When Sequential Circuits finally went belly-up, their research and development into vector synthesis was picked up at Korg. This led to the hugely successful Wavestation Synthesizer which was based on Sequential's ProphetVS. The Wavestation incorporated the 2-dimensional vector joystick of the ProphetVS which allowed the user to alter and animate sounds.

Korg added to this a second break-through form of synthesis: wave sequencing, by which short segments of sampled audio waveforms could be played one after the other and cross-faded into each other for some complex and unusual tones, pads, textures and rhythms. The Wavestation had 2MB of ROM based samples at your disposal. Programming is not exactly easy but this great digital synth is capable of lush ambient sounds and strange effects. It has the obligatory lowpass filter, though it is non-resonant and digital sounding. Also on-board are some multi-effects which are pretty nice. This synth is easily upgraded and expandable with PCM cards too.

In 1991 the Wavestation EX, also called EXK-WS, was released (pictured above). The EX added 150 more waveforms (4MB) including acoustic instruments and drums. The EX also adds 8 multi-effects including: Mod Pitch Shift-Delay, Stereo Compressor-Limiter/Gate, Vocoder, Overdrive and Distortion effects, transposable keyboard and added MIDI implementation and control. Wavestations are used by Orbital, The Future Sound of London, Genesis, Jan Hammer, Depeche Mode, Toto, Vangelis, Legendary Pink Dots, Biosphere and Sin.
