Sub 37 NRPN values and (RESERVED) and Hex

* NRPN - how can VALUES be entered? eg the MOD WHEELis CC99=3, CC98=18. so which two CC’s does the 16384 VALUE RANGE go into?

  • What are the mysterious (RESERVED) NRPNs? There seems to be a lot. Are there extra features in there? Can I brick the Sub 37 accidentally by poking around them?

  • A MIDI-OX tip - to switch the monitor output from Hex to decimal (discovered this after hours of converting with a Hex Calculator)
    Go to Options => Data Display => untick Monitor Input: Hex

To send the value in full 14 bit depth, you have to send these four messages (CC numbered in decimal values here):

To select the NRPN parameter you have to send this (see table in the manual NRPN):
CC #99 = 3
CC #98 = 18

To send the values of the just selected parameter send this (always exactly these CC numbers):
CC #6 = sends the MSB (the 128 course values = normal 7 bit MIDI depth)
CC #38 = sends the LSB (the 128 fine values added to the MSB value)

These “reserved” NRPN might be used (or not) for future features. If poking actually do a thing to the synth depends on the work of the developers. The synth might crash, do nothing, or change something. The “reserved” is just tells developers of software for the synth to not use these for other tasks. There are plenty synths out there that never used a single of the reserved parameters.
