hi all linux audio devs
Advanced Gtk+ Sequencer libraries go to version 0.7.3.
http://gsequencer.org/download.html
Although the API is still unstable you might get insights, yet.
http://gsequencer.org/api/ags/index.html
* rudimentary JACK support
* refactored AgsTurtle to interface with RDF triples
* some API enhancements
Bests,

Hi all,
I have a RME madi fx card, but i found out that the minimal buffersize for those cards is 8192 samples, which is way to big for my use.
So i am thinking of returning the card, and getting the ‘normal’ rme madi (without the fx). As that seems to have a more sensible minimal buffersize of 128 (or so i am informed).
I wonder if anyone here that owns a RME madi ( or has access to) ever did a real world round trip latency test on it?
Of course it depends on the converters as well, but it would be great to have some numbers anyway.
cheers,
Fokke
Hello Linux Audio Community!
This is the announcement you have been waiting for.
We've come to the conclusion that doing a full LAC at the announced date is
impossible, as our sponsoring setup didn't work out, therefore we have decided
to go ahead with a miniLAC instead.
Since we have already planned a lot of stuff, we thought it would be a shame to
let all the work go to waste, so we asked a few people whether they'd be
interested in a more compact and reduced conference program.
What we can currently offer with the resources available are:
* a lecture track
* workshop tracks (one of which will use the c-base soundlab)
* live audio sessions
* hacking sessions
* tours around interesting berlin places
* linux audio nights
This miniature version of a Linux Audio Conference is still planned to take
place during the (kind of) announced date: 8.-10. April 2016. The location is
now set:
c-base, the spacestation below Berlin Mitte (http://c-base.org)
Our plan is to start off on Friday with a meet-and-greet evening at c-base,
where we will have an open stage for anyone who wants to connect their devices.
Since we don't have the originally intended resources, we will have to limit
attendance to around 150 participants.
Additionally, if there is interest for this (especially for people arriving
earlier), we'll try to organize optional visits to other Berlin locations on
Friday 8. April.
Please create an account on our wiki, to be able to set things up with us:
http://frab.linuxaudio.org (will later move on to
http://minilac.linuxaudio.org).
The wiki is still a work in progress, but should feature all necessary
information by the end of the week.
To satisfy your academic paper skills, we intend to support another crew that
could organize a second conference part at the FrosCon 2016
(http://www.froscon.de/), which is happening in Bonn 20th and 21st of August.
Here is a link to our issue concerning this topic on Github:
https://github.com/linux-audio-berlin/LAC16/issues/30
We hope to see you at the miniLAC16!
Cheers,
miniLAC16 Orga team

Well i might have to go that way if i can’t work this out. But i would prefer to use alsa directly if possible. The reason for me not to use jack, is not that there is anything wrong with it, on the contrary. The reason is just that it doesn’t make sense in my case, i don’t need any inter-app routing for this project, and it would just be another dependency. Adding jack to the mix doesn’t seem like the right solution to the actual problem...

Harry, you beat me to it. :)
My proposal is a workshop with a practical introduction to Faust plugin
programming. Please check
http://minilac.linuxaudio.org/index.php/Workshop#Workshop_:_Plugin_Programm…
for my blurb.
David, thanks so much again for pulling this off. I'm sure that this will
be a great event and I'm really looking forward to it! :)

