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

Seems >like such an overly-broad generic idea.. audio, graphics, modular >synths, software, hardware, editor ?? Yes, it is generic idea because visual programming (icons + wires) is used everywhere. I planned that our editor would support specially audio related applications: Nord Modular type, Reaktor type, and simpler type editors. Graphics related editor for, e.g., Cinepaint would be much simpler than Nord Modular type editor. The editor would only give the graphical graph/dataflow editor: icons + wires, subgraphs, export/import. People still would have to write software to give meaning to the graph/dataflow. I find it very difficult to code the graphical editors and other GUIs. Mostly I write C code without GUI. Now if there already would be a generic editor available, I would take one and write suitable callbacks, and have the GUI in a few hours. Glade, a GUI builder, can help but it fails badly for what really would be usable. They should go a far beyond the widget level. Note, we do have such graph editors (in PD, in Quasimodo, etc.) but the problem is that they are limited to some particular concept. I want use all concepts in the same editor. Regards, Juhana

[linux-audio-dev] qsynth configure script fails on debian [qt]

by Florian Schmidt

Hi, i just compiled qsynth-0.1.0 and i would lie to report on my findings: On Debian, the qt-libs are installed to /usr/lib/ and the headers to /usr/include/qt3 There's no QTDIR per se. So i exported it to be /usr. This way, the configure script finds the lib, but the following test fails: checking whether QTDIR environment variable is set... /usr/ checking for Qt library... qt-mt checking for Qt library version >= 3.1.1... no; Qt 3.1.1 or greater is required the entry from config.log: ---- configure:1167: c++ -o conftest -g -O2 -I/usr//include conftest.C -L/usr//lib -L/usr/X11R6/lib 1>&5 configure:1157:21: qglobal.h: No such file or directory configure:1161:2: #error Qt library 3.1.1 or greater required. configure: failed program was: #line 1156 "configure" #include "confdefs.h" #include "qglobal.h" int main() { #if QT_VERSION < 0x030101 #error Qt library 3.1.1 or greater required. #endif ; return 0; } ---- Hmm, looking at the commandline to compile this, it cannot work, since the include path is /usr/lib. so i changed this in the configure script: #include "confdefs.h" #include "qglobal.h" to #include "qt3/confdefs.h" #include "qt3/qglobal.h" Then i get an error again: cannot find confdefs.h. So i check my qt3 include dir and it is not there. so i removed the line from the qt3 test program from configure. And now the test runs fine and the program compiles nicely.. My suggestion: Add a --with-qt-inc-dir and a --with-qt-lib-dir switch to the configure script, so "non standard" [though the qt way itself is non standard] qt installations can be found, to. I still wonder where that confdefs header file lives on my computer. gonna start a find / now ;) Maybe there's a more grcefule way to handle this configure problem. /me doesn't know it..

[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

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.
