I have it already so I'm just cancelling. But just for UTAU the freeware option is enough. It's not very expensive and seems quite good. The first one is a profesional music program. And we are in the download zone for some programs. The one I'll use is the freeware Musical Studio Producer. All the files you'll need are: -the UTAU program and a voicebank (you're in the wrong tutorial if you need info on this) -a midi file with a vocal track (I just googled it) (this midi is in mode 0, the incompatible to be used with UTAU) -and, finally, a program to work with midis. This tutorial will use a freeware midi creator.
Welcome to this tutorial of importing midi into UTAU.