Ahoy there!
Qtractor 0.7.4 (the tackiest gluon) has been released!
Y'all know the drill...
Qtractor [1] is an audio/MIDI multi-track sequencer application
written in C++ with the Qt framework [2]. Target platform is Linux,
where the Jack Audio Connection Kit (JACK [3]) for audio and the
Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main
infrastructures to evolve as a fairly-featured Linux desktop audio
workstation GUI, specially dedicated to the personal home-studio.
Change-log (since last release):
- Eye-candy warning: muted/non-soloed tracks are now shaded over the
main thumb-view.
- Faster and crispier VST plugin editor (GUI) idle cycles.
- Fixed all core processing when any plugin has more audio outputs than
channels on a track/bus where it's inserted.
- Added one decimal digit to all percentage input spin-boxes on the MIDI
Tools dialog.
- Added brand new and global option to disable the so called "catch-up"
default behavior (cf. View/Controllers.../Sync).
- Fixed some track control issues related to MIDI Controllers generic
mapping (cf. View/Controllers...).
- Try making Help/Shortcuts... dialog window modeless, as far as under
MIDI Controller, Inputs/Outputs Connections window also gets accessible
enough.
- Fixed some vertical scrolling and play-head line re-drawing glitches
introduced by the recent unlimited slack to editing beyond current
contents length on main tracks view.
- Added one decimal digit to the Pitch-shift spin-box on audio
Clip/Edit... properties dialog window.
- Added application keywords to freedesktop.org's AppData.
- Fixed local keyboard shortcuts on the Files organizer widget actions
and context-menu.
- Improved Mixer multi-row layout (patch by Holger Marzen aka. bluebell,
thanks).
- Fixed the Ctrl+drag/cloning left of a clip when towards near the
beginning of session.

All,
As some of you may be already aware, this past December I was notified
our current virtual server that hosts a broad array of outreach
services, including these mailing lists, will be decommissioned at the
end of this month. Since, I've been working on securing the
infrastructure and ongoing support onto a brand new physical blade. I am
pleased to report we are at the very end of what has proven to be a
fairly intense journey (needless to mention I learned a lot more than I
ever wanted to about sysadmin). Our new setup is considerably more
powerful and I am confident it will offer a significant improvement in
performance over the old one. As we enter the final stage in the porting
process, there will be a brief downtime tentatively scheduled for 11am
Eastern Time (East US Coast) tomorrow, Wednesday, January 27th. During
this time, you will experience inability to access hosted services,
including web and mailing lists. My intent is to have the transition
complete as quickly as we can do the final rsync and IP address
reconfiguration. I will let you know as soon as we've completed this
final step. Thank you for your support and understanding.
Best,

Is anyone here using ccmake version 3.4.1?
I've had a couple of people saying it segfaults when going through its setup.
I'm using V 3.0.2 and not seeing any problems at all.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
Hello there and again,
This time getting ready for the NYE. Prepare to party, the countdown has
begun... but first, let there be just one cheesier announcement ;o)
Qtractor 0.7.3 (a tackier gluon) is released!
Everyone is strongly invited to upgrade. No excuses.
Qtractor [1] is an audio/MIDI multi-track sequencer application
written in C++ with the Qt framework [2]. Target platform is Linux,
where the Jack Audio Connection Kit (JACK [3]) for audio and the
Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main
infrastructures to evolve as a fairly-featured Linux desktop audio
workstation GUI, specially dedicated to the personal home-studio.
Change-log (since last cheesy release):
- Slight increase on the number of decimal digits for the plugin
parameters while on the generic plugin properties dialog. Also applied
to automation curve node value editing.
- Unlimited slack is now in effect on editing over and beyond the
current session or clip contents length, on both the main tracks and
MIDI clip editor (piano-roll) views.
- Ctrl+click and dragging the left or right edges of a clip will now
make it spill over and replicate as many clip clones as it fits in the
left or right horizontal extent.
- Added View/Note Type and Value Type command menus to the MIDI clip
editor (aka. piano-roll) which opens the possibility for discrete
shortcuts to switching views eg. Note Velocity and Controller views
(after a kind request by yubatake, thanks).
- Fixed the conversion and/or override of MIDI clip offsets when moving
and copy/pasting across tempo/time-signature changes.
- Fixed MIDI file track/channel duration estimator, which was giving
quite wrong and way too short reads.
- Fixed a drag-and-drop bug over the main tracks view, when new tracks
were being inserted at the top and not to the bottom as is normally
indicated by the floating visual placeholder.
- Fixed LV2UI_Resize handle from extension_data(LV2_UI__resize), now
passing LV2UI_Handle in first argument to ui_resize(), as found correct
and needed for resizable/scaleable LV2 UI's, most specially to ssj71's
so called Infamous Plugins, thanks.
