The "T" function now creates TimedEvents with LinearBlenders for you The "T" function now creates TimedEvents with LinearBlenders for you (using the same LinearBlender). Thus, we don't need to specify linear anymore. The timeline seek bar was reading the length of track1 instead of the whole timeline. This is fixed.
