And I was looking forward to something to do in my retirement!
Unfortunately, that's 10 years away. :-(

hi everyone,
in my never-ending search for midi sequencers, I ran across Attrk, a
rewrite of the tracker ttrk:
http://www.lumanmagnum.net/physics/attrk/index.html
I have been able to build it just fine, but I keep running into an
issue with rtc access. the application wants to be run as root to get
realtime access to the realtime clock (rtc?). I've never run into
this issue before with midi sequencers, so I've been doing some
reading. apparently this was an older way of getting accurate timing
from a midi sequencer, but isn't used much anymore (my assumption
might be incorrect, please correct me if I'm wrong). so what is the
*proper* way to handle this sort of thing on a modern system?
thanks,
Josh
hi, sorry for spamming the list today :)
are there any tools for searching/downloading from freesound.org from
the command line? I've been searching google, but to no avail. if
there were a simple way to script such a tool in, say, bash or perl (I
am not a programmer, so python might be out of my league), any tips on
how to do this would be very much appreciated.
thanks!
Josh
Hi
Nano-Basket v0.1 has been released. Source files are available from
http://github.com/royvegard/Nano-Basket
Nano-Basket is a configuration software for the Korg nanoSERIES
MIDI controllers. It's intended to run on operating systems where
the official configuration editor is not available (i.e. Linux).
It's written in Python, using pygtk for the GUI.
This is the first release. The feature set is limited to storing
scenes to the nanoKONTROL device.
Simple usage instructions are available from the wiki page:

On behalf of the guitarix team I'm proud to announce
Guitarix Version 0.11
Guitarix is a simple Linux Rock Guitar amplifier and is designed
to achieve nice thrash/metal/rock/blues guitar sounds.
Guitarix uses the Jack Audio Connection Kit as its audio backend
and brings to the jack audio graph a mono amplifier input/output port,
and a FX mono input with two (stereo) output ports.
Guitarix provides a jack midi input port to connect a midi controller
(midi learn) and a (3 channel) jack midi output port, feed by a
(scalable) mix of the tuner and a beat-detector.
Release 0.11.0 comes with following changes :
Users visible changes:
- new version of the impulse response parameter editor. You can
now graphically define a gain line to be applied to the IR data,
e.g. emphasize a part of the early reflections or damping the
reverb tail to make it fit to your guitar sound.
- the multi-line distortion effect now has 4 frequency bands and
is better optimized
- fix regression from version 0.10.0: now the default preset file is
created again if it doesn't exist (e.g. in new installations).
Changes that might be interesting for Developers:
We put the Guitarix widgets into a library, with the goal of
making them usable independently from Guitarix. You can build
it as shared library and there's a c++ (gtkmm) wrapper, a python
wrapper and glade support. Check it out and look for examples
in those directories, or just build a nice looking display with the
glade editor, and of course ask in our Guitarix forum (it's still
alpha).
As a side note, Guitarix is now in debian (unstable), of course at
the moment still the previous version 0.10.
have fun

For capture, guitarix uses the great 'jack_capture'

For extra Impulse Responses, guitarix uses the
zita-convolver library, and,
for up/down sampling we use zita-resampler,
both written by Fons Adriaensen.

Hi,
I'm trying to setup a system where alsa app is outputting its channels
to jack. Problem is that it seems that the example code always auto
connects the outputs to physical ports through jack, which is not what I
would want, especially as the app has more outputs than my soundcard
does. I would only want the output ports to appear to jack and then I
could patch them with patch bay. Is there some way to accomplish this.
Another question, which handles the same problem. Is there any way to
have similar kind of functionability as patch bay does, but to the
reverse direction. So if someone connects ports a and b, they would be
automatically disconnected. Which would solve my first problem and
problem with all auto connecting apps.
Thanks,
.j
Hi,
I'm running Rosegarden 10.02 on Ubuntu Lucid and am having problems with
audio output. I am not using external midi hardware so am reliant on
software synths.
The steps I've taken are:
Run qjackctl, run Qsynth (which has been loaded with Unison soundfonts).
In Rosegarden I've selected General Midi Device from the Playback
parameters and 1. Acoustic Grand Piano from the Instrument parameters.
When I load a midi file (created by Lilypond) it plays with no audio
although the level meters on the track do indicate it's getting some
kind of signal.
What am I missing? And, does Qsynth need to be running at all?
Many thanks,
Peter

Hi all,
I'm trying to build galan-0.3.0_beta9 (http://repo.or.cz/w/galan.git
/snapshot/6c642c305bb62689ff8ffd8b7e03c940c8f351e1.tar.gz) on Kubuntu10.04
but I'm stuck with the linking step.
Compilation goes well:
./autocvs
./configure
make
Everything seems to have been compiled (especially libogg_ra.o, libvoice.o
and libjackplugin.o and the corresponding .la and .lo files) but 'sudo
make install' installs in /usr/local/lib/galan/plugins only what is
defined in the Makefile as plugin_LTLIBRARIES, as well as the main
libraries in /usr/local/lib/galan but none of what is defined as
EXTRA_LIBRARIES (such as libogg_ra, libvoice and libjackplugin) and dies
with
libtool: install: error: cannot install `libogg_ra.la' to a directory not
ending in
in what ? Well, libogg_ra.la for example says libdir='' so I probably have
to supply a directory name somewhere but I really don't know how.
Can you help me deal with those extra (but fundamental) libraries ?
Thanks to Julien and Rui Capela. Being a musician and engineer, this seems
to be a great place to land in and learn new stuff in this world
of Linux audio. Currently, I am still not able to find document that I need
to solve 2 existing problems:
*Question on using JDelay:*
I have only one web source that has some details about using this tool:
http://www.kokkinizita.net/linuxaudio/ and this reads: "It uses a phase
measurements on a set of tones to measure the delay from the output to the
input".
How do I use these phase measurements and how do I pass in these tones? Are
they special tones? What kind of oscillator do I need to use to generate
these special tones? How do I pass in an audio tick or click? How do I do
other settings?
$ jack_delay -h --help does not show me the help menu
*Question on using QJACKctl:*
I was able to create some basic setting, load and read latency that gets
printed on the terminal. But what do the parameters on the setting tab of
console pop up mean? No soft mode, monitor, priority, time out etc and the
options tab. How do I use these options and tine tune them in order to set
the minimum feasible latency for the application that I intend to develop?
Above all, if the drop down menu options does not allow me to choose lower
sampling rates, what command do I use on the CLI to do the setting. Or Do I
need to edit QJACKctl's .conf file to set lower sampling rates manually.
My Intel sound card supports sampling rates of 8kHz and 16 kHz. I confirmed
this by looking into Audacity device ID setting. I know that I am asking
some basic stuff but my problem is that I do not find the right
documentation for solving my problems.
Your reply in this regard will be greatly appreciated.
Kind regards,
-F
