New MIDIbox deployment

[johnh]

At long last the MIDIbox is finally a working part of my Residence Pipe Organ.

The MIDIbox translates custom SYSEX messages into controller messages to

interface the console of my pipe organ to ranks of pipes controlled via YAPPI

boards (another PIC project).  Thanks to my friend Craig for working on the

code to do this.  The organ console was built some time ago by another

hobbyist and has 6 8051 microcontroller boards in it and now its first MIDIBox!

The MIDIbox is inline between the stops processor and the MIDI merger.
