[embedded content]

Ahead of Superbooth 2021, Waldorf has announced that it is bringing back classic Microwave and ‘modern’ Microwave II tone generation with their M wavetable synthesizer

The Waldorf M is described as a “new-generation classic hybrid wavetable synthesizer”, with an analog lowpass 24dB/Oct VCF with resonance and analogue saturation, true stereo analogue VCA and more.

Here’s the official intro video:

With the M, Waldorf Music returns to its classic Microwave and Microwave II tone generation.

The Waldorf M synthesizer is an eight-voice polyphonic, four-part multitimbral Wavetable Synthesizer.  Each voice features two wavetable oscillators, with independent wavetable-generating Classic Microwave 1 and Modern Microwave II/XT modes.


  • Two oscillator modes:
    • 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.
    • 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:
    • 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;
    • A stereo headphone output (with an associated Volume knob in addition to the topside Master Volume knob);
    • 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);
    • An SD Card slot (for updating M’s firmware, importing/saving sound patches, and importing/saving M-specific data, such as user wavetables); and
    • Kensington-compatible security lock slot.

The M Wavetable Synthesizer is available through Waldorf Music’s network of distributors at an RRP (Recommended Retail Price) of €1,879.00 EUR (including German tax).
