inb4 a mod comes here to address derailing...
What I'd like to see is...
- Multitrack: implemented (more or less a beta feature?) in UTAU-Synth, not present in UTAU for Windows (there's a plugin to play multiple windows at the same time, but it's not the same as having everything in one interface).
- Lose the Rests: again, this is in UTAU-Synth. It would be nice to edit or create a UST within the program itself without Rests being a risk factor (timing being off, etc.)
- Ability to read Unicode scripts (non-Japanese and non-Cyrillic alphabets like Korean, Thai, etc. can be used, rather than inaccurate romanization)
- BGM import like other vocasynths: It's 2016 now. No reason why we should still be making midis in a 3rd party daw or rely on vsqx -> vsq before getting to use UTAU itself with the intended voice. It adds an extra step (and expense) to creative pursuits.
