I can't speak for UTAU-Synth, but on PC, I'm 99% sure it doesn't ignore the oto settings. If you use $direct=true on a VCV note, it'll still use whatever preutterance and overlap you set. It's almost like those settings tell it how much to "directly play." I'll double check it later if I have the time!One more question: When "$direct=true" is set, does UTAU also ignore the consonant length, preutterance, and overlap from the OTO file? If so, I'll be able to implement it without much trouble.
