Help Me Decide

I've got Sonar Professional  -  latest version - bought the software in Sept. 2015.
 
I midi assemble my arrangements using the Tyros 5 (Yamaha Keyboard arranger)   I examine my notation of my scores (via usb stick) using Sonar Pro.   I get by with it for editing double notes and changing notes in counter melodies.  I have no problem with Sonar Pro editing my notes and saving to midi file format 0.  My DEF file is configured nicely to use any of the Tyros 5 instruments.  I do not use any other 3rd party instruments or loops.  I create my 16 tracks live.  I see the lifetime upgrade to Platinum good til August 31st 2016.  If I knew the Notation or staff View of the software was going to developed more like what Sibelius offers, I'd get that Sonar Platinum lifetime upgrade for $299 in a flash.  This is what I'm pondering over.  BTW I am a registered owner of Sibelius 8.3.  Sibelius has no Soundset for the Tyros 5 which encouraged me to purchase Sonar Professional last year.  I need to hear my Tyros 5 instruments and make notation corrections hearing the results.  Can you offer any thoughts?

How about a more flexible screen resolution of the staff view..zoom in..zoom out..

The Tyros 5 Def with a workable Staff view is a nice facility for my work. At least I can hear the actual T5 instrument notation changes at any time with Sonar Pro open

I agree there is no way that Sonar staff view will ever compete with a package like Sibelius (or Finale). But I don't see why you can't use your Tyros instruments in Sibelius. You'll need to create a manual soundset I guess but there may even already be one that you can import. I haven't used this with Sibelius but it's a pretty standard feature to be able to define sound names and bank/program changes. A quick look online suggests it wouldn't be a problem. You should also be able to Rewire Sibelius into Sonar.

I don't really understand what you mean by that. You mean you don't want to create a manual soundset for Sibelius or that it's easier to use Sonar because it already has an instrument definition file?

I know exactly what you are talking about Alan.  Like you, I use my Yamaha MOX6 to write songs using at least 8 of the available 16 tracks in the MOX, then transfer the midi to Sonar for easier editing.  You have the Tyros Instrument Definitions already loaded into Sonar, so you can change instrument sounds from within Sonar and then, depending on which new instrument you choose, change parameters of that instrument (velocity, duration, note position etc) to suit your needs.  I do the exact same thing here, with the possible exception that my MOX is on the other side of the stage, so I use a Roland A-800 Pro midi keyboard to play the MOX.  As far as the staff view...no improvements should be expected ever, as Cakewalk has mentioned before that programs like Sibelius do the job sooooo much better. 
 
With that in mind...and I have not tried this, even though I have Sibelius 7 First...might it be possible to to open up Sibelius as a Rewire device and use both simultaneously that way?
