I was planning on buying Z3TA+ 2 also - but will not be since the microtonal capability has been stripped out of it.
Cakewalk seems to be going backwards - after the hugely successful 8.5 upgrade features started to be removed in version X1 of Sonar producer and now Z3TA+ 2. This is all very sad.
I compose 1 to a half dozen compositions a day using cakewalk products. I'd hate to have to change my DAW but losing microtonal support is a real deal breaker. Losing the "paint with pattern" in piano roll view was bad enough. It sounds like a manager got in the decision making process who's concern is short term profit instead of continuing the tradition of making a quality software tool for creating artistic work.
