One thing I can think of is to map the same midi note to the clip play direction buttons.
play forward: piano,
pause: piano, inverted.
This way a note will make the clip play for as long as the note is held.
Another way which would be essentially the same, bit more complex but more flexible, is to use Visution's Ir OSC sa
Plugin for which there is a 64 bit version that also works with Resolume 6.
You could also create midi note duplicates to the playhead, setting every individual position would make the playhead jump to the position, but this would not be smooth.
You could also use the Cue buttons which would have a similar result.
For smoother, Ramp up/down type pushes I think you'd have to look for a third party OSC or midi application.
