I use BIAB only to generate backing tracks for my jazz vocals. Following a recent reinstall of Ultrapak 2020 from the hard disk supplied onto my laptop, I reduced the size of RealTracks by moving all instruments other than piano, guitar, bass and drums to an external drive unless/until needed again. Due to space limitations on my laptop, I need to move more folders and files, without compromising my current setup which is working fine. I would appreciate any recommendations. Many thanks.
