API

MIDI to string

JZZ.MIDI.programName(midi) -
map MIDI program value to a General MIDI instrument name.

JZZ.MIDI.programName(midi, msb, lsb) -
map MIDI program value and bank msb/lsb to a GM2/GS/XG instrument name.

JZZ.MIDI.groupName(midi) -
map MIDI program value to a General MIDI group name.

JZZ.MIDI.percussionName(midi) -
map MIDI note value to General a MIDI percussion name.

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

console.log(JZZ.MIDI.programName(24, 0, 1));
// => 'Ukulele' (GM2)

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

console.log(JZZ.MIDI.percussionName(60));
// => 'Hi Bongo'

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) -
map percussion name to a MIDI note number; if there is no exact match, try the best guess.

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

note(...) / noteOn(...) / noteOff(...) / aftertouch(...) / program(...) -
when the module is loaded, JZZ helper functions will understand the instrument names where appropriate.

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