Thanks,
I someday tried the idea of a flex machine using the rec buffer in the next part, and it works like a charm, but I like to have the overdub still active when switching bank or part/pattern… so I got back to using pickup machines, and had to get rid of the habit to use scenes for the pickup track.
I can live with it for now, as it still is heavily powerful to transition with internal + external looping/overdubbing, leading very often to unknown improvised terrotories… and forces to better live tweaking skills!
