-Connect an LFO controller to the AFP loop- endpoint

Research direction

Start with the AudioFileProcessor entry point and reproduce the crash by connecting LFO controllers to the loop startpoint and endpoint, then changing one LFO's speed to create a collision. Trace the collision handling and verify that the same setup no longer crashes LMMS.
