Just out of interest... How many people can read and play the music shown in piano roll view? Seen a few videos on youtube with some people making 'tutorials' for different songs using a prv or piano roll.. I can't adjust to it.. But thats just me I suppose..
I read music very fluently, it's how I was trained, alongside a lot of ear training and performing from a young age. I still prefer the PRV for entering music (or playing a keyboard although I suck), I find it substantially quicker than using notation. Far quicker to enter and edit.
Everyone here is likely going to base their opinions on their own experiences and needs, understandably. From a personal perspective, the issue is that a well-rounded, or as you might say "working" musician, ultimately has to know their instrument inside out. As a guitarist, for example, you will not likely find a complete method based on tab or diagrams. Can you instantly name the notes of a F#m7b5 chord? How fast can you find B note on every string? Can you play thru a specific set of seemingly unrelated chords? Can you properly interpret a baroque piece? Improvise over Georgia? It takes knowledge to be able to do these things whether the knowledge is taught/passed along thru reading or other methods (it can be done!).
So how does one gain that knowledge? Generally speaking the only way to truly understand your instrument is to follow a complete path that encompasses scales, chords/arps, ear training etc. and without reading how is all this information communicated between people because ultimately, like cliff says, music is a language. As I said, it can be done, but usually only thru self-determination and some external guidance.
Don't get me wrong, one doesn't necessarily need all these skills to be a great performer or good musician in certain genres. I'm not sure Stevie Ray Vaughn could read a note. But for every famous musician out there, there are a thousand working musicians like myself who have to morph between numerous roles to survive. If I had not developed my skills thru reading it's questionable if I would have been able to get by as I have.
These skills also give you far greater control over your own music. You can tell other musicians what want from them and follow specific instructions just as easily if you speak and understand the language.
To put some numbers into perspective: I studied at GIT for one year after university, I was big into the Satriani, Vai, Malmsteen stuff at the time but had been convinced by my (excellent) guitar teacher at the time to become a more complete musician and was seriously studying jazz. His thinking was that, while I waited to get famous, I could make a living as a "musician" instead of pumping gas or studying law or something else which pretty much takes you out of the game. When I got to GIT there were about 700 guitarists studying there at the same time, only 3 players were given "Vocational Honors" which signified the school had enough faith in you to sign a document saying they felt you were capable or adapting to pretty much any musical situation.
Find me a player who doesn't read and I'll show you someone who likely can't quickly adapt to many paying musical situations and doesn't really "see" music as a whole. There may be exceptions, but few.
The irony (?) here is I'm pro-notation but never use it in Sonar, so I could care less at the moment. I use external notation programs. It would take more than a small makeover for Sonar to suit my notation needs so it;s just not in my radar.
