What sets this synth apart is its binaural signal path, where 12 voices pair into 6 stereo "super voices" for genuine left-right spatial movement—think swirling pads that feel alive around you, not just panned.
At its core, dual FPGA wavetable oscillators drive the sound: the main one with a super-wavetable engine and user-importable waveforms for endless timbres, paired with a second DDS oscillator offering FM, hard sync, subosc, and PWM. Analog 24dB low-pass filter (self-oscillating with overdrive), VCA, and stereo 192kHz/24-bit Roland-style chorus/delay warm it up beautifully. Controls are knob-per-function in a clean, Roland-inspired layout, with a deep mod matrix, loopable/invertible HADSR envelope, standard ADSR, multi-wave LFOs, 64-step sequencer, and multimode arpeggiator. The black ST49 semi-weighted 49-key Fatar keybed responds with velocity and polyphonic aftertouch for per-note expression, plus two-axis bender, mod wheel, and pedal inputs—all in a sturdy 830x350x90mm chassis weighing 8kg.
Players love its pristine, flexible tones—from vintage analogs to futuristic textures—and the upgrade to factory poly aftertouch has made it a live performer's dream, though some note the sequencer could use more polyphonic lanes.
