Is ridiculously confusing. I've poured through the manual, and followed all their instructions as to how I can make the loop playback feature work, and failed. Several times.

Apparently there's a magical step not covered in the manual.

Anybody wanna share what it is?

you mean the sampler? you set the pedal to "sampler" (its the one at the bottom) and press the pedal forward to turn it on, like you'd turn on a wah pedal. then use the 3 switch to record and the 2 switch to play or stop it.
