Superbooth 2021: Waldorf M Wavetable Synthesizer, A New Generation Of The Classic Microwave


Waldorf returns to its wavetable roots with the Microwave-inspired M hybrid synth


Ahead of Superbooth 2021, Waldorf has announced that it is bringing back classic Microwave and ‘modern’ Microwave II instruments with their M wavetable synthesizer, a new desktop synth, but offers plenty of new features, as well.


Classic tone generation in a next-generation instrument.


Waldorf M is a hybrid eight-voice, four-part multitimbral synth with two wavetable oscillators. These can be switched between Microwave and Microwave II modes, behaving differently in each.



  • Two oscillator modes:
  1. Classic Microwave I mode, where 16-bit wavetables are bit-reduced to 8-bit and a 240 kHz non-anti-aliased sample rate is offered.
  2. The Modern Microwave II/XT mode offers a 40 kHz sample rate with band-limited wavetables, although both oscillators — OSC 1 and OSC 2 — offer the same panel parameters.
  • Two LFOs are available, with adjustable frequency Rate and Shape, that can be used for modulation purposes.
  • Lowpass 24 dB/Oct VCF (based on the SSI 2144 Improved Ladder Type), with resonance and analog saturation.
  • Four programmable envelopes
  • True stereo analogue VCA with panning option
  • True hard Sync (when working in its Modern Microwave II/XT mode)
  • ARP with 16 preset patterns & ability to sync to MIDI clock
  • Chord mode
  • MIDI-syncable global LFO (Low Frequency Oscillator).
  • 45 knobs and buttons for quick editing
  • Full-metal housing
  • 2,048 presets (divided into 16 banks, each with 128 sounds, including all of the classic Microwave sound sets, such as MW1 Factory Sound Set, MW1 Soundpool 1-5, the fat-sounding Analogue and Bassco, as well as PPG Wave 2.3 sounds converted for the original Microwave.
  • Connections:
  1. Six (rear panel-positioned) stereo analogue outputs — arranged as MAIN OUT (L/Mono and R) and AUX OUT (A, B, C, and D), the latter of which can be used to route each of the four Multi (multitimbral) parts to different outputs, if desired;
  2. A stereo headphone output (with an associated Volume knob in addition to the topside Master Volume knob);
  3. 5-pin MIDI IN, OUT, and THRU DIN connectors, complimented by a USB 2.0 MIDI port (for computer connection to transmit and receive MIDI data);
  4. An SD Card slot (for updating M’s firmware, importing/saving sound patches, and importing/saving M-specific data, such as user wavetables); and
  5. Kensington-compatible security lock slot.


The official intro video:


(Voltage Controlled Filter), complete with resonance and analogue saturation feature, and a true stereo analogue VCA (Voltage Controlled Amplifier) with panning option. As such, M has hybrid digital/analogue synth status.


There are 96 factory wavetables and the option to import your own, while hands-on control comes courtesy of 45 knobs and a selection of buttons, all nicely-spaced across the all-metal housing.


Other features include two LFOs, an arpeggiator, and four programmable envelopes. On the connectivity front, meanwhile, you get six stereo analogue outputs, a stereo headphone output, MIDI In/Out/Thru/USB, and an SD card slot.


The Waldorf M costs £1,879. Find out more on the Waldorf website.
