Waldorf Microwave

The Waldorf Microwave (1989) is the rack synthesizer that carried PPG's wavetable lineage forward after PPG closed, pairing wavetable scanning with an analog filter.

Conceived as a streamlined, rack-mounted take on the Wave 2.3, it shipped new wavetables of its own, and the later DSP-based Microwave II and knob-laden XT turned wavetable choice into a hands-on performance control. Waldorf has kept the lineage going ever since — through the Blofeld to the modern Quantum and Iridium.
