Those XLR snakes are ridiculously expensive.
But they're the only thing you can get away with if you're planning on miking a band and mixing any distance away. I have a couple snakes, all TRS, one balanced, another unbalanced, and another is send/return... so basically a Y snake. Those were pretty expensive, but they're invaluable in a studio when you're using a mixer and any kind of hardware processors.

Now that you mention that Soundcraft mixer, I realize that you deal specifically in live mixing, which obviously needs nothing other than XLR inputs.
I think we may have been barking up the wrong, but closely positioned, trees.

Yeah, I thought that's what dude was talkin' about.

^And that's why I said XLR in my initial post. The OP was asking about gigs and all of the venues I've played at have used almost strictly XLR cables.

What I'm saying is, really, do you think a guy playing a Casio keyboard with nothing more than a headphone output and no technical musical knowledge, is going to be playing a gig at a venue equipped for bands that get a paycheck?

Man I've seen it all

I don't doubt it, but I guess I'm relying on a little common sense when it comes to me expending time and effort to help someone out.

Now if only the OP was audio-literate enough to clarify things enough to provide a solution to which of us wasted our time.
:D

Good save ;)

You're too old for my own good.

Hey, thanks. No need to step up my game as I'm just an amateur and despite the lack of output it is a really good piano.. plus I'm ridiculously poor and good electric pianos with proper outputs are ridiculously expensive.

Anyway, thanks for all the advice guys. I'm going to head down to the local muso store and work something out with all the advice from this thread.

Oh, and for the record I am a girl! :)

Again, I'm a girl, and I normally play on a real piano which should explain my lack of technical knowledge when it comes to electric pianos. I am not a professional musician, was just simply curious as to how I would go about hooking up an electric piano to a PA without a proper output. I'm used to playing 'analogue' so sorry for my unsound knowledge in the technical department!

Anyway thanks for all of your help.
