// As the MIDIClientCreate docs say (https://developer.apple.com/documentation/coremidi/1495360-midiclientcreate),
// notifications will be delivered on the run loop that was current when
// Client was created.
//
// In order to actually receive the notifications, a run loop must be
// running. Since this sample app does not use an app framework like
// UIApplication or NSApplication, it does not have a run loop running yet.
// So we start one that lasts for 10 seconds with the following line.
//
// You may not have to do this in your app - see https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/Multithreading/RunLoopManagement/RunLoopManagement.html#//apple_ref/doc/uid/10000057i-CH16-SW24
// for information about when run loops are running automatically.
