Thanks, Noel, for your detailed suggestions. I’ve now tried out most of the suggestions I’ve received. I went through yours one by one, but each time the Mixer RealDrums became MIDI when rendered to Audio, until I tried the last resort, Factory Settings/ALL. This time Drums remained green in Audio, but now the other tracks weren’t Muted, like they’re supposed to be in Audio (how’s that possible?)

Later when I was using ctr+shift F8 to load a previous song, I accidentally hit F6 instead of F8, and - lo and behold - the green Drums track turned yellow across all my songs. Ctr+shift F6 is defined in the shortcut list as “enable/disable RealDrums.”

So it would have been easy to say I just clicked a wrong option by mistake, except the green-to-yellow change in Drums only happens (automatically) when the song is rendered to Audio. After that, of course, ctr+shift F6 has no effect. When I “unrender” the song from Audio, the Drums track automatically becomes green again.

So I guess I’m stuck with MIDI Drums for Audio songs until I figure out what’s wrong.

/Best, Bent
