Sequential Prophet-5 Polyphonic Analog Keyboard Synthesizer

Sequential Prophet-5 is Dave Smith's timely return to the analog polysynth that changed the world. It's 'the best of all Prophet-5s,' as Dave puts it, because it embodies all three revisions of the legendary synth — Rev1, Rev2 and 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 to be like his 2040 filters found in original Rev1 and Rev2. A Rev switch lets you choose between the two filter designs. The result is as pure a renewal of an analog classic as you could wish for, with the authentic, muscular sound of the original and the roadworthiness of a state-of-the-art modern instrument. 5 voices with two authentic CEM 3340 VCOs per voice and simultaneously selectable wave shapes. Oscillator A: sawtooth, pulse. Oscillator B: sawtooth, triangle, pulse. Hard sync: oscillator A syncs to oscillator B Low frequency mode (oscillator B) Keyboard tracking on/off (oscillator B) Four-pole, resonant, low-pass filter per voice switchable between authentic versions of the Prophet-5 Rev1/2 filter and Prophet-5 Rev3 filter Three LFO wave shapes: sawtooth, triangle, square. All waveshapes can be engaged simultaneously. LFO initial amount and mod wheel control LFO destinations: oscillator A frequency, oscillator B frequency, oscillator A and B pulse width, filter cutoff Channel aftertouch with filter cutoff frequency and LFO amount destinations   Vintage sound, VINTAGE knob In addition to sourcing genuine Prophet-5 hardware components, Sequential did extensive research into exactly what made the original sound the way it did: warm, organic and alive. They found that much of this desirable character was due to slight fluctuations and differences in the response times and frequencies of the individual VCOs, filters, envelopes and amplifiers from voice to voice. To give the same mojo to the new Prophet-5, Sequential created the VINTAGE knob. Use it to dial in as much old-school randomness as you'd like, from a very stable '4' all the way up to '1,' as in Prophet-5 Rev1, the rarest and most temperamental of all Prophet-5s. POLY-MOD and enhanced Unison In addition to the unmistakable tone of its oscillators and filters, much of the classic sound of Prophet-5 was the result of POLY-MOD, which is faithfully present here as well. Modulation sources are the filter envelope and Oscillator B, while destinations include Oscillator A frequency, Oscillator A pulse width and low-pass filter. Another welcome reprise is Unison mode, which now features configurable voice count with variable detuning and chord memory. Glide works both in and out of Unison. Velocity and aftertouch Sequential couldn't resist adding a couple of modern enhancements to increase expressiveness: velocity sensitivity and aftertouch, putting filter sweeps, LFO mod and volume changes right at your fingertips. Effortless to program Prophet-5's knob-per-function front panel gives you instant gratification and immediate access to all sound-shaping controls. Toggling off the PRESET button enables live panel mode, instantly reflecting the current state of the front panel's knobs and switches: what you see is exactly what you hear. Prophet-5 has 200 permanent factory programs and 200 rewritable user programs, including the original 40-program sound set from 1978. Expandable to 10 voices With the optional Voice Expansion Card (sold separately), you can double the polyphony of Prophet-5 to ten voices. This also enables you to take advantage of bitimbral operation, which is available on 10-voice-capable Prophets. This means that you can play two different programs simultaneously. In this mode, each program is allocated five voices. Use this capability to layer two programs for thicker, more powerful pads or chord stabs. Alternatively, split the keyboard into two independent performance zones and play synth bass in the lower range and leads or chords in the upper range. The whole package All of this punchy, powerful analog goodness is housed in a full five-octave semi-weighted Fatar keyboard with USB, MIDI and CV/gate ins/outs and a premium-quality steel and hand-oiled, sustainable black walnut heartwood body.
