Well, it took a while but after significant experimenting I finally found the cause of the problem and I can repeat it, but only PG Music can solve it.

My view is that it's a bug. Not everyone may agree but I believe 'this is something that the program was never designed to do' and 'was not an advertised feature'.

It is related to this post about the Mixer Window

Steps to reproduce (see images below for clarification):

1: Open a song, it can have all RealTracks or all MIDI or a combination of both. Note the previously set mixer volume and reverb settings.

2: Select Options > MIDI/Audio driver setup. Press OK. The MIDI/Audio window closes and the Mixer unexpectedly closes also.

3: Reopen the Mixer Window. Volumes are now unexpectedly all reset to 90. Reverbs are all set to 40.
