JOMOX MOD FM Analog + Digital Modular FM Synthesizer (Sneak Preview)

At Superbooth 2021, Jürgen Michaelis of Jomox is introducing the MOD FM, a modular analog/digital hybrid synthesizer with 4-operator FM tone generation.


  • 8-voice polyphony Euro format synthesizer
  • Digital oscillators with analog SSM filters
  • 2 LFOs per voice, which can also be used as VCOs, for six oscillators per voice total
  • Versatile internal modulation matrix plus external CV control
  • Four CV inputs control the FM components and 4 CV inputs control the pitch envelopes of each operator.
  • Eight audio outputs

Here are some audio demos via Lesides:

  1. reminder: for 1k euro you can get the modx that has fm synthesis w/64 voices *and* a 16-track pattern sequencer. the modx kills every synth out there, specs-, price-, and sound-wise.

    1. and it samples. cuckoo does a sampling tutorial on it.

      i sprung a little extra for pc4 (got in right before the price increase) and have been having great fun loading these up on it:

      each dx7 patch is 1 VAST block, so you can apparently go up to 32 part multitimbral, though I haven’t tried yet.

    2. The interface matters. Sure, they’re both FM synths but they are very very different animals. It’s like comparing a helicopter and a plane—they both do the one basic thing (flying) but they have very very different uses in practice.

  2. Too many engineers in this biz going down recursive rabbit holes and not enough product designers helping the engineers channel their skills into things that people actually want to buy.
