## What is GyroSynth?

GyroSynth is a gesture driven music synthesizer, which takes full adventage of the gyroscope. You can play and modulate the sound by moving your hand through the air - just like the legendary Theremin instrument.

GyroSynth makes use of the gyroscope to measure true roll, pitch, and yaw and translates them to sound parameters like pitch, volume, modulation or filter cutoff. Thanks to phenomenal accuracy (2000 degrees), you can play melodies perfectly in tune.

A finalist in 'Most Innovative App' category at the 2010 Best App Ever Awards (148apps). 
GyroSynth has been used in numerous live jams and performances (e.g., Mindex)

### 5/5 — Love this

*2026-06-18, version 2.8*

Excellent!!!

### 1/5 — Nice idea but useless

*2025-09-27*

This would be quite useable if it worked in AUM or Audiobus with some lush delays etc but it doesn’t. Both see it but can’t launch it, so no good to me and deleted it gets!

### 5/5 — Most fun instrument!

*2025-08-04, version 2.7*

I hope more people download this and they develop it further. It’s so so good and so so fun

### 3/5 — PLEASE update this Synth!!

*2024-11-29, version 2.7*

Because it can‘t be load in AUM. If this would be fixed, this App is wonderful

### 4/5 — Great App!  Needs one thing….

*2024-05-24, version 2.7*

I love this app.  It’s the only gestural synth that can play back samples that I am aware of on the iPhone.  I really love it.  However, it only allows file sharing with iTunes.  You can’t connect to Google Drive or even Dropbox to load samples into it.  I know it is asking a lot of a free app, but this is so well done.  If they would just add Google Drive downloads or at least enable sharing with the AudioShare app.  If the developers read this, please, please add Google Drive as a way to import audio files.  I  am an experimental musician and like to edit my samples on the desktop, not my phone.  This would raise this app up a notch.  Heck, I’d pay for that option.

### 1/5 — No sound

*2023-04-25, version 2.7*

No sound no matter what I do. Does nothing.

### 1/5 — Doesn’t work

*2023-04-14, version 2.6*

It just works on 1st time once installed later nothing happens… I tried it on iPhone 13. Fix the issue and release the next update….

### 1/5 — Crashed and would not work

*2023-02-18, version 2.6*

Bought app today and worked great first time around. Tried a second time and it did not work.

### 2/5 — Non funziona più

*2023-02-02, version 2.6*

Peccato, perché era divertente. Occorre sicuramente un aggiornamento.

### 3/5 — It's one of my favorite apps.

*2022-12-03*

But since I updated to iOS 16, there was no sound at all.

Of course, Drambo can do something similar, but the nuances are a little different and it doesn't sound exactly the same feeling.

I would like you to respond with an update.

I look forward to working with you.

## Frequently asked questions about GyroSynth

### What is GyroSynth?

GyroSynth is a music synthesizer app that utilizes your device's gyroscope to control sound parameters. You can play and modulate sounds by moving your device through the air, similar to a Theremin. It offers various synthesizers, effects, and recording capabilities.

### How does GyroSynth work?

The app uses the gyroscope to measure roll, pitch, and yaw. These movements are translated into sound parameters such as pitch, volume, and modulation. This allows for expressive, gesture-based control over the synthesized sounds.

### What types of synthesizers are included?

GyroSynth features several synthesizer types, including a vocal (formant) synthesizer, sine wave, square wave with PWM modulation, saw wave, a granular sample player with recording, and an experimental FM modulation option.
