Fatar TP9S 44 note keybed pinout

Today the Fatar TP9S 44 note keybed I ordered arrived so I set about going through it with a continuity test to get the pinout for the diode matrix. This wasn't anything I'd seen anywhere online for the 44 note keybed; Doepfer has the 37 key and 49 key matrixes up on their website but not the 44. Turns out the connector on the 44 is the same as on the 37 key, a 20 way Micro-Match connector. If you're looking for the mate for it to run to your electronics the male part is here (Element 14 link).

Here is the pinout for the 37 key model from the Doepfer website:

The 44 key has the same pinout on the connector with the addition of another lot of MK/BR contacts on the last two unused pins. The order goes round clockwise so the far right pin is MK5 and then other BR5.

The keyboard pins will be wired up to digital pins on the Arduino so they can be scanned to detect keypresses. At this stage velocity sensitivity is not required so the timing data between break and make is not required, which makes the programming a lot easier.
