The Prophet-6 Goes Modular!

Get to know them!

The Sequential Prophet-6 Module (along with its keyboard-equipped stablemate) are Dave Smith's tributes to his groundbreaking analog polysynth, the Prophet-5. The Module boasts all the same controls as the keyboard version, absent only pitch and mod wheels and keyboard transpose. 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 new poly chain feature that lets you pair any two Sequential Prophet-6s for twelve-voice polyphony. Sequential Prophet-6 Analog Synthesizer Module Features:

  • Pure, cutting-edge analog: modern, yet classic
  • Studio-grade dual effects engine
  • Poly Mod and polyphonic step sequencer
  • This synth is amazingly easy to program

Pure, cutting-edge analog: modern, yet classic At the core of the Sequential Prophet-6 Module are two newly designed, discrete voltage-controlled oscillators (reinforced by a sub oscillator) per voice. These modern analog oscillators feature continuously variable waveshapes with triangle, sawtooth, and variable-width pulse waves. Two discrete filters per voice give you Michelangelo-class tone-sculpting prowess: a four-pole, resonant lowpass (inspired by the original Prophet-5 filter), and a two-pole, resonant highpass. Voltage-controlled amplifiers complete the Prophet-6's pure-analog signal path. Studio-grade dual effects engine The Sequential Prophet-6 Module sports a dual effects section that delivers studio-quality reverbs, delays (standard and Bucket Brigade Device - aka BBD), chorus, and phase shifter. Although the effects are digital, with 24-bit/48kHz resolution, true bypass maintains your pure-analog signal path. Also onboard is a 100% analog independent stereo distortion effect. In the early 1980s, the Prophet-5's polyphony and patch memory were huge technological achievements; onboard effects were nothing but a pipe dream (if that). Poly Mod and polyphonic step sequencer One of the Prophet-5's key features was called Poly Mod, and the Prophet-6 Module carries on - with enhancements, of course. As with its predecessor, the Prophet-6's 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, lowpass filter cutoff, and highpass filter cutoff. Unison mode (featuring configurable voice count of 1-6 voices and key modes) also makes an encore. The Prophet-6's polyphonic step sequencer accommodates up to 64 steps and up to six notes per step, letting you build sequences polyphonically, with rests and external MIDI clock sync. There's also a full-function arpeggiator that you can sync to an external MIDI clock as well. This synth is amazingly easy to program Dave Smith designed the Sequential Prophet-6 Module with a knob-per-function top panel that gives you instant access to virtually all its functions. You get 500 permanent factory programs, arranged in 10 banks of 100 programs each. You can, additionally, create and save up to 500 user programs. Toggle off the Preset button and you're in Live Panel (what you see is what you hear) mode, in which the sound of the Prophet-6 switches to the current settings of its controls. We Sweetwater synth tweakers are off-the-charts ecstatic over the Sequential Prophet-6 Module. We think you will be, too! Sequential Prophet-6 Analog Synthesizer Module Features:

  • All-analog signal path; discrete VCOs and filters
  • 6 voices; 2 voltage-controlled oscillators plus a sub oscillator per voice
  • 2 discrete filters per voice: 4-pole resonant lowpass and 2-pole resonant highpass
  • Digital dual-FX section (true bypass maintains a full analog signal path)
  • Multimode arpeggiator; 64-step polyphonic step sequencer

Sequential's Prophet-6 Module is a must-have for your synth arsenal!

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
