Dave Smith Instruments Prophet 12 keyboard in mint condition.

The Prophet 12 is a 12-voice polyphonic synthesizer with an advanced digital/analog hybrid voice architecture capable of creating eminently playable, dynamic, and innovative sounds unlike any other synthesizer.


Specifications

Oscillators

• Five DSP-based oscillators per voice (including one sine wave sub oscillator)
• Four classic wave shapes (saw, square, triangle, sine) per oscillator
• Twelve selectable complex shapes per oscillator
• Three noise types per oscillator: white, pink, violet
• Shape modulation
• Oscillator cross modulation: frequency modulation (FM) and amplitude modulation (AM)
• Hard sync on each of the four oscillators

Character Effects

• Five high-quality digital effects. Thicken the signal and add harmonics or completely destroy the signal pre-filter.
• Girth and Air are high and low shelf equalizers with harmonic excitement. Useful for thickening and/or adding air to the signal.
• Hack and Decimate are sample and bit rate reduction algorithms which can add subtle grit or completely destroy the signal. It's harsh yet musical!
• Drive is a soft saturator for adding soft distortion and harmonic content to the signal

Filters

• Famed Curtis 2- or 4-pole resonant analog low-pass filter (self oscillates in 4-pole mode) per voice
• 2-pole resonant analog high-pass filter per voice

Feedback and Delay

• Tuned feedback
• Four-tap syncable multi delay with feedback and amount per delay per voice

Envelopes

• Four Delay + ADSR loopable envelopes (including the LPF/VCA envelopes)
• Envelopes 3 and 4 freely assignable to multiple modulation destinations

LFO

• Four syncable LFO's with phase offset and slew per LFO

Modulation

• 16 x 2 modulation matrix with over 100 mod destinations
• Modulation assignment buttons enable quick and easy modulation routing

Arpeggiator

• Sophisticated programmable arpeggiator with up, down, up+down, random, assign modes
• Re-latching arpeggiator

Programmable Distortion

• Independent programmable stereo analog distortion per layer.

Controls

• More than 50 knobs and 50 buttons enable deep and comprehensive editing with little to no menu diving.
• Backlit pitch and mod wheels are easily visible in low light situations and have a smooth yet precise feel and response.
• Independently adjustable upper and lower pitch wheel range.
• Two assignable position- and pressure-sensitive latchable touch sliders for enhanced interactivity and control.
