Nick Semrad On The Prophet-10


collapse expand iconDescription

When Dave Smith first created the iconic Prophet-5 synth, he also produced a ten-voice version with the Prophet-10. As Sequential began working on the rerelease of the Prophet-5, they decided it only felt right to recreate this original, too. With only a few in existence today, the Prophet-10 recreation of the ultrarare 1978 synthesizer is a ten-voice version of the Prophet-5. It boasts the same authentic voice and collector-worthy design as the Prophet-5, but with the power of 10.

Every Revision in One

This reintroduction embodies all three revisions of the legendary synth: the Rev1, Rev2 and Rev3. The Prophet-10 features genuine Curtis analog VCOs and filters, as used in the Prophet-5 Rev3. Elements of the Rev1 and Rev2 come out in the 2140 low-pass filters. Designed by Dave Rossum, the filters are the modern equivalent of the 2040 filters he designed in the original models. A Rev switch lets you choose between the two filter designs.

Authentic Sound

The Prophet-10 features 10 voices with two multi-waveform analog oscillators, resonant analog low-pass filters and amplifiers, and a filter and amplifier envelope per voice. Modulation is provided by a multi-waveshape LFO and Poly Mod. This groundbreaking modulation scheme allowed the filter envelope and oscillator B to be routed to a variety of destinations, including filter cutoff frequency, oscillator A frequency, and oscillator A pulse width.The original 40 Prophet-5 factory sounds are also included for a full vintage experience.

Dial In Vintage Character

For even more authenticity, the Prophet-10 includes the Vintage knob. Use it to dial in as much old-school randomness as you’d like. The knob will loosen up the oscillators and envelopes, just like they were in the good old days. The Vintage Knob recreates the characteristics of various Prophet-5 models by varying the behavior of oscillators, envelopes, amplifiers and other parameters. You can keep everything at a stable 4, as in the Prophet-5 Rev4. Or, dial in progressively more vintage character as you go all the way to 1. Here, you'll recreate the character of the Prophet-5 Rev1, the rarest and most temperamental of all Prophet-5s.

Adding a Modern Touch

When recreating the Prophet-10, Sequential took advantage of many modern enhancements. They added in velocity sensitivity and aftertouch to increase expressiveness. MIDI and USB connectivity give you more ways to connect. Control voltage and gate ins/outs let you connect modular synths and other gear.

The Prophet-10 is housed in a collector-worthy, premium steel and hand-oiled, sustainable black walnut heartwood body. A full, five-octave, semi-weighted Fatar keybed completes the look.
