    Moog Music Slim Phatty Review - Analog Technology Democratized

    Five years after having introduced the Little Phatty, Moog decided to launch the compact synth in module version. Did the Slim Phatty succeed in making the famous Moog sound available to anyone?

sw80's review"the best analog, portable and low priced"

Moog Music SlimPhatty
The Moog Slim Phatty is under priced, it is worth way more than what it is sold for. It is a tabletop synth that has two oscillators, an arp, envelope generators , MIDI and USB ins and outs. The screen on this unit is very simple and basic. It is not color and it is not touch screen, but it still gets the job done with out a problem. If you want to add some really good analog sounds to your current set up and music then this is the way to go. Its a lot better then using any analog synth VST. This is the real deal with 100 plus different presets and the ability to tweak and change the parameters of each one of those presets you will have endless sounds at your finger tips.


Using it is simple if you have an understand on how to work with analog synths. If you are new to analog synths then it could take some time understanding how sounds are created. But once you learn you will be able to create almost any sound your mind can dream up. It will really open up your possibilities to new heights once you learn to work with analog synths. I recommend this to someone who is new because it is a great foundation to learn how these synths work.


This is one of the most portable analog synths that I have ever used or seen with my own eyes. It weighs almost 6 pounds and it is only 17 inches wide. You can pretty much put this in your back pack and take it with you anywhere.


You can get a really “phat” sound when working with the Slim Phatty. All of the presets are pretty good, but once you start to jazz them up a bit with some effects and your own flavor your will love what comes out of it. There is also a headphone plug so you don’t have to play the sounds out loud when your are just messing around. It does have MIDI out and in /thru. I used it with a MIDI keyboard to play the sounds and then had all of it going through my MIDI rack to sync with Cubase. Then when I wanted to actually record the sounds coming out of the Phatty I just recorded them directly to Cubase. It really is simple to use this unit, it is the best portable analog synth out. It is also really affordable.

songboy's review"The ultimate sound for a remarkable price"

Moog Music SlimPhatty
This synth is a rackmount only unit. I use a Axiom 61 key with it and it responds beautifully. There are a fair amount of presets that give a great representation of what this synth can do. Styles? well, being that it is an analog synth featuring almost everything you would expect on a portable synth, I think it would fit in every style that you want to hear a thick, glorious analog sound. As for editing, absolutely. There are plenty of knobs and buttons to tweak till your heart's content. As for controllers, this synth is capable of receiving every standard control message for pitch, modulation, sustain, arpeggiator on/off, etc...... There are a few connections on this synth including 1/4" output and input (to process audio through certain parameters like the Super Sweet Moog Filter) and a headphone output. You also get 4 CV inputs including Volume, Filter, Pitch and Keyboard Gate all of which can be controlled by a foot controller, other moog gear (pedals/synths) and with the right equipment (cv output converter) even software from a laptop (i.e. ableton). You can in fact store presets on your computer which is very nice. You can also download and update the OS when applicable and also change the "tuning" of the unit to get far out scales (download at Moog Music).
This is a Mono synth, so no polyphony, just a single sound. There are two oscillators however so you can get some "harmony" or "disharmony" by adjusting the pitch of the second oscillator.


Yes, the sounds are very easy to edit as all (actually most, there are a few hidden features) the knobs and buttons sit right in front of you. If you are familiar with how a synthesizer fundamentally works, this synth will be a breeze. I would even recommend this to folks as a solid introductory synth (paired with a good synth tutorial or book) and you will never want to stop playing with this unit. The manual is clear and well written. I recommend reading it thoroughly inorder to exploit this synth to its full potential.


These are 100% analog signal path sounds so they don't get any more realistic as that. Touch sensitivity, aftertouch and the responsiveness of the knobs and buttons are spot on and what you would expect from the folks at Moog. There are only a few "effects" on the unit, such as the Moog 12 stage filter and the Arpeggiator. But those two effects alone are worth the price tag. I love every single sound that comes out of this unit. I have been using software emulations of moog gear for years and always loved it, but after using the "real deal" I imagine those synths will be collection virtual dust now. I especially love the basses, this thing gets low and dirty!!! No a/d d/a convertors in this unit.


