"1970's YAMAHA EX-2 ANALOG SYNTHESIZER ORGAN. Their (sic) were only 12 of these made and it is very rare. It does work, but i dont know how to operate it. Speaker is missing its felt cover in the back, but does have a replacement for it. Pick up only in Pahrump, Nv 89060."
You can find a demo of one here. Note the EX-2 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.
"The WAVES module adds classic Wavetable synthesis to the sound palette of Tera Pro. It’s an optional module which you can purchase separately. Wavetable synthesis is a sound design technique which uses morphing oscillator waves to create sounds.
Wavetables can store a variable number (From 1 to 1024) of different frames/waves, allowing you to scroll through from one wave to the next, creating a new level of movement in your sound design. This movement can be stepwise as in the famous early PPG synths or smooth (using interpolation) and antialiased for a polished modern sound. Tera Pro WAVES allows you to explore this entire range.
WAVES allows for different waveform frame sizes in the range of 128 up to 4096 samples per cycle and up to 1024 frames. More than a thousand public domain wavetables covering most areas are already included in WAVES, and more can be added by the user.
