Get Vintage Synth Sounds with a Modern Twist with the Prophet-6 6-Voice Polyphonic Analog Synthesizer

The Sequential Prophet X is a potent fusion of samples-plus-synthesis and is Dave Smith's most ground-breaking evolution of the Prophet yet. At its heart, it's a bi-timbral, 8-voice-stereo (16-voice mono) synth with a newly developed sound engine that powers two simultaneous 16-bit, 48kHz sample-based instruments plus two high-resolution digital oscillators - all processed through analog filters. With 150 GB of internal samples from acclaimed sound developers 8Dio and all of the powerful synthesis tools you've come to expect from Dave, the Prophet X has a musical voice uniquely its own.

• True voltage-controlled oscillators, filters, and amplifiers—and adds enhancements such as studio-quality effects, a polyphonic step sequencer, an arpeggiator, and more
• 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
• The dual effects section provides studio-quality reverbs, delays (standard and BBD), chorus and phase shifter

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

At the heart of the Prophet X's powerful sound are its new, 24 dB-per-octave resonant low-pass filters, which are based on a vintage design. There are separate filters in the left and right channels for a true stereo signal path. These add exceptional presence and fullness to both the samples and the oscillators. For additional polyphony, you can switch the Prophet X from 8-voice stereo mode to 16-voice mono mode, which is useful for stacks and splits.

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.
