map cc using value of another

Hello,
is it possible to map a cc#1 to any NRPN and use the current status of cc#2 as value within the NRPN message?
If yes, how the hell?
If not, add it to the wish list

I'm not sure I understand what you're asking? Why would you need to use two controllers for a single NRPN? Why can't you just map CC:1 to a NRPN #? You'd choose which NRPN# CC:1 maps to and then the CC:1 values get mapped into the NRPN range. If I'm missing something please elaborate on your question -- what are you trying to accomplish?

I need a way to send way more than 128 different controllers (don't ask why or I will explain...) on one channel. I want to have access to _all_ these controllers by a 16Knob Doepfer PocketDial.
The PocketDial Data could be mapped by MidiOx, the mapped data will be received and recorded in cubase. Now, how may I use 16 different cc# to control a range of 128x16 cc# easily?
Well, the pocket Dial can send program change messages if I push a special button and move a dedicated knob. In MidiOx, the program number could be stored "somewhere". Whenever a knobs normal cc#0-15 is received, I could build up NRPN message with the controller number being (program number*16)+knob cc#...
Got it?

Well you could choose the NRPN number by the CC:1 by choosing "use input value 2" and mapping it into a range of 0 - 16383 and a fixed value of 0, and then map CC:2 to into the Data Entry controller. Once a NRPN value is set, the data entry values apply to it until the NRPN number changes.
Ex:
* Ctrl 1 1 * * | * NRPN 0 16383 0 0
* Ctrl 2 2 * * | * Ctrl 6 6 * *
Or you could build your own NRPN's by mapping controllers values into CC:98 andf CC:99. Just pick: "use input value 2". You'd also want to clone the original controller and have it issue a hardcoded MSB value in CC:99, and then map data entry MSB as above.

Thanks Jamie,
I'm unsure wether I didn't get _you_ or you didn't get _me_...
Maybe I should go a little deeper?
Assume I have 16 dials that each send cc values to cc#0-15.
I want to use dial#16, i.e. cc#15 to choose a "bank", i.e. specifiy a MSB of a NRPN#, each other dial's cc# should specify the LSB of the NRPN# and the cc value should be send to set the NRPN value...
Question: if a cc#99 is send specifiying the MSB of the NRPN, followed by a cc#98 to specifiy the LSB, followed by cc#6 to specifiy the NRPN's value and you then send _only_ a cc#98 and specifiy a different LSB. Would this still be a valid NRPN?
Guess it depends on the receiver, isn't it? What's the standard saying?
Thanks
TabSel

Well I think I get it now, and with careful mapping, I think MIDI-OX might too 
so... To map NRPN# 4236
* Ctrl 1 1 * * | * Ctrl 99 99 * * // MSB dial up (33)
* Ctrl 2 2 * * x | * Ctrl 98 98 12 12 // LSB hard code 12 and clone
* Ctrl 2 2 * * | * Ctrl 6 6 * * // CC:2 value maps to CC:6 value
Is that closer?

You're right about the receiver, and it also matters when the receiver was turned on (if it missed any data). A significant amount of gear would switch NRPN numbers upon receiving a 2nd different LSB. Most would cancel the NRPN number on receiving an MSB, and then wait for a new LSB. A recommended practice when you don't want the above behavior is to close the NRPN after sending it a full NRPN with data entry, by sending CC:99 127, CC:98 127
