Features & Capabilities

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)

User Reviews

GyroSynth is a fun, innovative gesture-based iPhone synth that uniquely uses the gyroscope to control a sampler. Reviewers praise its playful experimentation, sample playback capability, and live-use potential, with professional musicians noting its viability for performances. However, recurring issues include startup crashes on older iOS versions, unreliable recording/sample playback, occasional sound drop-outs on some OS versions, and requests for more frequent updates and broader compatibility.
Pros
  • Fun to use with lots of room for experimentation.
  • Gyro-based gestural synthesis offers a unique, responsive control experience.
  • Can play back samples / sample playback capability, a standout feature for iPhone.
  • Strong live-performance potential and has been used in live sets; supports MIDI/Audiobus.
Cons
  • Frequent startup crashes / app not opening on iOS 8 and other iOS versions (compatibility issues).
  • Recording/sampling functions sometimes do not work or are unreliable across updates.
  • Occasional sound drop-outs or no-sound issues on certain iOS versions (e.g., iOS 16).
  • Perceived lack of ongoing updates / maintenance and compatibility updates for newer iOS versions.

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

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.

No sound no matter what I do. Does nothing.
