This is a demo of the Yamaha GS-1 synthesizer.
The Yamaha GS-1 was Yamaha’s first digital FM synthesizer, released in 1981. It’s relatively rare 8-operator FM synthesizer (4 Carrier/4 Modulator/8 EG) that predates the DX-7 by two years.
Features of the keyboard include velocity sensitivity and polyphonic aftertouch, 16-note polyphony, a 3-band EQ and analog chorus.
The Yamaha GS-1 is pre-MIDI.
Sound On Sound’s Gordon Reid had this to say about the Yamaha GS-1:
Even today, the GS1 is a remarkable instrument, weighing 90kg (a hair under 200lbs) and designed like a miniature grand piano. It’s clear that Yamaha intended it for studio use.
But don’t let the 19th century looks deceive you. Its beautifully weighted 88-note keyboard is both velocity and poly-pressure sensitive, and — with the exception of on-board editing — it is everything you would expect from a top-of-the-range synth.

An improvised quick tour of the Yamaha GS-1. Sorry for all the blabbering ðŸ™‚ I also forgot to mention the EQ which is pretty basic bass/mid/treble.
The GS1 has eight operators per voice but these are arranged as four modulator/carrier pairs. The sound “strips” have settings for four operators on each side, so you can mix the different presets.
