Can I create a Fader for the Chords Track in the mixer?
No, I’m afraid you can’t, but I agree that one should appear if you have routed the chords to a specific channel on one of your plug-ins. I will make a note of this and we’ll take care of it in a future update.
I actually found a way. I assigned the chord track to the first Kontakt Instance, which appears as Kontakt Stereo output. However, it would be nice, to have an easier way. Volume of Chords is a function, I need quite frequently.
