On most of the Kross 2 acoustic piano programs, a knocking/tapping affect is added to the pure piano note to (I guess) simulate the percussive sound of the piano's action. Typically this effect starts higher up on the keyboard, since the sound of the action is more noticeable as you go higher in pitch. For instance, on Grand Piano 1, the effect starts rather abruptly at G#5, and IMO is way too noticeable. I certainly hear nothing like it on our baby grand. It has to be under software control since if you switch the keyboard up an octave, then the effect moves "physically" to the left on the keyboard. Also, it sometimes starts at different pitches and intensity depending on the specific program. For instance, it starts at F#6 on the fortepiano program. I looked at keyboard track and note hold, which are the only two parms I could see that can be programmed by range, but I believe I understand what those parms do, and neither seems to affect the knocking/tapping sound. Anyone know if there are user accessible parms that allow adjustment of the starting pitch and/or intensity of this effect?
