This program is very much in progress. If you like it and
are using it I recommend that you fetch a new version every
few weeks from pub/music at Princeton.edu. Note that it
is not *really* a real-time mixer in that you can't change
the attributes of a sound while it is playing (yet). This
will come sooner or later. Please let me know if you have
any suggestions, comments or even if you just want to
kibbitz. I like this program a lot and have been using
it very heavily in my own work.
The program included in the app.wrapper called
enableFixedPolicy trips a flag in the kernel
which allows the mixing in this application to
run at a higher priority. This program should
be chowned to root and have its setuid bit set
chown root enableFixedPolicy
chmod 4755 enableFixedPolicy
you have to do this as root, of course.
if you don't have this program there is nothing
fatal, it simply makes the sound driver work a bit
better on long mixes, and keeps its priority from
being degraded. BUT it can make it difficult for
other processes to get attention, so it is not too
polite to run it on a shared and networked machine.
(RT is probably not going to work all that well under
these conditions anyway.) If you don't want to use it
just rename it or something and there will be a mild
complaint in your console log when you start up the
application, but you won't notice anything different.
