I have multiple Japanese CVVC, if you need any good CVVC VB configuration (oto.ini) example, you can DL any of my CVVC. Other good CVVC that isn’t mine are for example Anna Nyui, Number Bronze and Akesato.
I personally like to use CVVC that has [CV] [V C] and especially [V V] settings for smooth vowels. The simpliest CVVC reclist has just 2 mora (syllables). if you’re good at recording VCV VB, I recommend CVVC reclists that are 5~8 mora: recordings this are same than any VCV but much lesser oto and recording than in VCV!
Having [- CV] settings is always a nice plus but isn’t 100% nesessary TBRH, your VB can sound as nice without that.
If you want to oto and record less, pick a reclist that doesn’t include [- CV] settings at all.
If you want any JP CVVC reclist recommidations, just message me
Good luck!
