API

All calls are identical for both Input/Output pickers except of the In/Out name suffixes where appropriate.

constructor

JZZ.gui.SelectMidiIn(options)
JZZ.gui.SelectMidiOut(options)

Can be used with or without the new keyword.
options is the obect with the following properties:

• at: (required) HTML DOM <SELECT> object to be associated with the picker.
  Either a DOM obect or its string ID.
• none: text string for the "no port opened" option.
  Default: '=== NONE ==='

select

midi_in.select(arg)
midi_out.select(arg)

Programmatically select MIDI port.
arg is an option name or any other argument accepted by JZZ().openMidiIn(arg) or JZZ().openMidiOut(arg).
e.g.:

// select the "no port" option and close the current port if it was open:
midi_in.select('=== NONE ===');
midi_out.select(); // open the default MIDI-Out port.

standard calls

MIDI Input/Output pickers are regular JZZ MIDI nodes, and therefore, can be used with all standard calls.
e.g.:

midi_in.connect(function(msg) { console.log('MIDI received: ' + msg); });
midi_out.noteOn(0, 'C#5', 127).wait(500).noteOff(0, 'C#5');
// etc...

user hooks

midi_in.onSelect(name)
midi_out.onSelect(name)

Called when the MIDI port is successfully selected; name is the port name.
e.g.:

midi_in.onSelect = function(name) {
  console.log('MIDI-In selected:', name);
};
midi_out.onSelect = function() {
  this.noteOn(0, 'C#5', 127).wait(500).noteOff(0, 'C#5');
};
