Nice idea but useless

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!

Most fun instrument!

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

PLEASE update this Synth!!

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

Great App! Needs one thing….

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.

FAQ

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.

Can I record my music with GyroSynth?

Yes, the app includes a built-in recorder and player with an overdub function. This allows you to layer sounds and record your performances directly within the application.

Is GyroSynth compatible with my device?

GyroSynth leverages the gyroscope for its core functionality. It is designed to work on devices equipped with a gyroscope, allowing for precise motion tracking and sound manipulation.
