Having a moment... cannot find melody/harmonization video(s)

[AxBC]

Hello,
I thought I had seen some videos that demonstrated building a song where if one starts with a chord progression, additional track(s) can be added for various instruments, and additional tracks are generated to harmonize and/or generate melody.
Can anyone point be to an example video or two?
Thanks!
