rpn 2 cc I'm totaly confused

Hi
I read the mapping questions more and more time , but I don't know how to map a rpn controller to a normal cc. I want that controller sends cc#3 with values from 0 to 126. I hope someone can help me.
Thanks
kotto
Here is the log:
B0 65 00 1 --- CC: RPN MSB
B0 64 01 1 --- CC: RPN LSB
B0 06 01 1 --- CC: Data Entry MSB
B0 65 00 1 --- CC: RPN MSB
B0 64 01 1 --- CC: RPN LSB
B0 06 02 1 --- CC: Data Entry MSB
B0 65 00 1 --- CC: RPN MSB
B0 64 01 1 --- CC: RPN LSB
B0 06 03 1 --- CC: Data Entry MSB

OK. I'll try to explain how I go about setting this up so next time it's not too hard.
We want to map the NRPN with MSB = 0, LSB = 1 to CC = 3.
First we open the NRPN calculator to get the full NRPN parameter number (View | NRPN Calculator...):
MSB LSB NRPN
0 1 1
In this case the parameter still equals 1.
Now we open the Options | Data Mapping... dialog to enter a Mapping, and press [Insert]
we enter the following:
When input matches:
Channel Event Min Value1 Max | Min Value2 Max
Any NRPN 1 1 0 16383
Set Output to:
Channel Event Min Value1 Max | Min Value2 Max
Match Ctrl 3 3 0 127
Notes: The full NRPN parameter is 1 as we calculated earlier. The NRPN value to be mapped is between 0 and 16383 because it can be a 14 bit value when both MSB and LSB of the Data entry controller are supplied (even though we are only receiving the MSB in this case). The target is CC 3 which can have a range of between 0 and 127.
After Pressing OK this all looks like:
* NRPN 1 1 0 16383 | * Ctrl 3 3 0 127
And we check none of the check boxes in the bottom of the translation map.

Hi Jamie,
thanks for the quick answer. I think I'm understand the rpn a little bit more. But your solution dont work in my system.
e.g.. The first mapping work, the second do not.
* CTRL 7 7 -1 -1 | * Ctrl 1 1 -1
-1
* NRPN 1 1 0 16383 | * Ctrl 3 3 0 127
In the monitor output the items are all the same when I move the slider wich produce the rpn.
thanks

I screwed up. I misread everything that said RPN as NRPN. There are only 2 RPNs defined for MIDI: Bend Range and Tuning. There is no way to directly map a RPN into a CC in MIDI-OX at this point.

We'll add this feature (Mapping of RPN's) for the next release.
