Digitakt II: FX control via MIDI CC not working

Hi all,

my Digitakt II just arrived (updated to 1.01) and I´m already preparing it for a few upcoming live performances. It stumps me though that I can´t get the FX control via MIDI CC to work - control works fine for individual track CCs though.

I set the fx control channel to 16 and try to control the master overdrive (CC 17) with the Faderfox EC4 that is hooked up. But: Nothing - other master fx parameters (ie compressor) don´t react either.

Am I doing something wrong (I am sure it worked on my old DT) or is that an issue?

Thanks!
