Review: Roland Tweak Synth (S-1): A Game-Changer for Synth Enthusiasts - The Roland Tweak Synth (S-1) has quickly become the crown jewel of my music production setup, and for good reason. This compact powerhouse packs a punch that belies its size, delivering a sonic palette that's both rich and incredibly versatile. From the moment I unboxed it, I knew I was in for something special. First off, the build quality is what you'd expect from Roland - solid, with every knob, button, and slider feeling both sturdy and satisfyingly tactile. The design is sleek and intuitive, making it a joy to explore and tweak sounds on the fly. It's clear that Roland has put a lot of thought into the user experience, blending traditional synthesis with modern functionality in a way that feels both familiar and innovative. But let's talk sound - the heart and soul of any synth. The S-1 delivers in spades, with a range of presets that showcase its capabilities right out of the gate. From deep, growling basses to ethereal pads and cutting leads, every preset is a starting point for exploration. The real magic happens when you start tweaking. The synthesis engine is robust, allowing for deep sound design that can cater to any genre, from EDM and pop to ambient and beyond. The feature that sets the S-1 apart for me is its portability. It's compact enough to fit in a backpack, but don't let its size fool you - this synth can easily become the centerpiece of a live performance or studio session. The onboard effects are top-notch, adding depth and dimension to the sounds without the need for external processing. In conclusion, the Roland Tweak Synth (S-1) is a revelation for synth enthusiasts. Whether you're a seasoned producer or just starting out, the S-1 offers a perfect blend of usability, portability, and sound quality that's hard to beat. It's become an indispensable tool in my music-making process, inspiring new ideas and bringing a level of creativity and fun that's genuinely exciting. Roland has truly outdone themselves with this one, and I can't recommend the S-1 highly enough.
Review: Very compact synth with a very large sound and capability - This is a remarkable little device. Fully battery powered with an internal rechargeable battery that holds a decent charge, and recharged / powered via USB C. Output audio is clean and can be huge if sent through a large system. Built in FX are convenient and sound great. Despite the size there's a two octave keyboard and sequencer, along with a useful relevant layout of knobs. Sound quality is quite good too, advancements in DSP are apparent when a little box like this sounds deceptively analog. I got it with the inclination of it being more of a toy and novelty, but it has the potential to be put to serious use for music making and performance. At the moment I haven't dived all the way to the deep end with it, but I have spent some hours playing music with this. The built in patches are quite good and making adjustments follows the usual synth logic. One downside is that the small form factor cuts down on the amount of buttons or a well developed screen. This gives it a bit more of a learning curve to figure out, as you will have to dive into using it via a manual even if you have extensive synth knowledge. Takes time to get used to the sub menus and the full capability if you want to go beyond just making sound happen. And the only thing I can speak of to detract from this synth is that it didn't come with a 1/8" to midi adaptor cable, just arrived with a USB C cable. Overall I highly recommend this to someone who wants to make music on the go as the portability is amazing. You can put on a sequencer show on the street with this thing! But it can also be a serious tool in the studio as the sound quality is proper.

## Questions & Answers

**Q: What kind of audio output jacks are on the back panel?**
A: There are no audio outputs on the back, just a 3.5mm audio out on the top right of the front panel. I use a 1/8 to 1/4 cable into my mixer without any problems, though I need to push the gain a bit as it comes in a bit softer than my other gear.

**Q: 4 FON. I have a microfreak and a miniKorg. Owned the original SH-101 bk in the day. Wasn't impressed. Would this really be a useful addition? Thanks.**
A: The original SH sound is there in all it's glory, but S1 adds a ton of excellent features, like polyphony! It has a lovely musical filter, a really useful/fun sequencer and amazing reverb and delay. The D motion chip is a nice extra and they used the ACB tech to make this sound analog without the price. Battery powered, midi and audio over USB C. What else are you looking for? It's stupid cheap for what you get and it sounds huge. The only tiny drawback is the red display from the 80s they decided to go with, and some functions are under one layer of menus. Not a huge deal at all and I'll never part with my S1. It's the best of the little aria boxes by a mile.

### ⭐⭐⭐⭐⭐ awesome little synth, with lots of features and versatility. Really fun to play
*by S***I on June 20, 2026*

awesome little synth. very versatile. hours of fun... I purchased a patches pack which adds a lot to it, and can get some classic sounds of out of it. I wish they'd include a midi to 3.5mm cable with it as these are hard to find, and the puny little keys call for a midi keyboard to be plugged in.
