    Sequential Prophet-6 Desktop Analog Synthesizer (Dave Smith Instruments)

    Notify me when this product is available:

    The Dave Smith Instruments Prophet-6 Desktop Polyphonic Synthesizer provides Vintage analog sound in a unit that's small enough to fit in your backpack!  The Prophet-6 Desktop is every bit as powerful as the Keyboard version.  It has all the same controls, with full-sized knobs, switches, and absolutely no menu diving!  'But how does it sound?' you may ask...well, awesome just like the keyboard, because on the inside, it’s exactly the same!


        Vintage with a Modern Twist

        Both the Prophet-6 desktop module and keyboard are 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 desktop module that’s small enough to fit in a backpack. It’s an ideal combination of portability and power for the project studio or the gigging musician.
