"- All note polyphony for lush, rich chords.
- 9 voices in two separate sections: Percussive (electric piano, clavi, piano, harmonics) and Ensemble (brass, organ, chorus, strings 1, strings2).
- Three separate oscillators.
- Overal tuning and tuners for two of the three ocillators. Tuning LEDs blink faster the further you detune each ocillator. This creates interesting phasing and chorus effects or harsh noiscapes.
- Separate stereo chorus/phase shifter on/off switch for each section.
- Interesting tremolo effect for Percussive section with rate knob for a shimmering effect.
- Joystick controls pitch bend on the X-axis and chorus phase speed on the Y-axis. It is designed to sping back to the middle of the X-axis. The Y-axis stays in position.
- Separate volume sliders for each section.
- Tone filter knobs for each section.
- Filter cutoff knob for brass sound.
- Key click adds a plunking sound to electric piano (similar to RMI Electra-Piano's "accenter" except you control the amount).
- Decay knob for Percussive voices.
- Attack and release knobs for chorus, strings 1 and strings 2.
- Stereo, mono mix and headphone outputs.
- Expression pedal input jack (can be set to either or both sections). It may require a vintage Korg pedal as it doesn't work with a modern Roland EV-5.
- Sustain pedal input.
- Keyboard trigger out."
