• Programmable Pitch bend range, up to +/- 4 octaves

• Separate up/down bend range: -12 or -24 semitones, + 2 semitones
• 1 pedal input for sustain.
• 1 pedal input for expression pedal.

• Oscillator models of multiple waveforms (traditional analog, extended analog, pulse waveforms, real-time algorithmical waveforms with additive-, FM- and formant- synthesis)

• OSC config knob 11 categories (Pitch, Shape, Osc Sync, Noise Mix, Osc 2 Detune, Sine Mix, Tri Mix, Saw Mix, Square Mix, Freq Modulation, Amp Modulation)

• Multi-mode filter with 12 dB (2-pole) low pass, 24 dB (4-pole) lowpass and band pass, high pass, Ladder M and Ladder TB characteristics.
• Cut off, Resonance, envelope amount, envelope amount controlled by velocity.

• ADR/ASR envelope.
• Filter keyboard tracking can be set to off, 1/3, 2/3 or full.

• Adjustable Filter Distortion.

• LFO generates a triangle, square, sawtooth, inverted sawtooth or sample and hold waveforms. LFO can be routed to Filter Frequency and Osc mod. The LFO rate can be synchronized to the Master Clock.
• LFO can be switched to polyphonic Env mode with four different characteristics and sample and hold is manually triggered by keyboard (polyphonic S/H). 

• Arpeggiator: Range: 1 - 4 octave. Modes: up, down, up/down and random. The Arpeggio rate can be synchronized to the Master Clock.

• ADR/ASR envelope, velocity control on/off, inverse envelope on/off.

• ADR/ASR envelope, velocity control on/off, gain control.

• Individual Pan-control per program

• Voice modes: Poly, Legato with portamento, Mono, True Unison 1, 2 & 3.

• Four program slots for layering possibilities and multitimbrality.

• Delay section with tap tempo, four stages of feedback, stereo ping-pong, dry/wet mix. The Delay speed can be synchronized to the Master Clock.

• FX section with Flanger, Phaser, Ring Modulation, Chorus, Ensemble and Drive.

• Reverb section with five algorithms (Room, Stage 1, Stage 2, Hall 1, Hall 2).

• Programs (single sounds): 8 x 50 (400) locations

• Performances (multi sounds): 4 x 50 (200) locations

• 4 outputs. Each slot can be assigned to its own output.

• Headphones output.

• High resolution low noise 24 bit DACs.

• All control knobs and switches send and receive control change messages.
• System exclusive bulk dumps. One program or all programs.

• Master Clock will sync to incoming MIDI clock.
