As a concept the browser based Daw in general is very attractive
and the Audiotool one is both in sound and in flexibility really interesting.
So what you make with Auditool sketch has the function of uploading
and continue your work in a bigger environment inside the Audiotool DAW
or just save your work in your device as it is a nice little application all by itself...

808 drum machine
909 drum machine
Delay and mixer
And you sequence old school way just like you would with the originals...
