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 patchbay 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 patchbay 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 patchbay. 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.

Moog Mother 32

Excellent mono synth,fun to use with Moog DFAM & Subharmonicon. It compliments both as your lead or rhythm synth. Excellent sequencer as well. Extremely well made with high quality parts. I highly recommend picking one up.

Moog Mother-32

My name is Gary and I'm a Moogaholic.

I know this even though I own only three Moog synths (a wood-box Theremin, a Werkstatt, and now a Mother-32) and I'm essentially in Moog kindergarten. What I know about oscillators and modulators I learned as an undergrad in music school on a weird suitcase Arp that must have been designed for college classrooms. But I didn't continue with it. My addiction was initially kicked in with software synths – Serum, Diva, and Vital are faves. And then I bought a Dreadbox Typhon and the angels sang. The Typhon is a trip - so much in that little box.

But I still felt at sea with what I was doing. I wanted to get closer to imagining a sound and knowing how to build it. So I enrolled in subtractive synthesis 101: the Werkstatt. And all of those software synths started making more sense. But the sound! Rayon or cotton? Cotton, thank you very much. I'm still intimidated by having to know what's being un-normalled when I plug in a cable. I survey my dials with more doubt than confidence that I will comprehend why the sound I hear is happening. And then I build a sound and it does what I thought it would do. And it's a beautiful thing. Can I recreate it the next day? Not always. But I'm in love with this journey – unapologetic aging hippie here, eager after 69 turns around the sun to keep expanding my sonic world.

So, this is supposed to be about the Mother-32.

I'm about 40 pages into 'Patch and Tweak with Moog' and, of course, it's telling me that I need more Moog in my life. I don't disagree. But I'm going to chill with the Mother for a while. I'm not a beat maker. And I resist the loop vortex. But, jeez, when you get a good groove going and move it around with the LFO and the EG, it's intoxicating and a rabbit hole. The Mother-32 is like middle school. I think I'm getting a zit. I'm way too old for zits. But I'm not too old for Lincoln Logs!

Man, What a Perfect Introduction to Modular Synthesis

I've had my Mother-32 for a bit less than 3 weeks and am so glad I finally decided to pick one up. As someone who has been interested in modular but didn't really know where to start, this has been a great introduction. Moog's classic Pulse Width and Filter are the stars of the show for me but I'm having a blast exploring new patch ideas every time I sit down with it. Where I'd probably dock stars for a lack of features on any other product, I'm having a lot of fun creating workarounds and solving problems with my Mother-32 that I can't even say the feature limitations are a bad thing as they actively encourage exploration. If you want to dip your toe into the world of modular, pick this bad boy up.

What Do Our In-house Gear Experts Think?

Andy Miller

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.

Want real Moog sound? Take it from the die-hard analog synth masters here at Sweetwater: buy a Moog. It doesn't matter which one; their synths start at top quality and only go up from there. Sweetwater's relationship with Moog goes way back, and some of us fondly remember the last time Bob himself came to visit. Over the years, we've had the honor of watching Moog grow and evolve, and with synthesis experts like Daniel Fisher on staff, we're still one of the first companies to catch wind of new Moog products - they never fail to impress! Whether it's a classic reissue, a breakthrough new keyboard, or even a cool effects pedal, you can be sure anything you get from Moog will make you happy, and we'd love to tell you all about it.
