OB problem midi map Track on Analog Rytm

Hi there,

New AR owner here so please correct me if I say something wrong.

I’m trying to midi map the Track volumes on my Analog Rytm to the faders of APC40 through overbridge to be able to do some fade in / fade out effects…

So I’m using the AR plugin in Ableton, I click configure and select the track volume. Then I midi map it to my controller.

Now the problem is when I move a fader on the APC both Track level AND Amp volume are moving at the same time (in OB plugin and on the machine)…
It’s even more weird as the Track value moves first and the Amp volume seems to catch up half a second later…

Is it a bug or am I doing something the wrong way ?
