MIDI learn menu not showing up

[d.healey]

When I right-click a knob in an existing project, it just shows the menu to assign a CC but there is no button to MIDI learn. It was working previously.

If I create a new project and add a knob there is no problem.

Any ideas? Is this happening to anyone else?

@d-healey Are you using MidiAutomationHandler.setControllerNumbersInPopup()? I've deactivated the learn feature when that function is used (to avoid learning unlisted CC numbers).

[d.healey]

@Christoph-Hart Yes I am using that feature! Ok that explains it. I suggest adding that information to the description in the api browser too.

[d.healey]

There's only 1 number I wanted to remove from the list, and I don't think it's worth giving up the MIDI learn for that. So I found a workaround :D

[Christoph Hart]

@d-healey until somebody uses the learn feature with a controller mapped to CC94 :)

[d.healey]

@Christoph-Hart Yeah but that's how it's been for the last 6 years anyway :)

I think the only other solution would be to popup a message if they try and assign a disabled controller, to tell them they can't use that one.

[Christoph Hart]

@d-healey you can attach a callback / broadcaster to MIDI learn events to display a warning.

[d.healey]

@Christoph-Hart Ooo that's a good idea, thanks!

For anyone else

	const automationHandler = Engine.createMidiAutomationHandler();
	
	automationHandler.setUpdateCallback(function(obj)
	{
		var excluded = [1];

		for (x in obj)
		{
			if (excluded.contains(x.Controller))
				Engine.showMessageBox("Internal Controller", "CC #" + x.Controller + " is used internally by the instrument. Assigning it to a control may cause issues. Please use a different controller number.", 4);
		}
	});

@Christoph-Hart is there a way to remove a CC assignment with scripting?
