hi,
just finished a patch that works a bit like a "multitrack jam-man". it records (or loads) sound and plays it back in loop mode (also bi-directional) with adjustable start and length, with a choseable number of "tracks" to handle. documentation is included.
a bit like a stripped-down version of dieb13's LOOPOOL.
in case anyone's interested...
