BRAND: Sequential 

MODEL: Prophet 5 Rev 4

FUNCTION: Keyboard Synthesizer

PRODUCT DESCRIPTION: This listing is for a Sequential Prophet 5 Rev 4 Synthesizer w/ Box & Manual. The Sequential Prophet-5 Rev 4 is the modern reimagining of the iconic 1978 analog polyphonic synthesizer, designed to embody the "best of all worlds" from its three original historical revisions. Released in 2020 by Dave Smith and the Sequential team, it pairs authentic analog circuitry with modern performance features.

SPECS:

• Serial # 1490
• Switchable Filters: A front-panel toggle lets you choose between the rich, creamy SSI 2140 filter (based on the original Rev 1/2 Dave Rossum design) and the punchy, stable Curtis CEM 3320 filter found in the Rev 3.
• The "Vintage" Knob: This dedicated control allows you to dial in the organic instability of vintage hardware. Setting it to "4" provides modern stability, while "1" recreates the temperamental character and tuning drift of the rarest Rev 1 units.
• Authentic Oscillators: It uses genuine Curtis CEM 3340 VCOs, known for their muscular tone and historical significance in the Rev 3 models.
• Expressive Playability: The Rev 4 adds a high-quality Fatar keyboard with velocity sensitivity and channel aftertouch, enabling expressive filter sweeps and volume changes that weren't possible on the originals.
• Connectivity: Features modern USB and 5-pin DIN MIDI for seamless studio integration, alongside CV/Gate inputs and outputs.
• Patch Storage: Includes 200 permanent factory programs and 200 rewritable user programs.
• Form Factor: Available as a full 61-key keyboard with hand-oiled black walnut accents or as a space-saving desktop module. 
• Polyphony: 5 voices (A 10-voice Prophet-10 version is also available with identical architecture).
• Output: Authentic Mono output (maintaining the original's signal path purity) and a headphone jack.
• Modulation: Features the legendary Poly-Mod section, allowing Oscillator B and the filter envelope to modulate Oscillator A frequency, pulse width, and the low-pass filter. 

ACCESSORIES INCLUDED: Includes original box and outside shipping box, Manual, stickers, power cord and poster
