Unfortunately, this feature has been eliminated because of the new architecture.
Too bad God would not give the programmers the ability to design a "new architecture" that would support one of the breakthrough capabilities of electronic musical instruments i. e. rapid and easy scale adjustment. Perhaps if they prayed instead of programmed, a miracle would happen that would allow them to write code that was not lame by design.
Frankly I think they just realized that the trance cut-and-loopers who they now view as their target audience for softsynths have no use for tuning of any sort.
No, I would not buy a contemporary synth that does not support microtuning. But I expect I will end up getting one free if I upgrade to Sonar X2 producer in the near future.
