Then your MIDI implementation list is different to the one I found in
the Internet, since a dump request by this list needs different values
than those you used.

You send 44 00 00 for Casio, that's correct compared to the list from
the Internet, then you sent 70 for MIDI channel 1, that's also ok
compared with this list, but after that you sent 19, weil the Internet
claims it should be 10 to request a dump.

Than you sent 60, regarding to the Internet list its correct to request
the patch from current sound area.

You add two times 00, but the list in the Internet says that the ok
string 70 31 is needed.
