Emax

When you reseated the IC�s did you use DeOxit on the chips and the sockets?  

You can�t get the connector on the ribbon that�s soldered to the board on the one end, just so you know (I went looking for these just recently and can�t find them)�.
You could try and DeOxit on the male side of the connector, also- although I haven�t heard of the ribbon being a common cause of noise.
Usually it�s the ICs (they can go bad), the sockets, or the reference voltage being supplied for the signal being the problem.

I'm still having problems with distortion coming through all outputs on my Emax 1000 Keyboard


I have an HxC drive installed and I've confirmed the samples are loading properly and not corrupt

I've also re-seated all the ICs on the output board.  


my PSU rails are also showing stable    -12.6v  +12.6v   5.2v

I'm thinking it might be a bad ribbon cable that connects the CPU board to the Output Board


any tips to troubleshoot would be great!
