A New Prophet with Deep Roots
The Sequential Prophet-6 is Dave Smith’s tribute to his groundbreaking analog polysynth, the Prophet-5. Says Dave: “It’s not a reissue, it’s vintage with a modern twist.” Driving this 6-voice beast are two discrete VCOs plus a sub oscillator per voice. Other features are two discrete filters per voice, a studio-grade, digital dual effects section, analog stereo distortion, onboard arpeggiator and step sequencer, a knob-per-function top panel, and a full-size, 4-octave, semi-weighted keyboard with velocity and aftertouch.

- Digital dual-FX section (true bypass maintains a full analog signal path)
- Multimode arpeggiator; 64-step polyphonic step sequencer
- Full-size, 4-octave semi-weighted keyboard with velocity and aftertouch
Vintage with a Modern Twist
The Prophet-6 is Dave Smith’s tribute to the poly synth that started it all—the Sequential Prophet-5. But it’s not simply a reissue of a classic. Rather, as Dave puts it, “It’s the result of our effort to build the most awesome-sounding, modern analog poly synth possible.” The Prophet-6 takes the best qualities of the original Prophet-5—true voltage-controlled oscillators, filters, and amplifiers—and adds enhancements such as studio-quality effects, a polyphonic step sequencer, an arpeggiator, and more. The result is pure, unadulterated analog tone with the stability and reliability of a state-of-the-art modern synth.
Classic Tone, Classic Vibe
Central to the warm, punchy sound of the Prophet-6 are its two newly-designed, discrete voltage-controlled oscillators (plus sub-oscillator) per voice. Continuously variable waveshapes provide the tonal palette with triangle, sawtooth, and variable-width pulse waves. There are two discrete filters per voice—a four-pole, resonant, low-pass inspired by the original Prophet-5 filter, and a two-pole, resonant, high-pass filter. Voltage-controlled amplifiers complete the all-analog signal path.
Dual Effects
The dual effects section provides studio-quality reverbs, delays (standard and BBD), chorus and phase shifter. While the effects themselves are digital, with 24-bit, 48 kHz resolution, a true bypass maintains a full analog signal path. There’s also an independent stereo distortion effect, which is 100% analog.
Poly Mod and Poly Step Sequencing
Also present from its classic predecessor is a Poly Mod section, with enhancements. True to the original, modulation sources are filter envelope and oscillator 2 (both with bi-polar control). Destinations include oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, low-pass filter cutoff, and high-pass filter cutoff. Another welcome reprise is Unison mode, which features configurable voice count (1-6 voices) and key modes. The polyphonic step sequencer allows up to 64 steps and up to 6 notes per step. You can create sequences polyphonically, with rests, and sync to an external MIDI clock. The full-featured arpeggiator can be synced to external MIDI clock as well.
Easy to Program
The knob-per-function front panel offers instant access to virtually all Prophet-6 functions. Included are 500 permanent factory programs and 500 rewritable user programs. Toggling off the Preset button enables live panel mode, in which the sound of the Prophet-6 switches to the current settings of its knobs and switches. In this state, what you see is what you hear.
Easy to Play
All of this awe-inspiring sound is packed into a four octave, semi-weighted keyboard with velocity and channel aftertouch that’s an ideal combination of portability and power for the project studio or the gigging musician.
