I was just browsing this forum out of interest in eDRUMin and happened to recognise my writing in one of the quotes from the OP.
Very pleased to read that such attention is being paid to this hi-hat issue on here. You seemed to have coined it; Hi-hat (pedal) crosstalk? I also think this best describes the function we are looking a trigger module to cure... in short; a smart algorithm implemented on the trigger side to remove transmutation artefacts. As it's been correctly pointed out; VSTs don't seem to offer much in the way of finding a solution to this when "normal" drum modules have accounted for it.
So from the last few pages, I learn't that the issue isn't necessarily affecting all hi-hats - which makes perfect sense - prominently, we are mostly looking at any hi-hats where the trigger pad clutch is in direct contact with a motion controller, e.g. VH-10/11.
The data Rob collected also interests me; that it shows not only what I expected to see; the CC data fluttering with stick play, but what I did not expect, actually bouncing upwards too!
I previously suggested removing the transmitting of CC data during downward motion, and leaving upwards motion alone as a potential fix - but it looks like you might have worked out something better.
My only concern was not just adding a simple delay on reading on CC data after a note (to ignore movement for say 50ms) as that would introduce so much lag that it would spoil the point of transmutes in the first place - the key moment where you need it for natural hi-hat barking, from a closed position, without having to lead ahead of the beat with your foot to account for the flaws of most e-drum hi-hats.
Interested to see how exactly it works, hopefully in the not to distance future.
