I'm actually thinking about purchasing a Tyros. I like the sound quality from demos I've heard, but I would really like to get my hands on one first. I'm professional, to the point where I make my living performing and producing and have had minor radio success. I've never used an arranger up to this point, and I stilll probably won't use it for the majority of my work; the sounds yes, the styles no. Even the styles will come in handy though for instant drum loops for helping to create ideas and sketches. Plus it would be a handy tool when I'm hired to do a cheap production or if I can't be in the studio at all, so at least the performer can get some semblance of accompaniment without me spending days on it.
