You can play us in real time, using the mouse or keyboard. When you're ready to record a performance, head over to the 'Record your carol' panel where you can lay down as many parts as you like, and re-record each one until you're happy with how it sounds. Once you're done, click on Save and you'll be able to share your creation by Twitter, Facebook or email.
For power users who need a bit more control, there's also the option of creating your song as MIDI file - email us your file, and we'll convert and add it for you. Here's an example file which uses the full range of the choir; anything outside this range won't get played.
