We've been changing songs super-fast lately, so I picked up a Selah Quartz V3. I'm surprised it's as capable as it is. Simple interface but almost does too much! Also I might have messed up my number 1 slot, I was goofing off trying to figure it out without the manual and now I can't get the 1 slot to save with a name. If you try to put in letters, nothing happens. Anybody know anything about this? If nothing else, it can just be a tap preset instead of tempo/program like the rest of my songs. Just know it's always going to bug me when I start making setlists!
