Since I can't download build 420 (I have 2019) I downloaded the latest build (325) Next, I looked for Explorer to go into the drum folder but can't find "explorer". I found a Drums folder in BIAB. Is that what I am supposed to open? Also, I am working with style "M_JPLMSW.STY Jazz Pollwinners Medium Swing" I don't see that listed in the drums folder. Am I even close to where I am supposed to be looking?
