PHASEX-0.11.1 contains fixes for the segfault issues some users have
seen with version 0.11.0. Special thanks goes to Adam Sampson for
tracking this down, and to the rest of you who sent in bug reports.
Upgrading to 0.11.1 is recommended for all users, since it appears
that this bug will corrupt memory used by the synth engine even if
it doesn't trigger a segfault.
As usual, source tarballs and FC6 RPMs (src, i386, i686, and athlon)
are available at:
http://sysex.net/phasex
Thank you for your continued support. Here's to happy music-making
under Linux!
Cheers,

Version 0.11.0 of the [P]hase [H]armonic [A]dvanced [S]ynthesis
[EX]periment is ready for download (source tarball and FC6 RPMs) at:
http://sysex.net/phasex/
This release contains many fixes and improvements and is highly
recommended for all PHASEX users. Here's a brief list (see the
ChangeLog for more details):
Engine fixes: Filters and oscillator bandlimiting are now properly
tuned (taking into account filter oversampling) and work as
documented. Calculations for lookup tables are more accurate. The
envelope curve has been improved and sounds a lot more natural.
Additional bugfixes are found in the ALSA MIDI startup and JACK
shutdown code.
Engine optimizations: A few simple optimizations have been worked
out, with an average of about 30% CPU cycle reduction per voice, and
about 30MB of memory overall. For custom builds, the engine can
easily be fine-tuned in phasex.h, and the --enable-arch= configure
option supports all x86 CPU types supported by gcc-4.1.2.
Improved patch bank: The entire bank is preloaded into memory.
There is now support for patches in alternate directories. The
memory modes have been reworked (and finally documented in the
runtime help system). Multiple patches from a directory may now be
loaded into the patch bank at once.
GUI updates: Special thanks goes out to Pete Shorthose for providing
the initial backing store code and some pearls of GTK wisdom to make
window redrawing and tab switching faster and smoother. For those
of you who haven't done so already, now would be a good time to
enable backing store in your X server.
Knob and control updates: Scroll wheel support has been added to
the knobs and alternate controls. Middle-click centering of knobs
is more responsive. The cumbersome combobox lists have been changed
to detent knobs with clickable value labels.
Parameter locking: Parameters can now be locked down to their
current values, effectively blocking out program changes, patch
loads, and MIDI controller messages on a per-parameter basis.
New settings: The base A4 tuning frequency and backing store can
now be set in the preferences dialog.
Cheers!

Hi,
Announcing the latest release to the quicktoots archive.
DJing with Freewheeling & Hydrogen.
DJing is an artform and freewheeling with JACK on Linux makes it
possible to amaze your audience with live remixes of rare cuts and
hidden gems that when put together produce sample Heaven...
Ringheims Auto shows us how it's done.
http://quicktoots.linuxaudio.org
As always we would love to have more submissions on new ways to use the
latest tools. If you are interested in having your name up in lights let
me know.
-----------------------
Background:
The purpose of the Quicktoots are to provide a community resource of
informative guides for using Linux audio applications.
The Quicktoots are the brainchild of Dave Phillips the man responsible
for the most comprehensive webpage devoted to Linux audio applications.
The Linux Sound and Midi page. This has now been taken over by the
community and moved to the Linux-Sound Application Index your one stop
resource for Linux sound software.
http://apps.linuxaudio.org/
If you are in the position to link to any of the quicktoots please link
to the main page. That way we can keep more accurate statistics on the
amount of people viewing the pages.
If you are interested in contributing to the Quicktoots please let us
know. All work must be submitted me and we I will give advice or make
changes to ensure our publishing standard is met. If you are not able to
send html don't worry because I am willing to format any braindumps.
Enjoy.
-----------------------
Cheers.

