Thank you very much for your reply and for your work on the firmware. In fact, this is the version I am planning to use.

I would like to know if you have any information regarding the behavior of pattern modulation via CV. If the track controlling the patterns is on a clock division of 16, will the pattern change correctly at the start of each new pattern? Also, is the pattern switching instantaneous when triggered via CV?

Well, I don't think this behaves like a queued pattern change that always waits for the next pattern start. From what I understand, the pattern changes when the CV value changes and the routing is processed. So if your control track changes value every 16 steps, the pattern should change around that moment, but I wouldn't want to promise perfect "change exactly at the next pattern boundary" behavior. At the moment I don't have time to test this specific setup, so I'd treat it as supported in principle, but not guaranteed as a tight synced pattern-switching feature. I'd suggest moving this discussion to the Modwiggler forum, where maybe you can find other people interested in this specific behavior and ready to test it:
