Back in the late 90s, this digital powerhouse was a game-changer for bridging MIDI controllers with vintage analog synths, letting you control up to 10 instruments simultaneously from a single box.

It packs four main CV and Gate outputs for channels A-D, each with independent MIDI channel assignment, portamento, and front-panel tuning trimmers plus mini pots for precise octave scaling. Eight fully programmable auxiliary CV outputs via minijack sockets join four MIDI-programmable LFOs—offering waveforms like triangle, sawtooth, square, pulse variations, and sample & hold—that can modulate any CV or aux. A 2x20 backlit LCD, data entry dial, and buttons for parameter editing, loading/storing eight user memories, plus LEDs for gate activity, MIDI data, and sync make hands-on tweaks intuitive; it even includes polyphonic mode to turn four monosynths into a 4-voice poly setup, Sync 24 out, and an optional Hz/V board for Korg or Yamaha compatibility. Housed in a sturdy metal case with rear minijack I/O, it's built to last.

Vintage enthusiasts still seek these out on the used market, praising its rock-solid tracking and flexibility for complex modular rigs, though some note the menu-diving can feel dated compared to modern interfaces.
