Playing midi files with more than 16 tracks on multiple ports

Hi, I have a midi file with 32 tracks that i want to play using this library. Using this code:

const JZZ = require('jzz');
const fs = require('fs');
require('jzz-midi-smf')(JZZ);

const filename = 'END.MID';
const midiout = JZZ().openMidiOut(3);
const data = fs.readFileSync(filename, 'binary');
const smf = new JZZ.MIDI.SMF(data);
const player = smf.player();

player.connect(midiout);
player.play();

only the first 16 tracks are played, which is expected since one midi port only can handle 16 tracks. Is there any way i can open 2 out ports and play track 1-16 in port1 and track 17-32 in port2?

Thanks!

Thanks for the help!

A simple solution would look like this:

// instead of player.connect(midiout)

player connect(function(msg) {
  (msg.track > 16 ? midiout2 : midiout1).send(msg);
});

It can be further refined to handle the ff21 metaevents from the file and automatically decide to which port to send the track data.
