Waldorf Electronics GmbH was founded in 1988 by Wolfgang Düren, who at the time was the German distributor of PPG. The Waldorf name refers to the German town Waldorf (near to the former capital of West Germany: Bonn) where the company was founded. Later, the company was headquartered in Schloss Ahrenthal. On 5 February 2004, Waldorf declared insolvency at a German court. Shortly before, the company was turned into an Aktiengesellschaft called Waldorf Music AG, but to no avail. In Summer 2006, a new company Waldorf Music GmbH was officially established, although it is not a legal successor to the original company. Waldorf's headquarter has now moved to Remagen and is led by CEO Joachim Flor.
After the demise of PPG in 1987, Waldorf took over the heritage of wavetable synthesis. Based on an ASIC designed by Wolfgang Palm, the Microwave, and later the WAVE, were built. However, Palm never functioned as an employee of Waldorf.
Over the years, Waldorf continuously adapted new technologies. While the Microwave I (released 1989) was based on ASICs and a Motorola MC68000 micro processor, Microwave II (1997) was driven by a DSP. In 2013, NAVE, a synthesizer app for iOS was released. Their Kyra (2019) is the first fully FPGA-powered synthesizer.
While many other synth manufacturers aimed to recreate previously existing hardware in software, Waldorf went the other way and presented the RackAttack, a hardware drum synth in 2002. The synth engine had been published as a VST instrument a year before. Nevertheless, the Streichfett came up in 2014: a synth that recreated the sound of vintage string machines.
- Microwave. Rack wavetable synth and developed from the PPG Wave. Built in two different hardware revisions: the first ones had a backlit LCD. The later ones a lit character display. They use a different Curtis CEM analog lowpass filter chips. Later called Microwave I due to the 1997 introduced Microwave II
- Microwave Waveslave. 1 HE voice extension for the original Microwave (adding another 8 voices)
- WAVE. A wavetable synthesizer. This was a deluxe extrapolation of Microwave technology, with additional features for wavetable creation and resynthesis that even today is not available on any other synthesizer. Available in 4 colours. 61 or 76 keys. 16, 32, or 48 voices and expandable to 120. Retail price in 1994 was $9000.00 with less than 200 made. The WAVE was used by for example Depeche Mode, Hans Zimmer and The Orb.
- 4-pole. Table top analog filter box.
- EQ-27. Compact (table top) programmable and MIDI controllable stereo 7 band equalizer.
- Microwave I V2.0 ROM upgrade, which added additional wavetables, a facility to algorithmically create custom wavetables, a speech synthesizer, and numerous other improvements. The Waveslave was not compatible with this upgrade, but a trade-in program was offered where the user could upgrade to a full Microwave for a small fee.
- A limited edition Mean Green Machine was released at the same time as this upgrade, being a Microwave with a new "Nextel" rubberized finish in a green color, a certificate of authenticity, special cone-shaped metal feet, and comical silkscreening (the power switch was labeled Life, and the card slot was labeled Food.) Normal Microwave units from then on featured the Nextel finish in the usual blue color.

- PPG 2.V VST plug-in synthesizer to emulate the blue PPG. wave 2.x wavetable synthesizers
- microQ. Even more compact and affordable Q rack with only 7 knobs and different DSP. Differences: 25 potential voices compared to the original models, due to shared operation and effects chip. A 75 voice expansion is available. The upgrade must be done by Waldorf or licensed repair center. Typical usage depended upon complexity of patches, unlike the Q or Q Rack which feature 16 note polyphony, upgradable to 32 voices. The microQ did not include the step sequencer.
