Good review! As a former owner of a Matrix 12, I agree with your assessment.The Matrix 12v is 95% there, and truly, when in a mix you'll never know the difference. I've heard people say the vst is not a warm sounding, not the same, I can only think that they've never owned one or had any significant time with the actual synth, because if they did, they wouldn't be as critical as they are.
As a former Matrix 12 owner, I am very satisfied with my new Matrix 12v.
