Non-registered parameter implementation in the 300 allows all public system 
parameters to be controlled. The smaller packet size of these messages, as 
compared to equivalent SysEx messages, make non-registered parameters a 
more efficient means of system data transmission.
When Auto Mode is set to NREG-PARAM (in Control Mode), changing any 
public system parameter will transmit a running status MIDI controller message 
formatted as shown below. Note that Lexicon uses:
• nrpn MSB messages (63) to send 300 Domain ID
• nrpn LSM messages (62) to send 300 parameter numbers
• data entry MSB messages (06) to send coarse parameter values
• data entry LSB messages (26) to send fine parameter values
