The Jomox ModBase 09 is a 19" Eurorack kick drum module that is CV/Gate-controllable, drum pad triggerable, storable with MIDI.

For regular modular use, analog routable CV inputs and an analog output are accessible via 3.5 mm jacks. The Gate can be configured as 0-5 V (0-15 V is accepted too), inversed or s-trigger.

Everything is storable and can be recalled via encoder klick from 100 presets. But for the analog feel of modular, eight potentiometers give you the fine and precise editing of the most important parameters without stepping through menus.

E-Drummers can create complete E-drum setups, because there is an internal Jomox analog connection bus with a fast digital link which can do a submix and an FX send mix from each module hooked up to the bus. With this system bus you won't need to use the audio outputs but instead you have a programmable bus system that can link to future master, sequencer and mixing or effects modules - which can take control over the single modules. This makes the whole modular setup recallable and storeable from a center module like a drum machine.

Also, to link the ModBase modules to our other products, they all have a Midi interface on the rear that can be wired within the rack case and being cascaded from one module to another. The menu selection is paged by two-colored LEDs for both sides of the menu. Two internal LFOs which both control the tuning of the kick drum VCO expand the sound spectrum once more.

All analog parameters are either storable and controllable via Midi. The MIDI notes control the pitch of the kick drum VCO.

Too, the modules are controllable via CV/Gate and via trigger pads for live drummers. With the trigger input, the threshold and velocity dependend dynamics can be adjusted.

Four routable CV inputs let all internal sound parameters (included LFOs and metallic noise) be controlled by CV sequencers. Every CV input provides an own programmable amount which can be negative too (i.e. subtracting the CV value from the internal value). The range goes from 0.5 V.


  • Tune: Varies the pitch envelope of the VCO
  • Pitch: Basses as low as 10 Hz reach up to 175 Hz
  • Decay Up to 2 sec
  • Harmonics: Enrichment of harmonics of the VCO - for the hardest kick drums on planet earth
  • Pulse: Change of the pure pulse part of the attack - gate time affects this parameter also
  • Noise: Change of the pure noise part of the attack - gate time affects this parameter also
  • Attack: Level of the mixing of Pulse and Attack
  • EQ: Filters the bass drum with a low pass filter - for soft and 808ish kick drums
  • Gate T: Varies the gate time from 0.1 to 16 ms
  • Compr: Compression of decaying envelope - for slim and clicky kicks and all the depth that is needed
  • MetNze: Metalized noise - a complex digital multitone pattern of 499 different combinations feeds the attack noise
  • CV1-CV4: can route the external 0-5 V CV signals to any of the above parameters including LFOs, negative amounts are also processed
  • LIN FM: is a true analog dedicated CV FM modulation input for the bass drum VCO, it only works linear-wise and does not offer musical semitones across the CV scale
  • LFO: The ModBase 09 has 2 LFOs that work on the pitch of the bass drum, the LFO always starts syncronous to the gate trigger - wave forms are: saw up, saw down, sine ±, triangle±, rectangle ± and portions of it
  • MIDI: Controllers are identical to the XBASE999/MBase11 - all parameters including LFOs can be remotely controlled by MIDI CCs
  • Bus Vol: Programmable level of the audio out signal mixed to the Jomox system bus on the rear. Will work with future master modules.
  • Bus Send: Serves as the programmable FX send to the Jomox system bus on the back side - it will work with future effects modules
