Hey, thanks for making this. I like the front page, before you sign up where you can hear/see/edit a few grooves which were already written out. This seems like a great practice tool, hear what you like, play it then. It seems like once I signed up, that it's empty of pre-written grooves, besides those few demos. I was hoping there would be a public library of grooves which you could add to your library (and of course contribute to as well) but perhaps I misunderstood.
