Digitone arpeggiator question

I’m just diving deeper into the arpeggiator after largely ignoring it for a while. I’m having a strange issue with a patch I just made wherein I have tracks 1 and 2 both set up with arpeggiators running idiosyncratic arps, each parameter locked to be 32 steps.

For some reason when I try to get both track 1 and 2 to play (running these arpeggiated patterns), track 2 will simply stop playing after a few seconds while track 1 continues.

if i stop and press play again track 2 begins again and plays for another short while. I cant figure out why this is happening - is it related to voice allocation? If i mute track 1 then track 2 can play indefintiely.

any ideas whats going on here?

thanks :slight_smile:
