No support of Chase Bliss pedals?

[radzmar]

I'm having a few effects pedals (Chase Bliss, Empress, Hologram), which are all MIDI-controllable., I'm not new to this: But, with the Chase Bliss pedals I have no luck when it comes to the MRCC. I'm using a MIDI-to-TRS-B-cable which works absolutely fine, when I connect the pedals directly to an Elektron Digitone, Digitakt or AKAI MPC One for example. Also when I'm using a MIDI-TRHU-port of the ASM Hydrasynth, Microcosm or even a passive MIDI-Splitter like MIDI Solutions Quadra Thru V2, the Chase Bliss pedals do, what they are supposed to do, except with the MRCC. Attached to it MIDI won't work at all. To me it looks like something essential for those pedals is filtered out by the MRCC. Any ideas?
