- Filter keyboard tracking can be set to off, 1/3, 2/3 or 1/1.
- Adjustable Filter Distortion.
- LFO 1 generates a square, triangle or any of 4 different types of saw- and inverted sawtooth waveforms. LFO 1 can be routed to Filter Frequency, Osc Mod, Osc Mix, Osc 2 Pitch, Amplitude and FX section. The modulation amount can be set as positive or negative/inverted. The LFO 1 rate can be synchronized to the Master Clock.
- The LFO 1 section is used to control the rate, range and directions for the arpeggiator. Arpeggiator: Range: 1 - 4 octave. Modes: up, down, up/down, random, Poly. The Arpeggio rate can be synchronized to the Master Clock.
- LFO 2 generates a square, a regular and inverted sawtooth, LF filtered noise and random staircase waveforms. LFO 2 can be routed to Filter Frequency, Osc Mod, Osc 1 and/or Osc 2 Pitch, Pan and Pulse width. The modulation amount can be set as positive or negative/inverted. The LFO 2 rate can be synchronized to the Master Clock.
- Modulation Envelope (Attack, Decay/Release) for Osc Mix, Osc Mod, Osc 1 and/or 2 Pitch, FX section and LFO 2 amount. The modulation amount can be set as positive or negative/inverted. The Modulation Envelope can be manually triggered by the Impulse Morph buttons.
- Patterns: the cyclic waveforms of the LFOs can be replaced by a pattern behavior. There are 128 different patterns, grouped in 6 different styles.
- ADSR envelope, velocity control on/off, gain control.
- Voice modes: Poly, Legato with portamento, Mono, True Unison 1, 2 & 3.
