The MKConductor Class

• The MKConductor class is the primary performance class.

• Allows you to schedule an Objective-C message to be sent in the future. Example:

  [aConductor sel: @selector(hello:) to: anObject atTime: 3.0 argCount: 1, anotherObject];

  At time 3.0, aConductor will send:

  [anObject hello: anotherObject];

• A MusicKit performance requires a MKConductor. You need not create a MKConductor explicitly. A “defaultConductor” is created for you and is obtained by:

  [MKConductor defaultConductor];

• Multiple MKConductors may be used. Each may have its own tempo and may be paused/resumed independently. However, the entire performance is controlled by the MKConductor class. E.g., to start a performance, you send:

  [MKConductor startPerformance];
