SY-1 Syncussion (MIDI)

EurorackAnalogDuophonic

Back in the late '70s, the Pearl Syncussion SY-1 brought raw analog drum power to stages everywhere, delivering those iconic kicks, toms, and metallic hits that defined early electronic percussion. Michigan Synth Works nails a faithful recreation with this MIDI-equipped version, blending vintage vibe with modern sequencing ease.

Each of its two voices packs dual oscillators across six modes—from single osc for pure thumps, FM for bells and cymbals, mixed tones like vibraphone, swept pitches, FM-plus-noise, to straight noise for snares. Hands-on sliders let you dial tune, decay, sweep amount and speed (up/down/off), LFO depth and rate with triangle/square shapes, plus sample-and-hold and level per voice. MIDI in via 1/4" TRS handles pitch (4 octaves as tune offset), velocity-to-trigger (16 levels, adjustable sense), pitchbend, and modwheel to filter freq, while CV inputs cover tune (1V/oct), triggers (0-8V dynamic response), and more; outputs are individual 1/4" jacks. It's desktop-sized with a sturdy build, universal 12V power, and those big, tactile controls that invite tweaking.

Synth heads love how it slots into Eurorack rigs or DAWs effortlessly, praising the organic punch and MIDI reliability that keeps classic tones alive without fuss. A few note the relative pitch needs panel tweaks for absolute tuning, but that just adds to the hands-on charm.
