Prophet ’08 Overview

With real analog oscillators, famed Curtis low-pass filters, and analog VCAs, the Prophet ’08 is capable of reproducing the familiar sounds of its legendary predecessors. But modern features like a greatly expanded modulation matrix and additional modulation sources—such as three envelopes and four LFOs per voice—take it way beyond vintage gear and make it a worthy and unique addition to the Prophet family tree.

Features include a gated 16 x 4 step sequencer, arpeggiator, split or stacked key modes with separate stereo outputs per layer, and rack ears for optional rack-mounting. The Prophet ’08 module can also be used as an expander to increase the polyphony of another Prophet ’08—keyboard or module—to 16 voices.

The Prophet ’08 PE (potentiometer edition) has all the features of the standard Prophet ’08, but many of the front panel’s rotary controls use potentiometers (AKA “pots”) for more “vintage-style” control. (The standard Prophet ’08 primarily uses rotary encoders.)

  • Full-featured polysynth with a 100% analog signal path.
  • Classic, real analog sound—including legendary Curtis analog low-pass filters—married to a modern feature set.
  • Compact size, huge sound.
  • Tons of knobs for direct, real-time editing and performance.
