I consider myself relatively new to BIAB 2020, having used older BIAB extensively around 2003-2007. Back then I used to export midi tracks to other apps and then manipulate them to sound more realistic. I have found that one that I relied on a lot for this is no longer available and my old version of it will not run on Windows 10.

My question is:- what is the best way to get realistic sounding instruments from MIDI files?
