Just to comment on the ease of the Midiboy build and setup , the quality of the examples:
i was within 2 evenings able to have a working sketch and device that did part of the needed midi conversions, functioning in my rig (using beeps to communicate).
I have now finished the Sketch including everything but the display and menu control.
(Will finish when the new display arrives)
The project is about having a device in between my AxeFx and other older midi equipment, that converts AxeFX midi scene commands into something usefull on the other equipment.
