When I want to practice using the left hand or with both hands by pressing the Select Part button, the left side of the keyboard would be completely mute when i press Lesson Lite or the play button. This only happens when I press those buttons, otherwise it sounds just fine. If I press Select Part so that I practice with the right hand only, it also sounds just fine.
I was just wondering if there was something wrong with my keyboard and if there is something I could do to remedy it, so that none of the keys go mute on me when I press Select Part and then Lesson Lite.
