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: Great little synth, much larger sounding than it looks - As per the title, there’s a lot of power in this little guy. The ACB circuitry sounds fat and phenomenal with no aliasing I can perceive. Effortlessl apes and sequencing with a 4 voice SH-101 based engine (with a few twists for tweaked). Pretty little thing, too.

## 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.
