Any NRPN-headz out there?

[rozze]

I want to control my Rozbox with my BCR2000. The CC's cover only half of the Rozzbox's functions, but the Rozzbox can be almost fully controlled by NRPN-messages. The NRPN-chart in the Rozzbox's manual gives you four attributes for each parameter. Here's an example for the parameter "Filter 1 Cutoff":

NRPN MSB #99: 0
NRPN LSB #98: 25
Parameter: Filter 1 Cutoff
Value: 0-255


The BCR2000's menu for a NRPN-control-element consists of 8 attributes (of which only the red ones are important right now):

MIDI Data Type (must be set to "NRPN" obviously)
MIDI Channel
NRPN Parameter Number
Min. value
Max. value
Controller Mode (bit resolution, must be "14bit" for NRPN obviously)
Controller Option (just LED behavior)
Display Value (just LED behavior)

The Min. value and Max. value of the BCR2000's menu obviously correspond to the Value range in the Rozzox's NRPN-chart. BUT the NRPN-chart gives me two further numbers (NRPN MSB #99 + NRPN LSB #98), whereas the BCR2000 asks only for one number called NRPN Parameter Number.

So, if I want to assign a knob of the BCR2000 to the "Filter 1 Cutoff" of the Rozzbox, how do I know what to enter as NRPN Parameter Number?
