MEGURINE LUKA V4X is a VOCALOID4 voicebank from Crypton Future Media, and its defining characteristic from the character's introduction is bilingual capability: Megurine Luka is a virtual singer who made her debut in dual-language software released on January 30, 2009, which supports both Japanese and English vocals, and she is characterised as a 20-year-old female virtual singer with long pink hair, voiced by Yu Asakawa. The voicebank's contents are documented: the new version of MEGURINE LUKA V4X contains two English and two Japanese databases, which were elaborated for improving expressiveness, with the database containing both Japanese and English and compatible with all the functions such as E.V.E.C., Gender Factor, Brightness, Cross Synthesis (a morphing function), and Growl, which can be operated through the bundled vocal editor Piapro Studio. Its specifications are documented: product model number 43926, hard disk space 25GB, with language: Japanese (HARD / SOFT) and English (STRAIGHT / SOFT) — two expression styles per language, which is the specific meaning of the V4X designation. Recommended ranges are Japanese: E2 to F4 and English: G to C4, with a recommended tempo of 50–170 BPM for both. The package includes VOCALOID6 Editor Lite and Piapro Studio at no additional cost, both available for download from Crypton Future Media's official website, where VOCALOID6 Editor Lite is a feature-limited version of VOCALOID6 Editor. There is a practical upgrade detail worth carrying into the catalogue: if you are a user of "HATSUNE MIKU V3" (including HATSUNE MIKU V3 BUNDLE), "KAITO V3", or "MEIKO V3", Piapro Studio will get updated from the VOCALOID3 engine to the VOCALOID4 engine on installation of "MEGURINE LUKA V4X" — so buying Luka V4X brings those older voicebanks forward with it. System requirements are Windows 8.1 / 10 / 11 (64-bit), an Intel Core 2 Duo 2GHz or more, 2GB RAM or more (4GB or more recommended), and 22GB or more disk space in NTFS format. It suits pop, rock, electronic, and vocaloid production as well as bilingual work requiring both Japanese and English singing in one voice. #MegurineLukaV4X #MegurineLuka #Luka #VOCALOID4 #VOCALOID #CryptonFutureMedia #Vocaloid #SingingSynth #VocalSynth #E.V.E.C #PiaproStudio #VOCALOID6EditorLite #VoiceBank #Bilingual #GenderFactor #Brightness #CrossSynthesis #Growl #VirtualSinger #Pop #Rock #ElectronicMusic #MusicProduction #VST #VST2 #VST3 #AU #Standalone #FLStudio #AbletonLive #LogicPro #Cubase
