Hi George, I have played with the Tenori-on for a few hours. It's a very sexy and attractive piece of gear but I did not fell in love it with, mainly because of the el-cheapo sounds. In addition to that, it's a totally different concept compared to synth and regular sequencers, I didn't have enough time to really understand it. My 2 cents ;-) For more info, check out the SOS review: http://www.soundonsound.com/sos/feb08/articles/yamahatenorion.htm -- Sjaak Overgaauw http://premonitionfactory.com/ http://livelooping.be/
