It is a mystery to me why PG has not put in more effort to try to implement a more efficient search facility.
With all the musicians/creators of RTs around it ought to be possible to get some input of what it is in the music that makes it a similar style, groove, complementary etc.
Or maybe they have tried but can’t find any way around it.
But now with various AI support packages that seem to become available maybe it will change.
I don’t know how these AI support software works if they come as a package (pre learnt) that the customer just integrate into their software or if they come as a package that the customer can further teach to their specific purpose.
If the latter and if there was such an AI package available that can be teached to recognize similarities in music, then to me it ought to be possible to feed all the BIAB styles and instruments into the AI and teach it what would be good matches, similar music, complementary styles etc. And the human input would probably be limited and only need to go through enough permutations of styles so the algorithms get the hang of it. I don’t know is these types of AI software is available yet.
