Create sounds and load samples

Drop them where you want on your controllers then start jamming!

Everything you play is recorded.

Hit the loop button at any time. Whatever you just played will start to loop!

Play to the beat.

Use beat repeat and hold down buttons to trigger at different rates relative to tempo.

Transform your loops while they play.

Select, move, repeat, suppress. All using your hardware controller.

Troubleshooting

If you receive an error on start up about missing lib/*, you may have to run the following as administrator:

If it still doesn't work, try copying the /lib folder into /node_modules.
