tom you are correct, I actually figured that out at tonights gig.. i re-mapped my preset as well to fix the issue, but strange how even after changing the preset and re-mapping the upfader it still sends a cross signal.. So i have now just cleared that preset channel 10 to empty.. i will do some work and research on it over the holiday and see what i can figure out.. but i don't miss my 62( even tho from the start it had zero issues), I still like the extra features, feel and layout of the s9 as well as the total sound output better for sure
