So the manual was corrrect and not the tech note…”
Basically, you converted the decimal CC value of 8196 to binary 14-bit
and then separate it into two separate 7+7 bit values (MSB/LSB)

8196 (dec) = 10000000000100 (binary)
MSB=1000000 (first 7 bits)
LSB=0000100 (last 7 bits)

convert 7-bit binary back to decimal values:
1000000=64
0000100=4

MESSAGE FORMAT:
CC:    99
MSB: 64    NRPN 7bit
CC:    98
LSB:  4      NRPN 7bit
CC:    6
MSB: 0      data value 7bit
CC:   38
LSB:  0/1   data value 7bit (bypass/non-bypass value)

Fun stuff… 🙂
