I stood up for over 25 years,then I got lazy and started to sit for a few years while performing but if you gig as much as I do many times 2X a day my arms would start to hurt due to sitting back and extending your arms to the keyboard. This past Xmas I got together with UD and we reconfigured my setup from top to bottom and now for the last few months I have been standing on stage and Love it. First of all your arm are straight down increasing the blood flow, you look better to the audience with a profesional appearance, your in better control of keyboard/equipment navagation, singing is easier, you can move and groove to the music while playing too, No stool to carry. I really like standing and IMO its the way to go for a professional looking performance with an arranger keyboard solo act.
