Robh,
You need to back away for a moment. You're settings are not lost if you saved your songs after all the tweaks. Trust me. If this were BIAB different story. Now a question;
1. are you using Sampletank inserted in each track or is it being used as the default synth?
2. do you by chance have two copies of the songs,ie, before and after fixes and you're loading the wrong ones?
3. uninstall the VSC and go back to PREFS and reset the default synth to Sampletank and see what happens.

If you get this all back do what I do. Render each track to audio when you have it set and tweak the audio tracks. I have over 200 songs like this and they never miss a beat. All straight audio.
