Mouse help with OLA filtering
Mouse actions are quite similar to those of the Klatt synthesizer mode, i.e.:
- press the left button and the SHIFT key to draw a trajectory,
- press the CONTROL key and the left button to select a trajectory,
- once a trajectory is selected, press the CONTROL key and the left button to select other trajectories,
- press the CONTROL key and the left button where there is no trajectory to release trajectory selection,
- once
a trajectory is selected press down the CONTROL key and the left button
to move a point. Note that only the ordinate of a point can be moved.
