Sequence Controller

Two data points, one with value = 0.0, t = 0.0 and the other with v = 0.0 and t = 0.5.

The result of a "Sequence" is one float value which changes over time.

Move a point, left-click-drag it around
To insert a point, hold shift and left-click
To change interpolation type of one point, right-click on a point to bring up the menu
To enter value manually, select it from the right-click-menu. Type in the new value.
To enter time manually, select it from the right-click-menu. Type in the new time.

Hold down [Ctrl] to mirror/straighten the handle of the previous bezier section. Does only work if the value you are changing and the previous have bezier interpolation.
To ensure that the first and last value is the same if both are beziers - to create seamless loops, hold down Ctrl+Alt+Shift after you have started moving the point. The corresponding point will follow. This also works when editing the last point.
