From the middle of the collective Alligator Gozaimasu comes a musical app, that can record loops, play them back and change the sound with movement.

Use in in an experimental performance with dancers changing the sound with their body movement or have unusual experiences while walking through your environment: Record a short loop, play it back and your movement will change the sound.

Up to 6 files can be played back simultaneously, while each group can contain up to 10 files to choose from – preinstalled or your own.

Additionally, 4 loops can be recorded and played back while using the app.
