Allows you to build midi datasets.

The code creates MIDI files with unique chords (one chord in a file; any instrument) with random duration and velocity. Names of such files are notes' midi-numbers splited by ','. For e.g. "40,45,51.mid".

This code creates 3000 MIDI! Rewrite it to get less files.

Splits big MIDI file into little MIDI files by notes minimum duration. Names of such files are files' indexes and notes' midi-numbers, all splited by ','. For e.g. "1,40,45,51.mid".
