I somehow managed to get my Kontrol MK2 S61 and KK in a mode where each time I select a track in my DAW (Studio One), I must first change the default "Direct Input" setting to something other than "None", or else my Kontrol S61 will not play anything.
But, I also have to make sure that all other virtual instruments used on that song have their "Direct Input" settings set to "None", or else my keyboard will play multiple instruments when the keys are played.
So every time I switch tracks in my song, I have to manually "turn off" one instrument and then manually "turn on" the other instrument.
This happens when I play Presonus virtual instruments also, not just NI instruments.
How do I return my system to a state where my keyboard will play the instrument that is currently selected, but only that instrument? I have been changing MIDI and audio settings trying to fix other problems, so I'm guessing that it's something I did. Thanks!
