In short, while "Tohoku Zunko" VOCALOID3 and Tohoku Zunko V4 can XSY because they are different releases, but Hatsune Miku V4x "Dark" and Hatsune Miku V4x "Dark" are not possible under normal circumstances. Otherwise, an user can normally register their favourite voicebanks pairs for a future easy use.Īlso note that besides glitches and updates to old software, XSY cannot occur between a voicebank and itself. So when selecting a XSY partner, they will be already registered for selection. Note that some packages, such as the Megpoid V4 vocals, may come with their respective pairs already set up for XSY within the feature. XSY is very similar in concept to how the original VOCALOID engine used recorded analytic data to adapt the VOCALOID engine noise to sound like the vocalist behind the data. Users can also choose how much the second voice impacts the first, from subtle to extreme. Example: A Power-Normal setting will not be equal to Normal-Power.The primary voice is used as a "template" for the morphing, which means the vocal combination used in the Cross-Synthesis is not mutually exclusive or interchangeable, thus meaning the rendering and behavior will slightly be different depending on which voicebank is used as the primary or the secondary voice. The cross-synthesis is not simply switching between two voices as the users draws a parameter curve, but is instead increasing the ratio of the secondary voice being combined with the primary one, in a way that is more complex than a simple fade out. Therefore, if users wish to make use of XSY, some research and planning when making purchases may be required to work out the best voicebanks to invest in.Ī chart of the voicebank packages that support this feature is available on Yamaha's official website.Ĭross-Synthesis will morph the primary voice using the secondary voice as an analytical data guide for the adaptation of the first. Most VOCALOIDs are not able to be registered for XSY and this is particularly true for single voicebanks that are not part of any XSY group, so releases such as Yanhe, Yohioloid and Flower cannot use this feature. This feature works with a selection of VOCALOID3 voicebanks when imported into the VOCALOID4 engine, however not all products are compatible. 2.1 Voicebank XSY variants calculationsįirst, the users must access the Cross-Synthesis Web browser through the Singer Editor, and can assign a Primary Voice and a Secondary Voice to be used in Cross-Synthesis.
