God you make me feel old, I think the last century bit made me reach for my zimmerframe and I'm only mid 40's

Thanks for the lead, I'll google colour (or color) organ and see what I get.

No worries on the mains isolation. I use solid state relays that have built in opto isolation. Its a lot safer and easier than messing about with triacs and thryistors like the good old days... I built my first sound to light in '77 consisting of a three way passive crossover, three mains to 6v ac transformers (using the secondry as the primary on the audio) and three 206 thyristors... never really thought about the amp become live at mains potential !!!!

I'll keep you guys posted of any development I get, and hopefully Melanie may let me post the final project and schematic in the respective forums when its completed.
