I'm interested in a sleeker and faster score editing tool. I've tried Sibelius 5 but it's just overly bloated (why do I need video support, anyways?), Finale didn't quite gel with me.

I'd like to hear opinions from the people who tried Notion!

Ha!  I was looking at Notion 3 for exactly the same reason --  I think Sibelius is basically becoming yet another Avid chestnut:  expensive for starters and not updated significantly without gouging your wallet.  (I refused to pay for the upgrade to version 6!)  They don't release enough "point" updates;  you're lucky if you get a "x.1" that fixes some problems and then leaves the rest for the paid upgrade!

I tried the Notion 3 demo about 3-4 months ago, and I was really not impressed at the time.  The product still feels very "half-baked."  I somewhat like the look and the "tools" layout, but it just doesn't respond fast enough for me with either manual OR MIDI note-input.

(Note:  this is Sibelius' fatal flaw for me.)

Hey, what the heck happened to their demo?  I just checked and it says, "Available Soon" -- ???!??!??  Maybe (hopefully) they're doing some refining...

DEFINITELY don't consider it until you can try the demo.  I tried it for about a month, I think (it had a 30-day period, if I remember correctly), and I just kept becoming frustrated with the sloppy note-inputting (when you have to "fix" half or more of what you input...).
