# PPG Wave 2.3 Rackmounted Project Machine

PPG, PPG Wave @ 12 March 2019

“I have a significant amount of time [both mine and others] and money invested in making this work.
I am at my limits of abilities to work on it. I can get a display to run but no sound because of the Proz-mismatch.

The PPG has the latest Virtual Music 8.3 ROMs. I am including a second set of ROMs as well.

I would refer to this below from Alexander from Virtual Music https://www.virtual-music.at/en/ppg-zone/#1

When this was shipped, the cards were not removed and wrapped so the damages are listed below.
• 2-3 broken mylar caps [the leads are hairline thin and very fragile]
• 1 broken 27.460mhz Crystal
• LCD cable pins are bent / broken and some will need replacement.

Details from the original listing[s]:We don’t know much about this. What we do know is it doesn’t work. It would appear that someone took a PPG Wave 2.3, removed the PCB’s, display, knobs and power supply and re-mounted them in a rack-style case. The front panel has a very professional looking blue and white transfer so whoever did this was quite serious about it. It also comes with the Wave’s original Mod Wheel assembly which can be connected to the internal motherboard. We tested it and this is what we found: It appears to boot up and display what looks like sensible information on the LCD (see photo). It accepts commands from the front panel, such as program or Midi channel changes, or for example pressing the Analog button brings up the current front panel knob-settings in the display and these can be altered in real time. It also appears to have valid data in memory judging by the parameters when the program number is changed. It can also be switched to emulate PPG Wave 2.2 mode. So far, so good. Now the bad news: plugging in a Midi keyboard produces no output, so either the Midi circuitry or the sound-generating section has a problem. Without having another Wave to test it with against, that’s as much as we know. Ideally this would suit a PPG enthusiast who has a working Wave 2.3 and can diagnose this one using an external Wave keyboard and card substitution. **SO SOLD AS IS!!** IEC mains connector with switchable 110/240V supply. ” Click here to visit listing on eBay