What I like most about this unit is tied between three things: the great affordable price ($800), the absolutely amazing sounds and usability, and the fact that it is small enough to tuck under my arm. The only bummer about this synth is there is no "Noise" option as a waveform option. This reduces the amount of sound possibilites but in the end, you get a ton to work with for how little you pay. The only synths that come close in price and quality I know of are the David Smith synths mophro and tetra (i think that's their names) but I still find Moog blows David Smith out of the water when it comes to tone quality. I have used a fair amount of synths in my life and I have always been drawn to Moog more than any other manufacturer. I spent some time with a Voyager a few years ago and lamented that I wouldn't be able to afford one for awhile. I still can't afford the Voyager I want (about $5000 for the XL) but I now have a Moog synth that gives me the tone I need for a fraction of the price.
Yes, I urge anyone interested in analog synthesis to pick this puppy up.

esl's review (This content has been automatically translated from French)" It's a Moog, but ..."

Moog Music SlimPhatty
It is a mono classical architecture, very simple modulation matrix, not to say simplistic.


The front is good, excellent control and a touchdown fine. For cons, the menu navigation is very average. Damage.


No doubt, this is a Moog. Filter, envelopes, oscilloscope, are very very good. Super can choose the filter slope, it opens up more possibilities. There is really only one thing that will not is the linking feature to play polyphony. Not count on it (see below).


A very good mono sound with Moog and for a reasonable price, it's nice. Well, it is very simple, okay. As against, poly chain function is too unstable to be actually used. Already the SLIM does not take good agreement. Not serious in mono, but with the addition of poly poly chain must be reset every 30 minutes, it's not done at all. I had 4. I sold everything.

Benjaminbou's review (This content has been automatically translated from French)"Fine"

Moog Music SlimPhatty
What type of keyboard (synth, piano ...)? How many octaves?

No keyboard is a rack. I have not counted the number of octaves, but I've never felt limited at this level. Note nevertheless that this is a true analog, and that it takes time to s "grant". This is quite strange, it's like a musician who needs to make its range before playing his song. At the beginning, it is wrong in too serious and treble notes, one has the feeling of pushing. After a quarter of an hour max, everything is niquel, and overall even 5min everything is good. According to Moog, however, the beast is not 100% after 45min heating, and it is true that the more he runs, the better it sounds. It really looks like this machine is alive!

How sounds, effects? What styles? Are they edited?

There are presets, which is average, although the overall sound of the machine is so good that even the poor presets are nice (where the presets of a Nord Lead, for example, are simply disgusting and useless) . But we must hack to understand why we spent so much money. Style: 100% electronic, all styles. It can range from techno to accousmatique music to pop, everything sounds with class. Everything is editable despite the low number of knobs. In this regard, it is very well done and it is rare to feel frustrated by the low number. The only annoying thing is the filter cutoff and reso on the same knob, but honestly it is not so disturbing as I thought. To be clear on this point, Moog has developed a system that I have not seen anywhere else, which seems to detect the speed at which you turn a knob to join as soon as the desired position. It's pretty crazy because no one asks the question, the value moves intuitively to where we wanted it without having to torture the knob, even if we want to go from 0 to max. The machine seems sensitive to the slightest gesture and understand what you want it to do.

What controllers (pitch, modulation, sustain ...)?

No pitch bend and modulation because it is a rack. I think it's a shame because I have a beautiful Yamaha piano with heavy touch can become a MIID controller but does not include pitch bend and modulation wheel. It is unfortunately the case with all the racks. So you need a midi keyboard with pitch bend and modulation. Note that you can still use the big knob left (section "modulation") as a modulation wheel if you long press the "Amount" button. I thought it was gadget and ultimately, in my setup, I use this feature all the time. It is also useful when you do play the synth loops by a sequencer and you do not connect a keyboard.

What connection (Audio, MIDI pedals ...)?

There are four control voltage inputs (analog control) for pitch, volume, filter and KB gate. There are twelve o'clock traditional connectors, but you can also connect the midi in / out via a USB cable. Notable thing: there is an audio in. We can therefore insert any audio source in the synth, which will be processed by the filter and the envelope along with the oscillators. For cons, the LFO does not interacts with the audio input. This audio in function is very nice on paper (especially since Moog sells in the manual as an opportunity to make polyphonic) but in the end is not very convincing, I think. Do not expect to have a Moogerfooger MF-101 on hand through an audio in the filter, for example. Its only real use is when you spend a Moogerfooger MF-107, which adds an oscillator (oscillator and excellent) the Slim Phatty.

Via a Mac utility / PC?

