engine.openMidiOut(arg) - try to open MIDI-Out port.
port = JZZ().openMidiOut(0);
port = JZZ().openMidiOut('Microsoft GS Wavetable Synth');
port = JZZ().openMidiOut(['Microsoft GS Wavetable Synth', 'Apple DLS Synth', 0]);
port = JZZ().openMidiOut(function(){ return [2, 1, 0]; });
port = JZZ().openMidiOut(/Yamaha/);
port = JZZ().openMidiOut();
port.info() - get an info object with the following keys:
port.name() - a shortcut for the port.info().name.
JZZ().or('Cannot start MIDI engine!')
.openMidiOut().or('MIDI-Out: Cannot open!')
.and(function(){ console.log('MIDI-Out:', this.name()); });
Initially, all MIDI-Out nodes are created in MIDI 1.0 mode. Use MIDI2() to switch the mode to MIDI 2.0, and MIDI1() to switch it back to MIDI 1.0.
port.MIDI2() - set MIDI 2.0 mode for all subsequent chained calls.
port.MIDI1() - set MIDI 1.0 mode for all subsequent chained calls.
Additionally, MIDI1() and MIDI2() clear off the default group, channel, sxId and MPE status (see below), and can be used for this purpose.
port.send(msg) - send MIDI message to the port.
msg can be an array, a comma-separated list, or an object of type JZZ.MIDI or JZZ.MIDI2, depending on MIDI 1.0 or MIDI 2.0 mode of operation.
It is subject of the same rules applied to the JZZ.MIDI/JZZ.MIDI2 constructors.
port.send(0x90, 0x3c, 0x7f) // 90 3c 7f -- Note On, MIDI 1.0
.MIDI2() // enable MIDI 2.0
.send(0x20, 0x90, 0x3c, 0x7f) // 20903c7f -- Note On, MIDI 2.0
.send(0x90, 0x3c, 0x7f); // error!
MIDI-Out port has a complete set of helpers corresponding to the ones defined in JZZ.MIDI.
Roughly speaking, for each helper name, port.helper(...) is equivalent to port.send(JZZ.MIDI.helper(...)).

Additional helpers can send multiple messages:
port.note(c, n, v, t) is equivalent to port.noteOn(c, n, v).wait(t).noteOff(c, n) if t > 0, and to port.noteOn(c, n, v) otherwise.
In MIDI 2.0, all above helpers require an additional first parameter group and produce MIDI 1.0 messages wrapped into Universal MIDI Packages (UMP).
Standard MIDI File Meta Events (MIDI 1.0 only) can also be sent down the pipeline:
smf smfSeqNumber smfText smfCopyright smfSeqName smfInstrName smfLyric smfMarker smfCuePoint smfProgName smfDevName smfChannelPrefix smfEndOfTrack smfTempo smfBPM smfSMPTE smfTimeSignature smfKeySignature smfMetaEvent
All statements below do the same job:
port.send([0x90, 61, 127]).wait(500).send([0x80, 61, 0]); // arrays port.send(0x90, 61, 127).wait(500).send(0x80, 61, 0); // comma-separated port.send(0x90, 'C#5' ,127).wait(500).send(0x80, 'Db5' ,0); // note names port.noteOn(0, 'C#5', 127).wait(500).noteOff(0, 'B##4'); // helpers port.note(0, 'C#5', 127, 500); // another helper
Similarly to MIDI 1.0 helpers, these are defined in JZZ.MIDI2.

port.gr(group) - (MIDI 2.0 only) - set default group for all subsequent chained calls.
group - group number (from 0 to 15), or nothing. If called without parameter, removes the default group.
port.ch(chan) - set default channel for all subsequent chained calls.
chan - channel number (from 0 to 15), or nothing. If called without parameter, removes the default channel.
Can save some typing if multiple messages are sent to the same MIDI channel.
These statements are equivalent to the ones in the previous example:
port.ch(0).noteOn('C#5').wait(500).noteOff('C#5'); // default velocity 127 can be omitted
port.MIDI2.gr(0).ch(0).noteOn('C#5').wait(500).noteOff('C#5');
port.sxId(id) - set the default SysEx ID for all subsequent chained calls.
id - 7 bit SysEx ID, or nothing (default: 0x7F).
port.sxId(8).sxMasterTuningA(216); // sends: // f0 7f 08 04 04 00 34 f7 // f0 7f 08 04 03 55 2b f7
port.mpe(m, n) - (MIDI 1.0 only) - start MPE mode for all subsequent chained calls.
m - master channel (from 0 to 14).
n - number of note channels (MPE zone size).
If called without parameters, returns to regular operation.
In MPE mode each note will be assigned to its own channel while there are enough channels.
Each channel can be separately controlled with its own pitchBend() and other messages.
Certain messages like program() are common for all notes and must be sent to the master channel.
Some messages like pitchBend() can be sent both to the master channel and to the note channels.
To send message to the master channel, omit the channel number in the corresponding helper call.
To send message to a note channel, substitute the channel number by the note when calling the helper.
NOTE: some calls may be ambigious if the function accepts variable number of arguments.
This can be fixed by adding undefined in the end of the argumant list.
e.g.
port.mpe(0, 4).bank(1, 1) - goes to the master channel;
port.mpe(0, 4).bank(1, 1, undefined) - goes to the note channel.
port.mpe(0, 6).program(25) // program change on master channel (0)
.noteOn('E4').noteOn('A4').noteOn('E5') // channels 1, 2, 3
.noteOn('A5').noteOn('C#6').noteOn('E6') // channels 4, 5, 6
.wait(500).pitchBend('C#6', 64) // pitch bend on channel 5
.wait(500).pitchBend(10) // pitch bend on master channel
.wait(500).noteOff('E4').noteOff('A4').noteOff('E5')
.noteOff('A5').noteOff('C#6').noteOff('E6');
port.close() - close the port.
No other calls except the common calls can be chained to the closed port.
This call is optional, since all ports automatically close on exit.
port.or(), port.and(), port.wait()
