Error Messages
"RECEIVE ERROR" - This message will appear on a receiving Intellifex XL if Check Sum bytes do not
match, or if a status byte (MSB = 1) is received when a data byte was expected. This message
also appears if a knob is turned or a button is pressed during reception. This message also appears
if System Exclusive strings are sent too fast, without a long enough pause between strings.
"DUMP ERROR" - This message will appear if MIDI Data is received at the MIDI IN while dumping is
in progress.
"XMEM ERROR" - This message will appear if received data can not be verified after it is stored.
