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.
