Featuring 5 additional voices in a desktop-friendly enclosure, this key-less 10-voice variation of a true analog synth legend  has been reborn and rejuvenated for the modern audience – the Sequential Prophet-10 embodies all three revisions of the legendary synth and combines them into the ultimate, comprehensive Prophet experience.

As pure and as authentic as you could hope for, this all-analog classic delivers all the sonic magic, charm and character of the original and all the state-of-the-art technology that a modern reincarnation deserves.

Boasting genuine Curtis analog VCOs and filters and a new 2140 low-pass filters designed by Dave Rossum – simply flick a switch to select between the varying designs to adjust the Filter Envelope’s shape and response to match the original Prophet Rev 1/2 or Rev 3 respectively.

Complete with modern upgrades such as velocity, aftertouch, full MIDI and USB compatibility AND a unique ‘Vintage’ control that allows you to dial in some of that vintage character, from the tempremental yet admirable Rev 1, through to the rock-solid stability of the Rev 4.

Sequential Prophet-10 Analog Synth Module Key Features:

• A Legend Reborn – The return of a classic, delivering the authentic sonic magic of the original Prophet-5 versions with added modern capabilities.
• Vintage Sound – With a newly added Vintage Knob, dial in as much old-school randomness and organic warmth as you prefer.
• Authentic CEM 3340 VCOs – Choose from two authentic Curtis analog CEM 3340 VCOs per voice.
• Poly Mod – Faithfully recreated, modulate Filter Envelope and Oscillator B to create a range of intriguing and unique sounds.
• Enhanced Unison – Individually configure each of the 10 voices withv ariable detuning, chord memory and glide.
• Modern Enhancements – Velocity, aftertouch, full MIDI and USB compatibility have all been added to the original design.
• Presets Galore – With over 200 presets built-in, create and store your own signature sounds thanks to 200 user defined presets.

Sequential Prophet-10 Analog Synth Module Specifications:

• Both Initial Amount and mod wheel control
• Mod destinations: oscillator A frequency, oscillator B frequency, oscillator A and B pulse width, filter cutoff

POLY MOD

• Sources: filter envelope and oscillator B
• Destinations: oscillator A frequency, oscillator A pulse width, filter cutoff

VINTAGE KNOB

• 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.
