problem dialing in exact values on Voyager

Hey,

I often dont use the spacing parameter because I have problem setting it back to 0, its get either -1 or -3 or 1 or so on - or sometimes 0 4 -2 and so on.
Where can I fix this on the Voyager?

I also have stepping sound problems.. Is that because I view the parameter values on the display?

1 more thing: can I get a real mono output of all filters without physically unplugging the cable? I would like to be able to store mono output in the preset



Thanks
