[LAD] [ANN] a2jmidid version 6 "Indzhe Voyvoda" released

by Nedko Arnaudov

a2jmidid is a project that aims to ease usage of legacy ALSA sequencer applications, in a JACK MIDI enabled system. Homepage with screenshots: http://home.gna.org/a2jmidid/ Tarball download: http://download.gna.org/a2jmidid/ Changes since version 5: * MIDI processing improvements * Handle large number of ports * a2j script (non-dbus-like behaviour for dbus environment) * Allow tweaking through dbus of the hardware port export option * Fix a use of invalid memory * Fix port miss that can occur if port appears during bridge startup Special thanks to Torben Hohn and Paul Davis for their recent work on improving the a2jmidid code. Indzhe Voyvoda was a renowned leader of an armed band of outlaws in Ottoman-held Bulgaria. Eventually, he gave up robbing and began to patronize the poor Bulgarian population. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[LAD] GUI for audio application

by Carlo Ascani

Hi all, I'm a junior developer, interested in GUI developing (and looking for a job hehe....) I wanna put your attention to the state of audio application GUIs under Linux. We have many toolkits to develop a GUI, but none that allows the user to say: "Damn, that's cool!" I mean, all of you know the LinuxDSP audio plugins, they have a GUI that cause a "Damn, that's cool!" but that isn't free software. Another example is libphat, but it's all but a "Damn, it's cool". What i mean is: is there anyone interested in writing a simple set of audio widget that will be: Simple, Good Looking, Skinable? I'm interested, if there's anyone, let me know. I'm free to talk about it. -- Carlo Ascani La politica pratica consiste nell'ignorare i fatti. (Henry Adams) C programmers never die.

[LAD] mx44...2?

by james morris

Hi, Not sure what Jens M Andreasen's email actually is these days, so sending here. I rather like Mx44 and am wondering about adding a couple of features to it? At the moment i'm building it with -DGTK_DISABLE_DEPRECATED and -DGDK_DISABLE_DEPRECATED and search/replacing the deprecated code. 1) a make install target, to install the binary and the patches 2) using ~/.mx44/ to store user created patches 3) a toggle to switch between user/system patches 4) autotools build structure 5) gui enhancements: possibly placing the four panes into tabs, experiment with other layouts which might be more user friendly. 6) non-jack i/o is broken on my system, so i want to remove it. I might have questions about some of the files, and i/o code, but i'm not at that stage yet. cheers, james.

[LAD] OT: gtk rectangle with opacity

by Patrick Shirkey

Hi, Does anyone have an example in c of drawing a gdk_rectangle with opacity in the foreground color? There's several examples in python floating around that use the cairo but I can't find a nice example in c. Cheers. -- Patrick Shirkey Boost Hardware Ltd

[LAD] Setting fonts in pixels rather than points

by Jens M Andreasen

I am trying to fix the size of my UI to be independent of the selected WM theme. I have a gtkrc (based on the "Ia Oya" engine) which will do that - except for the font sizes which will vary dependent on how screen resolution is set globally. One work-around I have found is to use a font that has only one size. Of that kind I have found three: "Terminal" (medium sized, looks a bit like a flattened "9x15"), "Teletext" (like "Terminal" but wider), "Outcast" (small, "Tek"-like slanted) and "Caption" which is again like "Terminal but twice the size and more polished. Are these fonts standard in any distribution? Or a result of the dependencies of whatever packages I might whimsically have happened to have currently installed? [Dots per inch makes little sense when the target could be a cinema sized 800x600 projector as well as a handheld with similar resolution]

