if you use traditional trig and cv sources to control the 'trigger' 'cv chord change' and 'volt/octave' this shouldn't be an issue. obviously it will take a decent sized patch to get this done, but it works. you just have to think of the volt/oct changes on the poly cinematic as independent from the cv input chord change on the chord pilot. have your quantized trigger come into the the volt/oct on the PC at the same time you send a separate cv modulation change to the CP to get a new saved chord. maybe time the chord change to just before the note trig to be precise.
