"This is a rare but very cool find. It's in excellent working condition and in very good shape aesthetically considereing its age! It was used by a world class film composer. You probably would hear sounds from this unit in some of his earlier film scores. Power cord is included but no manual. Vector Synthesis is a type of audio synthesis introduced by Sequential Circuits in the Prophet VS synthesizer during 1986. The concept was subsequently used by Yamaha in the SY22/TG33 and similar instruments and by Korg in the Wavestation. Controlling the mix of four sound waves by defining a point on a vector plane using a joystick The Prophet VS vector synthesizer, which was Sequential's only digital synthesizer, came out in early 1986. Boasting a synthesis scheme known as vector synthesis, it combined the revolutionary digital waveform generator and vector joystick to the tried and proven analog Curtis filter, and resulted in a unique instrument with a very distinct sound. It still sees heavy use today despite its reliance on rare custom components with a high failure rate. Vector synthesis provides movement in a sound by providing dynamic cross-fading between (usually) four sound sources. The four sound sources are conceptually arranged as the extreme points of X and Y axes, and typically labelled A, B, C and D. A given mix of the four sound sources can be represented by a single point in this 'vector plane'. Movement of the point provides sonic interest and is the power of this technique. Mixing is frequently done using a joystick, although the point can be controlled using envelope generators or LFOs. "
