I hope all of you doing well....I own the whole vienna super package even the download products and my vienna library one the the best I own but the problem is vienna team doesn't care about quarter tone ! most of turkish and middle east musician even in europe miss this option ! Most of them really looking to buy most of your products but they avoid to buy when they know there is no custome microtuning in VI engine! at present most of the play engine such kontakt 3 and Yellow tools products and DVZ strings V2 and omnisphere and play from eastwest and others they have this future for example I can detune the root key C from 0 to -50 or +50 or both keys E and B from 0 to -50.I appeal to VI team especially Herb to develop this feature in the next update..
Kind regards.
