Do I understand correctly that the engine state (Stopped, Running, Pause
etc.) is send to the plugings ising the TRANSPORT control?

In fact a Pause state is not needed if a control is available to indicate
shuttle speed/direction (eg. a float; 0.0 if in pause; 1.0 if normally
running; >1.0 for fast forward; negative for reverse scrubbing etc. This
makes the plugins aware of varispeed and shuttling from the host.

just a thought.
Frank.
