How to use Miki Yukine act2's Vowel VCV

Here's the UST we'll be using. Playing this UST will make the vowel (o) come out very striking after the "na", since Miki is recorded as having a very strong VB. So here's what we'll do to smooth it out.

Select the "o" note, hold the SHIFT button and right-click the note. This list should pop up, here you choose the "a o".

Here's the result! This way, it will play as "minao" instead of "mina o". This is a technique that can be applied to ANY vowel in his voicebank - thus "vowel VCV".
