ALM FMco VCO & Voice Eurorack Module

The FMco is a compact FM synthesis based VCO and voice. It features our own original 2-operator FM synthesis DSP implementation inspired by our ‘Akemie’ modules but tuned for more immediate use and a more modern sound.

It includes both manual and voltage control over FM Index, Ratio and a selection of classic operator waveforms for a wide pallete of FM sounds from a simple set of controls. A built-in decay envelope is routed to both FM depth and output level, allowing the FMco to function as a full synth voice when triggered.

The FMco also includes CV-controlled four-voice chords, an encoder-based tuning system for easy accurate pitch control, and a stereo-widened output, delivering a large amount of FM synthesis all in just 8HP.
