Midi Channel selection
Midi channel is selected by four lines which must be either floating or be grounded. The
simplest way to set midi channel is with a 4-way DIP switch which shorts the data line to
ground. 0 is switch closed (ON) and 1 is switch open (OFF). Binary codes are being read pin
4
to pin
1
. Pin 4 is MSB, pin 1 is LSB.

For example, to set midi channel 3, set the DIP switch to 0010. That is, 1 on, 2 off, 3 on, 4 on.
