Re: [LAU] Slightly OT: Live gig with Linux AV

The recording of my first linux performance with my band Bonjour, Ganesh!
from last Saturday (3-20) just got loaded up on archive.org:

I'm driving a laptop running a stripped-down Ubuntu 9.10 install with an
M-Audio Axiom 61, playing a couple public domain soundfonts using
fluidsynth, and bristol -hammond, all through JACK and ALSA. A complete
write-up of the rig is here:
http://lukepeterson.com/2010/02/07/arriving-midi-keyboard-live-rig/

I switch patches by changing the midi output channel on my controller: I've
got various soundfonts attached to midi channels 1-8 and bristol running on
channel 9 (and 10 and 11).

I've experienced a few issues, and I'd appreciate any advice you all can
offer with the following items:

1. fluidsynth (via qsynth) sometimes will unreplicably decide to start
playing the patch I've got attached to channel 1 on channel 9, which means I
sometimes end up getting a fair amount of Rhodes in my Hammond. It's a quick
15-second fix and it really doesn't sound all that bad, but it makes me
nervous. Anybody else experienced this?

2. If I set bristol to listen to channel 1, it always plays regardless what
channel I set my controller to. In the hammond implementation, channel 1 is
mapped to the upper manual, channel 2 to the lower, channel 3 to the pedals.
Channel 4, despite being outside of bristol's assigned range, still gives me
hammond. I solve this problem by assigning bristol to the highest midi
channels I'll use (since this only happens with higher channels, not lower
channels), but it would be nice to have some flexibility.

3. I've read all the documentation and forum posts, and looked through the
source code, but I can't for the life of me get bristol to run the mini and
hammond sim synths simultaneously.

4. I need to find some way to level my patches: some of my soundfonts are
much louder than others, and while my expression pedal is mapped to volume
in both QSynth and bristol, transition between patches can be a bit rocky.
It would be great to normalize the volume obtained from each of the patches
(but still pressure-responsive), and map my expression pedal or a slider to
a global volume control. I'm sure there's an easy fix, but I haven't done
enough digging to find a solution.

Aside from these issues, at this particular show I had almost nothing out of
my monitor (a consequence of playing in a 10-piece band at a club with 3
house monitors on stage and being too lazy to bring my own), and was a
little disappointed in what I felt was a bit of a distant performance. But
altogether I'm proud of having figured this stuff out well enough to
perform, the quality of the music and performance notwithstanding. I took a
lot of advice from the archives of this list, and from forum participation
and documentation authored by members of this list, so thank you very much
for all your help! (and, if any of my bandmates happen to read this, I also
very much appreciate their patience while I spent a bunch of rehearsals
messing around with shell scripts)

The most prominent keys are in Ready to Wait (

and The Dog Song (

Thanks again,
