I've just started using setups in my PC3 for live gigs & I'm using the sliders as volume controllers for each zone so I can adjust in real time on stage. Unfortunately the sliders don't seem to work on volume for the KB3 organ zones even though I've set the slider control to Volume in the edit section. Can anyone shed any light on why this doesn't work and if there is a work around what it is? (I've got the KB3 organs in zone 1 as recommended on the kurzweil site)

Thanks
