Voice Color (Voice Color) is one of the core features that differentiate OpenUtau from traditional UTAU, and the steps to implement it include:
- Voice bank preparation: Ensure that the voice library contains recording samples in multiple registers/tones and that alias aliases are properly defined in oto.ini.
- Color Definition: Create different CLR parameter values (e.g. 00 = regular timbre, 01 = air voice color) via the Voice Bank Editor.
- Real-time switching: Select notes in Piano Roll, select the target tone code in the CLR parameter field, and support drawing smooth transition curves.
This feature is particularly suitable:
- Performance of the emotional dynamics of the song (e.g., main chorus and chorus timbre changes)
- Multiple chorus effect simulation
- Creation of special sound effects (e.g., fading from solid to airy sounds)
Note: You need the voice library creator to pre-record samples of different vocalization styles, ordinary UTAU single tone libraries can't use this function directly.
