Allow Add System Exclusive Messages to Track

[tcdw]

On one of projects I am working on, I want to add MIDI system exclusive messages for my custom need; however, there are no way of adding that (at least officially).

After reading the source code, I found it's able to pass a object with toBytes function. So, I am using this workaround:

// add GM reset
track.addEvent({
    toBytes() {
        // Channel 1 (1 byte), message start (1 byte), message length (1 byte), message (5 bytes)
        return [0x00, 0xF0, 0x05, 0x7E, 0x7F, 0x09, 0x01, 0xF7];
    },
}); // add `as any` before the right parentheses if you using TypeScript

It would be much appreciated to add this function officially, since sometimes MIDI sysex is still need to be used.

I m curious to know how do you use this? Do you generate a midi file and play that in a DAW to transmit sysex?

Because I want to generate MIDI that using some of Yamaha XG's exclusive features (for instance, echo and aftertouch) and being able play instantly on MIDI players.

I admit it sounds like a XY Problem, since I am making a purely hobby project.

I too have a hobby project and it depends on jsmidgen. I d like sysex support too! In my usecase I want to send sysex to Disting Ex to manipulate it's settings. These are not musical setting such as aftertouch, instead they are settings of the various algorithms on it.

Maybe I should pick the project up again 🤔

Absolutely!

A TS rewrite that exports ES module would be a great next plan too!
