Megpoid V4's two vocals 'Native' and 'NativeFat' will not produce much difference between them. One of the highlights of the cross-synthesis function is that it can produce very different results depending on which vocals are mixed. Those who wished to use Vocaloid on a Macintosh, however were offered only the Vocaloid Editor for Cubase as an option use of the Vocaloid editor on Mac as a normal Vocaloid 4 adaption was not offered. Those who bought the editor after Novemwere also offered a free upgrade until June 2015. įor Japanese users who had bought Vocaloid 3, Vocaloid 3 Editor, Vocaloid Editor for Cubase or VY1v3, Yamaha offered a free upgrade for each software. VSQX files made for Vocaloid 3 work in Vocaloid 4, but they will not work the other way around. Finally, real-time input has been included in this version and is another feature which all vocals can use. This displays the effective pitch curve on the user interface. Another feature included is Pitch Rendering, which all imported vocals can use. Cross-synthesis only works with vocals from the same character, making use with packages like VY1v4 possible, but not packages such as Anon and Kanon. This feature is accessible when using Vocaloid 3 and Vocaloid 4 vocals, but not Vocaloid 2.

Cross-synthesis was also added, allowing the user to switch between two of a character's vocals built for the same language smoothly using a time-varying parameter. One of the new features is a 'Growl' feature which allows vocals built for Vocaloid 4 to take on a growl-like property in their singing results. The new engine includes other features, but not all of them are accessible by Vocaloid 2 and Vocaloid 3 vocals.

The Vocaloid 4 engine allows the importing of Vocaloid 2 and Vocaloid 3 vocals, though Vocaloid 2 vocals must have already been imported into Vocaloid 3 for this to work. The update of the AH-Software Vocaloid 2 vocals is related to Windows 10 being released in 2015, and the impact it may have on the Vocaloid 2 software. All AH-Software vocals were also announced as receiving updated packages as well as VY1v4. A Vocaloid 4 version for OS X has also been released. Its release was delayed so it could be released on the newer engine. In October 2014, the first Vocaloid confirmed for the Vocaloid 4 engine was the English vocal Ruby.
