i play the pedal and post-ct5 manglers, and leave the bass on my lap.
what's the fun in that? just wing it like the rest of us.
a non-helpful answer: a movie that had more promise than it could live up to.
the pertinent answer: in the og firmware (from memory):
1. have the far-right toggle switch in one of the bottom two positions.
2. when the pedal is off (but powered up), press the left switch until the right light turns from blue (regular) to green (transcendence). it's quick, so watch.
3. when you turn the pedal on, it should have the green light on (right light).
4. go into record and get something in the buffer, mess with the far-left toggle switch:
a. the middle position is standard one-head operation (the bottom three knobs are for pitch/direction, aperture and so forth)
b. the bottom position is three-head operation (all three of the bottom knobs control pitch/direction for three different iterations of the loop . . . fun!)
(confused yet?)
just try it. it's my favorite thing about the pedal.
