Prophet-10 Keyboard

OSCILLATORS

• Two authentic CEM 3340 VCOs per voice
• Simultaneously selectable wave shapes. Oscillator A: sawtooth, pulse. Oscillator B: sawtooth, triangle, pulse.
• 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
• Keyboard tracking: off, half, full

FILTER ENVELOPE

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

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 (10 voices for Prophet-10) 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
• Low-pass filter cutoff expression pedal input
• Volume expression pedal input
• Sustain footswitch input

POWER

• IEC AC power inlet for internal power supply

Operates worldwide on voltages between 100 and 240 volts at 50 to 60 Hz;  Prophet-5: 20 watts maximum power consumption. Prophet-10: 28 watts maximum power consumption

PHYSICAL SPECS

• 31 lbs (14.06 kg)
• Roadworthy all-steel construction with premium black walnut heartwood body and trim
