The Prophet VS was a hybrid 8-voice synthesizer manufactured by Sequential Circuits and released in 1986. It is notable for being the first synthesizer to use vector synthesis to structure its sound, using a joystick arranged in a "diamond" pattern for oscillator mixing. Its distinctive sound comes from mixing four 12-bit digital single-cycle waves per voice, which are then fed into analog CEM3379/3389 signal processors for filtering and amplification.
