Overview
The PPG Wave is a hybrid wavetable synthesizer family designed by the German engineer Wolfgang Palm and released by his company PPG (Palm Products Germany) in the early 1980s. It used digital oscillators stepping through “wavetables” – sequences of stored single-cycle waveforms – combined with analog filters and amplifiers. The result was a sound that was distinctly digital in detail but warm and shapeable in finished form, very different from anything else available at the time.
Origin & History
PPG launched the original Wave 2 in 1981, followed by the Wave 2.2 in 1982 and the more refined Wave 2.3 in 1984. Each model offered improvements in sound quality, polyphony, and integration with the related Waveterm digital workstation. PPG closed in 1987, but the wavetable principle has continued through descendants including the Waldorf Microwave family of the 1990s and a wide range of modern software synthesizers, several of them developed with Palm’s involvement.
How It’s Played
The PPG Wave is played from a five-octave keyboard. Players choose a wavetable for each oscillator and then sweep through it in real time using envelopes, modulation, or controllers, producing the characteristic evolving timbres for which the instrument is famous. The signal then runs through an analog low-pass filter, which gives the digital oscillators a smooth, warm finish.
Cultural Significance
The PPG Wave became one of the defining sounds of 1980s synth-pop and electronic music. Artists including Tangerine Dream, Depeche Mode, Thomas Dolby, Trevor Horn, and Pink Floyd used it widely on landmark recordings. Its influence on later synthesizer design is enormous: wavetable synthesis is now a standard feature of mainstream software and hardware instruments.

Frequently Asked Questions
What is wavetable synthesis?
Wavetable synthesis stores a sequence of single-cycle waveforms in memory and lets the player or the modulation system step through them, producing tones that change shape over time.
Did PPG influence later synthesizers?
Yes. PPG’s wavetable approach influenced an entire family of later instruments, including the Waldorf Microwave series and many modern software synths.
