OK thanks for the clarifications.
I like Sonar a lot but for some reason I have a psychological resistance to the whole membership idea. I think the difference is that before, when I would upgrade to the newest version I would get new third party plugins or whatever which made it a very good value. Without that aspect $100/year seems steep and I may just sit it out, which is a bummer because then I can't get bugfixes or speed enhancements. I'd be more likely to jump in if there were more improvements on existing functionality, such as improvements to ACT, step sequencer, arpeggiator, drum maps, etc.
Anyway I'll quit my whining now, thanks!
