Suddenly I cannot use the drummer feature and I can't figure out why. When I start a new project the drummer track option is greyed and even when opening older projects the drummer track shows and is audible but I cannot see the "drummer", nor can I change "drummers", etc. This is very strange as nothing has changed on my system or software. If anybody has any thoughts or a fix I'd appreciate it very much. I'm on a MacPro tower - Logic Pro X 10.0.4 screen shots of missing drummer and drummer track option greyed out
