Model S & mmMidi to CV Interface

Hey guys,

i’ve been looking for an answer on this forum but did not find any yet.

My goal is to trigger my Eurorack BD9 Drum with the Model S.

Model S goes midi out to the ALM Busy mmMidi to CV Interface. Like in the video below shown you have to setup the mmMidi by triggering 3 different Midi Channels on the Model S. This is where i cant get it to work.

Anybody has a similiar setup maybe and knows how this works?