[LAD] gcc and pointer aliasing... missing optimizations in some cases

by torbenh

hi... i discovered yesterday, that gcc cant optimize something like: ----------------------------------------------------------------------- class Ramp { private: float _phase; float _omega; public: Ramp(); float process() { _phase += _omega; return _phase; } }; Ramp osc_block; int process( jack_nframes_t nframes, void *arg ) { int i; float * __restrict__ buf = (float *) jack_port_get_buffer( out_port, nframes ); for( i=0; i<nframes; i++ ) { buf[i] = osc_block.process(); } } ----------------------------------------------------------------------- the __restrict__ on buf is not enough to convince gcc that writing to buf[i] doesnt clobber _phase or _omega; i am trying to make a case here, that something stronger than __restrict__ is needed which allows the programmer to state that a pointer really doesnt alias to anything. of course the gcc guys say "wont happen" ... so the question is whether we have enough need for this in the dsp scene... and maybe some political power ? am i totally wrong and such idioms arent of much use ? -- torben Hohn

by m.wolkstein＠gmx.de

hello lad, i decide to forward this mail from hydrogen-devel-list to lad-list. beta testers are welcome. greetings wolke Start weitergeleitete Nachricht: Datum: Thu, 24 Dec 2009 01:07:42 +0100 Von: Sebastian Moors <mauser(a)smoors.de> An: hydrogen-devel(a)lists.sourceforge.net Betreff: [Hydrogen-devel] Hydrogen 0.9.5-beta1 released Hi! just to make sure that nobody gets bored over the Christmas holidays we decided to release the first beta version of hydrogen 0.9.5 as a special gift for everyone.. This release is meant as a first "public" preview and mainly for testing purposes. Here's a quick list of some new features: - non destructive sample editor ( requires rubberband-cli for advanced features ) - a timeline - instrument midi out - better support for non-ascii filenames ( changed XML-Parser from TinyXML to QtXml ) - piano-roll editor - export to ogg, aiff and flac - ... The sourcecode is available here: https://sourceforge.net/projects/hydrogen/files/Hydrogen/0.9.5%20Sources/hy… Binaries will be available for Ubuntu 8.04 / 9.04 / 9.10 and debian unstable at the sourceforge file-module in some minutes.. Please report crashes and other glitches here: http://www.assembla.com/spaces/hydrogen/tickets Merry Christmas to all of you and enjoy your holidays! - Sebastian

[LAD] phasex-0.12.0-pre1

by William Weston

Announcing phasex-0.12.0-pre1: The pre-release is here. It's stable. It builds cleanly. No build errors or warnings. No runtime errors or crashes. No glitches. If no bugs are found in the next week, then this code (with the addition of some brand-new patches) will become the stable release. Changes since phasex-0.12.0-beta4: - Build system overhaul. GCC version detection for better arch- specific optimization (compiles clean with gcc-3.4.x or higher). Atom builds fall back to next-best optimizations for GCC < 4.5.x. New --enable-32bit and --cpu-power-level= flags and better user variable handling for ./configure. Missing -lpthread in link phase is fixed. - Velocity control for the amplifier. Better aftertouch handling. - Scheduling policy defaults to SCHED_RR, and can be changed in the settings at runtime. - Broken ringbuffer code has been fixed. No more glitches (unless you have actually run out of CPU). - Theme loading has been fixed. Now properly detects if the nodoka theme engine is installed, and quietly falls back to an engineless theme. - Fullscreen and Maximize interaction have been fixed. - New command line options: -m (--midi-channel=), -f (--fullscreen), and -M (--maximize). Loading a patch by name or by program number on the command line now finds the appropriate patch in the patchbank. - The lurking patch name corruption bug has been fixed! - And more. See the ChangeLog for details... Download phasex and hear for yourself... http://sysex.net/phasex/ Alternatively, you can utilize the git repositoty: git clone http://sysex.net/git/phasex.git Cheers, --ww

[LAD] A note to the Phasex coder

by Ralf Mardorf

I've got a new monitor. When running Phasex on my new Monitor the first time, I was able to see, that it would be possible to use Phasex with my old monitor too, but using the old monitor I wasn't able to see this and it was impossible to use the GUI to change the settings ;). It would be better to have a default for the fonts and the GUI display that fits better to old monitors. :) Ralf