There is a VST that I find deeply unnecessary and very expensive while the synth is already expensive. Learn a little about how MIDI works will help you avoid unnecessary costs for this synth as for many others. It is not very complicated and the Slim Phatty's never been a problem for me to be controlled by Cubase or Live. Just read the manual to find out which controller corresponds to which function, and everything works without the need of official VST. Still, I find dare from Moog to pay so much a VST that serves as midi interface and thus produces no sound. Heureusment we can do without.

What polyphony?

This synth is monophonic.


The general configuration is it simple?

Very simple, no-brainer for. Little knobs but it is as if there was a by function. Each knob controls several parameters that you select with the buttons. Nothing more complex: there are a few menus to manage various options. The screen is tiny but perfectly adequate, everything is well thought out. We never thought that this small often with standalone machines: "ah, if only we could do it on his PC ...". Here, everything is intuitive and very little time.

The manual is clear and sufficient?

I ordered from Thomann and I got the manual in German! ... I downloaded it in English, it is clear, no complaints.

Editing sounds and effects is it easy?

As simple as if it was 1potard/1fonction. The reaction of the knobs when a parameter we pass to another is very well done, so that you never deal with jumps from one value to another, or things like that.


The sounds they suit your style of music?

This is what I was looking for by going to analog. I love the synth sounds that can be heard on an album as Autechre Oversteps, and I love the German krautrock 70s. I found all these sounds on the Slim Phatty. To be quite frank, I discovered the Moog MF-101, which is a marvel, and I have since bought the MF-103 and MF-107. A small fortune all this, of course, but what made ... The Slim Phatty and the Moogerfoogers give me the impression that I do not need to buy anything for twenty years, so the possibilities are endless!

The effects are they effective and responsive?

There are no effects, the sound is raw.

What are the sounds you prefer, you hate? ...

My only regret is the tendency of sounds to be too bold. I know this is the main argument of the brand, but it also has the reputation of soft and organic sounds, "mellow" would say in English, and this is what I want. The filter Slim Phatty is quite aggressive and the overall sound quickly turns into a kind of saturation. This is excellent and very musical, but I prefer the sweet sounds. That said, with a little patience, I finally get sounds so subtle and round that I had tears in my eyes ... All this to say that perhaps, in the first half hour, you will have the feeling of having really cracked the wallet. But after a bit of taming, you will realize that this purchase was for life, or something like that. It's simple, at the beginning I had the feeling I was mistaken in my choice, and now I could not do without. Sometimes I spend hours fiddling with the beast, stunned by the sounds that seem to come from another dimension.

Are they realistic?

No, it's a synth.

The expression is good? (Reaction velocity, aftertouch)?

Very, very sensitive. If you had only VST far, you will not see a knob in the same way. Every millimeter counts. In terms of playing the keyboard via MIDI, everything goes well. There is no after touch, however.


How long have you use it?

4-5 months.

Have you tried many other models before buying it?

This is my first synth. At first I was skeptical, I thought the defenders of the analog exaggerated the difference in sound between digital and analog. I was wrong: it is * really * different. It does not mean that digital is bad, however. These are just two different things. Analog sound is difficult to describe, but the first impression it gives me is to be a little magic. It appears out of nowhere, and it is smooth, perfect, really captivating. I'm not going to rant for 50 pages, you just have listened to true (not a Youtube video ...) to understand the difference, which is really a difference and not a little delirious music geeks, I ensures (after much skeptical!)

In short, this is my first real analog. That said, before I tested the Nord Rack 2X, analog synth emulation. The two are not really comparable. I love just as much as the other. My Nord Rack will never give me to tears with a single note, but my Slim Phatty never give me cloths, 20-voice polyphony and other essentials for the things that I am keyboardist. For those who are wondering, I can confirm that the analog emulation Clavia is stirring: it is the only digital synth approach that sound. But I can also confirm that the difference is a real obvious. And that, having tested the Slim Phatty and 3 Moogerfoogers the Moog sound does not seem that expensive when you do not have the thing in your hands. Once the device at home, we do not regret a single euro, and I have never yet had a bad surprise at this level with this brand.

What is the particular feature you like best and least?

It costs € 35 for the racking ... More importantly, you should know that besides the Yellow Cable, just a little stronger jack does not happen if you put the Slim Phatty on your desktop, because the connector is facing down! It is very poorly thought out. It seems that the device has been designed for the rack ... this is not a fault, but still need to provide the means to racker directly, rather than the rack kit sold separately at 30 €. Thereupon, as the official VST or wooden decorations (100 €! ...), It looks like Moog hope eventually offset the nice price of the synth for its quality.

