The Sequential Prophet 5 Rev3 is the final of three iterations of the original Prophet 5. All 3 models feature 2 oscillators per voice with saw, triangle, pulse and square waves. It also contains an LFO, 24db/octave low pass filter, VCA & cv/gate controls. The Rev3 differs in its use of Curtis chips, microtonal tuning capability, and can be MIDI retrofitted unlike the previous version of this model. For a more affordable, modern version of this synth, Sequential has released the Prophet 5.
