Besides, left alone, BIAB backings lean towards the generic or bland.
Couldn't that be at least part way remedied by bring in some new blood to play the track samples? Outside of the same small handful of prime time names...
Oh, definitely!
The reason so many of the "styles" suggested, based on songs/artists nominated in the search box, are completely inadequate is that it's resourced by a limited number of players and recordings.
The stuff labelled as "metal" & "punk" don't sound like those should sound because, largely, they aren't.
There is an over supply of Mr. Mason: he's perfectly adequate across a range of styles but, because they are him, they all sound like him. As it stands I don't use him because the himness doesn't fit anything I do.
There're no real new wave or punk bassntracks, no drums to suggest Happy Mondays, New Order or Joy Division and so on.
I don't blame BIAB for these things - the catalogue is so heavily based on its jazz and country roots that it's a big ask & task to spread things.
Your response is the reason I'm so critical of the style picker/chooser/thingy...check out the origins of the drums n bass and it's clear that the "style" is a stretch of more than the imagination.
Nevertheless its a fab program.
