@davide I’m familiar with using Keys-Lock when binding to chords in sections A & B, but what I want to do is set up a pattern in the tab grid (section C) and play a melody along with that. But I can’t find a method to use K-L in this way. Regardless of whether or not K-L is on (or in any of its modes) if the keyboard is bound to the grid, then a midi key event will only trigger chords on the grid. I thought perhaps the Chord Mute function would turn off the triggering of the chords so I could play melodies over the pattern, but that doesn’t work. ??
