RPNs and NRPNs
RPNs (Registered Parameter Number) and NRPNs (Non-Registered Parameter
Number, or as musicians like to call it, “
nerpins
” when they want to sound cute
instead of nerdy) both work in the same way. RPN’s are specified by the MIDI
standard, and NRPN’s are specified by particular manufacturers. Refer to the
manual of the device you are using to understand how it uses NRPNs in its MIDI
mapping. RPNs and NRPs are just like standard MSB and LSB commands, but are
set up using other CC commands than CC:0 and CC:32.

How to Use NRPNs
Refer to the manual of your MIDI device to see if and how it uses NRPNs. The
most typical method is by activating two CC commands to be treated just like a
bank MSB and bank LSB. These can be set to a range of parameters on different
devices. One example is how the Singular Sound BeatBuddy sets the tempo.
Please note that the BeatBuddy's song does not change until the Program
Change message is received, i.e. bank messages alone are not enough to
change a program.
We know this is confusing — but MIDI was designed by computer nerds, not
normal people like us, and computer nerds like to start with 0 instead of 1.
