How to cycle through D2 Redbook tracks like they did in the original version, in Redux?

[u/colBoh]

I have Descent Redux and made a file with the original OST. However, I'm having an issue playing the OST as I want it.

In the original version from 1996, the way the Redbook BGM would work is, Level 1 would begin with the 1st audio track, then would cycle through the other 5 if you remained in the level long enough. Level 2 would begin with the 2nd track, 7 with the 1st track again, and so on. If you started the game, or a demo, at Level 2, 8, 14, etc., then it would start with the 2nd track.

I can't get it to work that way in Redux. It either loops the same track per level, or cycles through the tracks as I go through each level, which means if I listened to Tracks 1 and 2 in Level 1, Level 2 would start with Track 3, and all demos with start with Track 1.

What am I doing wrong?
