In light of the interesting discussion on sample rates I propose a music
competition among LAU around production of music pieces with quality
considered 'low' by current dominating professional/audiophile standards
in the digital domain:
Specifics to be discussed, but I would start with the following:
1. Final piece shall be delivered with a maximum sampling rate of 32kHz.
Lower sample rates .allowed.
2. Final bit depth of the file shall not exceed 8 bit.
- Possible variations/additions to this restriction:
- allow dithering?
- allow 4/8bit codecs (e.g. ADPCM, ulaw)?
- mono/stereo?
- simply impose a max duration and max filesize (but keep sr and bit
thresholds... and variations..)?
- Participants shall strongly focus on exploring and exploiting the
imposed limitations in a creative and artistic way
Other specs, voting mechanisms, competition arrangements, prizes, ... ???
Ciao,
Lorenzo.
Once again, it's springtime.
Once again, the planet revolved and stepped forward against its mother star.
Hence the <em>three bees</em> release... it won't be that far fetched if
you find this naming a deliberate pun riddle indeed--the wise will know
already while the clueless will get it sudden in a couple of days ;)
Well, no big surprises nor earthshaking features are being here pitched
then, just some small and otherwise humble improvements and fixes and
what not.
Nevertheless and not just for the record that is, it marks the day of a
long overdue and severely procrastinated <em>beta</em> phase release.
Whatever. It's dang official now: one step closer to <em>omega</em>, no
doubt ;)
Contrary to, maybe, newer generations, I <em>always</em> strive to say
the least. As to say about literal face-value meaning, as written and
read on timeless textbooks, it's all left in between the lines or, this
part is the one I like most, left over as an exercise--in some kind of
healthy masochism, perhaps :).
No wonder,
Qtractor 0.6.0 (byte bald beta) is now released!
Release highlights:
* Plugin automation high resolution option (NEW)
* Plugin 'About' page (NEW)
* Native DE dialogs option (NEW)
* Follow play-head slack time (NEW)
* MIDI RPN/NRPN 14-bit controllers input (FIX)

Change-log:
- New user option added: on whether to save plugins automation values
with higher resolution as possible, using 14-bit NRPN: cf.
View/Options.../Plugins/Experimental/High resolution plugin automation
(default=off).
- Generic native plugin dialogs now shows an additional "About" last
page where authorship credits are due.
- A new user preference option is now in place for whether to use
desktop environment's own native file requester/browser dialogs
(View/Options.../Display/Dialogs/Use native dialogs).
- A bit of slack have been introduced to put "Follow Playhead" (aka.
auto-scroll view mode) on hold, while doing in-flight selection edit moves.
- Fixed some user interface related annoyances while on the MIDI
Controllers mappings (ie. View/Controllers...).
- Fixed port origin on MIDI RPN/NRPN 14-bit controllers input.
- A discretionary plug-in unique identifier have been devised for when
more than one from the same type are inserted on a bus or track chain,
avoiding destructive clashing of automation data.
- Horizontal scrolling shift+mouse-wheel direction now reversed.
- LV2 Dyn(amic)-manifest support is now optional (default=off); cf.
View/Options.../Plugins/Experimental/LV2 Dynamic Manifest support).
- The following options, although decieved on View/Options... as global
configuration options, were always and still are proper session instance
properties: (JACK) Transport mode, MMC mode, MMC device, MIDI SPP and
MIDI Clock modes, are now shown there reflecting the current open
session state.
- A couple of run-time circumventions have been hacked in, both strictly
related to when NSM session management is in charge: 1) the new session
template feature is disabled (was aborting initial NSM new client
additions); 2) the native (as from the desktop environment eg. KDE) file
browser/requester dialogs are disabled (were taking too long to list the
current directory on first time invocation).
- Update current automation/curve nodes selection while changing
horizontal (time axis) zoom levels.
- One liner's attempt to make it consistent behaviour on resizing and
moving multiple selected notes or events while on the MIDI clip editor
(aka. piano-roll; after a ticket request from Daniel MacDonald aka.
danboid, thanks).
- Introducing tiny quarter-note/crotchet/seminima/beat icon on all
snap-to-beat selection items get a new icon :).
- Corrected some audio buffering boundary conditions that were causing
dead-loops/freezes while merging some audio clips.
- Session auto-save period was chronically reduced to one third of its
user setting; non critical but fixed now.

Thanks to this thread I looked up Jeff Glatt.
Found this at top -- Heh!!

