Idk,
I planned a lot
CV
VCV
multipitch+falsetto
Appends(Soft, whisper,dark,cold,warm,mature,pure,nature,lyrical,serious,power and one more I forgot)
Language pack(Spanish, English, Korean and one multilanguage for Romance Languages[exactly for that, I’m studying about the iPA vowels and consonants])
VCCV
Extras(breaths, laughs, consonant clusters for other languages)
And a project to make syllables from phonemes.
(Maybe I’m forgetting a lot of ideas but I’m not sure to write them all)
But I need more experience for the appends and language packs, so I’m only sure to VCV and multipitch+falsetto and those are enough for my UTAU.
