Thanks man, i had read that already...i understand it now tho with further investigation...ive found now when designing your midi box (after the interface has been designed) that if you draw out the individual parts that are listed in the MB Hardware platform...i.e your DIN Module, Core, AIN Module etc.. and conect them all up it makes it a lot easier to understand how your machine is going together...ive done mine out in cad and i would defiently reccomend it for somebody llike me with no experience...ill post the drawing file when it is completed...its also a good way to show somebody if your device isnt working and they can see if your circuit plan is correct...just a thought ;-)
