Well I just had a big surprise awaiting me.

It felt like deja vu when I made this post. I think I asked the same question many years ago here. The search engine only goes back four or five years so I don't think it would have found my original post.
As I was moving files into my Mark Knopfler folder guess what was awaiting me there?
Four or five different versions of Sultans of Swing!
I had a good listen to them and one of them sounds quite decent.
I don't think I'd be able to create one as good with BIAB so I think I will stick with it.
The funny thing is that the file was created before BIAB started with audio, so the sounds are either midi-based or were played live. They sound like real audio to me.
It's just bass, drums and electric guitar.
It's an mp3 file so I can't do any re-mixing but as I said, the overall sound is quite acceptable to my fussy ears.
