Bind function to midi controller issue

as clearly as I can explain this. So when i bind function to my midi controller, what happens is not only when i hit the one midi note to trigger the chord, it also plays the same midi note when i press it to activate that particular chord, even though that key is not in the chord. and so it sounds crazy because its recognizing the midi key im pressing like its a part of the chord. I hope I made sense lol!

The Devs really need more info here -
What Controller?
What DAW?
What OS?
How are you setting up the Controller?

This has cropped up before and it is usually a MIDI message sending to ALL tracks. But any info you can provide would help.

Maybe your midi controller is passing on that note info. Have you tried turning ‘Local off’ on your midi controller?
