I can understand why you liked them, Chony...I really found them convenient for programming.
I did find them awkward when trying to move more than one...not as easier to grab as the physical "drawbars" I was used to on my Hammond.
I think Nord has the best compromise of all with the Nord C1 organ...visually available all the time...much better (and probably more reliable)than faders and wheels which can get dirty over time.
