JFugue 3. Loading MIDI file

An external MIDI file is loaded. Using a DAW, I created a 4-note MIDI file.

The file is loaded, and the pattern read. It should be note that velocity (in DAWs) is referred to as attack velocity (a) in the pattern string of JFugue. Also the 16 MIDI channels are referred to as V0 to V15, voice 0 to voice 15.
