[linux-audio-dev] jack.udp and synchronisation

by Asbjørn Sæbø

jack.udp may be used to transmit audio between two computers, each computer running their own jackd. My understanding, based upon earlier threads in the linux audio lists, is that to avoid xruns due to clock drift in this situation, the sound cards of the two computers must be synchronised in some way, e.g. using word clock. Is this (still) correct? Or has jack.udp been developed to include synchronisation? (On a side note, it seems that Rohan Drape's web pages that are linked to from the jack pages, http://www.alphalink.com.au/~rd/sw/jack.html, have disappeared.) Asbjørn Sæbø

[linux-audio-dev] Gerard van Dongen/Gilcher 1967-2006

by derek holzer

Gerard van Dongen/Gilcher passed away on Friday the 4th of March, after a brave battle with colon cancer. Gerard worked as a composer, musician and computer programmer in Rotterdam as well as played live with many improvisational and electronic musicians in the Netherlands including Bart Maris, Tom Wouters, Joe Williamson, Henk Bakker, Peter van Bergen and Ann LaBerge. He performed solo-concerts with electronics and/or piano compositions and played for numerous dance and theatre productions, produced radio-plays for the internet, and was a technical designer and software programmer for multimedia theater. Gerard was also an active member of the Pure Data and Linux Audio Developers communities, and contributed code for the user interface of the Ardour project. Gerard kept a very positive outlook throughout his illness, and he will certainly be missed. Marie Louise Gilcher has organized a memorial service for Thursday, 9 March at the "Crooswijk" Cemetery in Rotterdam. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 118: "Make what's perfect more human"

[linux-audio-dev] a bit off topic: GUI-lib-programming (how does it usually work?)

by Julien Claassen

Hi! I know, this may be a bit off topic. But I've a dificulty: I'm currently programming a textbase "GUI"-lib. I want the programming API to be similar to on of a real GUI-lib (gtk, you name them). Now I'm wondering, there are menus. Menus have menuitems and if you click on one, something should happen. How is this "something should happen" part usually done? - I thought of the java-apporach, deriving your own menu-class. But it doesn't feel right. I have my dificulties with trying GUI-libs myself, for I'm blind. I could write some code, but wouldn't know, if it works, like I planned. Any thoughts, help on this, anyone? I would be greatful! Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net - the Linux TextBased Studio guide

[linux-audio-dev] Creating an api for an exsisting project

by jjbenham＠chicagoguitar.com

I am working on project that does not have an api. I was wondering where to find information on building an api. We have a plugin system but the user needs the entire source if they want to build a plugin. The project I am talking about is Denemo (A gtk frontend to lilypond). Jeremiah

[linux-audio-dev] [ANN] Rhythm Galaxy vol. 1 drum/percussion sample library

by Artemiy Pavlov

Dear Linux audio software users and developers, many of you may know me - a sound designer behind many free sounds I keep on making for Hydrogen rhythm machine and other samplers. Now I am pleased to announce Rhythm Galaxy vol. 1 - an all-new sound library which boasts a huge load of drums, percussion and effects - from analog and digital emulations to brand new, amazing sounds. It is a low-cost but very high-quality library which delivers just the right sounds for various styles. Rhythm Galaxy vol. 1 includes over 250 world-class, superb sounds which satisfy the needs of professional composers and music-making lovers who have been searching for fresh, unique and inspiring material. All sounds are totally original material, they have been created completely from scratch, using Roland Fantom-S, V-Synth and VC-1 synthesizers, Krok 2401 analog vocoder and also ALSA Modular synth. Rhythm Galaxy is available in two formats: - .WAV files grouped in folders ("Kick", "Snare", etc.) - suitable for any hardware/software sampler - Hydrogen drum kit with all 256 sounds (will work only in Hydrogen 0.9.4 sound library manager). Sound demo: http://soniccharger.com/media/demos/Rhythm_Galaxy_1_demo.mp3 Specs and complete sample list: http://soniccharger.com/media/manuals/Rhythm_Galaxy_manual.pdf More info: http://store.rolandclan.info/?action=catalogueViewItem&category=4&id=RGALAX… You can also read more about me and my works at http://sineshine.com.

