I saw this in some John Hardy Documentation:
If you look at the schematic there is a separate 5v PSU for the LEDs for the switches in the project
Is this to keep the current in the circuit or is it to stop the circuit getting "dirty" current (I apologise for my newbie lack of understanding here)

Look at the MPC1 schematic on Page 6
Also one thing is bugging me - which switch do I use and how do I wire it...
Thinking on my feet here - are my assumptions right...
I have a SPST switch to switch a cicuit in and out
If I know want a LED to show this circuit is in or out AND i use a LED PSU to feed the LED
Then which switch do I use and how do I wire it?
Is it as simple as a DPST switch which pushes the LED circuit in at the same time as the audio circuit...
