Moresampler only generates a base OTO roughly based on the samples, and it will always need to be adjusted to completely fit the voicebank. If you release the voicebank before adjustments, you should label the voicebank as a beta version.
To adjust the OTO, you can either use the built-in OTO editor or
setParam. If you only need to adjust a single note, you can select that note then press Ctrl+G to open it in the built-in editor. If you want to adjust multiple notes in a UST, you can select all of those notes and run setParam as a plugin. To edit the whole voicebank, you can either press Ctrl+G without selecting one note by itself, or run setParam as a standalone application.
To adjust a VCV oto, keep these three things in mind.
- From offset to overlap: Previous vowel, consistent tone/volume.
- Preutterance: At the end of the consonant. (For consonants like "ky", it should go after the "k" and before the "y")
- From fixed region to cutoff (white area): Next vowel, consistent tone/volume.
Essentially, every VCV OTO should look something like this diagram.

Here's an example OTO that has been annotated for clarity.
