Sequential Prophet 6

The Prophet 6 from Sequential is not just a reissue of one of the most coveted synthesizers in history, the Prophet 5. It is a wholly new beast, sharing only the most important thing, excellent sounding analog synthesis. The Prophet 6 has two redesigned discrete VCOs per voice, providing continuously variable waveshapes for maximum beef. With 12 oscillators in all there will be no shortage of richness in tone. Also included is a suboscillator for filling out the bass frequencies, not using the traditional square wave but instead a more tasteful and smooth triangle wave. The filter is inspired by the original Prophet-5 filter, with discrete circuitry, providing four-pole resonant lowpass cutoffs.

One important design specification that the Prophet 6 wanted to maintain is the one knob per parameter function, which prevents menu-diving and "woops" moments. With huge amounts of presets, one can quickly move between patches without having to adjust every knob.

Included in the new Prophet 6 is a bank of stereo effects, utilizing 24-bit, 48 kHz resolution. In has studio-quality delays (including standard and BBD), reverbs, chorus, and phase shifter. When bypassed, it maintains the fully analog signal path. A stereo distortion is also included that is full analog.

For pitch control, the Prophet 6 has built in arpeggiators and sequencers. The sequencer can program 64 steps (with 6 notes per step for chord sequencing.) The arpeggiation patterns can be adjusted from up, down, up-down, random, etc.

With a full size keyboard and semi-weighted keys, piano players will have an easy time transferring skills. It has velocity and aftertouch sensitivity and looks great on the stage or in the studio.

Introducing the Sequential Prophet-6
Sequential is back! 100% analog signal path with discrete voltage controlled oscillators, filters, and amplifiers.

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 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 in 10 banks of 100 programs. In addition to these, you can create and save up to 500 user programs of your own. 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 portability and power for the project studio or the gigging musician.
