Guys, thanks once again.

I'll try the changes a little later and see how I get on.

If I read that table correctly, by entering the value in the left column, AN0, AN1 etc are set accordingly. So for example 0000 would cause all the pins (AN0 - AN7) to be analogue. 011x would do the opposite and make them all digital ?

I take it the $0f etc is just the Hex value for those dec numbers 0000 - 1111 ?

was good for the previous PIC18F2550... which, i feel, will gather dust for awhile
LOL - yeah.. you're probably right !

For an audio trigger... i would use a analog comparator instead as they react way faster
Steve, when I'm ready for looking at using music for the sound to light / chaser component I'll be interested to hear your suggestions as i've never used these sort of functions on a PIC before.

Thanks again
