I have created a Kontakt 16 output track and linked 4 instruments to a different MIDI channel, i set these channels to 4 different MIDI tracks through the inspector.
All worked until i accidentally clicked on the channel button on the track, the one with a number inside, as clicked on it all the MIDI channels were changed to the same one!! Why!? How can I solve it??
Are you selecting the four tracks, see to that you select just one.
If you did a quick link group while pointing them to the same instrument - would also make them work as a group.
If that quick link is still active, I mean, disengage it.
