Digitone ext MIDI > TN > MIDI Out

Hi,

I am going soundcard MIDI out > Digiton MIDI in. I have MIDI channel going 1 -4 and FM channels 5 - 8.

I can’t seem to set soundcard MIDI channel to 1 and send the midi info to the Digi and have the Digi send that info out. I can do this on the Digitakt, am just wondering what is different here…
