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.
Mike.
