Online Music Creating with Aviary

Aviary is a free suite of powerful online creation tools. You can edit photos, logos, web templates and more, but I’m not very good with graphics – until now I only use Aviary for screen capturing.
Now they have released their online Music Creating tool. Of course it cannot compete with FLStudio or Ableton Live yet, but OTOH it is still in beta and offers already 50 instruments, mostly beats. But there is more to come, so I’m curious what will be the future of music making with Aviary.
So here is my first effort; just a simple beat. But that was before I sent out my five invitations to unlock more advanced features, that I haven’t explored yet.
