Thanks a lot for your time, I really appreciate.
So, I spent hours testing, reading the manual and testing again, following thoroughly every point you described.
Highest/Lowest Note at 0, the previous note still has to be held for these conditions to work ! As if it was still waiting for a chord. So these conditions, when range is 0, are always TRUE for every consecutive note, whatever it is lower or higher than the previous.
I’ve just prepared a Cubase project with the settings you mentioned, I’d appreciate if you could take a quick look and tell me what’s wrong.
