Jomox ModFM Eurorack Synth – 8-voice polyphonic Eurorack FM synthesizer with 4 operators per voice, modulation matrix, 2 LFOs/VCOs per voice, analog filters and VCAs. It offers advanced sound design, flexible CV/MIDI control, and multi-timbral modes. On board, there is a rich effects section with reverb and dual delay, overtone scaling, multi-mode filters, and extensive performance functions.
Jomox ModFM Eurorack Synth is an environment for sound creation designed for exploration. Each voice can operate with 4 sine operators interconnected via matrix, from simple FM tones to complex hybrid sounds with analog warmth. Flexible routing with individual voice outputs, stereo mix, and external CV inputs enables a wide range of configurations – including new features for the Jomox ecosystem.
Modulation is deeply integrated: full matrix with 26 algorithms, LFOs switchable to VCO mode with 64 waveforms, ADSR envelopes for pitch and volume. Control via MIDI CC, USB, or CV/Gate for external modulation. The module offers multi-mode with up to 8 single presets, voice allocation, and advanced triggering conditions.
