[Experimental] pretrained models

These are pretrained models from the OpenVPI team.
Note: models are experimental. They are currently consistent with the original repository but may not be compatible in the future. Using these models with main.py is suggested. See more details in the code.

0814_opencpop_ds_rhythm_fix

MIDI-B mode, fixes rhythm errors described in this issue.

0823_opencpop_ds_enhancement

MIDI-B mode, improve performance in high pitch range by shifting pitch of training data with WORLD vocoder, but may cause worse sound quality.

0831_opencpop_ds1000

MIDI-B mode, trained with 1k diffusion steps for better sound quality and pndm and dpm-solver acceleration.

0909_opencpop_ds100_pitchcontrol

MIDI-A mode, support manually editing pitch. It is highly recommended that the pitch must be specified because the automatic predicted pitch is very bad and is supposed to be fixed in the future updates.

0920_opencpop_ds1000

MIDI-A mode, trained with 1k diffusion steps and more training epochs.
