Sequential Prophet-5 Keyboard — analog polyphonic synthesizer with 5 voices, a premium 61-key Fatar keyboard with velocity and aftertouch, dual CEM3340 oscillators per voice, switchable 24 dB low-pass filter (SSM or SSI), and an expressive Poly-Mod section based on the iconic original from 1978–1984.
The Prophet-5 Keyboard is a faithful revival of the legendary analog synthesizer that shaped music history. This modern version (Revision 4) retains the warm, rich sonic character of the original while incorporating new features that elevate expressiveness and performance. The velocity- and aftertouch-sensitive Fatar keyboard delivers nuanced playability, directly affecting filter cutoff, amplifier levels, and LFO modulation.
Each voice features two CEM3340 VCOs offering sawtooth, pulse (with PWM), and triangle waveforms. Oscillator A can hard-sync to Oscillator B, which can also operate in low-frequency mode. A noise generator is available in the mixer section. The switchable 24 dB low-pass filter lets you choose between the vintage SSM2040 (Rev 1/2) and the brighter SSI2140 (Rev 3), providing tonal flexibility and authentic analog behavior.
The Prophet-5 includes a powerful Poly-Mod section, a flexible LFO with three simultaneous waveforms, two snappy ADSR envelopes, and a Vintage control that introduces subtle variations in oscillator tuning and envelope response to emulate the organic character of vintage hardware. With 400 memory slots (200 factory + 200 user), including the original 40 Prophet-5 presets, this synth balances classic analog tone with modern performance expectations.
