Okay... I got it all downloaded and here's a few first impressions:
The Gallery window is laid out like Addictive Keys with descriptions of the AD Paks.
The Explore window is pretty cool for getting started on finding kits to work with and auditioning AD Paks for future purchase.
The Kit, Edit and FX windows are pretty similar to what I'm used with AD 1. The Kit page lost the full kit image center screen but there are more slots for additional kit pieces. For some reason I like the AD 1 graphics better than AD 2.
The Beats page is a huge improvement over AD 1. I love the new lay out and search features.
The Map window so far looks pretty similar to AD 1 to me.
I won't comment on the sound quality yet as I've only been playing with it on my laptop with the default sound card and speakers.
I am pretty happy with this upgrade and I can't wait to have a real listen to it.
