Super rare resynthesis synthesizer. See this post for demos from the creator and this post for demos from Perfect Circuit. See the Acxel label for additional posts.

Description for the video above (Googlish below): "Cette vidéo a été retrouvée dans les archives de Michel Geiss, j'estime qu'elle a été enregistrée vers 1988-89.

La qualité n'est pas extraordinaire car la vidéo était enregistrée sur une cassette VHS au format NTSC et elle commençait à présenter de signes de fatigue, je l'ai numérisée moi-même.

Mais le plus important, c'est la rareté d'un tel document. En plus, c'est suffisamment rare et exceptionnel qu'il soit en langue française - québecoise."

Googlish:

"This video was found in the archives of Michel Geiss, I believe it was recorded around 1988-89.

The quality is not extraordinary as the video was recorded on a VHS tape in NTSC format and it was starting to show signs of fatigue, I digitized it myself.

But the most important is the rarity of such a document. In addition, it is sufficiently rare and exceptional that it is in French - Quebecois language. "

"This is an early 8-voice 32-program version of the instrument (serial number 813313) with the wonderful Pratt-Read J-wire keyboard, but two of the voice cards were removed before I bought it so it's currently a 6-voice.

The synth is in very good condition on the outside and exceptionally clean on the inside. See the pictures taken in broad daylight.

I began the process of repairing the instrument, but further work is needed. The unit powers up fine, all buttons light up as normal, and the autotune runs to success. But for some reason all 6 voices are making a warbled, static-y type of sound. I don't know why.

When I bought the instrument, the voices tuned and played perfectly, so I think the voice cards are fine. The left hand controller is need of repair. The levers are not functioning correctly and the plastic rate and depth knobs are missing.

This is what's been done:
Replaced most of the 4000-series logic chips on the upper and lower control boards
Replaced all keyboard bushings, fixed any broken J-wires, cleaned the bus bar and all and leveled the keys
Replaced the battery
Cleaned all pots

I am not a certified technician and it became clear to me the extent of the repairs are beyond my capabilities. This is a great synth with the rare P&R keyboard. Sadly, the time has come for me to pass the baton to someone who can complete the work."

11:32 Leafy Conclusion

There were three versions of the PPG Wave wavetable synthesizer. The first iteration was the Wave 2 (from 1981) which had 8 oscillators and the CEM 3320 VCF 24db/oct filter chips. It was in good company since the Sequential Circuits Pro One used those too for its analog filters. The next year the Wave 2.2 version came out with 16 oscillators (so two per voice) and a different filter chip to accompany its now beefier 8 voices. Both the 2.2 and 2.3 used the SSM 2044 VCF chip which was also present in the much lauded Octave Plateau Voyetra 8 and the Korg Mono/Poly. The final 2.3 iteration from 1984 increased the oscillator resolution from 8-bit to 12-bit when used in conjunction with a Waveterm A or B music computer unit which allowed for sampling and sequencing very much in the vein of the legendary Fairlight CMI.

"xFader effect (Shapers category), which allows blending L and R inputs with the desired mix Law and Tone. Also can work as a Panner if only the L input is used and a dummy plug is inserted to the R input (to break the inputs normalization)."
