Finale over Sibelius
I've owned Sibelius 1, and then v.2. I did not upgrade through the years (now Sibelius v.5) for one major reason.
While I liked Sibelius for some reasons, my personal need in editing music is not possible in Sibelius. That is, that when you edit music in Sibelius, such as entering a new note into an existing measure, all the other notes do NOT get pushed to the right into other measures, the way a Word Processor would behave.
Instead, all the notes in the existing measure get their time durations changed to make the whole measure add up to 1 whole value. I hate this!
So, I just got off the phone with Sibelius to see if they have added this "word processor" type ability with the new version 5 and was told "no, everything works on the timeline."
They will not get my upgrade business.
I then went over to Finale site to verify what I had heard years ago, and sure enough, in Finale, you have the option of moving all the notes to the right, further to the right and into new measures, when inserting a note. I will move over to Finale the next time I make a notation software purchase.
Why is this such an enormous issue?
Because as a synthesist, programmer, composer... using MIDI (which of us does not?), when you compose and play your music into a MIDI file and then bring that MIDI music into a notation package, you will want to edit it unto perfection. If the notes are not played perfectly, meaning the notes are a little early and late, then the notes can and will be in the wrong measure. So you'll want to clean it up.
This is why pushing notes to the side without changing their timing values is so critical.
In Sibelius, it will just arbitrarily change the values of your other notes to make it "fit". And then you don't have the same song you had initially. Impossible to work with in this manner.
I'm not too thrilled though with how complicated Finale appears. I was looking at all the menu commands and it seems overwhelming. Nevertheless, it has the feature I so desperately need.
