Using LC to freestyle macro rotaries, I found the top 4 were not responding. The wonderful novation chatline couldn’t solve it, but pointed me at midi clashes. After a few hours investigation, I found that I’d mapped controls from the rotaries of my APCkey25 and of all things they were preset to the same midi channel & CC that LC uses (ie #9) and therefore locked four of them out via LC. Slightly miffed, but at least the problem is a known one now. I leave this for any unfortunate enough to suffer the same issue.
