API functions for setting learned plugin parameters

[lb0]

Hi,

Another request that I think would benefit scripters and open a whole new level to using controllers with Reaper.

Simply an API to set unset learned plugin parameters.

eg:

TrackFX_Learn(track, fxnum, param, midichan, msgtype, mode, flags)

- learns controller mapping to fx parameter.

TrackFX_UnLearn(track, fxnum, param)

- unlearns all assignments to param.

and maybe an additional:

MidiLearn_UnmapAll()

Having this available (not using the chunk - too slow on many sample instrument tracks - especially when you may have duplicate mappings across plugins) - we could create scripts (like Smart Knobs) - which can directly map to plugin parameters (and not rely on doing the parameter setting through the script which loses resolution) and have dynamic assignments making the controllers more versatile.

I know this can already be done using the track chunk - but if you have Kontakt or similar on a track - using the chunk really slows things down.

Huge +1, since I’m using a lot of Kontakt.

How big are the StateChunks usually, when you use Kontakt?

@devs:

Alternatively, as I'm already in the process of making functions to do that, I would suggest Get/SetFXStateChunk-functions for TrackFX and TakeFX.

I think this would be much faster, as only the FXChain-related changes would be committed, not all Track-States.

If you could add them, this would help me great tons making my ParmLearn-functions fast and reliable.

Yes - +1 - but I still want direct API into midi learning system.

But direct FX chunk API would be utterly fantastic for many reasons!
