Syntakt _ Live Record ERROR?

Making a thing. dial in a completely new sound on Track 11… go to live record_ play it with 16 while sweeping a knob and it records the hit but not the sweep? What is going on here? is it because it’s 11?

I don’t have a syntakt, but if this would happen in digitakt, I would still have some questions before I could help:
-which knob/parameter exactly are you sweeping?
-did you try this in other tracks and it worked as wanted?
-are you still in the same track?
-are you recording the hits and the sweeping at the same time?
