Hi Mike,

as in Vince's example, you should be able use the set_fraction field
of the interpolator as attribute.
InterpolatorNode.setAttribute('set_field', newValuefromSlider) should
work.

It might work to use a timesensor's fraction_changed as an _offset_ to
the last position of the slider when the play button was pressed.

This probably means that the startTime of the timesensor needs to be
reset to now each time playing begins after scrubbing.
