Waldorf M Microwave Inspired Wavetable Desktop Synth, Open Box [USED-MINT]

Waldorf M – Classic Wavetable Synthesis Reimagined

The Waldorf M is a modern homage to the iconic Microwave series, delivering authentic 1980s and 1990s wavetable synthesis with powerful new features for today’s musicians and sound designers. Combining true Curtis analog filters, multi-mode operation, and two independent LFOs per part, M gives you the unmistakable sound of vintage digital hardware—with enhanced control and workflow for studio or stage.

Key Features:

Classic & Modern Wavetable Engines

• Two selectable synthesis modes:

  • Microwave I (1989): 8-bit classic wavetable mode with true-to-original aliasing

  • Microwave II/XT (1997): expanded interpolation with modern clarity

• Over 96 original wavetables, with user import via SD card

True Analog Filter Section

• 24 dB/oct low-pass analog filter, based on the Curtis CEM 3320 chip

• Additional analog VCA stage for warm, punchy dynamics

• Independent ADSR envelope generators for both VCF and VCA

Multi-Timbral Operation

• 4-part multitimbrality, with independent settings per part

• Each part supports its own arpeggiator, effects, and modulation settings

• Flexible layering and splits via internal routing or MIDI control

Dual Oscillators + Sub

• Two wavetable oscillators per voice

• Each oscillator supports independent wave selection and modulation

• Optional pink and white noise, plus a dedicated sub oscillator

Extensive Modulation

• 2 LFOs per part, each with multiple waveforms and sync options

• Modulation Matrix with 4 user-assignable slots per part

• Support for complex routing between LFOs, envelopes, and MIDI controls

Specifications:

• Polyphony: Up to 16 voices, with dynamic voice allocation

• Multitimbrality: 4 parts

• Oscillators: 2 wavetable oscillators per voice, with noise and sub-oscillator

• Filters:

  • Analog 24 dB/oct low-pass filter (CEM 3320)

  • Analog VCA

• Envelopes: 2 ADSRs per part

• LFOs: 2 per part, with multiple waveforms and sync
