Disklavier

> 
> ha yes, you can hear the mechanism engaging and disengaging when pressing the QUIET button

to clarify , that ISNT the solution, still got no keys working.
Ive revised the problems below.

Yes midi out is working, i can control a synth from the MIDI out
Also Midi in is working as I can play the internal piano voice when I connect the headphones from an external midi keyboard

The pedals respond but not the piano keys.

I also cant connect or pair my PRC100 to the disklavier, tried lots of different settings but it cant find the piano.
Anyone know all the correct settings to pair these two?

BUT I can connect to the disklavier from dkvbrowser on my mac and play files, although its only moving the pedals.

The red LED number 4 on the Power supply unit is on, the unit the mains connects to.

Any ideas?
Any help much appreciated!
