Thanks a lot !I already did that... and I must select each track to record each part. It doesn't record each track à the same time. I heard each sound but it only record the track selected...
Thank you Rudeog.Cool idea ! But that's not a solution for a complete live. If I change tempo, pattern set (to have at least 5 pattern to make change during one song) at least 10 times it can be really complicated... I want to stop using a computer …
