Powerful Synthesis
The five voices get their distinctive sound from a combination of two analog VCOs passing through a resonant 4-pole analog filter. The result is classic Sequential — smooth, warm, and weighty. Dual Digital effects ensure it can cover a wide range of sonic territory from vintage to modern.

The Perfect First Poly Synth
For customers wanting to get into analog poly synths but put off by price or complexity, it’s the perfect gateway to subtractive synthesis and the creative power of Sequential’s more advanced designs. Sequential sound and quality at a price within reach!
- Two analog VCOs per voice
- Continuously variable wave shape (sine, sawtooth, variable-width pulse) per oscillator
- Hard sync: oscillator 1 syncs to oscillator 2
- Square wave sub-octave generator (oscillator 1) per voice
- Keyboard tracking on/off for each oscillator
- Front-panel FM (frequency modulation)

- Oscillator 1 amount
- Oscillator 1 sub-octave amount
- Oscillator 2 amount
- White noise amount

- Four-pole, resonant, analog low-pass filter per voice, based on Prophet 5 Rev 4 design
- Filter can be driven into self-oscillation with the Resonance control
- Bi-polar filter envelope amount

- Two 5-stage envelope generators (ADSR + delay) with variable routing (filter, amplifier, gate)
- Velocity modulation of each envelope amount
- Envelopes freely assignable to multiple modulation destinations

- Five wave shapes: triangle, sawtooth, reverse sawtooth, square, and random (sample and hold)
- Clock sync (internal or external MIDI clock)

- One dedicated reverb with damping, pre-delay, decay and tone
- One multi-effect with stereo delay, BBD delay, tape delay, chorus, flanger, phaser, ring mod, vintage rotating speaker, distortion, high-pass filter
- Dedicated Overdrive effect

- Recreates the characteristics of vintage synthesizers by introducing micro-fluctuations in oscillators, filter, and envelopes per voice.
