Has promise but poor documentation – DigiStix Drummer AUv3 Plugin Review

I paid for this app because it specifically states in the description that it allows for round-robin functionality. Although I found where to turn it on, there's no way (that I can find) to stack the sample layers to allow for this. And in the help section of the app, there's no mention of it. The 4pockets.com website appears to be from several years ago with absolutely nothing on there about this app. I wasted my money basically, unless someone can explain how to get round robin to work.
