I also gig several times a week with my Tyros2, but have to concur with Diki on this one.

It doesn't make business sense to buy two of ANY keyboard, especially one that's expensive. Remember, there's equal chance the PA or mic might blow, the keyboard stand might collapse, or the gig venue power fuses blow. Does that mean we should buy TWO of all those as well, and how does that solve the problem if it happens ON the gig? I'm certainly not going to transport EVERYTHING in duplicate to every gig.

I think flexibility is what's really called for. Though (in nearly 2 years) I've not experienced a Tyros2 breakdown, I've still got my core backing tracks stored on my iPod allowing me to simply take my old Roland A33 controler & Alesis piano sound module if if that scenario ever comes up. That said, because of my own absent mindedness on the very rare occasion of simply forgetting to bring a key component (aka: KB/PA power cord, cable, etc) to the gig, I've had to simply play the acoustic piano, yet still gave the audience a very good time. In our excitement about the latest keyboards & features, let's not lose track of this fact: It's really about what we're able to deliver & entertain from our heart, and less about the actual keyboard/instrument used. - Scott
