Basically if I have the morph at a certain setting, it will change the active sound to it.

For example, if I have a snare at 100% and go to the bass drum (currently at 80%), it will sometimes, while I ma hitting the button, change it to 100% too.

I have had this problem since I got it 8 years ago. I thought it was intended but has become a problem when delving into mute groups, as a sound suddendly changing is not great.

I am not touching the back part.

Has anybody experienced this? How can I fix it?

Thank you!
