canāt remember where I got this, just had to go play with it to remember.
playhead is channel 1, 2, or 3. you can layer them at different speeds.
rec is record level, this will go from 1-9 and then āa-zā with āzā being the most gain. try ārā to start.
play is whether it plays forward (1) or reverse (2).
level is playback level.
rate is what rate the playback is at, modulating this creates interesting effects, 1-9/a-z with āzā being fastest.
position is where the playback starts, I think the values are also 1-9/a-z with āzā being the last position, maybe someone can confirm.
