Meris Ottobit Jr.

Ottobit Jr. with its sequencer opened up: sample rate, filter, bits and stutter on page 1 alongside sequencer play and multiply, then all six sequencer steps on their own knobs. The switches carry the alt functions that live behind knob combinations on the pedal itself, including the expression assignments, trigger tremolo and auto arp.

Tested with the device Somebody has run this into the gear it was made for.
