Default 25 Note Organ Pedal Conversion

Hi,
I acquired an UMR2 on trade me (nz version of ebay),with the intention to convert an old set of organ pedals to MIDI.
I have already wired up the pedals in a 3 x 8 +1 matrix in a active high config with diode on the data side of the switch and used it more or less successfully with a Kawai PH50 as the MIDI convertor.
I will need to add power. Do I need the regulated with a wall wart 6v?
Do I need pull down resistors and if so what value?.
thanks in advance.

Default Resistors are on reverse of board

I now have the pcb in my hand so i can see the resistors. So that problem solved.
I will wire up including zener and cautiously apply power.
will report result for any who may try the same.

Hi Alesis! Sorry for the slow response. I look forward to discussing the project at the MIDI CPU forum.