Mammut 0.60
===========
Mammut will FFT your sound in one single gigantic analysis (no windows).
These spectral data, where the development in time is incorporated in
mysterious ways, may then be transformed by different algorithms prior to
resynthesis. An interesting aspect of Mammut is its completely
non-intuitive sound transformation approach.
*Homepage:
http://www.notam02.no/arkiv/doc/mammut/
*Screenshot:

Changes 0.59 -> 0.60
-Updated source to work with Juce 1.44. (later or earlier versions of
juce might not work with this version of mammut)
-Fixed a couple of ugly bugs in the progress bar code.
-Set moving camera to be off by default. Moving camera seems to stall
mammut when using newer juce's. :-(
Snd-ls v0.9.8.1_beta
====================
Snd-ls is a distribution of Bill Schottstaedt's sound editor SND.
Its target is people that don't know scheme very well, and don't want
to spend too much time configuring Snd. It can also serve
as a quick introduction to Snd and how it can be set up.
(Its named beta, because it hasn't been tested that much. But I think it
should work very well. However, a new non-beta version is going to be
released quite soon with some additional fixes.)
Changes 0.9.7.12 -> 0.9.8.1_beta
-Fixed bug that caused snd to fail starting if no previously used
soundfile was opened during startup.
-Updated Snd from 8.4/12.9.2006 to 9.3/30.7.2007. Many important fixes.
-Another attempt at fixing the rt_readin_tag startup bug.

Hi,
I have some multi-threaded audio software that passes data around
using pointers to data structures. However, I'd like a more
generalized message passing system. The only requirements are that it
cannot block the sender or receiver (they are considered soft
'real-time'), and also that multiple senders should be able to send a
message to the same receiver at the same time (which makes
non-blocking circular buffers a difficult approach). I'm thinking of
designing something that uses atomic_ops to implement quick locking of
portions of a message queue.
Anyways, my idea is to use something like OSC for message passing, but
without the "path" part of the OSC address. (That is, the path is
already resolved, since threads share memory..)
Does anyone know if something like this has been done previously?
Ideally it would easily scale to inter-process communication, if in
the future I wanted to turn my threads into processes. (Another
reason for basing it on OSC..)
Does any of this make sense?
Basically I've been running into a lot of shared-memory threading
problems, which in retrospect should have been expected and avoidable
if I'd spent more time designing my message passing system. (At the
time I hadn't heard of the atomic_ops library.)
I might have designed the whole system to use timers instead of
threads and avoided a lot of headaches, but I wanted the threads to be
splittable across CPU cores. (Which arguably is a good reason to use
processes.. admittedly the whole thing is starting to point me towards
the "threads are a bad idea" camp.)
Cheers,
Steve

"Anything your mind can see you can manifest physically, then it will
become reality" - Macka B
I have a problem with a a project I am helping out with (aldrin),
which uses rtaudio version 3.0.3 for jack/alsa/oss handling.
When aldrin starts, it calls libzzub to detect all possible sound
input/output, and then selects the best one (defaulting to jack
if it is running). This is working fine on my system if I have
selected a sub-device from my SBLive card as the sound
input/output device (hw:0,3 works fine). However, if I select the
default jack output (hw:0), I get loads of xruns when aldrin
starts, then jack dies. Doing some further testing, if I disable
detection of alsa after libzzub successfully finds a jack device,
then hw:0 will work fine without any xruns, so it seems that
there is some conflict between jack and alsa.
Lastly, I noted that if I select hw:0,3 as the output for jack,
then libzzub/rtaudio does not pick up hw:0,3 as a valid alsa
output (presumably correctly assigning it as a jack output),
whereas if I am using hw:0 as the output for jack, then hw:0,0 is
also detected as a valid ALSA device.. this makes me think the
xruns are caused by some conflict.
The lead dev for libzzub is not happy with my patch to libzzub
not to detect alsa if jack is found, and would prefer a fix to
the rtaudio code. I am not really sure where to start with this,
since I am not 100% sure what is going on. I would really
appreciate it if anyone could help with this..
Best wishes,
James
This brings plugin in sync with latest lv2 (changed uri, double srate, header)
LV2 Simple Sine Generator is very simple plugin, generating sine when
feed with notes. It should load in any host supporting midi port LV2
extension, i.e. elven, ingen, lv2_jack_host and zynjacku. Plugin should
be usable for testing basic synth functionality and as simple example
synth plugin to start with if you want to code your own LV2 synth
plugin.

Hello all,
I'm currently developing some resampling code, and would
appreciate your opinion on the quality of the results.
On my website <http://www.kokkinizita.net/linuxaudio>
you will find four files resampled from CD to 48 kHz.
If you have golden, silver or unobtainium ears and some
time, please listen to these files on a good system
(without resampling), and report your impressions (not
to the list but to the address provided on the page).
I'll provide a summary of the results in a month or so.
Many thanks,
