Not for the moment, but you already follow this topic, that's fine ;)
I don't understand how it works exactly, even with the video. With the HAARP, the resulting sequence have a variable length, depending on MOTIF/RESYNC/LOOPS and the notestack length(10 notes Max), this resulting sequence(the full loop) can easily exceed 16 steps(HARPIE), so it's difficult to do the same feature.
But don't worry the velocity can be animated too, with the TARGET feature, and more precisely than a ON/OFF or an accent system, in my opinion, a little more musical yet.
