I had a good look at the video’s, this is exactly the issue I have with my generic midi controller. Looks like a midi / software timing issue. I made two tickets for it already some time ago.
To Mixon 8 users, can you find what mapping is used? ‘scratch without touch detection’ or ‘scratch’? If it is the first, map it to the latter, maybe less problems, unfortunately also less functionality. Would be interesting to know if this is the case, since this might be the key to a solution.
Edit: Removed an outing of frustration. 
Edit: Here it was shown it is ‘scratch’. Anyway, it still looks like an ordinary timing issue that is easy to solve if companies work together …
