Perhaps this is a short clip of where BIAB already is with the use of AI. This is a short experimental clip generated out of BIAB using both BIAB as a backing track and a BIAB vocal converted to a midi to provide the vocal melody for the AI.

This has not been mixed and has only been modified through pitch correction. There is a large amount of control that can be used in both programs.

To further confuse the issue of AI-generated vocals, not all vocals from Synthesizer V are AI-generated.
