Reply to When midi controller or computer breaks down at the party...

I have a dilemma.
I have traktor S4 but friends say that I am a ninja because the controller s4 does not work without a computer and the error pops up at the party I cooked: D

That's why I want to sell it and buy something that will be more unreliable and not the computer I fall I will be able to continue to play the event.
I believe the Pioneer XDj-R1,

Do complicates too much?
I want to have a "fuse" when computer breaks down.

What do you suggest?
