Critic Reviews

Moog Slim Phatty

soundonsound.com

The Moog Slim Phatty offers a classic Moog sound with its robust monophonic analog signal path. It's a solid choice for those seeking simple, iconic sounds, and its alternate scales feature adds unique versatility. However, the synth suffers from limited modulation options, a complex menu system, and lacks key features like aftertouch and a noise generator. While the sound quality is undeniably Moog, its price and functionality may be best suited for Moog enthusiasts, especially given that competitors offer more features at a lower cost.

Moog Slim Phatty Review 2022 — Kulshan Studios

kulshanstudios.com

The Moog Slim Phatty delivers the classic, rich Moog sound with fat oscillators and the iconic Ladder Filter, making it a solid entry-level choice for those seeking the legendary Moog tone on a budget. However, its analog nature leads to tuning instability, requiring a warm-up period, and the limited modulation options, including just one LFO, may restrict sound design versatility. While it excels in basses and warm leads, the lack of onboard effects and complex modulation capabilities might deter those seeking more flexibility. Overall, a decent introduction to the Moog world with some caveats.

Moog Slim Phatty review | MusicRadar

musicradar.com

The Moog Slim Phatty offers a compact, affordable alternative to its sibling, the Little Phatty, while preserving the core Moog sound. With a reduced price and footprint, it features the Little Phatty's sound engine, USB MIDI compatibility, and a sleek, portable design. However, it sacrifices the keyboard and mod/pitch wheels, and its control panel is more crowded. Despite these drawbacks, it provides an excellent entry point for those seeking the Moog experience. The Slim Phatty stands out as a cost-effective way to introduce Moog's iconic sound into any studio setup.

Totally underrated Moog synth, albeit with a couple flaws

Lotta folks slept on this one, which is kinda weird, but also kinda makes sense. Its sound is total classic Moog vibes. I've been pulling classic 80s basses and leads out of this thing like it's nobody's business, and you wouldn't know the difference from the originals. And I can also pull Trance and Techno sounds out of it that would fit in a modern song today.

But then it also has annoying tuning stability issues, and a super limited modulation section, and no white noise. a white noise generator would be really nice on this thing. And even having 2 mod sources that access the same parameters would be handy.

Having said that, the patch storage and the super fat warm sound is nice. I don't use this synth all the time, but when I do, I enjoy it. Always adds recognizeable Moog sound to any tune I use it in.

If you can get one, get it. Just give it time to warm up.

Great sound and control but tuning issues not great

This thing sounded really nice and happy sounding. Hard to get edgy tones out of it so I sold it but for the specific moog sound it was fantastic. The one real drawback tho was that this synth takes like 30 minutes to warm up which just killed my whole groove with it. We should be able to design synths that tune up and stay in tune better than that by now

Splendid

This was my first Analog Synthesizer and DAMN is it a nice one. It sounds so nice and is built so well. The thing I'd say is wrong is how the "VST Editor" for it thats about 70$(?) and refuses to work even kinda for me for thats not a really problem with the synth.

Wait so you have to buy a separate VST editor for an additional $70? That seems kinda weird.

@gchiaren yeah it is kinda weird :\ the synth is still totally functional and all you just cant easily automate anything.

Damn. For the price tag on it though it's a weird move not including the editor software. Oh well still looks like a pretty sick synth, you're lucky to own it :)
