Thanks for that Summa, I will make sure I follow the GM2 MIDI spec from this point forward. Just think of it, the EX800 will actually be GM2 compatible! Also, I just fixed the modulation generator which had gone awry after I made the switch to the new EEPROM code. When you set the frequency of the MG, the CPU does a lookup into a table of values that are used to determine the actual cycle rate. Only problem is, the lookup code could not work across a boundary larger than 256 (8 bits) and when I relocated the code, what do you think happened but that the table ended up straddled across an 8 bit boundary (by amazing chance - I should buy a lottery ticket). This caused the MG to go up and down in cycles instead of smoothly speeding up as the MG value went up. I relocated the table back inside an 8 bit boundary and the MG is fixed. So now I retested my MG controller and it works great. So we now have three fully functioning controllers that the original EX800 never had.
