I have a keyboard setup using a keyboard, a sustain pedal and an expression pedal. An image of my keyboard stand is below for reference. I am having trouble finding a good position for the expression pedal, because my knee hits the stand when I put my foot on the expression pedal. I saw some images of organs with expression pedals, which seem to be a bit higher and more angled, than the usual floor pedals.
I think I have my keyboard and seat positions currently very similar to normal piano heights
Should setup my stand and seat different to fix this problem? Are organ manuals (and seats) higher than piano manuals?
