Hey guys,
I'm interested in buying or building a 4X4 trigger pad. M-Audio's Trigger
Finger looks nice, but I just want the pads. I have experience building
circuits, but I'm not an electrical engineer (but I am aerospace tho..).
Any DIY projects would have to keep that in mind. Any suggestions?
Libc6 is upgraded on Debian Sid and other distro updates. This set of objects
is the very heart of our linux. If it ails, well heart failure can be fatal.
The new libc6 is fine. It requires newer 2.6 kernels but I assume we are all
onto these kernels already so no problem here. Or is there?
A while back, jackd audio users were recommended to place a
LD_ASSUME_KERNEL=2.4.19 in their /etc/profile or environment setup. (I have
seen this recommended for other packages as well) The bad news is that this
is a heart-attack. If it be in the profile, it breaks bash and any
application run through bash. Other stuff make work OK but one might not be
able to log on if bash or sh (symlinks to bash) be the user shell. (Boot up
that knoppix CD, mount rw and usermod -s csh username) If this is set deeper
down, well, time for panic.
I do not know if the LD_ASSUME_KERNEL is still relevant to jack. However, do
get rid of it before upgrading.
pyliblo is a Python wrapper for the liblo OSC library. It does not yet
wrap all of liblo's functionality, but includes everything you need to
send and receive almost any kind of OSC message, using a nice and simple
Python API. OSC can hardly get any easier :)
Also included are two scripts, send_osc and dump_osc, which are similar to
the well known sendOSC/dumpOSC programs, but much simpler and less
cumbersome to install.
Get pyliblo 0.5 here:

Announcing the 20070418 release of WhySynth, a DSSI softsynth
plugin.
New since the last major release:
* Two new oscillator modes: phase distortion similar to that used
in the Casio CZ series synths, and another FM mode.
* GUI enhancements.
* Improvements to the envelope generators, making them more
responsive to realtime parameters changes.
* A few new patches.
* Some GCC 4 fixes.
Find WhySynth here:
http://home.jps.net/~musound/whysynth.html
More information on the DSSI plugin standard, available hosts
and plugins can be found here:

Geoff,
Thanks for the information. I have recieved my Delta 1010 and it
was very easy to setup in qjackctl. I just chose "hw:1 M Audio Delta
1010" for Input Device and Output Device. It also works if I choose
"hw:1,0 ICE1712 multi". Could you or someone else tell me what the
difference is?
In the Qjackctl settings box, I clicked the Realtime box and set
the priority to 79. When I restart qjackctl, it shuts down with error
messages:
In realtime mode (-R) the client timeout must be smaller than the
watchdog timeout (5000ms).
Could someone tell me what this means and if I can adjust or fix the
settings? For now, I just unclicked the Realtime box in Settings.
By changing the the Periods/Buffer to 3, and the Frames/Period to
512, I have a latency of 32 msec, and I am getting very few xruns. I am
now recording digital tracks for the first time! Thank you! I hope to
improve this latency after getting Ubuntu Studio all set up and working.
My /proc/interrupts folder now shows the Delta 1010 card:
$ cat /proc/interrupts

I assume the ICE1712 is the Delta 1010's chip. Is there a way to remap
or change its interrupt priority?
Thanks,
Dave

is getting better tho, so with just one card you may find it will work
fine.... and get that nvidia driver back in there when you get your 1010.

Greetings:
While researching VST-related materials I came across this page :
http://www.syntheway.net/
Besides the inherent interest of the software listed on that site,
there's the interesting point that the author has indicated
FST-compatibility for his work, complete with recommended system
requirements. The plugins are inexpensive (between US $30 - $40),
binary-only, and no source is available. However, the little testing I
did last night showed me that the plugins are very cool, with some great
sounds. My tests, btw, were run on openSUSE 10.2 (JAD), with FST 1.8 (my
build). Other than the annoying "reminder" the plugins sounded great. I
tested the organ and choir instruments and the room emulator, I'd
recommend them to anyone looking for more Linux-happy VST plugs.
Anyone else here have any experience with the Syntheway plugins ?
Best,
dp
Folks,
Is there anything else out there than QSynth for managing fluidsynth
synths ?
I run into too many bail outs from QSynth to be confortable and
trusting with it. Sometimes it'd just bail out when doing 'setup' on
the fifth instance of a synth, to load a soundfont.
I might be tempted to write one. As far as I see it now, the
documentation for both fluidsynth and qsynth consist mostly of the
source code itself. Without even knowing how it works, I'd like to be
able to set at least the volume of each instrument inside a loaded
soundfont. qsynth has only a global volume for each instance of a sf.
But then, maybe that's calling for something like re-writing the sf
player altogether. It'd be also fun to have separate audio outputs for
each instrument coming out of a soundfont.
In the meanwhile, is there any alternative soundfont player/manager
out there that's worthy of being stable and trustable ?
Cheers.
Hello list,
Last night I decided to compose a little groove using Hydrogen and
Rosegarden. I setup Rosegarden to use Jack sync, and was able to
press play in RG and have Hydrogen start playing. All is good,
except...
RG puts a 2 bar count-in when you hit record. Hydrogen wants to start
playing on bar -2 instead of bar 1. How do I get Hydrogen to wait
until the two-bar count-in is complete before playing? I've googled
like crazy and read all of the RG docs, but can't seem to find any
reference to this problem.
Thanks,

I built a computer to run Linux and Ardour. I installed a GeForce
7300 GS video card in it. With help from Paul Davis and others on the
LAD forum, I was able to get jack/ardour/hydrogen/etc working. However,
xruns problems make these programs unusable. I think the video card is
causing the xruns, because they go away after about 15 seconds of no
motion with the mouse or files in the GUI. As soon as I move the mouse
or open a popup menu or anything else, the xruns return and sequire
several seconds to go away.
With this card I am also getting long streams when I move things
around on the Windows desktop. The ghosting also happens in Ubuntu, but
is not as severe.
I have read a little about changing interrupt priority at
http://lowlatency.linuxaudio.org/ , but I could use some guidance and
opinions on what to do.
I plan on installing Ubuntu Studio when it comes out in a couple of
days.
I have a Gigabyte GA-965P-DS3 mobo and a Pentium D-930 processor.
Thanks,
Dave
