i assume you mean the synthesizer -

PPG stands for Palm Products Germany, which was a company that made the first wavetable synths, which were an early style of digital synth.
the company originally made analog modular synths, but became famous for wavetable synthesis.

here's some copy and pasting to fill in the gaps:

At the heart of the PPG Wave synths were their digital wavetable oscillators. Whereas we'd been used to four or five waveforms per oscillator with analogue synths, the PPG Wave offered 64 waveforms in 30 'wavetables'. You would select a wavetable and then select one of the 64 waveforms it contained. In total, that's 1,920 waveforms per oscillator to play with!

But what was unique to the PPG Wave was its ability to modulate waveform selection within any one wavetable with a wide range of controllers.Thus you could sweep through the waveforms in any of the wavetables using envelopes, LFOs, pitch bend, modwheel, keyboard position and more. For technical reasons, these new digital synths weren't able to provide facilities we took for granted on analogue synths such as sync sweep and PWM so some of the wavetables were given over to re-creating these sounds. A fine idea in principle except.....

Waveform modulation wasn't smooth and as you swept through a wavetable's waveforms, you could hear each waveform changing abruptly from one to the other in audible steps. As a result, certain sounds (such as sync sweep and PWM) weren't convincing. Many saw this as a limitation - others (such as Tom Dolby) exploited this 'characteristic' to create totally unique sounds.

The final few waveforms of every wavetable were always sawtooth, square and pulse waves and so the PPG could do fairly decent analogue sounds as well.

But despite looking and 'feeling' like an analogue synth, the implementation of this user interface was somewhat quirky for the time.

Yes - it had a good complement of knobs to adjust the most important synth parameters but a lot of the parameters were accessed and adjusted using the numeric keypad and 'mode' keys to the right of the LCD. It was here as well that you accessed the PPG's eight-track multi-timbral sequencer.

These were all new concepts at the time that took some getting used to.

At the end of the day, though, it wasn't so much the innovative new ideas and concepts that people were paying for - it was the 'sound' of the PPG that people wanted.

The PPG sounded glorious and fresh and new - bright and tingly and with jagged sounds that could cut through a mix like a hot knife through butter. It was also equally capable of smooth, glassy, ethereal pads and much more besides and with this new, exciting pallette of sounds on offer, many musicians embraced the PPG with open arms. In fact, the list of users reads like a "who's who" of the leading artists of the time - David Bowie, The Fixx, Trevor Horn, Jean Michel Jarre, Art of Noise, Rush, Depeche Mode, Gary Numan, Robert Palmer, Psychadelic Furs, Talk Talk, The Cars, Ultravox, Steve Winwood, Rush, Stevie Nicks, Tangerine Dream, Thomas Dolby, Pet Shop Boys, Mike and the Mechanics and Stevie Wonder to name just some. Canadian band Saga, loved the instrument so much that they set up the Canadian distributorship for the product! Lesser known users include the band Freur and, of course, Hollow Sun - we once owned a Wave 2.2 and we loved it!


The first PPG Wave synths were strictly 8-bit and the coarseness of some (if not many) of the waveforms had a certain lo-fi charm that added a lot of 'edge' to the sound. In particular, the lack of any serious anti-aliasing meant that bass sounds were particularly brittle and cutting. PPG upgraded the range and the Wave 2.3 was 12-bit.

PPG also released their Waveterm (left), a separate CRT/CPU unit that gave the PPG Wave 2.3 sampling, waveform analysis, floppy disk storage and many other features to rival the Fairlight.

So.... things were looking good for PPG. Their Wave synth was unique in the market and there seemed to be no competition. Until 1983 that is....

Like most other synth manufacturers of the time, PPG had the wind knocked out of their sales with the release of the Yamaha DX7! Ironically, being digital itself, the DX7 was quite capable of emulating many of the sounds that had characterised the PPG Wave synths. It also had MIDI, had twice the polyphony and was considerably cheaper. Sadly, it looked as though the writing was now on the wall for this innovative German synth manufacturer.

Despite attempts at adding MIDI, etc., the PPG Wave synths gradually disappeared into obscurity retaining only a few devotees and an iconic status in the annals of music history. The company struggled on until 1987 when it eventually collapsed.

Many years later, however, Wolfgang Palm revived the concept successfully with Waldorf in the shape of the ingeniously named 'Microwave', a modern day take on the concept in a 2U rack mount unit. Waldorf went on to produce many other successful products whose roots lie in the innovations pioneered in the original PPG Wave synths.

I have PPG written on my Neumark 3ch mixer... the manual says it stands for "Pre Program", sort of like a PFL listen switch for the headphone mix.
