Moog Spectravox Semi-Modular Analog Spectral Processor

The Moog Spectravox is a powerful semi-modular analog spectral processor that blends the worlds of synthesis, filtering, and vocoding into one flexible instrument. At its core is a 10-band filter bank that can take you from subtle tonal shaping to rich, animated modulation and experimental sound design.

With an onboard analog VCO, white noise generator, spectral shift controls, and envelope shaping, Spectravox makes it easy to create everything from lush drones and atmospheric sweeps to distinctive vocoder textures and deeply expressive sonic movement. Whether you're exploring standalone synthesis or integrating it into a larger modular setup, Spectravox delivers serious creative potential in a compact format.

Built for standalone use or Eurorack integration

Spectravox features a 36-point 3.5mm patchbay for extensive routing and seamless connection with Eurorack systems and other electronic instruments. Patch into the internal VCO, LFO, envelope generator, and more to unlock a wide range of sound-sculpting possibilities.

No modular rig? No problem. With its built-in sound sources, external program input, and included 12V DC power supply, Spectravox is fully capable as a standalone instrument straight out of the box.
