FMco brings a gritty, harmonically rich character into a streamlined 8HP format. It uses a modern 2-operator DSP implementation that prioritizes playability over menu diving, allowing you to sweep through FM indices and ratios with high-precision encoders. The module behaves as a versatile sound source that can shift from pure sine waves to aggressive, metallic clangorous tones by simply adjusting the Index and Ratio controls.

In a compact system, the FMco eliminates the need for external support modules. It features an integrated decay envelope hard-wired to the internal VCA and FM depth, meaning a single trigger pulse transforms the module into a percussive synth voice. For melodic applications, the built-in chord mode generates up to four voices with CV-controllable inversions, creating thick harmonic pads that benefit from the internal stereo widening effect. It fits perfectly as a lead voice or a source for complex FM percussion, offering stable digital tuning alongside raw, unpredictable modulation.
