When sequencing, notes lengths won’t be recorded correctly (even when manually step edit it). For example, if I play a note one bar and a half (whatever the quantization), the note will, half of the time, be recorded on two full bars (and the sample is gated). The same if I enter the note in step seq, the same note will auto adjust itself to fill the bar. This does’nt happen everytime, but randomly.
I’ve never had this issue. Did you update to the latest version? If you can make a video, it’s always helpful to better illustrate the problem.