Also check out http://www.gobolinux.org/abstk/ which supports ncurses and Qt back-ends.

[linux-audio-dev] Shelljam: Help Wanted!

by Carlo Capocasa

Hi, I'm Carlo and I started out Shelljam to provide a way of using any standard computer hardware as an input device to make music with. Uses like altering sounds with joysticks or simply playing chords on keyboards are examples really great uses that come to mind, but there is no inherent limitation. Currently, the most important things that need to be done with Shelljam are SCHED_FIFO realtime implementation and possibly threading implementation (I suspect the threading gains would only start to get visible when a large number of devices are used at once). Personally I would like to minimize my time spent coding and maximize my time spent producing music, although I have a fairly deep insight into C++ and I can work closely with you to produce a Free Software application that has the potential to create a whole movement of young and/or open minded people to enrich our Free Music landscape by reducing the entry cost to produce extremely good-sounding music. Please contact me at capocasa :-:-:AT:-.-.- gmx :--DOT-.-.- Net if you're at all interested! Carlo

[linux-audio-dev] [ANN] Qsynth 0.2.5 released!

by Rui Nuno Capela

Greetings, So here comes the time for another public release of the (cute) FluidSynth Qt Interface: Qsynth 0.2.5 is out! Just as one can read from the change log: - New dial-knob behavior now follows mouse pointer angular position, almost similar to old QDial, but this time avoiding that nasty and rather abrupt change on first mouse click. - By simple use of widget subclassing, the value/position of any dial knob can now be reset to its default or original position at any time, by simply pressing the mouse mid-button. These default value positions are just committed to current dial values when switching engines and/or closing the application. - Optional specification of alternate fluidsynth installation path has been added to configure command arguments (--with-fluidsynth). - After some source code tweaks, a win32 build is now possible (instructions will be provided on demand :) - Bank offset finally gets its due effect, while on the channels and channel preset selection dialogs. Regretfully, the soundfont bank offset feature has been lurking ever since its inception, but now its live and hopefully effective. - A new fancy widget has arrived, qsynthKnob, with some modifications to replace the actual *ugly* QDial widgets in the main window. This widget is based on a design by Thorsten Wilms, formerly implemented by Chris Cannam in Rosegarden, and finally adapted and brought to Qsynth by Pedro Lopez-Cabanillas. Thankyou all. Available from the usual places: http://qsynth.sourceforge.net http://sourceforge.net/projects/qsynth Enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[linux-audio-dev] [ANN] QjackCtl 0.2.20 released!

by Rui Nuno Capela

Greetings, So here comes the time for another public release of the (cute) JACK Audio Connection Kit - Qt Interface: QjackCtl 0.2.20 is out! Just as one can read from the change log: - Server path setting now accepts custom command line parameters (after a kind suggestion from Jussi Laako). - The internal XRUN callback notification statistics and reporting has been changed to be a bit less intrusive. - Patchbay socket dialog gets some more eye-candy as icons have been added to the client and plug selection (combobox) widgets. - Connections and patchbay lines coloring has changed just slightly :) - New patchbay socket forwarding feature. Any patchbay socket can now be set to have all its connections replicated (i.e. forwarded) to another one, which will behave actively as a clone of the former. Forward connections are shown by vertical directed colored lines, and can be selected either on socket dialog or from context menu (currently experimental, only applicable to input/writable sockets). - Optional specification of alternate JACK and/or ALSA installation paths on configure time (after a patch from Lucas Brasilino, thanks). Available from the usual places: http://qjackctl.sourceforge.net http://sourceforge.net/projects/qjackctl Enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

Re: [linux-audio-dev] Errors trying to build dssi-vst 0.4 ... anyhelp?

by Chris Cannam

Yes, but I realise I was misreading the error (it was from the linker, not the compiler). How about an extra "-lpthread" in LDFLAGS or whatever in the Makefile? Chris
