come to #ubuntustudio-devel sometime, or #opensourcemusicians... i didnt say
i was using a -generic kernel, but lots of folks are these days and getting
nice results. i find most users dont need low latency anyways, really just
for realtime effects and sotfware synths... i usually use several different
jack profiles anyways ranging from 1.2ms to 60+ms depending on what i need
and how hard i need to work the system... this is the wnclug over here in
asheville http://wnclug.ourproject.org/ ...i had a presentation get snowed
out, but 3 or so folks were there and i really just talked about JACK a
bit... i was thinking about doing more of an edutainment kind of thing...
bring the bass in and do some looping with sooperlooper, triggering it with
a midi keyboard... then i have the midi keyboard to demo yoshimi or
xsynth/whysynth or whatever, and maybe show an ardour session and talk about
the workflow a bit (inserts, sends and plugins or whatever) and show
JAMin... im hoping to have about 15 or 20 minutes of stuff planned, and take
questions and keep it to 45 minutes or so... maybe we can pool our resources
sometime and do something more officially relating to ubuntustudio and the
ubuntu-nc team... im over in charlotte often enough to make something happen
over that way...
