Semi-modular Moog for Eurorack

Moog joins the Eurorack revolution with the semi-modular Mother-32 monosynth. This distinctly vintage-voiced, raw, powerful synthesizer boasts switchable lowpass and highpass Moog ladder filters (20Hz-20kHz), a voltage-controlled 32-step sequencer for self-contained programming, a MIDI input for external control and MIDI to CV conversion, and a 32-point 3.5mm patch bay for interconnectivity and extended synthesis capabilities. For those of us at Sweetwater who've jumped into this modern modular synth format, the Mother-32 is truly exciting news. And if you're looking to get into the Eurorack synth platform, you couldn't ask for a better starting point.

Powerful analog sound for your desktop

The semi-modular Mother-32 serves up the iconic Moog analog sound, yet it's also conveniently modern. Its massive analog tone spans the range from fat and wooly to sharp and metallic. You can route most of the Mother-32's modulation sources via mini toggle switches, giving you access to impressive sound-design power. You'll be able to generate earth-shaking bass, screaming leads, and atmospheric effects without ever touching a patch cable. And thanks to the 32-point patch bay onboard the Mother-32, you can easily connect other Eurorack modules to create a vastly complex and extremely powerful synthesizer. The MIDI to CV converter and 5-pin MIDI input let you integrate the rest of your synth gear. Want to build a bigger synth rig? Grab a 2-tier or 3-tier rack kit for your Mother-32 (available here at Sweetwater), toss in a chassis or two, and load them up with other great Eurorack modules from Tiptop Audio, Pittsburgh Modular, Studio Electronics, and many others.

Classic analog synth architecture

The Mother-32's oscillator section offers saw and pulse wave shapes, plus control over pulse width. There's a noise generator too, and the filter resonance can reach self-oscillation as well, allowing you to use that as an oscillator with a simple patch. Use the LFO to modulate the Mother-32's VCO and VCF, or other Eurorack modules via the patch bay. The LFO offers square and triangle wave shapes and can reach audio rates for a wide range of creative effects. Use the AD(SR) envelope's Attack and Decay controls to quickly shape your sounds. Sustain can be engaged with a switch, at which point the Decay control becomes your Release control. You can generate everything from percussive hits and pluck sounds to sustained leads and evolving soundscapes. For sheer fatness, it's hard to beat Moog's classic ladder filter design. On the Mother-32 you can choose from lowpass and highpass modes, and the filter can be modulated via the LFO, envelope, or via external CV control.

Voltage-controlled 32-step sequencer

Two sequence modes make it easy to lay down patterns with the Mother-32. KB mode allows you to play notes in directly from the keyboard panel, while Step mode lets you program in notes manually. You can combine the two modes to play and edit patterns with incredible detail. Each step in your sequence has variable gate length, and with ties, glide, and accent control, you'll be able to achieve highly animated sequences (64 custom sequences can be created and saved). You can also add multi-note ratchets to individual steps to create cool stutter effects. And while the sequencer is running, temporarily mute playback, add accents, ratchet the sequence, and transpose the sequence for creative live performance potential.

I addicted for this Moog! Thank you Sweetwater! :)

Greatly engineered and Fun to operate.

It is Moog right? But besides that this is a well made and engineered synthesizer. Great and endless richness of sounds. It was tough to desire which Synth/Modular to finally choose from the array of incredible assortment of fantastic choices for Sound-Synthesis creation today. The very detailed and well produced instructional and teaching videos that Sweetwater kindly offers to costumers is very valuable and a great help to make a purchase desition. Thank you.

Very powerful

endless hours of hands on discovery And it sounds great Thanks For everything

My first step into Eurorack

I've always wanted a Moog synthesizer. I had a micro moog back in the day, but it was half broken, and I'm a very Logic-centric musician and producer. I love soft synths. And I love to edit, quantize, and otherwise perfect Erica my MIDI tracks. I wasn't in any way unhappy with the sounds I get from Arturia or Native Instruments, or Logic's own synths, but honestly thought modular look so cool, i want to build one. Well, the second I plugged this little puppy in, I knew what i had been missing. It sounds great! I used it on a recording that night, and it has grown into a pretty awesome little Eurorack synth, with 8 modules and growing. The Mother 32 is a great starting point, because its i/O and MIDI connections, and it all just works, right out of the box. And you will always want to have that amazing Moog filter in your arsenal.

Great Introduction to Modular!

This little unit completely changed the way I think about synthesis. It's compact, well designed, and invites you to noodle to your hearts content. The oscillator is pretty basic, but you can do so much with this little guy, and the sequencer is absolutely brilliant. So great, I now own two of them, and the possibilities really opened further!

I got the chance to check out the Moog Mother-32s wired together in their rack with an Elektron rytm8, and it was extremely fun. I sequenced up a killer bass riff and then used the other two, all without using a single patch cable! When I played with the CV patch bay, it was like stepping into a new universe. I couldn't guess what any knob might do, which got me to try things I'd never heard before and fully appreciate modular synthesis.
