Oscillators & Wave Generators

3U Synthesizer Modules

This section contains modules for generating waveforms such as sine, triangle, or square waves or for reproducing more complex waveforms from memory table or from storage media. Modules that accept control voltage input for pitch control are based on a 1 Volt per octave standard. 

WSY104EU FM/PM Operator

The WSY-104 FM PM Operator module is a through-zero digital oscillator that has FM and PM modulation capability.


We produce electronic synthesizer modules in the two most popular formats, MU (Moog compatible 5U) and EU (Eurorack compatible 3U). A wide range of voltage controlled modules including oscillators, amplifiers, mixers, envelope generators, special effects units, wave generators, filters, power systems and cases allow users complete freedom to configure any desired electronic music instrument.


Grove Audio builds microphones, preamplifiers, equalizers, compressors and other professional audio equipment for performance and studio use. We build units in popular formats such as 19 inch rack mount and 500 series 3U modules. We can also produce custom designs on request. Contact us for a consultation.
