MicroZwerg

Launched in 2012 as MFB's pint-sized powerhouse, the MicroZwerg packs a full analog monosynth into a remarkably compact desktop shell—measuring just 190 x 130 x 50 mm—making it perfect for tight spaces or as a modular system starter.

At its heart are two voltage-controlled oscillators: VCO1 delivers triangle, sawtooth, square, and needle impulse waves with ring modulation, while VCO2 adds triangle, sawtooth, square, and noise, tunable up to one octave apart with sync via patch cable. Dual multimode filters (low-pass, high-pass, band-pass) each have dedicated audio inputs for external processing, fed by a single ADSR envelope and two LFOs offering four waveforms plus one-shot mode—LFO2 includes sample & hold and CV-modulatable speed for wild sweeps. Pre-wired signal path (VCOs to VCFs to VCA) gets you playing instantly, with 18 patch points, MIDI in (handling notes C1-C6, velocity, pitch/mod wheels), CV/gate, and USB for deeper experimentation using the shift button to toggle between sections.

Owners love its raw, aggressive tone and semi-modular flexibility for everything from leads to effects, though some note its tiny size demands careful knob-tweaking and a warm-up period for tuning stability.
