I guess I'm among the fortunate individuals that never experienced a keyboard failure, though I did have an amp drop dead during a nite-club job in Baltimore.

My backup keyboard is identical to my primary keyboard, and every registration, user files, etc... are identical as well. My NYE jobs are 20 minutes from the house and if one dies, which has never happened, I can be up and running in about 40 minutes. Or, I can just finish the night using MP3s on the laptop and DJ the remaining time.

Cheers,

Gary
