I've checked that that no other strip is set to quad, but even so in this project, my Master strip shows quad, even though there's no button to change it. Consequently, there are no insert slots and I can't import my favourite settings. If I use simply Output 1-2, my favourite settings don't appear in the preset menu - I need Master to unify with the other projects in this album. How do I set my Master to stereo, which I guess would open the insert slots? I doubt that it's my general Prefs, since the related projects have active and configurable master strips. pete Correction: when the Master channel strip is active, it shows as quad and my Output 1-2 strip loses it's insert slots. The Master strip allows inserts but none of them are my library.
