David Bottrill / Mbed 2 deprecated MIDI Stop Controller

MIDI Stop Controller V1.0 suitable for driving Hauptwerk digital organ software. Written for the KL25Z uses BusInOut and will drive up to 16 illuminated push buttons each switch uses a single I/O pin to both drive the LED and act as a switch input. Pressing a button will alternately send MIDI note on / off messages and turn the LED on or off. If corresponding MIDI note on/off messages are received these will be used to drive the LEDs in preference to the locally generated LED signals. The MIDI channel used to send can be selected by jumpers on 4 pins of the J2 header.
