ProppFrexx ONAIR User-Forum

I have configured a faderport 8 via midi and everything works fine except for one thing ...
The fader does not move properly, appears to be stepping in magnitude.
The fader in proppfrexx also remains stuck at 80% at 100% fader in faderport 8.
And also applies to fader on 0 = fader in proppfrexx 20%.

It seems that too big steps are being made in the midi steering.
Is there a solution for this .. I have done everything neatly through the tutorial and various topic stories.

By the way, I have the fader problem with icon and presonus so different devices.
Maybe this problem with the fader is normal then I can stop searching ..

Sounds like an issue with the high and Low value of the fader? Is the fader using values from 0..127 or from 0..16383?
Are you using the Auto Pair option?
And are you sure your mapping is correct and you are using the correct values? However, as I don’t know the Hardware, I simply assume an issue with the data value.

using values from 0..16383
auto pair = on

Maybe the Auto Pair option is is problem in your case?!
But you would need to consult the documentation of the MIDI vendor.

Best Bernd,
It took some searching, but by setting the faderport 8 to midi, everything now works super smooth.
Thanks for thinking along and thanks for your good work !!
Fader now works on 0-127 steps.
