Moog Mother-32 Semi-Modular Analog Synthesizer

Put that classic Moog analog synth sound on your desktop. This "Mother" gives you a Moog Ladder Filter, 32-step sequencer, 32 patch points, MIDI in and more.

Moog Mother-32 is the first semi-modular tabletop and Eurorack synthesizer from Moog. The Mother-32 adds raw analog sound, sequencing and extensive interconnectivity to any electronic or modular ecosystem and was meticulously designed to provide musicians with a diverse array of creative tools to inspire new music, unique sound and endless sonic exploration. It comes secured in a rugged extruded aluminum skiff with wood sides and features a modular patch bay with 32 patch-points for extended synthesis complexity and an assignable CV jack with 16 assignable sources.

The Mother 32 is the ultimate gateway synth. It’s not the easiest thing to use (especially if you are new to synthesis) but with the tiniest bit of effort you can get some very classic mono synth sounds without touching the patch bay. Then, once you feel like you have mastered the basic controls, the world completely opens up with the patch bay. People that say “everything sounds samey” are lacking in creativity. Sure you only have square and triangle LFO waveshapes, but patch the envelope generator into the LFO rate (with triangle wave selected) and you have a shark fin! Sure there is only one oscillator, but patch the other wave into the external audio input and blend those shapes baby. Or do that with any other audio! The secret weapon is the assignable jack....have fun with that one! And the sequencer too... don’t get me started. It’s a blast!
