Hi Kroes and Rounik,
Kroes, the above reply by Rounik pretty much sums it up. The only thing I could add is to say that when you select the text you wish to edit, you will see a slight change in the inspector. With nothing selected, one of the right pointing triangles at the far left side of the inspector says 'Insert Defaults'. When you select text in the score, that will change to 'x Texts selected' with x being the number of text items selected. Clicking on that triangle with the desired text selected will open up a box with the various parameters available to change and move the text the way you want. Not sure why you are not able to print so that exactly what is on your page view in the score editor doesn't come out of the printer when you print. It should, and maybe Rounik's last two questions will help you there.
So, Rounik, yes, as far as I could see, the score editors in LE8 and LP8 are identical. I did not do an exhaustive check by any means, but a thorough perusal of the features of both seem to confirm this. I also followed everything that Steve H. was doing in his score editor TNT, and LE8 and LP8 matched in every instance.
As for MainStage, yes, it was a pretty big part of my students' last show, along with Logic. I will try to post in the MainStage forum more info on this, as well as some other stuff, too. Thanks for asking, and I'm glad you remembered.
