a bit confusing, but here goes, by track 1 and 2 and by mentioning CV i’m surmising you don’t mean that you’re feeding the CV output with note info from the Track1 of the A4 (which you can do)
so i’m guessing that you are deriving both CV outs from the same CV sequence, CV out pairs, if sequencing should work from different tracks, for conventional usage, so you can use the FX track to sequence CV out pair 2
otherwise you’re gonna have to look at your poly settings and unison and all the poly modes, but i can’t work out why you’d mention cv in if that’s the case - or why that would mess things up -can you be clearer !?
