What I think would be great is just a better version of what is available now, with a floating toolbar that displays note markings (seriously - the drop down menu for selecting note values is wayyyyyyyy too slow), a way to write in tuplets, and a few things like that. That would be a
huge, huge help for those of us that use Sonar X for soundtrack work - we need to be inputting into a sequencer.
It has been very frustrating using Sonar all these years so far and not see any improvements at all. Surely it's not a huge task to do a few improvements like that. A complete overhaul would be overkill IMO. There's no need to make Sonar a publishing program too. It just needs a little attention to have a functioning MIDI staff tool.
I really hope we can see something like that in the near future. I do like the layout of the staff tools and it's part of the initial reason I got so hooked on Cakewalk. You can run the staff all the way across the screen, it's a bold big font, it's actually great to work with. With a toolbar, fixes and support for writing tuplets out properly etc, it would be fantastic and I would be stoked, as I'm sure many others would be too.
Please please please!!!
