I used Quickscore many years ago to create lead sheets for a church band. I just ran across this announcement and I'm going to DL the demo. It may not be Sibelius but it looks like it has real CC editing and piano roll. Might be interesting.

This appears to be a morphing of an old program from Voyetra, one of the first music software companies I had heard of, around the time I started using Cakewalk. Does look kind of interesting re: notation. So many other options now, I have Finale and Sibelius, but don't use either of them that much--Finale would be great, but so much of a learning curve, it seems. At least for me, and I have a classical music background (waaaaay long time ago) :)

I'll check it out. I love the fact that it loads vsts and allows you to edit the piano roll and midi cc. $180 is too much, but I saw on their site that they have crossgrades for $100. If it works properly it's worth $100. I've been using notion which is great, but they really need to add midi cc editing to it.
