Music through motion:

The AUUG Motion Synth transforms your iPhone or iPod touch into an expressive musical instrument that lets you play notes via touch and shape their sound through motion.

Visit to see a demonstration video.

Available here is the free version of the AUUG Motion Synth App, designed to allow users to easily experience motion-based music creation.

Follow the in-app video tutorial to learn how to play the musical instrument sounds included with the app (See 'SETUP VIDEO' button).

An upgraded version of the app is also available, and has been carefully designed to work with the AUUG Motion Synth Grip. Together, the Motion Synth App and Grip transform your iPhone or iPod touch into a practical and powerful musical instrument. Get yours here:


Play in-app sounds, iOS music apps (e.g. GarageBand), or laptop software through movement:

The AUUG Motion Synth tracks your movements and screen touches to expressively play in-app musical sounds.

The AUUG Motion Synth also allows you to play the sounds of other iOS music apps, giving you access to a vast array of sounds and effects.

You can also play external devices like hardware synths or vocal harmonizers as well as control audio or visual software on a laptop (via WiFi or cabled connections). The Motion Synth app is also compatible with the Music IO app, allowing you to control your laptop software via your iPhone cable (Lightning).


Use the Motion Synth App by itself or with a Motion Synth Grip:

The Motion Synth App has two modes:

1) Single-Key mode (free version): This Motion Synth App mode allows you to quickly engage with motion-based music control, and includes tutorial videos explaining how to use the in-app sounds.

2) Multi-Key mode (upgrade): This Motion Synth App mode is designed to work with the AUUG Motion Synth Grip: a physical holder that securely attaches your iPhone or iPod touch to your hand, thereby improving the dexterity and accuracy with which you can trigger notes via the touch screen.

Just like any instrument. There is a learning curve. The more I play with the better I get the feel of how to use the tool. Very fun to just pull out my phone and do a little thing for the kids and fam. Join in on friends playing the guitar or to just relax and play a chord and work to find the feel and note. Super well done. Have to get the grip to this app asap.

Fun! ... But can be frustrating

It's not entirely intuitive in the way it connects to GarageBand or even more frustrating to another computer. Some of the other features, like adjusting the keys to fit your hand size can be difficult to find, and there are other internal controls that I don't know what they do. So it could really use a decent manual or online instruction.

That said, once I got it up and running it's pretty amazing. Running it through Logic on my laptop you can combine all kinds of sounds using the exs24 sampler or Kontakt Player and get some incredible effects.

One thing I'd like to see in the next version. Since some instruments like the GarageBand Smart Strings can be setup to play chords by pressing a single key, it would be great if the AUUG could interface with that. Currently, even if the smart strings are setup for chords the AUUG still only plays single notes on each key.

Additional programmability would be nice as well. There are a lot of available scales included, but the ability to set each key to a specific note would be helpful for doing more chromatic things and also when setting it up to use premade drum kit samples.

But overall it's very cool and there are a lot of options. Some of the ones I requested may even be in there and I just don't know how to access them yet. Again, a detailed manual would probably help

Most fun I’ve ever had with most of my clothes on

This makes me imagine I’m a musical savant no matter how goofy that may seem it made me feel wonderful and I just can’t stop playing… Thank you for this boost at a time in life and a time in this world where nothing could be more important than satisfaction with something that is Covid compliant
