OT: Ensoniq Mirage RIY

[Glen]

Hello,

I know this list is about designing your own gear, but perhaps someone here
could help me with a "Repair-It-Yourself" project?

I personally have an Ensoniq Mirage keyboard that won't play any sounds,
but the unit does boot up (very slowly), and manages to transmit MIDI data
out to other devices when keys are pressed, or the internal sequencer is
started. All the panel controls seem to be functioning. Only the synthesis
engine seems to be dead. 

Several years ago, I worked at a music store as an authorized Ensoniq
repair person. However, the service literature at that time was basically a
block diagram with some notes that recommended things like replacing large
assemblies to cure minor problems. (Such as replacing the whole mainboard,
instead of changing a single socketed chip.) At that time, there were no
actual schematics being released to anyone outside of Ensoniq. 

Recently, I contacted Ensoniq about getting schematics for this old model,
and they said to "contact my local dealer" and that the schematics were
available. (The local dealer is my old employer.) The local dealer swears
that NOTHING is available for the Mirage. The Ensoniq people INSIST that
actual schematics, and not merely simple block diagrams, are available
through my local dealer.

The trouble is, I'm getting absolutely no cooperation from the local
dealer. (Remember, I used to work for these people long ago, and I can
definitely tell that they are not going to be of any further assistance.)

If anyone has any technical information for these keyboards, please contact
me via private email. (I assume that the list wouldn't be appropriate for
this subject.)

Thank you,
Glen
