I have modified the overloop patch to add playback speed. It turned out to be more difficult than I thought because readsf does not allow different playback speed.
I have found a workaround but unfortunately I can’t get rid of the clicks on the transition from rec/overdub and playback. clicks also happen (less) on playback transition (key 1 to 2 for example).
ups… upload not possible (because I’m a new user)…
will try later
