To send a midi note, you have to apply a 5 volt voltage (or Gnd) to one
input.
•
The board can supply the power for optical rank if needed, with limit
of 700mA. Some optical kits will be available soon.
Electrical features:
The board needs a power supply that gives between 8 and 15 volt DC. A small
phone (old fashion) charger (8-12volt) will work fine if there is no optical
reader to power.
Please, avoid using an old transformer and just a diode bridge rectifier.
There are 4x16 pin connectors on board (2 for K2M 32). You can wire there
directly your key contacts with 16 wire ribbons. Common of all contacts is the
+5v on the board, so then when you press a key, the +5v is going to
corresponding input.
Ribbon cable and female connectors are available on Orgautomatech site,
