[Doggiebox] non accessible drumhits

Hi folks, I'm struggling with the following problem: - Song: 4/4, 135 bpm - drumkit: Ludwig V2 I can't see and edit some of my previous inserted drum-hits because the maximal zoom stage seems not to be enough for viewing/editing them. I can see the grey squares indicating that there's something but can't access them. I created the stuff a few days ago, wanted to go on yesterday - with no luck. What am I doing wrong? Bye Thorsten
