JZZ.MIDI.groupName(midi) -

console.log(JZZ.MIDI.programName(60));
// => 'French Horn'

console.log(JZZ.MIDI.programName(24, 0, 1));

console.log(JZZ.MIDI.groupName(60));
// => 'Brass'

console.log(JZZ.MIDI.percussionName(60));

string to MIDI

JZZ.MIDI.programValue(str) -
map instrument name to a MIDI program (GM only); if there is no exact match, try the best guess.

JZZ.MIDI.noteValue(str) -

JZZ.MIDI.guessValue(str) -
map program or percussion name (whatever matches best) to a MIDI value; if the return value is negative, it's the percussion note value with a minus sign, otherwise, it's the program value.

console.log(JZZ.MIDI.programName(JZZ.MIDI.programValue('piano')));
// => 'Acoustic Grand Piano'

console.log(JZZ.MIDI.percussionName(JZZ.MIDI.noteValue('snare')));
// => 'Acoustic Snare'

var n = JZZ.MIDI.guessValue('crash');
if (n < 0) console.log(JZZ.MIDI.percussionName(-n));
else console.log(JZZ.MIDI.programName(n));
// => 'Crash Cymbal 1'

list all instruments

allGM2() / allGS() / allXG() -
return a complete list of GM2/GS/XG programs as an array of of triplets [program-number, bank-msb, bank-lsb].

JZZ helpers

  .ch(0).program('accordion').noteOn('C#6', 100)
  .ch(9).noteOn('cowbell', 127);
