Re: [Bluemusic-users] feature request?

[Steven Y. <ste...@gm...>]

Hi Hector,

Sorry I got confused, should I go ahead an implement your original
request?  If so, I am wondering if it is better to present something
like "Priority: " with a number box and just use chrt to make it
easier for all linux (and osx?) users to do, or maybe it'd just be
more flexible if I did it as a generic "run this command after
starting csound"?
