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 !
In an effort to eventually bridge the gap between users and developers, and
specifically explore the contributions users that aren't programmers can
make to free and open source software, I have designed a short survey for
More information and the survey itself is available on
I'd greatly appreciate any participation from developers. As mentioned on
the page, I will compile the results of this survey into an infographic. I
will also eventually publish all of the results freely to anyone, so
everyone can have a look at the data.
I hope this survey can give some good data, that can spark some good
discussion on how we can further integrate users and developers, and make
more use of the great community we have!
Cheers and merry christmas everyone,

I'm currently trying to make an arduino controller that'd allow me to
control easily effects and such with only a few rotary encoders, without
the tedious mapping.
So, basically, I need to get the parameters FROM the programs (when
selected or sweeping though them thanks to a button) and either change
the CC/OSC accordingly on the midi/osc controller or use mididings (or
equivalent) to map things properly.
Simply put, is there a way to get a list of hosts, a list of effects
within host, a list of parameters within effect, and the value of a
given parameter ? Oh. And the names or any kind of ID would be nice.
(Male and Falktx, I think you can help me with this...)
Thanks a lot for you help !
Hello LAD, I'm working in company which is developing a guitar pedal board
which runs Linux (arch) and my task now is to make the kernel's usb audio
driver more appropriate to our sound card. I'm kinda lost in this since i
have a brief knowledge on usb protocol so I was hoping that you could give
me some directions on how can I optimize the driver latency wise, any tips?
