NI 4control midi controller

Hello,
I own a Native Instruments 4control midi controller...the output of the controller is always 64...when I turn my endless knobs it changes that value to 63 (-1) if clockwise and 64 if CCW (+1)
Is it possible with midi-ox 2 convert these these parameters?
As far as I understand these values are put in nrpn 98 and 99?
anyway, I'm still a newbie :p
Thanks in advance for ne help !

I am not familiar with the 4Control, but the thing to do is to connect the device to MIDI-OX and then wiggle the knobs, to see what data is sent. Once you're familiar with what it's putting out, it should be fairly straightforward to map that to something else.

Same Kind of Problem w/ Studiomix

The Studiomix rotary pots work similarly. Take the NRPN pot at 1500; turn it left a notch and it puts out 16383 (another notch, the same again); turn it right and it puts out 1 (again, the same per new notch).
I'd like to map this, say, to CC 40 within a range of 0-127, incrementing/decrementing 1 per notch. Is this possible somehow (with "Map NRPN Data Increments" checked)?
I don't understand the "Map NRPN Data Increments" actually. Is it involved here?

Here is a VBScript that does just what you want. Incidentally, turning control knobs faster can generate increments and decrements larger than +/-1. Also, an increment is represented by *65* or more, a decrement by 63 or less.
This example illustrates how, via scripting, you can turn relative into absolute values in MIDIOx with VBScript.
---
' 4Control rotary encoder conversion script -
' endless rotary encoder relative values [incl. multiples] to normal CC's
option explicit
dim mox, num(4), ctrl
const BANK = 8 '# of 1st CC in 4Control rotary encoder bank
const NUMBER = 4 '# of CC's in 4Control encoder bank (max = 4)
const STEPS = 48 '# of steps to comprise 0-127 range
'48 steps = one complete dial rotation
Set mox = WScript.CreateObject("Midiox.MoxScript.1", "Sink_")
mox.DivertMidiInput = 1
mox.FireMidiInput = 1
Do while mox.ShouldExitScript = 0
Loop
mox.FireMidiInput = 0
mox.DivertMidiInput = 0
' Exit Point
'------------------------------------------
Sub Sink_MidiInput( ts, port, stat, dat1, dat2)
If stat <> 176 Then
mox.OutputMidiMsg -1, stat, dat1, dat2
Exit Sub
End If
If (dat1 < BANK) Or (dat1 > (BANK + (NUMBER -1))) Then
mox.OutputMidiMsg -1, stat, dat1, dat2
Exit Sub
End If
For ctrl = 0 to NUMBER - 1
If dat1 = BANK + ctrl Then
num(ctrl) = num(ctrl) + ((dat2 - 64) * (127 / STEPS))
If num(ctrl) < 0 Then
num(ctrl) = 0
End If
If num(ctrl) > 127 Then
num(ctrl) = 127
End If
mox.OutputMidiMsg -1, 176, BANK + ctrl, num(ctrl)
Exit Sub
End If
Next
End Sub
