Eileen, I find the sliders don't work like sliders on a mixer. The Genos sliders need to be "activated" before they'll change a setting. That is, you need to move them a fair amount before they change a parameter. By the time you move them, you may have over or under shot the original setting by too much or too little. VERY annoying!
I just finished a big Christmas show last night - over 400 people. I was the primary musician with my Genos, backing seven singers. I was using the Multipads and found them a little soft during a song. When I tried moving them up a bit, the lag caused me to overshoot the desired volume. I then had to bring them back down very fast. It was only for a split second, but very annoying! Try getting that right while playing live!
I wish we could set them so they would just move when we move the slider, just like on a mixer. Don't know why Yamaha chose such a stupid architecture! I submit that using the sliders to change the Song volume would be cumbersome and very dangerous at best.
