Recording Simultaneous Parameter Changes
« on: August 11, 2022, 00:29:44 »
Hello,

Suppose I have an instrument plugin.
Its interface is four knobs, which I may twiddle simultaneously.
As far as I can tell, when recording, PC notes are only recorded for one knob.
Is there some additional setup I can do to have it record each knob's value recorded as PC notes in their own channel?

If that's not possible, what's the most idiomatic way I can modify the plugin so that performances may be recorded in OpenMPT?
I've thought about having the plugin emit MIDI messages whenever the knobs are twiddled, then using OpenMPT's MIDI mapping so that playback will trigger the same parameter changes up to quantization. It's not clear to me if that's the intended way to do it, and if so, how to best assign channels and controllers.

Indeed there is no multi-channel recording available at the moment for PC events, and there isn't really any idiomatic way to achieve this for this reason. As multichannel recording is already possible for notes, I guess one possible way to achieve this in the future would be to extend this mechanism to PC events.

That's good to know, thanks!
I've taken the liberty of adding a feature request to the issue tracker.
