I would simply like to see the sliders on the touch screen display actually be movable with your fingers (and large enough to work with).

I think that Korg PA2X Pro's B3 section can do this (correct me if I'm wrong), so I don't see why this could not be used on ALL slider functions....

This would solve ALL the problems... Want a 'jump' to a new position? Just tap at the new position. Want a smooth move from the initial position? Start from there...

This all seems so obvious, it's a wonder no-one has implemented it in an arranger. yet...
