"Never made in large numbers, the Sequential Prophet VS is now a hugely collectable synthesizer. Made in San Jose, California in 1987 (s/n 01117), the VS was Sequentials last model before the company folded. Most of the R & D team ended up in Japan, helping Korg to produce the famous Wavestation....and they sold thousands of those.....It all started in 1985, with Chris Meyer dreaming up the concept of Vector Synthesis. Initially tagged Prophet 2400, the name VS was eventually adopted. Basically, "morphing" among FOUR separate digital waveforms, with the 360* joystick, allows the creation of new patches (100 memories on board). There are 95 resident/32 user waveforms on board.....derived from 4 oscillators being shaped by Curtis analogue filters (but digitally controlled) ~ 4-pole lowpass, using 8-voice polyphony (+split/dual) ~ with twin chorus + agile stereo routing, all being sounded with a 5-octave velocity/aftertouch keyboard. As a bonus, there is also a versatile arpeggiator. Cosmetically, this synth is a bonny sight to behold, with lots of attractive blue switches and pleasing livery with SEQUENTIAL well featured on the rear...so cooool.........
This particular VS (rev 1.2) is currently on the bench being fitted with a heat sink. This is a vital addition, which prevents overheating & subsequent crashing. New blue display has been installed, and some new buttons & switches. The keys are nigh perfect, with velocity fully working, and the channel aftertouch triggering every time. KKGB rate this beauty at 9/10. Dims are 97 x 44 10 cms..weight is around 20Kgs (sturdily built with metal chassis + decent feet). 6 months full guarantee will be offered. AVAILABLE in January 2022, after extensive soak-testing. Sounds like? There are plenty demos on YouTube etc. New sonic creation is easily found; its nice to swerve away from the "normal" sounds!"
