DATA ERROR
MESSAGE
EOX
NOTE:
1. Data error message is sent if there is a check sum or-
ror during memory load. Error message (FOn, 42a,
21x, 01a, 20a, F7x)
2. The request sent by the computer must be: F0x, 42x,
21x, O1x, 10x, F7x (wher€ "H" means hexadecimal).
Memory data is then output in the order: FOa, 42a,
21x, 01x, rTl€tTlor! data check Sum, F7n -
2 Reception data
Channel Messages
NOTE:
lf received data is outside of this range, it will be trans-
posed to nearest note of the same name.
3. Negative numbers are ignored.
4. OMNI ON/OFF is always interpreted as being accom-
panied by POLY-ON.
Separate POLY-ON or MONO-ON messages are
ignored,
5. ppppppp = 0 - 127 (PRoGRAM NUMBER)
However, if number exceeds 63 then subtract 64 to find
value as interpreted.
Example:
74=10
&=0
6. VOLUME CONTROL:
vvvvvvv =7F, is the loudest volume. Volume
decreases as value approaches 00x.
