The Build & Sound of the Moog Grandmother

Description
Harkening back to the early years of analog synthesizers, Moog's Grandmother has the characteristic style of a vintage synthesizer from the past. But make no mistake; this all-analog semi–modular instrument is 100% ready for the future. With a design focused on pure synthesis, you'll appreciate the immediacy of just getting on and designing sounds. There are no presets, no recall, what you see is what you get, leading to a lifetime of creative sound exploration. Grandmother's sound engine, modulation engine and onboard spring reverb tank are 100% analog. There are no menus, nothing to get in your way of creating your own unique sounds.
Grandmother’s semi-modular design means you can start playing immediately without the need to manually patch and route any signals. But should you want dive deeper into creating more complex sounds, Grandmother features 41 individual patch points that will override the internal wiring, leading to expansion possibilities that are only limited by your imagination. Even if you’re only familiar with the basic building blocks of an analog synthesizer, the Grandmother welcomes an experimental approach that can turn into incredibly inspiring sounds. In addition, the 21 inputs, 16 outputs and a parallel-wired 4-jack mult, can be used to expand the Grandmother into a larger Eurorack ecosystem, or is the perfect patch point to integrate with Moog Mother-32 or DFAM semi-modular synthesizers.

All analog, start to finish
Grandmother has the essential tools you need to get started, with some added extras. There are two analog oscillators built-into Grandmother, each with selectable triangle, sawtooth, square and pulse waveforms, and a hard sync button capable of creating some very complex timbres. The analog LFO is capable of reaching audio rates, acting as a third oscillator that can develop into some really aggressive tones. Also onboard is a classic Moog Ladder filter with a range of 10Hz – 20kHz, a patchable 1-pole high-pass filter, and an analog ADSR envelope generator ready to sculpt your sound.

Diving deeper
The team at Moog thought of everything here. Knowing that most sound designers would use a spring reverb effect on a synth of this nature, they’ve gone ahead and added an onboard analog spring reverb tank capable of processing internal and external sounds. It’s a welcomed addition, with the ability to add some darker tones or tame any intense frequencies. Grandmother also features a built-in arpeggiator and an onboard sequencer that can store up to 3 sequences with up to 256 notes each. Add this to your Eurorack ecosystem and you’ll have full control over all of your modules.

Classic feel, current mood
Even though Grandmother is every bit retro in design, it features some modern-era additions that take this synth from a thing of the past into an instrument for the future. As for connectivity, the Grandmother has everything needed for today’s production environment including a 5-pin MIDI In/Out/Thru as well as MIDI over USB for instant integration with your host computer. There’s also both a 1/4” main output and a 1/4” external audio input that’s capable of taking in signals from guitars, drum machines and more. Grandmother can route these audio sources through its signal chain, imparting classic Moog character at every step along the way, including its spring reverb tank, and spit them back out again. Grandmother's 32-note premium Fatar keybed makes this a premium standalone synth but will also work perfectly as the front end to an existing modular system. No matter how you decide to use it, Grandmother will give you a lifetime of sound exploration.

Yes ma'am, may I have another?
I'll start by saying I play a number of different instruments. Mostly guitar, bass and drums. However, about 6 months ago, I decided that my long love for synthesis. I had done a tone of research, and had decided the best way to get I to it was to purchase a Behringer Model D. Man... that was a fun decision. That only peaked my curiosity though. I had seen a couple YouTube videos demoing the Grandmother and thought it was time to expand. I liked the fact that I could do some semi modular work with it as I got more advanced as well. Before I started, I downloaded a few patches from a site online, let the GM warm up for 15 minutes (like you should with any analog equipment), dialed in the settings from a patch and... I nearly called my boss to tell him I quit. I knew I'd make it as a professional musician. No excuses now with this thing in my grasp. I leave it chained to my wrist, like the atomic football that follows around the president. It's my secret weapon. I recorded a few tracks of some songs I was working on and shared them with family over Thanksgiving. Everyone in the room was asking how I'd made some of the synth sounds. I told them Grandmother was to blame. I now have 4 synths, but the Grandmother is my favorite. It's the favorite of my kids, who are learning about synthesis for the first time as well. I came home the other day and my 11 year old had the headphones on and was dancing and bobbing through some jingle he's put together using the sequencer. He loves it. I have a feeling I may need to get him his own. Ha! Get one, you won't regret it. The sounds are pure 90s. The spring reverb is a god send. The oscillators are incredible. You have to try really, really hard to make it sound bad. It's great for leads and bass. It can do it all. I've now seen them on stage here locally in Colorado 4 times. That should tell you something too... they're durable and travel well. This will be one of those synths that people look back on and think... I could have

Poor QC - Moog ain't what they used to be.
Sounds great but mine has had constant issues. Back at Moog now for a third repair in less than a year. Been buying Moog products for decades now, but this really is cheaply built. I only had mine in the studio, can't imagine gigging one of these junkers.

Awesome introduction to modular synthesis

This is a great synth, whether you're new to the world of synthesizers or have been playing for years. The keybed feels amazing and the layout is really intuitive. Super easy to dial in classic Moog bass and lead sounds and even get into some sound design. Would recommend this to anyone looking for the classic Moog vibe.
Can't say enough about this synth.

I didn't understand the hype on this synth when it was first released. I have about a dozen synths, all with the ability to store presets. It is a pretty important feature for me. I gave this guy a chance because people rave about the sound of the grandmother. I can't agree more. It's sounds amazing. As far as the lack of presets go, once you dive in it won't even matter. This thing sounds so good and invites you to explore in ways that keep you creative. Since I've pick this up most of my other gear has been collecting dust. The performance features on the sequencer are really nice. Especially the ability to edit the sequence in real time. If you don't have other eurorack gear I would definitely recommend picking up a few koma electroniks attenuater cables. It will expand your patching capabilities significantly. If you're on the edge about getting this just take the leap. You won't be sorry.
I love my grandmother

This is a truly amazing instrument, and I mean "instrument". Out of the box I was smitten in less than 60 seconds. 6 hours later, of non-stop knob twiddling and patching, I was in love. And, for those of you who have been there, you know almost nothing beats falling in love with an instrument.
Vintage Moog sound in a modern synth.

Used for analog lead and bass sounds as well as unique textures and semi-modular experiments. Great build quality and easy to use. Probably the best sounding mono synth on the market if you are after that vintage Moog sound.
Excellent synth!

I was just about to purchase one of these and you upped the price $150. Is that because of the case deal? Disappointed.

If I bought this (Moog Grandmother) on Thursday morning, 9/12 and had it shipped to the Guitar Center Oxford Valley location, is it possible that it would be there by Saturday, 9/14? Thank you
It depends on where it's shipping from. More than likely it won't since the shipping companies they use don't move anything on Saturday. Give us a call at 866-498-7882 and we can give you a for sure answer.submitted6 years ago
