When JoMoX released the MBase01 in 2008, they made a deliberate choice to build a bass drum synth that sounded distinctly different from their other percussion modules—not as a limitation, but as a feature. This was a dedicated kick drum specialist designed to sit alongside their other gear, filling a specific sonic niche with authority.
The MBase01 is a fully analog, single-voice bass drum synthesizer built around a voltage-controlled oscillator, analog envelope, and highpass filter. You shape the sound through a data wheel and five buttons that navigate 16 LED indicators, controlling parameters like tune intensity, decay length (up to two seconds), pulse and noise content, attack character, and EQ range. The decay envelope uses a true exponential curve rather than a compressed one, giving the sound a natural, organic tail. An onboard LFO modulates pitch and can sync to MIDI clock or retrigger on each hit, offering saw up, saw down, triangle, and rectangle waveforms. The module accepts external analog trigger inputs from any audio source—vinyl, drum pads, whatever—and responds with snappy, precise attacks. You get 64 ROM presets plus 10 user slots, full MIDI control over all parameters, and a single mono 1/4" output. The whole thing weighs just over half a kilogram and runs on a modest power supply.
The MBase01 earned respect in the community for delivering genuinely fat kicks that span the 808-to-909 character range without relying on samples. Users consistently praised its tweakability and the quality of its analog sound, though some noted the learning curve on the interface. The ability to extend decay and play pitch across three octaves in semitones means it doubles as a bass synth when you need it. For producers who wanted to move beyond sample libraries and dial in kicks that sit perfectly with their track's bass, this module became a reliable workhorse—and it remains sought after on the secondhand market years after discontinuation.
