Bitwig has this feature for looping clips: "Operators". The recurrence operator, specifically. You can do more complicated stuff like "play this note on the 2nd & 4th loop of a 5 loop cycle".
GPU Audio is doing it with VST 3. And it's probably possible with CLAP too?
Processing audio on a GPU is a lower level issue than a plugin standard which describes the interface between the DAW and the plugin (how audio, parameters, notes, modulation data, etc. are exchanged).
These Bitwig people are always doing something exciting. Seems like they took all the stuff that makes the built-in Bitwig instruments cool (per note/voice modulation, "non-destructive" modulation) and turned it into an open plugin format.
I wonder if this brings anything cool to the table for effects plugins? Does it allow for per-voice effects?
