Alun,

The only thing I can think of is a faulty pad. The rim shouldn't be able to stop it working, even if the rim switch is held down.

I am sometimes suspicous of the red knob. Very occasionally I have had to twiddle it after transporting it to get it to work properly.

Your description implies a link with the module playing songs, but I cannot see how there can be a link. Are you sure they are linked?

You could try swapping the cable and trying it in another input (although your choice of 3 zone inputs is limited).

Keith.
