I had a two-pedal JamMan that worked great. If I remember correctly, it worked like this:

While stopped (no loop recorded):

Left Footswitch — Start recording
Right Footswitch — Tap tempo

While recording:

Left Footswitch — Stop recording/start playback, start overdub
Right Footswitch — Stop recording, stop playback

While playing:

Left Footswitch — Toggle overdub
Right Footswitch — Stop playing

While stopped (loop recorded):

Left Footswitch — Start playback
Right Footswitch (hold) — Clear recording

Is it possible to add MIDI control to all parameters of the looper? I use this a lot with my Strymon Timeline and would love another MIDI-controllable looper on my board.
