Yes,I too was taught not to sit too low (like Glenn Gould), play with flat fingers (like Vladimir Horowitz), or rock my body (like Stevie Wonder), but hey, these guys still seem to make beautiful music.

The pics may not show this clearly, but I'm actually 'standing' most of the time while performing (to maximize diaphramatic breath support for singing). I utilize a 'high' stool primarily to provide body support 'while shifting my weight between' my right and left leg in order to trigger the left/right foot pedal controller. I dunno about you guys, but the keyboard height & playing position I use works best for "ME" ! I experience no back, neck or shoulder pains. Maybe it's because the PSR2000 weighs only 23 lbs.
