M4L Midi Device Dev - Having Trouble with M4L JS sending an undo to a midi clip that has just changed
Having Trouble with M4L JS sending an undo to a midi clip that has just changed
function undo() {
try {
var liveSet = new LiveAPI("live_set");
liveSet.call("undo");
outlet(1, "undo triggered");
} catch(e) {
outlet(1, "undo error: " + e.message);
}
}
in Max Console I see:
undo: undo bang
bridge: "undo triggered"
Undo function is getting triggered, but Live does not update the undo state to a midi clip. All other functions are operational in my .js code.
Funny thing, I saw this Undo live.button function actually working earlier today, and then it just suddenly stopped working.
Anyone have any ideas?
Thanks,
I fixed it, thanks to a YouTube by Tom Cosm.
The problem was all my control parameters were getting pushed onto Live's Undo Stack. Did not realize that was becoming a problem for Undo.
Every [live.dial], [live.toggle], and [live.button] with visible automation parameters pushes onto Live's undo stack when you interact with them, which buries your actual note modification under a pile of parameter changes. Setting them to hidden removes them from the undo stack entirely, leaving only the note write as the undo-able action.
