DesktopHybridPolyphonic

Launched in 2004 by the minds behind Quasimidi, this hybrid beast combined cutting-edge DSP with true analog filters at a time when grooveboxes were just starting to dream big.

At its core sits the Asynth section with 4 digital oscillators morphing seamlessly from sine to square waves, plus FM, PM, osc sync, bit reduction, and unique time linearity modulation for PWM on any shape. Sounds route through a 4-pole 24dB lowpass and 2-pole 12dB multimode analog filter, while the Dsynth delivers 32-voice polyphonic multisampling via a digital 12dB multimode filter and an 8-band fixed filterbank (plus HP/LP) for sculpting wild timbres. Ten LFOs, independent envelopes, and two independent delays sweeten the mix, all driven by a powerhouse sequencer: 32 songs with 32 patterns each, 24 tracks for notes/CV/gate, drum matrix, and per-step tricks like probability, muting, and direction. The tabletop chassis packs encoders, buttons, and an SD slot into a rack-friendly form with 8 outs and 2 ins for external gear control.

Over the years, players have hailed its sequencer as a live-performance legend—deep, intuitive, and unmatched for evolving patterns on the fly—though some note the learning curve rewards patient tinkerers with endless sound design rabbit holes. If you crave a vintage hybrid that still crushes modern sessions, this one's a timeless find.
