Waldorf Electronics GmbH was founded in 1988 by Wolfgang Düren, who was then the German distributor for PPG. The name "Waldorf" refers to the German town of Waldorf, located near Bonn, the former capital of West Germany, where the company was established. Later, the company was headquartered at Schloss Ahrenthal.

After the demise of PPG in 1987, Waldorf carried forward the legacy of wavetable synthesis. Using an ASIC designed by Wolfgang Palm, the company developed the Microwave and later the WAVE synthesizers. However, Palm was never employed by Waldorf. The Microwave I, released in 1989, was based on ASICs and a Motorola MC68000 microprocessor.^[1] In contrast, the Microwave II, introduced in 1997, was powered by a DSP.

While many other synthesizer manufacturers focused on recreating existing hardware in software, Waldorf took a different approach. In 2002, they introduced the RackAttack, a hardware drum synthesizer, whose synth engine had been released as a VST instrument the year prior.

On 5 February 2004, Waldorf declared insolvency in a German court. Shortly before this, the company had been restructured into an Aktiengesellschaft (Waldorf Music AG), but the effort was unsuccessful.

In the summer of 2006, a new company, Waldorf Music GmbH, was officially established, though it is not a legal successor to the original company.^[2] Waldorf's headquarters have since moved to Remagen and are now led by CEO Joachim Flor.

In 2013, Waldorf released NAVE, a synthesizer app for iOS. Their Kyra synthesizer, launched in 2019, became the first fully FPGA-powered synthesizer.^[3] In 2014, Waldorf released the Streichfett, a synthesizer designed to recreate the sound of vintage string machines.

• Microwave: A rack-mounted wavetable synthesizer developed from the PPG Wave.^[4][5] It was produced in two hardware revisions: early models featured a backlit LCD, while later models used a lit character display. Both versions utilized different Curtis CEM analog low-pass filter chips. It was later referred to as the Microwave I following the release of the Microwave II in 1997.

• Midibay MB-15: A rack-mounted MIDI patch bay and merger.^[6]

• Microwave Waveslave: A 1U rack-mounted voice expansion module for the original Microwave, adding an additional 8 voices.^[7]

• WAVE: A wavetable synthesizer, the WAVE was a deluxe extrapolation of Microwave technology, offering additional features for wavetable creation and resynthesis that remain unmatched by any other synthesizer to this day. It was available in four colors and with 61 or 76 keys, offering 16, 32, or 48 voices, expandable to 120.^[8] Released in 1994 with a retail price of $9,000, fewer than 200 units were produced. The WAVE was used by artists such as Depeche Mode, Hans Zimmer, and The Orb.
• 4-Pole: A tabletop analog filter box.^[9]
• EQ-27: A compact, tabletop, programmable, and MIDI-controllable stereo 7-band equalizer.^[10]

• Microwave I V2.0: A ROM upgrade for the Microwave I that added additional wavetables,^[11] the ability 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, allowing users to upgrade to a full Microwave for a small fee.
• A limited edition Mean Green Machine was released alongside this upgrade. It was a Microwave with a new "Nextel" rubberized finish in green, a certificate of authenticity, special cone-shaped metal feet, and humorous silkscreening (the power switch was labeled "Life," and the card slot was labeled "Food"). From then on, standard Microwave units featured the Nextel finish in the usual blue color.

Waldorf yellow Q (1999)

• Q: A DSP-driven virtual analog synthesizer with 58 knobs. Available in bright yellow "Sahara" and WAVE blue, the latter becoming popularly known as the Halloween edition.^[21][22][23]

It offers 25 potential voices compared to the original models,^[28] due to the shared operation and effects chip. A 75-voice expansion is available, though the upgrade must be performed by Waldorf or a licensed repair center. The typical usage depends on the complexity of patches, unlike the Q or Q Rack, which feature 16-note polyphony, upgradeable to 32 voices. The microQ does not include the step sequencer.^[29]