Lesser life forms communicate in more primitive, less artistic manners
such as barks, chirps, roars, or any of the many human verbal
languages in use throughout the globe. But, gods communicate using
MIDI messages. Even a picture, whose value is often equated to a
thousand words, cannot match the scope of emotional and intellectual
power unleashed by a stream of MIDI messages. But, try to tell that to
the visual-and-print-fixated, tone-deaf heathen who infest this
planet...
--------------------
Reading through I find a glimmer of hope that I may move on from
perennial noob status
So thanks!

Hi,
I don't know who is "j_e_f_f_g" and how to reach him by mail, so hopefully he
is subscribed to this list.
j_e_f_f_g: you have been editing every page in http://wiki.linuxaudio.org/apps
for some time. The revision below is wrong. vmpk doesn't "display notes on a
staff". Including the program in the "Score recognition" category is
misleading.
Perhaps your revision comes from watching the demo video on YouTube, without
realizing that it involves another program (musescore) displaying and playing
a score, while connected to vmpk which highlights the piano keys when it
receives MIDI events. You may replace musescore by another MIDI player. Here
is a similar demo involving kmidimon instead: http://youtu.be/3TGNSYKjEtg
That is one use case for vmpk, but for most people the main feature would be
creating MIDI events.
Regards,
Pedro

Hi there.
Can you help me with this doubt, please?
I have got this problem, but on my mac-mini:
http://jackaudio.org/macbook_distortion
I'm working with a debian wheezy distro and can get only clean sound forcing the 16 bits on jack 2.
No problem working via alsa but without jack.
Instead I have tried some live dvd audio oriented distros on the same computer and then all works perfect, also with 32 bits.
Any idea about what I must change?
Thanks a lot!
hallo,
alexandre prokoudine just 'announced' the cursynth at the LAU list
yesterday.
first of all, thanks for your effort on developing this nice looking
jackified synth.
trying to compile, i get an error about missing 'soundcard.h'.
i am using this configure line:
./configure --prefix=/usr --with-jack --without-oss --without-pulse
and also i tried this one:
./configure --prefix=/usr --with-jack --with-oss=no --with-pulse=no
but both times it looks to me that oss and pulse are considered to be
compiled.
are this switches non functional?
my system:
nowhiskey@murija7:~/Desktop/src/cursynth-1.4$ uname -a
Linux murija7 3.13-5.slh.4-aptosid-686 #1 SMP PREEMPT Tue Mar 4 21:17:55

i tried to install everything what i found to have to do with
soundcard.h but it does not work.
here the error:

Hi all.
I was wondering if anybody has any light they can shine on compatability of either of these two external, USB audio interfaces:
Sabrent USB-SND8 http://www.sabrent.com/category/audio/USB-SND8/
Vantec USB External 7.1 Channel Audio Adapter http://www.vantecusa.com/en/product/view_detail/439
I am currently travelling in India with nothing but the onboard sound of my laptop and would like to get something with 4 channel (2 stereo pair) outputs, at least for use with Mixxx. These both are available at a reasonable price through Amazon India...
It's been hard to find much online, and what I have seen has been slightly contradictory (plus it can be painful trying to search and read posts when the internet is quite as interminable as it can be here!) Any experiences, or even any better searching ability and summarisation of the findings, would be very much appreciated.
Regards, Dale.
Hello,
Although I was a programmer a long, long, time ago in a
company far, far away, I cannot seem to get the hang of complicated
Linux packages which require complex actions just to get an
"app installed" on a Linux machine.
I have an Ensoniq ESQ1 which just seems unable to interact
with any WIN/OS-based software, despite what people tout
as easy-to-use programs. I have tried to download and install
Linux MIDI items, and almost all of them require complex configuration
even to get them into the system. All I really want to do at this
point is get an application running which will upload and download
patches; nothing yet in the way of realtime operations such as recording.
A big part of this appears to be the MIDI hardware used as an
interface; most of those "apps" expect to find the classic
Roland MPU401, and those are scarce as could be these days.
The old apps apparently cannot recognize anything based
on USB ports.
Yes, I can do a make/install sequence, but those resulting
error messages usually point to matters beyond my understanding
such as GTK+ levels, " missing [.so] files", etc. Those usually stop me
in my tracks, and then things don't go any farther.
Ideas, anyone?
Brian
Hi,
I will got about 100 stereo wav files mixed hopefully in similar way
(loudness).
I need them process to meet ebur128 specification.
True peaks -3dB
RMS -23dB
Any chance to do it as batch process?
Result quality is critical as material will be broadcast on TV.
best
mira
