Hi, I just made an 88 knob layout on an iPad Air 1, iOS 10.3.1, & there is lots of lag. When I turn a control it jumps around skipping values, then after a few seconds it becomes smooth, but this happens whenever I turn a new control, so persists. MD is the only open app. I tried restarting the iPad to see if that'd help but it didn't. I even sent it to my iPhone 6S+ even though it wasn't made for its small screen, but it was laggy on that too. I'm going to attach the layout for you to test...it shouldn't be so laggy right?
