Filter does not work on individual stems.

Hello,

I use Traktor 2.11 under Win 7, and I am battling with the problem, that the filter is not working on individual parts of STEM files.

I use a Behringer CMD LC-1 to control the STEMS. I have created the mapping myself. It is downloadable for free here at Traktorbible. The mapping itself works fine, and there were no issues when I was using it in combination with my S4, as I still had it.

Now I replaced the S4 with the XDJ-RX from Pioneer, which covers (in MIDI mode) all features I need to control Traktor (I use the single license). It also provides a 4 channel audio interface, which does a great job sending the separate signals to master and headphones.

My only problem is, that there is no audible effect, when I use the filter on individual STEMS. The encoder display shows that I move the knobs, so I am sure it's not the mapping. Also, the volume control works fine. (I did not test FX sends, yet.) I was assuming this issue would be the XDJ-RX audio interface (ASIO driver), but I have the same issue, when I use the internal Sound of the laptop (Lenovo T420).

Am i missing some setting to activate the filter? ... or does this only work with the S4 interface? ... or did I discover a bug in the 2.11?

I was battling with this for several hours. Google did not find anything which worked. I messed around with ASIO4ALL, which was a dead-end street and was causing more problems than it solved.

Help in this case is highly appreciated.

Thank you!
