VDR-1 Percussion Synthesizer

Imagine tapping the top of this compact synth drum to unleash a burst of analog percussion—from sharp, jarring hits to deep, tuned throbs that linger like a drone ritual. It's the kind of hands-on trigger that turns any surface into a performance tool, perfect for experimental beats in a tiny Japanese-made package.

At its core, a single VCO morphs smoothly between triangle and sawtooth waves, spanning a wide frequency range with coarse and fine tuning, plus a noise level control for added grit. The self-oscillating lowpass VCF delivers massive sweeps via cutoff and resonance knobs, while a versatile LFO—with rate, form, and separate depth controls for osc and filter—adds rhythmic life. Trigger it via the built-in piezo (just smack the case), internal mic, 3.5mm trigger input, or external piezo; sensitivity knob fine-tunes response. CV inputs modulate VCO pitch and VCF cutoff, sustain shapes attack/decay, and it runs on 9V battery or center-negative DC PSU (not included). Outputs to 1/4" mono jack.

Synth enthusiasts love its no-fuss layout and raw power for noise, drones, and percussion in modular rigs—praised for punchy, characterful sounds that stand out in JMT's lineup of minimalist boxes, though some note the single voice keeps it strictly monophonic.
