hmmm still can't find the download, all I find is the documentation?
 

Sixfinger,
 
I bought Presonus Studio One Pro recently and there is a download link to Notion Demo in my account so maybe you have to create an account with them (easy to do and free) to get the demo link. I cannot see a download link  anywhere else.
 
I am going to try the demo myself. One of my requirements is the ability to scan printed or import PDF scores, convert to an editable score and also export to MIDI so I am hoping it can do this as well as SmartScore X2.

I really like Notion (still on 5). And their iPad app is great too so notation is all over the place now ;)
 
I used to like Finaly a lot but it got a bit... "old" for me.
 
EDIT: I see they have something called Progression which seem to be aimed at guitarists

+1 for Notion.  The only thing it won't do is a slide/bend from a ghost note, which I find irritating.  I reported it N4, still the same in N5.  I haven't upgraded to N6 yet, but prolly will at some point for S1/3 integration.  G-Pro is OK, but kind of niggly to me.  A new version has been announced for later this year.  GP6 is ancient at this point.
 
FYI, Notion has everything Progression has plus more.

Still the same in N6. I checked when you mentioned this previously. There may be a will, but I was unable to find a way.

Ok thanks, it's true once I had an account I could access the demo.
