I'm having issues with my Midi THRU port on my kemper rack. Running the latest firmware 7.13. I am using a PC audio interface to send midi out to my kemper and a line 6 helix. connected as follows:
PC (sending CC messages on channels 1 and 2) --> Kemper MIDI IN (Kemper global set to 2, have also tried OMNI) --> Kemper MIDI THRU (set to channel 1) --> Line 6 Helix MIDI IN(set to channel 1)
With this configuration the line 6 helix is not receiving the MIDI CC messages from the PC (but it does receive the MIDI clock so I know the port is working). The Kemper receives the commands for channel 2 and processes them as I expect as well so I know the PC is sending out the commands. I have also tried flipping the order of my devices (PC-->Helix-->Kemper) and this works fine, both devices receive their messages as I would expect. Ideally, I'd like to have the Kemper connected to the PC directly and use the THRU as this will save in live midi cable routing.
Any help would be appreciated.
