VST3 / Ableton / Macro Modulation Issue

[bendurso]

I’m experiencing an issue when using a macro modulator in Ableton (with VST3 plugin only). When a macro modulator is active, you can’t change anything in the automation menu—it gets stuck.

The AU version works fine.
I tested this on Ableton 11.3.42 / macOs Sequoia 15.6.1

@bendurso Worst than that is that you can't undo redo anything, try to bypass / unbypass something, you'll see

Oh yeah, that's another issue. With VST3 and also AU.

I think the problem is that the macro modulation system interferes with the DAW's automation system.

Ideally, the DAW would ignore parameters with isPluginParameter if they have a macro assigned. But... isPluginParameter can't be set dynamically.

Is there a solution for this? @Christoph-Hart

@bendurso Is this on the latest develop branch? I feel like we've fixed this a few months ago.

@Christoph-Hart much longer than that! Gotta be a couple of years nearly!

Alright, it's fixed now, it suspends the parameter update notification when a macro modulation is present.

@Christoph-Hart Perfect. Thank you very much!

It works now! You can now go back with Cmd+Z and you can also use the track's automation panel.

The only minor issue is that if I load a preset that has macro modulation, then close the plugin window and open the track's automation, it becomes laggy again. But if I open the plugin window again, it's fixed and the parameter disappears from the automation list. Kinda weird, but not so important.
