"Xynthesizr is about the only tone matrix app that can keep up with my short attention span. There are so many ways to shape, and constantly reshape, your sound... There's a lot to play with here!" - Tim Webb, discchord.com

"Overall, Xynthesizr is a very interesting instrument that is fun to play and lovely to look at." - Tom Flint, Sound on Sound

"Xynthesizr holds a lot of creative potential, and between a user friendly interface, a practical onboard synth, inspiring generative features, and solid MIDI implementation, this is a useful tool that can really benefit a wide range of iOS musicians." - Chip Boaz, iosmusicandyou.com

"...one of my absolute go-to apps" - Sean Garland, iosmars.com

### 5/5 — Excellent

*2026-06-27*

Hasn’t been updated in years probably because it was made so well.
Well worth having.

### 3/5 — Klare 5 Sterne wenn auch AuV3 kompatibel

*2025-12-31*

Leider lässt sich xynthesizer in keiner meiner Programme integrieren , was wirklich sehr schade ist. Wäre ein toller Mehrwert wenn es solch eine Funktion gebe. Wäre auch bereit einen kleinen Obolus dafür zu bezahlen.

### 5/5 — AUV3 NEEDED

*2025-12-03*

This is still a great app, but can you please make it AUV3 compatible? This would be absolutely insane inside of AUM.

### 3/5 — AUV3 please!

*2025-11-15*

For 2025 just interapp it’s not good

### 2/5 — No development for years already

*2025-03-21*

Good sequencer and synth but I don't think the developer is interested in developing the app anymore. No auv3 support or other updates for years!
E.g. on iPad os 18 the synchronization with AUM does not work well. 
Too bad. It would at least be fair to mention this in the description.

### 5/5 — Wonderful app for making music on the go

*2024-11-20*

This is a great app for making music on the go.
Great sound and nice user interface.
One feature I would happily pay for would be the ability to have different sequence lengths for the different sections.

### 5/5 — Супер

*2024-10-19*

Супер Синт с удобным секвенсером. Пользуюсь много лет

Пожалуйста сделайте start/stop при синхронизации

### 5/5 — This is a bug not a feature

*2023-11-15*

Lovely and fun sequencer and synth but one glaring issue: fine tune won’t work when you land on a incremental BPM for example 73.3. If you have ever shared files between devices or friends you know the problems a decimal can bring. This is when you need fine tuning! Unfortunately fine tuning control only changes the number before the decimal. Maybe the dev needs to Google what fine tuning means? Idk I hate anything that is not exact BPM. No more wishy washy in between beat counts please

### 5/5 — Leider geil!

*2022-09-10*

Please(!!!) upgrade AUv3 Support and extend it for 64 steps.

### 5/5 — Best generative sequencer

*2022-06-12*

AUv3 support would be a great addition.
