Saving MIDI CC assignments in user presets?

[David Healey]

@dannytaurus Aha I don't think that will help me then. The saving/loading I can do already, and I like having the fallback in the preset. The issue I have is that the updateCallbacks trigger multiple times and overwrite the data I've saved. I'll keep trying.

[dannytaurus]

@David-Healey Yeah, that's why I wanted a solution that didn't involve any plugin/preset callbacks at all.

Just wanted zero mappings saved in the presets, and a nice clean MidiMappings.js save/load script.

[David Healey]

@dannytaurus I decided to see what Claude would do with the problem. It's a massive commit so I'm not going to rely on it, but I'll leave it here as it might be a starting point for Christoph - or who knows, maybe it's perfect!

Worked on this today:

https://github.com/christophhart/HISE/commit/528ccf712722db6bb213470e40a0b4cb47f9775b

I didn't use any preprocessors but a dynamic API call - there's no need for this to be a compile-time setting.

You can define for each of macros, midi & mpe assignments whether they should be stored externally, in the user preset or in the plugin state.

@Christoph-Hart Oh nice, I'm going to dig into it this evening and try it out. Thanks!

[David Healey]

@Christoph-Hart For expansions will it use one external xml file per expansion?

[Christoph Hart]

@David-Healey you can specify the file in the onInit callback so for rhapsody it should work if the developer keeps it tidy

[David Healey]

@Christoph-Hart This system seems to work very well, haven't thoroughly tested it yet but in the standalone version of Rhapsody it's working as expected.

[dannytaurus]

@Christoph-Hart Works great here!

I'm only using it with the PluginState rather than External, which I think you're doing @David-Healey ?

SubStates: {
    MidiAutomation: "PluginState"
}

But it works great with all my scenarios.

[David Healey]

@dannytaurus Yeah this is what I'm doing

	const automationDataFile = Expansions.getAppDataFolder().getChildFile("automation.xml");
	const automationDefaults = Engine.createMidiAutomationHandler().getAutomationDataObject(); // Pulls the defaults from the project on first run

	const uph = Engine.createUserPresetHandler();
	
	uph.setStateManagerProperties({
	    SubStates: {
	        MidiAutomation: "External",
	        MPEData: "External",
	        macro_controls: "External"
	    },
	    ExternalFileDefault: {
	        MidiAutomation: automationDefaults
	    },
	    ExternalFile: automationDataFile.toString(automationDataFile.FullPath)
	});
