I wrote a short tutorial for Host versus CC/MIDI automation

Hope you find this useful:

Didn't want to make this article too long, so this explore the basis imo.

Feedback is very much welcome!

CCs are supposed to be handled sample accurate with all plugins.

Parameter automation can't be handled sample accurate by VST2 (by definition of the VST2 API) it can be handle sample accurate by VST3, but AFAIK, most VST3s don't do that.

It's even more complicated with JFSX.

No idea regarding other plugin formats.

Thanks! But the resolution of Parameter automation is a little higher if I am correct compared to CC which only has 127 steps, right?

AFAIU, the resolution of an "Envelope" is so high that it never is worth discussing.

CCs can be defined to be "standard" (7 bits) an "High resolution" (14 Bit). Both is fully supported by Reaper. Plugins can adhere to high resolution if that is useful for their functionality. It's up to the plugin designer if they implement such feature.

Is there a way to check if High resolution is supported by the plugin? In the MIDI editor in Reaper I can only use 127 for a lane. Or is there another way to automated using high resolution?

When selecting CC for a "lane" in the Midi Editor, You see "More (CC0-31 14 Bit)" at the bottom and them you can select e.g. "02/34 Breath 14 Bit".
It should be written in the docs of a plugin which 14 Bit CCs it adheres to .

E.g. the "Swam" VSTIs I use can be set to use 14 Bit CC for all Midi driven parameters.

Thanks. I don't think Kontakt supports 14 bit CC.

I think you are right.

But when doing a complex instrument in Kontakt that is done by scripting, AFAIK, you can receive both parts of a High Resolution CC and combine them manually to a 14 bit value to use it as a parameter for the sound engine.
