## Review summary

SynthMaster One for iPhone offers a feature-rich, high-quality synth with intuitive UI and strong GarageBand integration, praised for its microtonal options and sound design flexibility.

Overall it’s a capable, versatile instrument that shines when it runs smoothly.

- Excellent sound quality with a powerful low end and wide tonal range
- Intuitive UI with visual signal routing and easy patching/sequencing

### Cons
