The PPG Wave was an analog / digital synthesizer built by the German company Palm Products GmbH. The PPG Wave used digital waveforms and analog filters and VCAs.[1] The Wave was a combination of a synthesizer and a sequencer, with sequencer relatively advanced with the ability to influence real sounds. The PPG Wave was built in three versions: the Wave2 from 1981 to 1982, the Wave 2.2 1982 to 1984 and then the Wave 2.3.
The Wave used a Motorola 6809 microprocessor, and a variety of 6500 and 6800-series support chips. For example, MIDI support was added in 1984, by adding a 6840/6850 daughtercard[2]
Notable artists which used the Wave included a-ha, David Bowie, The Fixx, Trevor Horn, Propaganda, Jean Michel Jarre, Art of Noise, Rush, Depeche Mode, Gary Numan, Robert Palmer, Psychedelic Furs, Talk Talk, Steve Winwood, Stevie Nicks, Thomas Dolby, and Stevie Wonder.[1]
