Description

The GX-1 was Yamaha's first big polyphonic analog synth, and it was a beast! Considered the predecessor to the CS-80 (another huge poly-synth), the GX-1 featured a triple-tiered keyboard, pedalboard, ribbon controller, eight polyphonic voices and chromed pedestals. Less than 10 were ever made and have been owned mostly by legendary synth/keyboard players including Keith Emmerson, John Paul Jones of Led Zeppelin, Stevie Wonder, Rick Wright, George Fleury, Richard James of Aphex Twin, ABBA, and Hans Zimmer who bought Keith Emerson's. The two main keyboards have 61 (velocity sensitive!) keys each, and are supplemented by a smaller (3/4 scale, pressure sensitive) 37-note keyboard and a 25-note pedalboard at your feet - 184 keys total! Eight voices of polyphony plus an additional monophonic are available and can be shared and layered or split up among the different keyboards. There are also organ-style drawbars and a ribbon controller for tweaking the sounds. Additional programming buttons are hidden away under drawers and panels on the front-panel. The GX-1 used two analog oscillators per voice which are pretty much the same one's used later in the CS-80, along with a mild 2-pole VCF (filter), standard LFO and some ADSR envelopes. The GX-1 also had two "swell" pedals and a spring-loaded knee controller. It was truly a lush synth for its time, and its frequent use by many rock-legends helped cement its place in history as well as pave the way for the legendary CS-80.

The Yamaha GX-1 - it is alive

The GX-1 is basically 36 more or less identical monophonic synths (voice cards) arranged in various logical groups combined into 4 physical ranks. Each rank is controlled by various inputs such as keyboards, levers, modulation generators etc. The Solo rank consists of a single voice card. The Upper rank consists of 2 layered 8-voice...

Behringer Yamaha CS 80 clone (DS 80)

There was no way of programming the GX-1 from the instrument itself. That required an external device connected to a special Tone Board by a cable, but once that had been done, it behaved just like any preset when the instrument was being played. The other possible option was to remove one or more...
