FATAR 88-key connector pinout

[to-pse]

Hi everyone,

I have a 88-key FATAR keybed here, which I'm trying to build
a key-scanner / midi-encoder for.

Does anyone here have any info on how those AMP micromatch
pins are connected to the diode scan-matrix?

I know that I can just measure it out to a certain point. But as
there a two contacts for every key (for velocity sensing), I
would not find out which one closes first and which last...
