Hi all,
Thought I'd report on my first live gig experience with linux (or anything
else for that matter) at the placard headphone festival:
http://state51.org/placard/
For those that don't know, the festival consists of lots of performers doing
20 minute sets back to back - all listenable to on headphones only.
I was running jack and my apps as root using SHED_FIFO on my Thinkpad r31
running slackware 9.0 and the audioslack ll kernel and alsa packages:
http://www.audioslack.com/
I'd set up jack on a huge buffer (4096) as latency wasn't important for me, I
had no live input and just wanted 100% glitch free playback. Also enabled
softmode to stop the server ejecting apps if anything went too wrong.
Before the gig I went through my cron jobs commenting them all out just in
case. slocate is particually annoying - I guess most people disable this
anyway - even with jack using such a large buffer, all the disk access caused
problems.
I wanted to keep the setting up as quick and simple as possible, so I'd
written a shell script to launch jack with the right settings, launch my apps,
load samples and connect them all together with aconnect automatically.
The applications I was using are new software I have yet to release, a midi
sequencer/sample playback engine that uses a lot of generative and alife based
processes, and a very small polyphonic multitimbral synth based on the code
from SpiralSynthModular. I'm trying to get the synth into a releasable state
very soon.
There is audio here of the 20 minute set:

Excellent.
I did my first gig with linux at the end of April. I was using mostly
SC3, and a bit of Klupper through Freqtweak. SC3 was used for
manipulation of live instruments, triggering larger files and sequences.
I also used my UC16 to control all parameters in SC3. all that done on
my desktop running gentoo and jack of course. All the prepared sound
were done in linux too, using various bits and Ardour to put them
together. The live instruments were as follows: sax (alto double tenor),
violin, cello and symbals.unfortunatley i dont have a recording as of
yet. All i have is picture were you can just about make out my screen
with emacs running in the bottom right corner.
it's there:

me too! last tuesday night on kpfa.
http://www.kpfa.org/archives/music/archives.php?id=76
i'm going from 38:50 to 1:17:30 on this broadcast segment. it's
chaotic, running SC3 on a mac powerbook and SC3 +jackrack + freqtweak
on my planet-ccrma laptop simultaneously. i had live mics running
into the linux machine, played violin and electric bass, while
running their lines into the mac laptop. lots of ffts.
had a freqtweak crash about 3/4 of the way through that took jack
down with it! accessing presets (the freqtweak preset fader, trying
to load a preset) froze freqtweak and jackd, qjackctl. couldn't kill
jack from qjackctl, had to type. live typing!
the sudden ending is a specific fft magnitude freezer popping all SC3
output to -1s on the mac. a problem i thought i could avoid. oh well.

Can you reproduce the problem you had with freqtweak presets? Or can
you describe more exactly what you did when it crashed? That's not
something I like to hear :)

slocate is always among the first packages i remove after installing a
system. Have no use for it, and it is very annoying.

(S)locate is extremely handy. Let's you search your entire system in
notime. Maybe you should just disable the cronjob that is set up by the
installer.

I do find locate a very practical tool, and it's not necessary to
remove it just because of live gigs. For my first (and only) Linux
live gig at the LAConf2 I just set up a dedicated performance
runlevel, where cron is stopped. This runlevel could also be used to
stop other annoying applications. "telinit 3" (or whatever number was
chosen) then puts me into this runlevel.
My gig at that time went very smooth, except for having to fix an
annoying ground loop by unplugging the power chord (DI box didn't
help). I did only use Pd in OSS mode to a Terratec USB device, no jack
or whatever. For me just having one single point of failure in Pd was
an important thing. As nice as freqtweak and jack and all these things
are, combined they could be risky. With my gig, as long as Pd kept up
nothing really could break. And I had hammered Pd while rehearsing for
the concert so I knew it would probably not crash with the patch I
used. BTW: to a traditionally trained musician like me it still feels
strange to do "laptop rehearsals". ;)
Oh: Dave, wonderful concert, very cool music. You should apply for
releases on major netlabels like Monotonik. ;)

I had hardware issues too, although this was caused by a soldering
problem that took a few minutes to find. the setup for 100 headphones
and 4 performance spaces was pretty complex...

I'd rehersed with jack a lot to make sure it was up to it - indeed, I
don't think I could have got the solid results without it. Next time I
think I'll slot in some midi controlled effects, but it will all need a
lot of testing.
And I had hammered Pd while rehearsing for

pd was used by a few other performers - a few of us were practising live
programming (http://www.toplap.org) (me through simply coding lsystem
rules live) one of the pd performers managed to write an infinite loop
into his pd patch that produced a pleasing squeal for a few seconds :)

yeah, we need more tactile interfaces I think.
