Fine Knob Motion for Configuring Multi's
 

Folks-
When setting up a multi via the hardware interface you've got to choose the patch and the key range by turning the assignable knobs. Since there are so many possible values squeezed into a single knob sweep it takes some effort to land exactly on 3-4 or B3. Does anyone know if there's a shift button press or something that slows down the knob speed or increases the resolution?
Alternatively, has anyone found a good multi editor?
Thanks,
