QMidiArp 0.5.2 has just seen the light of the day. It brings mainly
two improvements. One is a comeback, that of tempo changes on the fly,
and that now includes also tempo changes of a potential Jack Transport
master. Also the Jack Transport starting position is finally taken into
account, so that QMidiArp should be in sync also when starting the
transport master not at zero.
The second one is Non Session Manager support, mainly thanks to the work done by Roy Vegard Ovesen!
Note that for compiling in NSM support you will now need liblo as dependency.
Enjoy, and enjoy LAC in Graz this year
QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO.
Everything is on
o Tempo changes are again possible while running, both manually or by
a Jack Transport Master
o Jack Transport position is now taken into account when starting,
QMidiArp used to start always at zero
o Muting and sequencer parameter changes can be deferred to pattern
end using a new toolbutton
o Modules in the Global Storage window have mute/defer buttons
o Global Storage location switches can be set to affect only the pattern
o Non Session Manager support with "switch" capability (thanks to
Roy Vegard Ovesen)
o NSM support requires liblo development headers (liblo-dev package)
I'm happy to announce OpenAV productions: http://openavproductions.com
OpenAV productions is a label under which I intend to release my
linux-audio software projects. The focus of the software is on the workflow
of creating live-electronic music and video.
The release system for OpenAV productions is one based on donations and
time, details are available on http://openavproductions.com/support
Sorcer is a wavetable synth, and is ready for release. Check out the
interface and demo reel on http://openavproductions.com/sorcer
Greetings from the LAC, -Harry
lately I had to fight big XRUN troubles, and thanks to this forum I
finally solved that. This excellent thread saved me:
On my long quest, I tried to see a little bit more what happened with
the IRQs on my system. I searched for a kind of 'top' utility to monitor
the interrupts, but the only apps I found were either deprecated, or
missed some cool features.
So, I ended up writing my own tool to monitor the file /proc/interrupts.
It's available a this address:
As its name indicates, it behaves pretty much like top, but for interrupts.
It's quite a simple thing, that I tried to enhance a bit with some cool
+ refresh period can be specified.
+ two display modes: display interrupts for every CPU, or only a sum
of all CPU.
+ display every interrupt (sorted like /proc/interrupts), or only
active interrupts (sorted by activity).
+ in case the number of interrupts changes during the execution of
itop (due to a rmmod/modprobe), it's handled without any fuss.
+ command-line options are also available as hotkeys for convenience.
+ at last, the program display a summary on exit. The idea is that
this summary could be copied/pasted in emails to help debugging.
If anyone is interested, feel free to try and comment !
Hi there everyone, specially developers.
I think we should stop assuming releasing source code is enough.
[GNU/] Linux is getting more user friendly, and most users are not able
to compile software,
plus some distributions make it specially hard (debian, ubuntu, fedora,
opensuse) by having the libs installed but not the headers.
Releasing software on windows or mac, even open-source, *always* comes
in a binary,
and most users come from there.
Now, I have a "toolchain" repository for ubuntu 10.04 with gcc4.8,
python3+qt4 and a bunch of other useful stuff.
I use this to get generic linux binaries that (from what I know) work
I can make a developer-oriented tutorial on how to use that, so that
developers can provide linux binaries to its users.
Would that be something useful to Linux Audio?
WORLD is a free software speech synthesizer on the basis of a Vocoder.
It has been widely used as a backend for UTAU but it should be also
possible to use it as a backend for eSpeak and other accessibility
and/or music applications such as the "Singing Computer". My modified
version of WORLD uses the well known vorbis codec for compression. The
world4espeak synthesizer is interface compatible to MBROLA, and can be
used to synthesize both singing and speech in real time on a modern
computer. It is hosted at gitorious.org . Currently there are no
voices yet, a manual how to create voices will be published soon.
I have played around with petri-foo the first time, and I am thinking
about switching from specimen to it.
Is there a utility to convert specimen banks to petri-foo banks? As far
as I can tell, it is a simple XML transformation, and I would try that,
if such a utility does not exist.

Since this didn't make it yet to the LAD list, I thought I'd better forward it -
The Linux Audio Conference submissions deadline has been extended! It is
now February 3rd, 2014 (23:59 HAST)
So, if you were considering to submit a paper but couldn't make up your
mind yet, here is your chance to become active! Never forget that this
conference lives through the people participating in it.
February 3rd is the new deadline for all submission types: papers,
music, installations, workshop proposals.
Check out the link below for more info:
Please spread this information to anyone who might be interested.
If you have any questions, drop us a line at lac(a)linuxaudio.org
We are looking forward to seeing you in Karlsruhe in May!

If the community is willing to pay for it, sure.
But I find that a bit hard to believe...
There's a difference on how KXStudio repositories are done vs regular
Debian and Ubuntu usually build against a specific version, and don't
usually do backports.
on KX repos I'm starting build all packages the same way (ie, the
generic linux builds), and update software very often (sometimes minutes
after release :D ).
I hate when distros only package new stuff for the their newest,
unreleased/testing/upcoming version and completely ignore the users
running stable versions... :(
