If the keys are assigned to the chords, you can play the chords with these keys.
All other keys can be played as usual. If the scale corection is turned on, they will be pitched to the set scale.
The “Master Trigger” function is another way to trigger Chords.
If you activate the “Master Trigger”, you can map a midi note
If the Midi Note is played, it will always trigger the last chord.
This function is cool to work with midi clips, to have always the same rhythm structure, while you can change the chords on the fly.
