Hello all,
I would like to introduce a new development tool, Static Function
Property Verification, or sfpv.
sfpv is a static analysis tool for C/C++ which is designed to find one
common class of real-time related bugs, calling unsafe functions from
a real-time context.
sfpv uses annotations to mark functions and the Clang/llvm API to find
relationships between functions (eg. the call graph).
It uses this information to perform basic deductions on known
information (ie explicitly marked functions) to find inconsistencies.
Ideally this tool could be run on a project with only the real-time
entry points marked (eg the jack process callback) and errors would be
emitted for any unsafe functions called.
For simple C codebases, this is mostly accomplished currently, though
not all common safe functions in libraries have been white-listed yet.
Basic C++ code also works, though template and class hierarchies are
not guaranteed to function as expected.
The source code and basic documentation can be found at
http://github.com/fundamental/sfpv
This effort is largely based off a unsuccessful Google Summer of Code
proposal, which can be found at
http://www.google-melange.com/gsoc/proposal/review/google/gsoc2012/fundamen…
Anyone interested in discussing this tool should be able to reach me
in #lad as fundamental.

jack_capture
============
jack_capture is a program for recording soundfiles with jack.
The default operation of the program is executed by writing
"jack_capture"
in the terminal without any extra command line options:
$ jack_capture
...which will record what you hear in your loudspeakers into a stereo
wav file.

Changelog 0.9.58 -> 0.9.62:
---------------------------
* CHANGE IN BEHAVIOR: The --daemon option now also suppresses all
console message.
* Support for using a config file.
A file in the distribution called 'config' can be copied into
~/.jack_capture/config and modifed as needed.
* Allow to remote-control jack-capture via OSC. (Robin Gareus)
(see --help-osc)
* Added exec-hooks: jack_capture can launch an external app in
fire&forget mode (from the disk-thread). (Robin Gareus)
* When it opens a new file for writing
* When it closes a file, recording finished
* On file-name-rotation
* When first audio frame is received.
* Write a timestamp file with sample-accurate system time of the start
of recording. (--timestamp) (Robin Gareus)
* Forced file-name rotatation every N audio-frames. (--forcerotate)
(Robin Gareus)
* A new option to make jack_capture absolutely silent.
(--absolutely-silent) (Robin Gareus)
* Option for recording only while freewheeling. (--jack-freewheel)
(Robin Gareus)
* Total recorded time shown in console, as minutes and seconds.
* Backwards compatible JACK latency API. (Robin Gareus)
* Don't close jack client too early.
* New option: --no-stdin. Works the same way as the old --daemon
option.
* Fix writing to stdout.
* Don't use helper thread when writing to stdout.
* Applied Filipe Lopes' freewheel patch. Do not reconnect ports when
freewheeling.

Dear All,
I want to introduce my fork of FST. It can be treat as successor because it backward compatible. My private goal is to make app for live performance.
My initial changes:
FXB/FXP support
fix for M$ -> Unix paths
remove mute button
bypass button now suspend plugin
use libxml2 for parse FPS files
save midi-maps
MIDI channel filter
button for show/hide editor
use getopt to parse options

A pretty old and terribly overdue JACK MIDI crash bug as been fixed.
Hopefully at last. Ones who've been using the ALSA-MIDI (aka. ALSA
Sequencer) interface exclusively don't need to worry. All the rest
please apply ;)
QmidiNet 0.1.2 released!
Have fun!
QmidiNet [1] is a MIDI network gateway application that sends and
receives MIDI data (ALSA-MIDI and JACK-MIDI) over the network, using
UDP/IP multicast. Inspired by multimidicast [2] and designed to be
compatible with ipMIDI [3] for Windows.

Change-log:
- JACK MIDI in-bound buffering was originally flawed and often the cause
for severe random crashes, mostly due to memory corruption, now
hopefully fixed.
- Changed order of JACK MIDI and UDP socket initialization, hoping the
later is always owned by the current genuine process.
- JACK MIDI interface were sinking all incoming events into the the
first port, now fixed (heads up from Chris Goddard, thanks).
- Make(ing) -jN parallel builds now available for the masses.
- Fixed Makefile.in handling of installation directories to the
configure script eg. --datadir.
- Main context menu simple no-brainer reordering.

