Sequential Prophet-10 Polyphonic Analog Keyboard Synthesizer
Sequential Prophet-10 is part of Dave Smith's timely return to the analog polysynth that changed the world. It's a 10-voice synth that embodies all three revisions of the legendary Prophet-5 — Rev1, Rev2 and Rev3 — through the use of genuine Curtis analog VCOs and filters (as in the Rev3) as well as new 2140 low-pass filters designed by Dave Rossum to be like his 2040 filters found in 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.
- 10 voices with two authentic CEM 3340 VCOs per voice and simultaneously selectable wave shapes. Oscillator A: sawtooth, pulse. Oscillator B: sawtooth, triangle, pulse.
- Hard sync: oscillator A syncs to oscillator B
- Low frequency mode (oscillator B)
- Keyboard tracking on/off (oscillator B)
- Four-pole, resonant, low-pass filter per voice switchable between authentic versions of the Prophet-5 Rev1/2 filter and Prophet-5 Rev3 filter
- Three LFO wave shapes: sawtooth, triangle, square. All waveshapes can be engaged simultaneously.
- LFO initial amount and mod wheel control
- LFO destinations: oscillator A frequency, oscillator B frequency, oscillator A and B pulse width, filter cutoff
- Channel aftertouch with filter cutoff frequency and LFO amount destinations
Vintage sound, VINTAGE knob
In addition to sourcing genuine Prophet-5 hardware components, Sequential did extensive research into exactly what made the original sound the way it did: warm, organic and alive. They 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 new Prophet-10, Sequential created the VINTAGE knob. Use it to dial in as much old-school randomness as you'd like, from a very stable '4' all the way up to '1,' as in Prophet-5 Rev1, the rarest and most temperamental of all Prophet-5s.
POLY-MOD and enhanced Unison
In addition to the unmistakable tone of its oscillators and filters, much of the classic sound of Prophet-5 was the result of POLY-MOD, which is faithfully present here as well. Modulation sources are the filter envelope and Oscillator B, while destinations include Oscillator A frequency, Oscillator A pulse width and low-pass filter. Another welcome reprise is Unison mode, which now features configurable voice count with variable detuning and chord memory. Glide works both in and out of Unison.
Velocity and aftertouch
Sequential couldn't resist adding a couple of modern enhancements to increase expressiveness: velocity sensitivity and aftertouch, putting filter sweeps, LFO mod and volume changes right at your fingertips.
Effortless to program
Prophet-10's knob-per-function front panel gives you instant gratification and immediate access to all sound-shaping controls. Toggling off the PRESET button enables live panel mode, instantly reflecting the current state of the front panel's knobs and switches: what you see is exactly what you hear. Prophet-10 has 200 permanent factory programs and 200 rewritable user programs, including the original 40-program sound set from 1978.
