Doepfer - A-137-1 Wave Multiplier (Silver)

A well-engineered and highly flexible wave multiplier module, the Doepfer A-137-1 is designed to dynamically shape and fold waveforms—perfect for adding rich harmonics and complex motion to both audio and CV sources.

The module excels at wave folding and distortion, making simple waveforms (like sine or triangle waves) sound much more complex and animated. The A-137-1 provides four key parameters—Multiplication, Folding Level, Symmetry, and DC Offset—all of which can be modulated via CV for dynamic sonic movement. The input level can be manually adjusted to match signal strength, while CV control over the rest of the parameters opens the door to wild modulation possibilities.

Whether you're processing audio for metallic textures or warping CV signals into unpredictable modulation sources, the A-137-1 is a versatile tool for sound designers and experimental patchers alike.
