Actually one of Kornel script "side" feature is "Full Piano Release mode" (called "release mode"). But Xavier's script behave better for this particular feature (despite a probably a less CPU efficient algorithm). Kornel script's fade out notes in "release mode" are less natural (linear decay).
The fact is, both script are compatible and could be used jointly (do not activate Kornel "release" button of course). Kornel script still manage a "half pedal down resonance" even without the release mode engaged !
I do this for some not-to-big-pianos that works best with only PU samples + kornel full approach for PD resonance (like The Emperor). Both script can run together without pb.
Could somebody explain me what is exactly "half pedal". If I want to use Kornel's and Xavier's scripts together, which should I place first? Appart from disabling the release butom from the Kornel's script, should I enable/disable anything else?
Half pedal is the half damping zone of sustain pedal.
To experience that you first need to have a progressive sustain controller (not only a switch).
About using both scripts, I would say it's useless if release mode of Kornel script already please you, the difference is quite subtle. But if you do that, you must load first Kornel script (release mode off) and then Xavier release mode script.
