SEQUENTIAL Prophet-10 Keyboard

Sequential Prophet-10 Keyboard — 10-voice analog polyphonic synthesizer with a 61-key Fatar keyboard, two CEM3340 oscillators per voice, a selectable 24 dB low-pass filter (SSM/SSI), Poly-Mod section, and 400 presets including classic Prophet-5 sounds.

The Prophet-10 revives the legendary sound of the original Prophet-5, expanding its polyphony and adding modern flexibility. It features a high-quality Fatar keybed with velocity sensitivity and aftertouch, driving the analog sound engine. Each voice includes two CEM3340 VCOs offering sawtooth, pulse (with PWM), and triangle waveforms, as well as white noise. The oscillators can be hard-synced and shaped via the Poly-Mod section. A key highlight is the switchable filter — choose between the vintage-sounding SSM2040 and the punchier SSI2140 filter designs from previous Prophet-5 revisions.

Modulation options include a flexible LFO with three simultaneous waveforms, two sharp ADSR envelopes, and a Poly-Mod section with Oscillator B and filter envelope as sources. The Vintage knob lets you dial in oscillator drift and behavior of older component tolerances, adding analog warmth and character. The Prophet-10 also includes Unison mode, a 440 Hz tone generator, panel mode, and comprehensive connectivity. With 400 memory slots (200 factory, 200 user) including the iconic Prophet-5 patches, this synth blends heritage with modern performance.
