honestly, Im not really following this… are you saying this is only happening with CV now?
if so you can also monitor CV output levels in settings, obviously you will need to do this at a very slow speed, doing it slowly would also make it much clearer is going on.
really, you want to be slow enough to be able to see each note voltage level clearly… if you arp octaves, then this makes it easier for notes, as it’ll be one volt jumps.
not only will you be able to see the gate outputs moving, but also if the notes are stepping in 1v jumps (if using octaves) or slewing.
if I was to hazard a guess, whats is probably happening is the gate is going up/down for the ARP, but for some reason is then going high again due to you holding the pad down.
… but unclear to me if this is only for cv, and why this would happen.
have you reported this to Squarp as a bug report, this is always the best first step.
ultimately, it looks like an issue, and whilst we can discuss here to try to identify exactly the parameters of the issue - its the Squarp developers that need to understand whats going on, and then they are the only ones that can fix it.
I’ve not see anything here which would indicate its a ‘user error’, the only possiblity I see here of it not being a pyramid issue, is if its something to do witht the way your synthesizer/oscillator is reacting.
hence why Id try to test the same thing against a different synth, to see if you can replicate with other synths.
