Record songs with only your voice - no instruments required!

This is a web application that uses your voice as a substitute for instruments. You can sing or beatbox into your microphone, and the app will convert the sounds into the instrument of your choice.

How to use

• Click the big yellow button to add tracks.
• Chose what type of track you want to use: instruments, drums, or live vocals (currently in development)
• Select the instrument you'd like to use.
• Sing!
• Wait for it...
• Layer more tracks for more tunage.
• Change the tempo with the arrows around the BPM indicator.
• Make an account to save and load songs.
• Export your tune to mp3 or midi (currently in development)
