I think that would be useful if we can trigger a video clip via midi something like the piano style,
but with a control of his behavior in relation to the transport of the clip.
Something like audio samplers and adsr envelopes.
For example we could insert cue points marking the length of the (A)ttack section,
the (D)ecay part, the Sustain and the Release.
Then the sustain part could be looped until the note off, activating the release section of clip.
