Update Region.cpp to support per-voice CC's #1173
Conversation
PythonBlue
changed the title
… the extended CC's with filter cutoff: the CC checks within the changed file assume unconditionally that the modulators are per-cycle controllers (Controller) whereas most extended CC's are per-voice (PerVoiceController), so added conditional statements to reflect that.
Fix applied to the CC processing: too many CC values were specified to be per-voice originally.

If we keep it like this maybe it would make sense to add an isPerVoiceController function to the extended CC list to replace both this check and the switch below in this method. However we can plan to do that after.

Shouldn't we check the region id here too in this case? If not, I'd suggest just modifying the initial check to x.source.id() == ModId::PerVoiceController || x.source.id() == ModId::Controller.

Thanks for the critiques, Paul. Insofar as this code and the one with the corresponding suggestion, good thought about the region checking, I suppose. Beyond that technicality with this particular one, I'll let you be the judge over how to format the syntax exactly: I fully admit code optimization is not my forte.
Sorry for my delayed response, btw.

Same as above, it feels like this could be a single if statement.

Figured out my issue of why I had to deviate so much with filter cutoff CC curves: it turns out the file I changed originally assumed all CC's are per-cycle controllers, whereas most of the extended CC's, including the ones I was working with, are per-voice controllers, so I added conditional statements for if it's one of those extended CC numbers. Should positively affect other targets that make use of complex CC modulation as well.
