Saving MIDI CC assignments in user presets?

@ustk said in Saving MIDI CC assignments in user presets?:

const var currentAutomationState = {"ChildId": "Controller", "Children": []};

Does this store MPE and Macro assignments too?

[ustk]

@David-Healey Apparently macro yes, but MPE
Here's the automation data object:

[
  {
    "Controller": 6,
    "Channel": -1,
    "Processor": "Interface",
    "MacroIndex": -1,
    "Start": 0.0,
    "End": 1.0,
    "FullStart": 0.0,
    "FullEnd": 1.0,
    "Skew": 3.106283926937945,
    "Interval": 0.0,
    "Converter": "37.nT6K8CBGgC..VEFa0U1Pu4lckIGckIG.ADPXiQWZ1UF.ADf...",
    "Attribute": "HiBoostBWKnb",
    "Inverted": false
  }
]

@David-Healey Just tested with my seaboard and yes, it works for MPE that have been MIDI learnt (Since it's just MIDI in the end...)

I'd prefer not in my case, because if you load multiple instances of the plugin, they'll all react to the same CC...

That's a very interesting point!

EDIT: actually, maybe it's fine. The DAW will only send MIDI CC to the active plugin, right?

[ustk]

@dannytaurus If by inactive you mean hidden UI, then Midi is still reaching them

[dannytaurus]

@ustk A DAW will only route incoming live controller messages to the active or record-armed track(s), surely?

So if I have 3 different synths all set to respond to mod wheel > filter, then only the active one will respond when I turn the mod wheel, right?

Regardless of whether the synth UI is visible or hidden. It's based on active tracks, right?

The other 2 'unselected', 'inactive', 'not record-armed' synths won't respond to live controller data

Otherwise there would be chaos! Unless that's what you wanted, and armed ALL tracks for record!

[ustk]

@dannytaurus Oh yes absolutely, active in the sense of "armed track", then 100% yes

[dannytaurus]

@ustk Yes, 'active' is too ambiguous a word to have used in the first place. My bad.

[ustk]

@dannytaurus The honour of badness is mine

So the working solution is

I think there's more to it, at least if you're saving/loading it from a file.

setUpdateCallback is triggered before on init and setPreCallback is only triggered when loading a preset.

So we need it to be that when we make a change to automation we save the the object to a file.
Then at init we load that object from the file using setAutomationDataFromObject
And during preload we pass the object into preset data.

[ustk]

@David-Healey Absolutely, then the mah.setUpdateCallback allows you to easily write the file, that's why I said "or just rewrite what you already saved" in the post above

[David Healey]

@ustk Yeah I've got it working now. I've set it to fall back to the preset's automation if the one loaded from the file is empty. That way I can setup my "defaults" in the preset file.

Clever!

[ustk]

@David-Healey Till today I wasn't aware of this setEnableUserPresetPreprocessing, this will save me from other situations where I was tinkering with the pre/post save/load in order to keep parameters persistent...
I'll keep that in mind now!
