After releasing a few teaser images, Waldorf Music today announced Protein, a compact 8-voice polyphonic wavetable synthesizer that combines recreated Microwave 1 ASIC oscillators with features inherited from the Iridium line, including an arpeggiator, step sequencer, chord mode and multiple effects.
Waldorf pitches Protein as a return to the origins of its early wavetable instruments but in a more contemporary format.
The front panel has been designed for what Waldorf describes as immediate, hands-on control with the aim of building complex sounds quickly from simple building blocks, while a deeper sound design architecture sits behind the main controls for more detailed editing.
Layered engine and modulation
Protein has 8 voices that can be arranged as up to 4 independent layers. These layers can be used for stacked patches, round robin setups or split by MIDI channels for multitimbral use. A Load Layer function lets you recombine layers from the preset library, making it possible to create new sounds by mixing elements of existing patches.
The instrument ships with more than 150 factory presets and space for up to 250 user presets. Using the 4-layer structure, you can combine different preset layers to build new composite sounds without starting from scratch.
Each layer has its own eight-slot modulation matrix, providing multiple modulation routings for shaping the sound. Protein also supports polyphonic aftertouch as a modulation source, allowing expressive control when paired with a suitable controller. A dedicated Flavour knob adds what Waldorf describes as organic behaviour, from subtle micro-fluctuations to more noticeable disturbances to keep the sound from feeling static.

Classic Microwave character
At the core of Protein are recreated Microwave 1 ASIC oscillators. Waldorf leant into the original gritty, 8-bit quantised and aliased character, running at the same 250 kHz sample rate as the original hardware. The intention is to deliver the vintage digital tone, including its characteristic artifacts in the lower and higher octaves, inside the new compact chassis.
