Excellent - thank you very much :-) It is exactly the feature I always
wanted!

Here are all the "House" recordings...  Note that most of them are
about 8 but some are -1 and -3 - I think these are the troublesome

I add and subtract a few points for what channel things are on, hence
the fact that they aren't all +8 or -4.

That is my next plan but I need to find a bit of free time first!
