defer De-prioritize a message When Overdrive mode is enabled, objects such as metro operate at interrupt level. This locks out other processing from happening, which may affect timing performance. If you want to execute a time-consuming task, such as using an Uzi for repetitive operations or the bang message to a table object, you can defer the interrupt level output to the lower priority main event level by passing a message through the defer object.
