[sdiy] flaky keyboard on Mirage

[CCartCat at aol.com]

Just wondering if anyone has a idea about this:

My Mirage has an intermittant problem with the keyboard.   It seems I can 
reliably control the Mirage's own sound engine via the MIDI in and send out pitch 
bend and mod wheel info to other MIDI devices.

But the keyboard itself will flake out, no longer playing either the onboard 
sounds or anything connected via MIDI (nor will it make the LED display get 
all squirrelly as Mirage displays do when the keys are being played).   

Rebooting (in either standard OS or Soundprocess) will temporarily solve the 
problem, but often within minutes, if not seconds the keys go dead again.

I've opened the Mirage up and reseated the keyboard-to-circuit board ribbon 
cable at both ends.   This seemed to make things work a bit better, but problem 
soon reoccured (making me wonder if it was a "chance" improvement at best).

Just wondering if the keyboard or something on the circuit board could be 
wonky (and not the ribbon cable).
