Sequential Pro 3 – Hybrid Mono/Paraphonic Synthesizer

The Sequential Pro 3 is a powerhouse hybrid synthesizer that combines two analog oscillators, a wavetable oscillator, and three selectable analog filters in a flexible mono/paraphonic design. With deep modulation, sequencing, and effects, it bridges the gap between classic analog warmth and modular-style sound design in a compact 37-key instrument.

Key Features

• Hybrid oscillator engine: 2 analog VCOs + 1 wavetable oscillator (32 wavetables, 16 waveforms each, wave morphing)
• Selectable filters: Prophet-6 low-pass, Moog-style ladder, OB-6 state-variable with LP/HP/BP/Notch
• Mono & paraphonic modes: Play as a powerful monophonic synth or in 3-voice paraphony
• Advanced modulation: 3 syncable LFOs, 4 loopable DADSR envelopes, 32-slot modulation matrix
• 16-track sequencer: Automates notes and parameters with up to 64 steps, 4 patterns per sound
• Dual effects: Reverb, delay (standard & BBD), chorus, phaser, plus analog distortion and tuned feedback
• Performance controls: Touch strip, pitch & mod wheels, aftertouch, and extensive real-time modulation options

Customer Benefits
