Sequential Prophet-10 Analog Synth Module

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:

OSCILLATORS

• Two authentic CEM 3340 VCOs per voice

• Pulse width per oscillator
• Hard sync: oscillator 1 syncs to oscillator 2
• Low frequency mode (oscillator 2)
• Keyboard tracking on/off (oscillator 2)

MIXER

• Oscillator 1 amount
• Oscillator 2 amount
• White noise amount

LOW-PASS FILTER

• 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
• Filter can be driven into self-oscillation with the Resonance control

AMPLIFIER ENVELOPE

• Four-stage (ADSR) envelope generator
• Velocity modulation of envelope amount

LOW FREQUENCY OSCILLATOR

• Three wave shapes: sawtooth, triangle, square. All waveshapes can be engaged simultaneously
• 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.

AFTERTOUCH

• Channel (mono) aftertouch
• Destinations: filter cutoff frequency, LFO amount

PERFORMANCE CONTROLS

• Full-sized, semi-weighted, premium Fatar 5-octave keyboard with velocity and aftertouch
• Mod wheel
• Spring-loaded pitch wheel with selectable range per program (1 to 12 semitones up and down)
• Polyphonic glide (portamento)
• Unison (monophonic) mode with configurable voice count, from one to all five voices and key modes
• Preset switch: when off, the front panel is live; what you see is what you hear

PATCH MEMORY

• 200 user and 200 factory programs in 5 banks of 40 programs each
• Direct program access, including Prophet 5-style single-button access to the current set of 8 programs

IN/OUT

• 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-5. 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
