[linux-audio-dev] Re: Project: modular synth editor

by Juhana Sadeharju

Hello. NMEdit was mentioned in my list. I'm in their devel list but it has been quite quiet. I will check Graphviz better in a few days but can one make Quasimodo or Nord Modular type "graphs" with it? In a quick look I saw some composite icons (not widgets?), but I feel Graphviz is not very usable for us. -*- Both the standalone editor and the embedded editor would be needed. Standalone editor could use sockets and shared memory for communicating between the editor and application. Embedded editor could be launch by filling in a callback table and calling the editor: GtkWidget *editor; editor = editor_create(callbacktable); gtk_widget_show(editor); It could be slightly more complex if GTK is not the only supported toolkit. We also could have editor_menu_create() if one wants attach the editor related menu to application's menubar. -*- Should we provide a standard (XML script?) for building module interfaces? New GUI widgets would be included as soon as somebody writes them. This kind of approach would be needed in creating plugin GUIs and environments (a la Logic Audio). Should we allow module author to code the GUI for the module using directly GTK? How GMPI handles the plugin GUIs? I see that we would do an overlapping work here. -*- Assume I have written a module GUI with GTK. I load the calling function to the editor and create the GUI with modulewidget = mymodule_create_gui(); gtk_widget_show(modulewidget); Now, can I trace the whole widget hierarchy starting from "modulewidget"? In GTK, can one attach names to the widgets? E.g., I have a small pixmap of a connector where a cable is plugged in. I want name all these widgets as "connector". Then in the editor I would search all connectors by tracing the widget hierarchy and looking for "connector" names. We need to know where these connectors are located because we want be able to plug the cables in. Alternatively we could describe the locations in a file, but then we would be bound to the fixed shape GUIs. -*- In gtk related mailing lists I have already suggested a general way how to implement a zoom in the editor (Widget Portal). If that is not possible in GTK, then I see no other way than write new widgets with a zoom ability. Regards, Juhana

[linux-audio-dev] Re: Project: modular synth editor

by Juhana Sadeharju

Hello. I would like to clarify that the project originally was not about writing a common modular synth patch editor. The idea was not that we would have a common modular synth patch format. The idea was to have an editor which anyone could take and configure for their own system (audio, graphics). All the whistles and bells would be there to re-implement the existing editors. All individual software would still be individual software having nothing common. Search for the ultimate modular synth system would still continue. It certainly is easier to extend the existing modular synths if the editor supports the features. However, this development could lead to a standard module GUI system. After the project is finished we would have: -Discussions, ideas -Technical information -Example implementations -A code library -Complete editor Maybe. Regards, Juhana

[linux-audio-dev] JACK Release 0.94.0

by Taybin Rutkin

JACK RELEASE 0.94.0 JACK is a low-latency audio server, written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin"). JACK is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation. JACK's webpage is at http://jackit.sf.net . CHANGES: Mostly minor, internal changes. * Added missing extern "C" {} for better C++ support. * Added missing copyright header. * Better placement of watchdog check so it doesn't interfere with freewheeling mode. * Fixed option parsing problems * ALSA driver reports actual samplerate, not requested samplerate. * Handles hardware where playback and capture rates differ better. * Support for native endian S24_3 format used by USB soundcards. * jack_metro example ported to new transport API. * cleaned up prototype declarations for jack_initialize_shm() and jack_cleanup_shm(). * Eliminated calls to jack_error() when jack_client_new() fails because the server was not running. * Eliminated other calls to fprintf() in libjack. * Won't try and compile iec61883 if libraw1394 is below version 0.10.0. * Internal bug fixes. * Updated documentation.

That means you and Daniel are going to help out the Linux Audio Developers on that stand. How is Sounds Expo different from ZKM or LinuxTag? *What* *exactly* are we trying to promote? Shouldn't we all promote and protect the things we value the most - oss linux audio projects? Are private mailing lists and sudden consortiums the way it's done? Marek

"The consortium aims to co-ordinate joint projects between members, collaborate on the promotion of Linux based systems for audio tasks, and provide a single point of contact for both prospective Linux users and industry partners." IIUC it should serve and protect the community and its members. Isn't LAD such single point of contact?

So keeping such projects confidential until "ready", and not accepting a community place although it's been here from 1997 or so isn't childish? Marek

[linux-audio-dev] [admin] user list is members-only....

by Joern Nettingsmeier

hello everyone! there are a number of messages from LAD contributors who are not subscribed to LAU in the LAU moderation queue. my current policy is to reject them, which i hate to do, because they are helpful replies with useful information. the problem is: i don't have the time to check whether the poster has re-sent them already using another (subscribed) account, and if i just accept all postings whose senders i recognize, there will be duplicate messages. so please, LAD patrons: do subscribe to LAU. you can disable mail delivery if you want to reduce the load on your inbox, but you will be able to crosspost. unfortunately, there is no feature in mailman to allow all LAD subscribers to post to LAU, or i'd use it. best, jörn -- "I never use EQ, never, never, never.

[linux-audio-dev] linuxmusician.com: a website of sorts

by Chris Cannam

Quite a long time ago now, Richard Bown and I decided we were going to set up a sort of magazine website for musicians using Linux. It wouldn't be a developer site or a pro-audio site or even particularly a technology site, it would just be a site for individuals who were interested in doing music. We registered the name linuxmusician.com, and then, inevitably, contrived to do absolutely nothing at all with it for the next eighteen months. It became very clear very quickly, as always, that we simply wouldn't have the time to write a substantial amount of material for it. The subsequent appearance of the handy QuickToots site at djcj.org also seemed to reduce the need for some of the content we'd been hoping to write or solicit. Recently though we decided that enough was enough, and that we should just launch the damn thing with the few contributions we could make plus a community article-submission facility and at the least give it the chance to flop gracelessly instead of never being launched at all. So one install of Mambo later, and we present http://www.linuxmusician.com/ At the moment there is one (1) complete article on there, plus two brief stubs of articles; there's a links page with hardly any links yet, and a copy of the bownie.com Guide to Home Recording. We will continue to post stuff that we come up with, but also if you take a moment to register you are then very welcome to submit articles, news, and links. It's not a complete slash/scoop-style community moderation system; for example, there's currently no comment system at all. But we're very open to ideas and concoctions that other people might want to suggest. Chris
