Amongst the "complex" scoring programs outthere, this is the simplest one.
I'm a computer engineer by school, but never succeeded in managing Finale! Sibelius is ok.
(I mean: the best program for a given purpose is the one where you have to dig the less possible into the manual, and this is one)
Due to the high price, I can't advise it for simple scores — my reference, there, is old Cubase 4.0 in OS9, and the closer to it is Logic, even if I cry everyday for the lost simplicity of my old Cubase... :-(
So there should be a Sibelius Lite for normal human beings who don't need to rule a philarmonic orchestra; us, poor composers simply can't afford those overpriced monsters...
Except for the price, it's a must-have.

Well, version 5 is not ready for prime-time. I've been a user for several years starting with version 2. Each upgrade up until v. 5 added features without adding significant bloat. Not so with 5: it's pokey to start up, sluggish on anything older than the latest Macs, crash-prone, and worst of all, they've changed drop-down menus and dialog box functions so that one has to do extra clicking with a mouse (excessive trips to the mouse was one peeve I had against Finale). I waited to review this as I wanted to give tech support a chance to help me resolve issues, but they've been unable to do much. I also was waiting for a 5.1 update that might address these nagging issues (I recall a quick release of 4.1 last time), but it's been several months since 5 was released. Now that the developers have a good chunk of the market share, I'm sensing the complacency that plagued Finale: new versions are bloatware that have a few features heaped on rather than being a more efficient tool for musicians. I may look elsewhere for my notation needs, specifically for a developer who is still hungry for market share!

Wonderful thing. It costs much, but it's worth the money. I used MusicTime for years, but I'll switch to Sibelius. It's really simple to create some sheets.
Thanks!
