Re: The Orchestral Staff Attribute Bug
G'day bidderxyzzy,
First, I never would consider a singer more computer savvy than I am "competition". On the other hand, he is the last person to whom I would want to explain why I used an ugly kludge to get a desired result.
Ya never know - s/he might understand completely - or even have some better ideas!

I don't pretend to be anything but an advocate for my subspecialty.
Allsame the rest of us - but I do try to be open minded about others peoples needs and not simply focussed on my own. This is not criticism BTW, just an observation.
As far as "backward compatibility" goes, I think it very unlikely that fixing this problem would change the result of a successful kludge, except to make it unnecessary. I leave it to the usual gadflies to provide a counterexample.
I dunno... Maybe it would, maybe not - it will depend entirely on the current code and how the putative change is impemented. I imagine you are correct, but I don't know.
Ya know, I've never been called a gadfly before - do ya think i could get much altitude? How hard would I have to flap my itty bitty wings? I'm pretty heavy ya know, but I've always dreamt of being able to fly!
