Thanks Jason. Now I understand the returning of number of clicks per second, is there a way of commanding a button to act as Button Hold instead of just a Button Press with immediate release? I understand the onHold and onHoldInterval functions but I want to mimic a button to be held which in turn will mimic the use of the iPod scroll wheel.

To answer your PS: The Yamaha takes control of the iPod but I don't think the iPod can be controlled indirectly using RS232 when attached to the Yamaha Dock.

Regards,
Matthew
