Or you could try just using less effects. :p But seriously, I use a BOSS Digital Delay too and I rarely change the settings during gigs (unless I need a specific ping-pong type of rythmic delay). I honestly think it's much more efficient to keep your stage rig as simple as possible, to avoid potential disasters. This means keeping your effects minimal. I only use a Crybaby and an Ernie Ball Volume Pedal between my guitar and the amp (and run the digital delay through the effects loop). That advice probably doesn't help you too much, but I find using less effects pedals makes life easier.