How would you rate the quality / price?

Good. It's expensive, yes ... But it's worth it, and it seems solid (although the knobs appear to be more fragile than those of Moogerfoogers, whose finish is just perfect). We can not say it's cheap, but for this quality, it is not at all a arnque, far from it. This may be the only product of the brand that is not Abusement expensive. I love Moogerfoogers (you are you probably realize ...), but their price is despite abusive nothing. Here, I find it quite in line with the machine. This is not particularly a "good plan", but it is not a scam either.

With experience, you do again this choice?

Without hesitation.

€ 777 at Thomann, it requires a lot of thinking ... But if you want a monophonic analog, then you're pretty sure of keeping this one for decades!

Tke's review (This content has been automatically translated from French)" Ease of access to his moog"

Moog Music SlimPhatty
Analog synthesizer without a keyboard, two oscillators, modulation, filter and envelope

I enter my data via Ableton Live, simple as putting a key in a lock


I've had 4 hours, it's very simple to who has used analog synthesizers, everything is very well thought out despite the presence of a single knob for several parameters.


Sounds Moog Direct, this is what I wanted. We can get good bass, leads aggressive, fx ... In just 4 hours, I could see that this instrument seems pretty versatile on the different sounds possible. I compose techno, and it checks out with what I have in my head.

I tested the same sequence with a plug-in that wants to be a clone of the Moog ... well and the plug can go to bed (well my computer is not an arrow either)


I said earlier, these are my first steps with this synth. it was long since Moog tickled me, and with this rack configuration, for which I am not a keyboardist, it is the foot.
Everything is under control, it sounds big but it does not break the ears (no nasty surprises by turning a knob), and for that price, well I remade this choice every day ...

Gritch's review (This content has been automatically translated from French)" The revelation"

Moog Music SlimPhatty
Features simple, albeit with some good surprises in rummaging through the submenus.

Unfortunately monophonic, but that these are the joys of analog.

Fully configurable through your sequencer, making it just as much practice as a VST beast.


Ergonomics very pleasant. Knob and buttons of very good quality, super nice color that lights up like a Christmas tree, one LED that lights up sythme LFO, ouahh ...

Negative: too bad the cutoff and resonance is the same button. It can be solved easily with a controller but good.


It comes to what makes us all buy the slim. THE SOUND. It has to been a revelation for me. I have for years used emulations expensive, and I thought that all owners of older machines were expensive as snobs thirties not knowing what to do with their corn.

Well I put the finger in the eye very deep. Prepare to be faced with a real instrument, the equal of a cello or a tuba. The sound takes you bide with unstoppable groove, treble you caress, you touch a knob and they become angry without being aggressive. Versatile and deep, this synth is a marvel of nature (human)

Since I try to touch as little as possible to my VST.

One thing: providing a very good sound card if you want to enjoy the difference. Coming out directly on a wall, it's magic, but when you scan you lose the signal already part of its fascination, and its lead vst face.
So I am looking for a fireface400 (yeah it's been expensive, but after such a revelation, there are even more ...)


Here is a turning point. Welcome to my world of analog, a world where you stay gaga before a note with two oscillators, but the difficulties and constraints are doubled or tripled.

See for yourself! I did not hesitate one second

SeanT's review (This content has been automatically translated from French)" Small but very fat!"

Moog Music SlimPhatty
The moog Slimphatty is the expander version of moog littlephatty! It has a line out and headphone, an audio IN and CV input.
This synthesizer is no exception to the rule moog, and it is not polyphonic (I never understood the reason too).


In use, the moog is perfect. It is ergonomic, the knob is very nice and very reactive.
The bone is very well implemented. It is easy to navigate menus, even if it is long enough a force! (Fortunately there is the VST rekon, or modules max msp for Ableton Live for easy navigation)

It is also easily transportable thanks to its light weight! (Please note it may be a bit tight for a bag Moog theremin)


The sound is fat! This is the moog! I could compare it with the software (Minimoog). There is not to say, I begin to understand the advantage of a hardware synth: This is dirty, this is down!
Also, the LFO is very clean (and this surprised me quite well especially when you approach 500Hz) and modulations. We can get sounds "FM" strong character and with character!

I regret that the oscillator is not as brilliant as I'd imagined (being used to the software). However, with the overload, it is possible to add harmonics when the filter is at an end. The bass sounds are excellent. For electronic music, it's a pleasure!

