Folks-- I need some help and I am coming up short on my research. I
work at a high school where we use a lot of wireless mics, usually
around 20. We have a difficult time tracking folks as they go off and
on the stage, and we don't want the mics muted. So, we've decided to
look into the possibility of purchasing a digital mixer. What we need
is a mixer that is great at playing back presets with the touch of a
button- and preferably in software. We would typically have around 100
"cues" a show. We would need 18-20 mic inputs, although our mics have
line level outputs as well. The ability for expansion would be great--
up to 28 channels. And of course the most important consideration is
price. We can't break the bank on this one. The one feature I am most
confused about is the memory, because in the specs it seems rather
obscured. Can you help? What would be the best mixer for this job?

Thank you!
