Korg Monotribe analogue synth and drum machine. Fully tested: VCO (all octave settings), filter, LFO, ribbon keyboard, 8-step sequencer, and all three analogue drum parts (kick, snare, hi-hat) work as they should. Cosmetic wear consistent with use: light scuffs on the sides and a few small scrapes along the left edge beside the ribbon (shown in photos). Battery compartment is clean, no corrosion. NO POWER ADAPTER INCLUDED. Runs on 6 x AA batteries, or any 9V DC centre-positive adapter. Features: sync in/out (works with Volca, Pocket Operators, etc.), audio input, headphone and line out, built-in speaker. Ships well-packed from Ontario.
