Sequential Prophet 5

The Sequential Prophet 5 is re-creation of Dave Smith’s analog poly synth that changed the world. It’s “the best of all Prophets” as Dave puts it because it embodies all three revisions of the legendary Prophet-5 synth — Rev1, Rev2, and Rev3 — through the use of genuine Curtis analog VCOs and filters (as in the Rev3) as well as 2140 low-pass filters designed by Dave Rossum, like the 2040 filters he designed in the original Rev1 and Rev2. A Rev switch lets you choose between the two filter designs.

The result is as pure a renewal of an analog classic as you could wish for, with the authentic, muscular sound of the original and the roadworthiness of a state-of-the-art modern instrument.

In addition to sourcing genuine Prophet 5 hardware components, we did extensive research into exactly what made the original sound the way it did — warm, organic, and alive. We found that much of this desirable character was due to slight fluctuations and differences in the response times and frequencies of the individual VCOs, filters, envelopes, and amplifiers from voice to voice.

To give the same mojo to the Sequential Prophet 5, Sequential created the Vintage knob. Use it to dial in as much old-school randomness as you’d like.

Key Features:

• Two authentic CEM 3340 VCOs per voice
• Simultaneously selectable wave shapes. Oscillator A: sawtooth, pulse. Oscillator B: sawtooth, triangle, pulse
• Four-pole, resonant, low-pass filter per voice
• Switchable between authentic versions of the Prophet-5 Rev1/2 filter and Prophet-5 Rev3 filter
• Rev1/2 filter is a Dave Rossum-designed 2140, the modern counterpart of the original 2040 filter found in the Prophet-5 Rev1 and Rev2
• Rev3 filter is a Doug Curtis-designed CEM 3320
• Recreates the characteristics of various Prophet-5 models by varying the behavior of oscillators, envelopes, amplifiers, and other parameters. Go from a very stable “4” — as in Prophet-5 Rev4, (the new version) — all the way to “1,” as in Prophet-5 Rev1, the rarest and most temperamental of all Prophet-5s.
• Mono aftertouch, Destinations: filter cutoff frequency, LFO amount
• Mono output (1 x 1/4” phone jack)
• Headphone output (stereo, 1/4” phone jack)
• MIDI in, out, and thru ports
• USB for bidirectional MIDI communication
• Control voltage in/out (1 x 1/4” phone jack) 0- +5V input/output signal. Configured for 1-volt-per-octave operation.
• Gate in/out (1 x 1/4” phone jack). Accepts a 1.5 to 15-volt on/off signal to gate the envelopes of a single voice on the Prophet-10. Outputs a 15-volt on/off used to gate the envelopes of an external synth.
• Low-pass filter cutoff expression pedal input
• Volume expression pedal input
• Sustain footswitch input
