The events from here should be read by the corresponding track processor's MIDI in port (TrackProcessor.midi_in). To avoid having to recalculate the graph to reattach this port to the correct track processor, only connect this port to the initial processor in the routing graph and fetch the events manually when processing the corresponding track processor.
