The Prophet-10 Rev 4 is Dave Smith’s ten-voice version of the analog poly synth featuring all three revisions of the legendary Prophet-5 - Rev1, Rev2, Rev3 - through the use of genuine Curtis analog VCOs and filters (as in the Rev3) as well as new 2140 low-pass filters designed by Dave Rossum, like the 2040 filters he designed in the original Rev1 and Rev2. A Rev switch lets you choose between the two filter designs and also adjusts the Filter Envelope’s shape and response to match the original Prophet Rev 1/2 or Rev 3 respectively.
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
BI-TIMBRAL OPERATION
- Layer mode: two different 5-voice programs stacked together simultaneously
- Split mode: two independent, user-assignable performance zones, with a different 5-voice program assigned to each.
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 ten 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-10. 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
POWER
- IEC AC power inlet for internal power supply
- Operates worldwide on voltages between 100 and 240 volts at 50 to 60 Hz; 28 watts maximum power consumption
