Back in 1999, this synth emerged as Quasimidi's bold leap into polyphonic virtual analog territory, evolving from their rave-focused roots into a groovebox powerhouse that caught the ear of legends like Klaus Schulze and Orbital.

At its heart, it's a 4-part multitimbral beast with 8 or 16 voices of polyphony, dynamic allocation, and modes like Stack, Rotate, and Unison for thick layering. Each voice packs three oscillators—OSC1 with waves including wavetable and sync options, plus OSC2 and OSC3 using sample-based waveforms—fed into dedicated low-pass and high-pass filters with drive, resonance, and three LFOs for modulation mayhem. Hands-on knobs cover everything from PWM depth and FM rates to filter cutoffs and per-part effects like distortion, 2-band EQ, delay, chorus, and flange, all tweakable in real time. The built-in 16-step sequencer offers 8 variations across 4 parts, with muteable notes, preset phrases, and MIDI control for live performance wizardry. Housed in a compact black desktop/rack unit (with optional 19-inch ears), it stores 128 patches and 64 performances, powered by a simple 12V supply.

Owners cherish its gritty, clunky basses and morphing textures that scream electronica, though some note the learning curve and occasional pot wear after decades. It's a hidden gem for building full tracks solo.
