Sequential's Prophet-10 module brings the legendary analog polysynth to your desktop with ten voices of pure vintage character. This isn't just another reissue — it's the definitive Prophet-5 experience, incorporating all three original revisions through genuine Curtis analog VCOs and filters from Rev3, plus new 2140 low-pass filters designed by Dave Rossum that mirror his original 2040 designs from Rev1 and Rev2. The Rev switch lets you choose between filter designs while adjusting the Filter Envelope's shape and response to match the original Prophet revisions.
The secret to the Prophet-10's authentic sound lies in Sequential's meticulous research into what made the original so special — those slight fluctuations and differences in response times and frequencies between voices that created the warm, organic character. The innovative Vintage knob lets you dial in this old-school randomness, from the stability of a "Rev4" all the way to the temperamental charm of the original Rev1. Classic features like Poly Mod remain faithfully intact, with Filter Envelope and Oscillator B as modulation sources affecting Oscillator A frequency, pulse width, and low-pass filter.
While staying true to the original's character, Sequential has added modern enhancements including velocity sensitivity and aftertouch for greater expressiveness, plus an improved Unison mode with configurable voice count (1-10 voices), variable detuning, and chord memory. The knob-per-function interface provides instant access to all sound-shaping controls, with 200 factory programs and 200 user programs including the original 40-program sound set from 1978. All this analog power comes housed in a compact steel case with comprehensive connectivity and premium black walnut heartwood trim.
