Pre-generated sequences
What I did was take interesting parts from an animal's genome and feed it to a
 tone generator script. This then generated a WAV file and I converted those to
 MP3, so they can be played in a browser. The last step was creating a

For communicating with Elektron, I choose pygame Python module that has MIDI
