it can't remix. even comfyui can remix on my desktop. I've used udio, suno, comfyui with the music generation models, and one other site that i can't remember the name of since it was through a friend.
They all kinda suck, you do have to run generation many times unless you're very lucky.
I and my friend wrote 10 albums between 1997 and 2007. we went solo for geographical regions, and i stopped writing music altogether in 2017 or so, only doing arrangements, mashups, mastering.
I can't use this google product to make a song. source for credentials is my youtube, soundclick, and soundcloud accounts, e.g. https://www.youtube.com/watch?v=HXro-e0e7aA
and now i don't even know if i ever want to get back into music, because i can rapidly generate a "good enough for the moment" track, like when the south korean president tried to coup: https://soundcloud.com/djoutcold/i-aint-even-writing-music-a... Oh by the way the lyrics are in lojban except for "... and the people were pissed"
the oldest stuff on those three sites i mentioned is all hand written by me over the years.
