Patches and discussion for Ensoniq VFX family

Replacing the cpu seems a bit odd to me. I would expect that if the cpu had failed, there would be other issues as well. Hardware-wise, it seems possible to me that an I/O or data line could be damaged either in the cpu or on the board, but without a schematic I wouldn’t be able to tell what that could cause.

Seems to me more likely an issue with software. Have you tried re-initializing the keyboard? (reloading the OS is not the same.)

The major weakness in the SD1 appears to be the “ribbon cable” between the two boards in the keyboard causing various problems. Do you get any calibration error messages?

I noted in my original post that the problem started after using the SD1 at a venue without plugging it into a surge protector.  There was some sort of power spike and the machine got scrambled and rebooted.  Prior to that it worked perfectly.