Each bone is added functions, such as: the velocity on the filter and volume. (Although as it is a bit light!). This opens up new possibility of modulation!


I have been using it 1 month, and I am delighted to have acquired, and finally a dream come true.

What I like most: The American side! It's bold, heavy and dirty, but both very sharp and clear. The sonic possibilities are immense. Thanks to the self-oscillation of the filter and modulation "filter env" on the pitch, can be obtained quite easily kick drums and high quality!

The least: The lack of modulation and oscillator, and that's it. the rest is perfect!

The price / quality ratio is good experience and I would do with this choice

orteil's review (This content has been automatically translated from French)

Moog Music SlimPhatty
I took it out of the box a few days ago. But I already have a first idea of the beast.
All it takes very little space, the interface is really well thought out.
I was looking for a Monaural analog, small size (little space available), 2 osc, noon, tap tempo, the disto, quality filters, a ARPEGIO, and it has everything!


Everything is pretty simple when you know an editing sounds from a synthesizer.
There's no 36-page menu (a priori).
I have not had time to do too much around, but it made me look simple.
For now I have not opened the manual more than 30 seconds. I just doubt on the button supposed to mute the master audio but not the headset (it does not work) and the level of the LFO button supposed to switch to ModWheel if we stay above support, but for me I have the impression that the opposite, he is ModWheel default. In short, to see ... nothing too serious.


For the moment, not disappointed at all!
The sound is huge. Filters hyper expressive and "scratch" just as I like. My thing is not the synth solos as can be seen on most of Moog demos on the net.
Like the big analog bass, the vengeful and Lead ARPEGIO that make you move the butt, this kind of stuff. And I'm ready!!

It is a monophonic, so no big slicks here. I have another gear for that!
No effect either, so the sound is dry, in your face. For now


(!!!!!!!! I will be a different opinion later) is an excellent purchase.
I can only compare a few synths (Virus KC, Roland SH32) or Plugz and there is no photo, it sounds.

The virus is very different in terms of its two very separate worlds, but the result is there for big bass and leads, the sound is big, wide, supplied, and bold (there is many other adjective to put behind ...). I file the impression that it could be mixed as it is in one piece (no need to boost it or compress it ...). Actually I am facing an analog after hearing a Mopho and Monotron (two good synths too). There is still magic in the analog.

The only problem, knobs, to my taste, it Bécanne limit for that price. it's the first thing I saw on leaving the SP board, the buttons move slightly, are not well attached to the knob, it makes me a little afraid for the future.
€ 749 keyboard in space, paid 3 times, I think I made a deal to end!
I highly recommend!

nucléo's review (This content has been automatically translated from French)" THE FAT!"

Moog Music SlimPhatty
It's like little phatty I think at the sound module, no keyboard, rotary bend and modulation wheel.
All technical data on the Moog website. Noon are the connections made by pins or usb.
With some keyboards master, I noticed that, once connected to the Moog, it must first turn on the Moog keyboard if not before, no sound. Big mystery!


Pretty simple to understand if one has already modulate analog synth sounds with tilt, filter, modulation envelope.

English manual. There is an extra for a brochure that summarizes the functions of the dashboard.
I still can not run the Audio IN, although I plug my bass on it. The manual is not very explicit about this. Stay tuned.

99 sounds, no bank "user", hence the original sounds lost sounds if you save your settings, too bad there are not two briefs: Factory Sound / Sound users. Restore factory setting possible.
Possible to buy an accessory, wood trim or rack mounting.


Its huge for my taste, but I have not handled before Moog, at home with my system.
The sound is very thick, especially for bass sounds (normal you might say). Moog grain is there, it won.
I love the arpeggiator.
Possibility of editing sounds already huge with both Osc and functions / settings that delivers the corny.


I have to acquire the Moog sound hardware with a small budget. The price and very attractive in view of the sound and possibilities of the machine. Plus it allows me to have real Moog sound in concert, easily scalable, in addition to my usual keyboard without lugging a second MIDI keyboard. Provided you have a MIDI keyboard recess, with a former Rhodes, it is useless!
For those who have not yet Moog's first investment really interesting and honest I think. Big thank you to the brand for this "social moog.
For those who have too much to bear Moog, it will be the favorites of your back! (Very light, can juggle it all fits Slim, I assure you ....)

My next purchase, its wood trim ... I've yet to back problems ...
