I might go over all the UTAUs made for this project. There’s not only info about UTAU but also some sections on music theory and mixing, and guides to popular reclists including English ones.
I really wish this had been around when I started using UTAU, I definitely would have used it. The PDF and Epub downloads come with the magazine/booklet itself (180 pages!) and the ISO download comes with plugins, programs to record an UTAU voicebank, and a large selection of voicebanks to try (you don’t need to get an actual CD for it or anything even thought the site says DVD-ROM). UTAU Starter Pack -Overseas Edition- Website + Downloads Somehow, I only just learned that the overseas UTAU community put together their own version of Windows100%! The magazine was released (in PDF form) in March 2020 and unlike Windows 100%, it is totally free.
