Born from the legendary Pearl Syncussion SY-1 of the late '70s, this expanded I/O interface breathes new modular life into Michigan Synth Works' analog drum synth, turning a classic into a Eurorack powerhouse with split stereo control.
It adds CV inputs for filter frequency or decay, split trigger inputs via stereo TRS jacks for individual channel triggering, and separate tune CV ins with V/Oct trim for precise pitch control. Outputs switch between original mixed mono or mod-split stereo via TRS 1/4" jacks, complete with adapters and cables for instant integration. Sized at 295x175x50mm and weighing 1.5kg, it mounts seamlessly to the SY-1's desktop or Eurorack format, overriding MIDI where needed for hybrid setups.
Owners love how it unlocks dynamic velocity-sensitive triggers and relative pitch offsets, making fat kicks, snares, and glitchy textures respond beautifully to sequencers—though some note the mods require careful soldering for the split config.
