I did try implementing a scrub control with the crank but it’s just not possible with the way the Lua audio API works in Playdate. TapeLooper would need to be rewritten in C to do that I think, not an easy task.
I know there’s a music box app for Playdate that does work with the crank, but that’s triggering samples as you turn - much simpler than dealing with sample frames in a file/buffer.
understood - and you are at the forefront of music creation on the playdate. I was asking because I saw a pedal that could play a sequence with a rotary dial on a cassette and I realized that the play date could do same thing ! Thanks for your reply - appreciated :)
