MP-1 wierd midi problem

<< < (3/3)

rnolan:
I can connect to Presonus midi, just a bit a a fiddle with where things are...  I'll have a go at the re-seating chips etc tomorrow.  Still haven't heard back from Tim, hopefully he'll help.

MarshallJMP:
Ok the presonus should work fine, you can use bome send sx, a good and simple software where you can see what the mp-1 is putting out. You can also hook the midi out to the mp-1 and use bome to send midi commands, see how that works out. Since this is all in hex code you need to send (or recieve) 2 bytes, first nibble (4 bits) is "C" which is the code for program change, next nibble is the midi channel (0-F), 0 = midi channel 1, F is 16, next byte is the program change number (00-7F), 00 is program change 1, 7F is 128. Both the midi channel and program change number are off by 1, this is done to make it no so confusing for non digital nerds  >:D

So if you type in C0 00, this means program change, midi channel 1 program number 1. CF 7F program change midi channel 16 program number 128.

Hope this helps.
