Vibrato...nice to have it variable as well as on/off...Leslie speed(variable) and yes, filter cutoff...real cool with the wheel...better than sliders IMO...your hand is already at that end of the instrument.

I like the strip too...it was on the Yamaha CS-80 and my old Polymoog...still, I do prefer the wheels...just seem more natural than the bender....awkward pushing ahead and sideways at the same time....yeah...wheels are better.
