Gracias, kind sir.  
 
That is quite a box! I like it.  
 
I don't suppose you could pass along the software for it?  
 
 
I am pretty unfamiliar with midibox software. How embedded are the 
defined controller ids? For example, in LC_IO_TABLES.INC there are the 
list of button and LED assignments with their respective shift registers 
and defined hex values. For the hash-defined parameters #define ID_REC_RDY_CHN1	 
through to #define ID_REC_RDY_CHN8, would it be possible to extend this to  
#define ID_REC_RDY_CHN24? Provided of course, that I cull a bunch of unused 
parameters to free up their hex values.
