The Yamaha AN1x Synthesizer mailing list

Hi folks!
Sorry if this one has been up for discussion before, but my 4 year 
old daughter and a friend of 37! were messing about and managed to 
send my AN1x crashing to the floor and damaging (only) one of the 
keys.
Now, i think someone said there were 68 screws or similar to undo 
just to get to the keyboard mechanism inside... has anyone done this 
and replaced / fixed a key themselves?
I'm slightly worried now that I've removed the case, found a couple 
of bits of broken key... it's really hard to see inside and look at 
the mechanism, can anyone offer any advice...
I'm devastated as I use it as a control synth and don't have another 
keyboard to use, and am not a rich man....

Any help / advice appreciated!

Thanks
steve
