MIDI-Keyboard?!?

[Daniel Oberfeld / SFB_-186]

Hi out there!
And I thought I'd be banned from this list if I 
mention MIDI ;-) !!
But now that Juergen comes up with it:

What I'm dreaming of for a long time (but don't know 
how to do it yet) is to MIDIfy my Electric Grand CP70 
and to use it as a Masterkeyboard.
Did anyone here ever build such a thing (that is: a 
device which scans one or two contacts per key and 
puts out MIDI- note and -velocity) ??
Where can I access the afore mentioned scanning-
schematics, 
and when did this discussion take place (I'd like to 
look it up in the archive)?
Are there any books or articles known to you which 
could be of some use to me?
Maplin Electronics seem to purchase a PCB-kit for this 
purpose, but the description is in their newsletter 
"Electronics" which I can't find here in germany. 
Anyone ever heard of it?
OK, any bits and pieces of information are 
appreciated!!
Thanx a lot,
Daniel
