-
-
-From the Build menu, click Start Debug and Go to start the debugger.
-You can set breakpoints in the DLL or the calling program. You can open a source file for the DLL and set breakpoints
-in that file, even though it is not a part of the executable file’s project.
-
-To debug a DLL using the project for the DLL
-
-From the Project menu, click Settings.
-The Project Settings dialog box appears.
-
-Choose the Debug tab.
-
-
-In the Category drop-down list box, select General.
-
-
-In the Executable For Debug Session text box, type the name of the executable file that calls the DLL.
-
-
-In the Category list box, select Additional DLLs.
-
-
-In the Local Module Name column, type the name of the DLLs you want to debug.
-
-
-Click OK to store the information in your project.
-
-
-Set breakpoints as required in your DLL source files or on function symbols in the DLL.
-
-
-From the Build menu, click Start Debug and Go to start the debugger.
-To debug a DLL created with an external project
-
-From the Project menu, click Settings.
-The Project Settings dialog box appears.
-
-Choose the Debug tab.
-
-
-In the Category drop-down list box, select General.
-
-
-In the Executable For Debug Session text box, type the name of the DLL that your external makefile builds.
-
-
-Click OK to store the information in your project.
-
-
-Build a debug version of the DLL with symbolic debugging information, if you don’t already have one.
-
-
-Follow one of the two procedures immediately preceding this one to debug the DLL.
-
-========================================================================================================================
-Why Don’t My DLL Breakpoints Work?
-========================================================================================================================
-Some reasons why your breakpoints don’t work as expected are listed here, along with solutions or work-arounds for each.
-If you follow the instructions in one topic and are still having breakpoint problems, look at some of the other topics.
-Often breakpoint problems result from a combination of conditions.
-
-You can't set a breakpoint in a source file when the corresponding symbolic information isn't loaded into memory by
-the debugger.
-You cannot set a breakpoint in any source file when the corresponding symbolic information will not be loaded into memory
-by the debugger.
-Symptoms include messages such as "the breakpoint cannot be set" or a simple, noninformational beep.
-
-When setting breakpoints before the code to be debugged has been started, the debugger uses a breakpoint list to keep
-track of how and where to set breakpoints. When you actually begin the debugging session, the debugger loads the symbolic
-information for all the code to be debugged and then walks through its breakpoint list, attempting to set the
-breakpoints.
-
-However, if one or more of the code modules have not been designated to the debugger, there will be no symbolic
-information for the debugger to use when walking through its breakpoint list. Situations where this is likely to
-occur include:
-
-Attempts to set breakpoints in a DLL before the call to LoadLibrary.
-
-Setting a breakpoint in an ActiveX server before the container has started the server.
-
-Other similar cases.
-
-To prevent this behavior in Visual C++, specify all additional DLLs and COM servers in the Additional DLLs field
-in the Debug/Options dialog box to notify the debugger that you want it to load symbolic debug information for
-additional .DLL files. When this has been done, breakpoints set in code that has not yet been loaded into memory
-will be "virtual" breakpoints. When the code is actually loaded into memory by the loader, these become physical
-breakpoints. Make sure that these additional debugging processes are not already running when you start your
-debugging session. The debugging process and these additional processes must be sychronized at the same beginning
-point to work correctly, hitting all breakpoints.
-
-Breakpoints are missed when more than one copy of a DLL is on your hard disk.
-Having more than one copy of a DLL on your hard drive, especially if it is in your Windows directory, can cause
-debugger confusion. The debugger will load the symbolic information for the DLL specified to it at run time (with the
-Additional DLLs field in the Debug/Options dialog box), while Windows has actually loaded a different copy of the
-DLL itself into memory. Because there is no way to force the debugger to load a specific DLL, it is a good idea to
-keep only one version of a DLL at a time in your path, current directory, and Windows directory.
-
-You can’t set "Break When Expression Has Changed" breakpoints on a variable local to a DLL.
-Setting a "Break When Expression Has Changed" breakpoint on a variable local to a DLL function before the call
-to LoadLibrary causes the breakpoint to be virtual (there are no physical addresses for the DLL in memory yet).
-Virtual breakpoints involving expressions pose a special problem. The DLL must be specified to the debugger at
-startup (causing its symbolic information to be loaded). In addition, the DLL's executable code must also be loaded
-into memory before this kind of breakpoint can be set. This means that the calling application's code must be
-executed to the point after its call to LoadLibrary before the debugger will allow this type of breakpoint to be set.

-A note about buffers: WinMM seems to hold onto buffers longer than
-one would expect, e.g. when I tried using 2 small buffers to send
-long sysex messages, at some point WinMM held both buffers. This problem
-was fixed by making buffers bigger. Therefore, it seems that there should
-be enough buffer space to hold a whole sysex message.
-
-The bufferSize passed into Pm_OpenInput (passed into here as buffer_len)
-will be used to estimate the largest sysex message (= buffer_len * 4 bytes).
-Call that the max_sysex_len = buffer_len * 4.
-
-For simple midi output (latency == 0), allocate 3 buffers, each with half
-the size of max_sysex_len, but each at least 256 bytes.
-
-For stream output, there will already be enough space in very short
-buffers, so use them, but make sure there are at least 16.
-
-For input, use many small buffers rather than 2 large ones so that when
-there are short sysex messages arriving frequently (as in control surfaces)
-there will be more free buffers to fill. Use max_sysex_len / 64 buffers,
-but at least 16, of size 64 bytes each.
