I know also that as they moved the platform into the online format it really didn't work as well for me. I appreciated the free offer they gave us last year - and tried using it for a bit - but it was just not that reliable. PracticeFirst generally speaking has been a lot more reliable, it's just a pain to make your XML files and import them.
I don't know that we'll actually ever see a comparable product back on the market though to what SmartMusic was in their best years. In order to accommodate the rights I have to imagine they would have to raise their rates significantly more than they already have.
For my part I don't see renewing with SmartMusic in the future years.
