MIDI Output to multiple channels at once?

[LarrySeyer]

I need to be able to play a MIDI file that is on channel one and send it simultaneously to all 16 MIDI channels on that track.

Was looking for a plugin that would do that, but couldn't find one.

Does one exist?

I don't know, but this JSFX might do the trick:

desc:MIDI broadcaster
slider1:1<0,16,1{Any,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}>Input Channel

@slider

ch = (slider1|0) - 1;

@block

while(midirecv(ofs, msg1, msg23) ? (
  (msg1 & 0x0F == ch) || ch < 0 ? (
    msg1 &= 0xF0;
    loop(16,
      midisend(ofs, msg1, msg23);
      msg1 += 1;
    );
  );
  1; // while
));

Awesome! Thank you!

You're welcome.

Master Tale to the rescue.

Did not test this yet, but if each midi channel would get a "mute toggle" and a transpose field, let us say -72 .. +72 modulo 128, then it would be similar to the channel multiplier function inside Sequetron, developed by Phil Tipping. Greetings to Phil also from here.

The transpose parameters can help creating an Organ with multiple pipes for example. If you add for each midi channel a different arpeggiator or some other useful midi processor, you could create more complex results from simple piano/keyboard playing, all directly, in realtime, like Vangelis.

But we can do all this already, just by combining with other available jsfx, transpose, arp ... so not really necessary.
