Note the EX-1 is not the pre-cursor to the GX-1. That would be the "EX-42 (1970–1977, stage model, design origin of GX-1)" according to the list of Yamaha products on Wikipedia.

"This Yamaha EX-1 organ/synthesizer is one of the rarest synthesizers in existence, as it is rumored that less than a dozen or so were ever built.

The EX-1 is easily programmed for three overall patches using a slide-out front panel,and has polyphonic glide and, on the solo keyboard, a unique side-to-side movement for modulation.

The EX-1 features two fully polyphonic keyboards (with organ tabs and polyphonic analog synthesizer sounds) which can be slaved together, a top keyboard monophonic analog synthesizer which can be slaved to the upper organ manual, and a monophonic analog synthesizer bass played from the included pedals, or slaved to the lower keyboard.

Also included is an analog drum machine, auto chord accompaniment section, and arpeggiator.

This YAMAHA EX-1 unit is in great condition.

Manufacturing date maybe 1977-1978.

All the knobs, sliders, keys and pedals work perfectly.

Also included are two TX-III tone cabinets with 14x speakers (each), bass pedals and a original matching bench.

The features of this synthesizer are much too extensive to list here.

There are a few videos on YouTube that fully detail all of the capabilities of the EX-1 Just search for "Yamaha EX-1" and prepare to be amazed.

When released in 1977, the EX-1 had a $35,000 price tag.

That's $148,000 today when adjusted for inflation.
