Tony,
Not sure if it's posted on this thread or not but I use the
iKlip I mount it on a mic stand then position just to the right of the screen on the Tyros4 at a an angle. It's a very low key and could almost appear it's part of the keyboard. I have taken some poor quality lead sheets and used Sibelius Student edition to re-write the lead sheets. When using those the size works out much better. I'll shoot you an e-mail with a sample.
