Diki, as I mentioned the hold /sustain pedal can be turned on/off for each section..lower or upper..
It is the simplicity that warrants the A33 as a good controller for a GS instrument..
I have used the EMU extensively..4 zones etc..it is a great controller, but for use with the G70...I prefer the A33..
I do like and miss the USB powered feature..and USB midi...but with the USB /midi interface ..the A33 is okay..