Guess what...?
the last of the remnants quietly emerges :)

Weblog (upstream support):

License:
QjackCtl is free, open-source software, distributed under the terms
of the GNU General Public License (GPL) version 2 or later.
Change-log:
- Killing D-BUS controlled JACK server is now made optional, cf.
Setup/Misc/Stop JACK audio server on application exit. (a patch by
Roland Mas, thanks).
- Added include <unistd.h> to shut up gcc 4.7 build failures.
- Make(ing) -jN parallel builds now available for the masses.
- A mis-quoting bug at the command line argument string may have been
crippling the (unmaintained) Windows port since ever, leaving its main
function to start jackd dead in the water, belly down :) now hopefully
fixed (following a mail transaction with Stephane Letz and Mathias
Nagorni, thanks).
- Currently a JACK2-only feature, the JACK version string display at the
About dialog box, must now be explicitly enabled on configure time
(--enable-jack-version).
- A new so called "Server Suffix" parameter option appears to rescue on
the situations where QjackCtl falls short on extra, exquisite and/or
esoteric command line options eg. (net)jack1/2 differences.
- Fixed D-Bus Input/Output device parameter settings, filled when either
interface is selected for Capture/Playback only. (probable fix for bug
#3441860).
- Fixed Makefile.in handling of installation directories to the
configure script eg. --datadir, --localedir, --mandir. (after an
original patch from h3xx, thanks).
- Main window is now brought to front and (re)activated when clicking on
the system tray icon instead of just hiding it.
- Add current xrun count to the system tray icon tooltip, if not zero
(after patch #3314633 by Colin Fletcher, thanks).
Enjoy && Have fun!

On behalf of the entire Rivendell development team, I'm pleased to announce the availability of Rivendell v2.1.4. Rivendell is a full-featured radio automation system targeted for use in professional broadcast environments. It is available under the GNU General Public License.
From the NEWS file:
*** snip snip ***
Changes:
This is a maintenance release of Rivendell. Some of the issues
addressed include:
RDCatch XLoad Wildcards. Several new wildcards and meta-characters
have been added for specifying URLs in RDCatch, including:
$e -- Day of the month, space padded ( 1 - 12)
$E -- Day of the month, unpadded (1 - 12)
^ -- Convert value indicated by following format character to all
uppercase.
$ -- Convert the initial character of the value indicated by the
following format character to uppercase.
A complete list of wildcards can be found in 'docs/datetime_wildcards.txt'.
HPI Compatibility. Updated HPI subsystem to work with the latest
AudioScience driver versions (v4.10.x).
RDLibrary Reports. Fixed a problem where generated reports would
not accurately reflect the current cart filters.
A detailed list of all bugfixes can be found in the ChangeLog.
Database Update:
This version of Rivendell uses database schema version 205, and will
automatically upgrade any earlier versions. To see the current schema
version prior to upgrade, see RDAdmin->SystemInfo.
As always, be sure to run RDAdmin immediately after upgrading to allow
any necessary changes to the database schema to be applied.

Hi all,
I am glad to announce the release of NASPRO 0.4.1.
NASPRO (http://naspro.atheme.org/) is meant to be a cross-platform
sound processing software architecture built around the LV2 plugin
standard (http://lv2plug.in/).
The goal of the project is to develop a series of tools to make it
easy and convenient to use LV2 for sound processing on any (relevant)
platform and for everybody: end users, host developers, plugin
developers, distributors and scientists/researchers.
This is just a small update to NASPRO Bridge it and NASPRO bridges that:
* makes use of LV2 Atom for MIDI events;
* enables LRDF-equivalent bundle installation and automatic
translation of DSSI programs to LV2 presets by default;
* aligns with the unified LV2 distribution.
Enjoy!
