JoMoX Mod FM 8-Voice 4-Operator FM Synthesizer CABLE KIT

JoMoX Mod FM is a complete 8-voice FM synthesizer in eurorack format that promises enormously powerful sounds out of the box without forgoing the usual CV modulation options. Mod FM has 4 operators and 2 LFOs/VCOs per voice as well as 2 analog filters per voice and analog VCAs, which give Mod FM analog depth and warmth even though the FM engine is digital.

Each voice has its own CV/gate inputs and an individual output. There's a stereo mix output where the even and odd voices are distributed and where internal effects such as delay and reverb can be mixed in. In addition to the CV/gate control, Mod FM has MIDI in and out in 1/8" TRS Type A format and a USB-C port that also processes MIDI. This allows you to create great metallic-sounding FM sounds and crisp basses, but also soft and deep-sounding analog sounds without much modular effort. Mod FM also offers numerous external CV modulations, for example to modulate each operator individually or to control the FM envelopes.

Mod FM is also fully multitimbral, meaning each voice can have its own sound in Multi Mode, which is also saved as such in the Multi Set. Here we come to the biggest advantage of the hybrid approach: modular can become a trap with complex sounds and FM itself is inherently complex, making it difficult to get the same great sound from before again, so Mod FM's ability to save and recall presets certainly helps!

VCA

The VCA is a fast transistor VCA, which is important for snappy sounds and is featured in all JoMoX drum products. As a result, Mod FM can also be used as a rich sound source for techno drums and percussion of all kinds.

Metal noise

There is another sound source on the analog board: metal noise. This can be mixed into the filter independently from the FM synth digital sound engine and in turn offers an inexhaustible source of 'stark' sounds.

Effects

Mod FM also offers 2 effects – reverb and two delays – that work exclusively on the mix output. The delay can be beat-synchronized and offers the option of setting very short delay times in the millisecond range. This can be used to create very nice 'oil can' sounds and flanging effects.
