Midi modules

so is there an issue with using multiple MIDI modules at same time?
it seems when i assign 1 MTTR & 1 MTIN module (and 1 MTMO for monitoring, which works awesome)
only 1 of these modules can work with the current INPUT/USB interface)

or should both modules work simultaneously?

i need to unplug my MIDI connection everything i want to use either of them

(it is or generating triggers from note one, or sending MIDI cc, although i have to admit i cannot have MIDI cc working/controling any parameter - CV working fine though)

edit: nevermind, got it working with re-assigning all MT modules in the patch
would be nice if we’d see (something) incoming in the MTIN module though

edit2 i whish there was a way to go below 0 with MIDI input (as in-5-+5V)
