[LAU] Ardour-Rosegarden mixdown

by Louis Gorenfeld

Hi all, I'd asked on this list about this a few months back and didn't receive any replies, and then wrote again but the old server bounced the message. So, I apologize for any excessive repeats in advance. When I mix my tracks down from Rosegarden 5.1 to Ardour .99.3, I've been using a realtime record to a stereo Ardour track. However, I'd like to do a non-realtime mixdown. I've been told that Rosegarden and Ardour are supposed to sync during an export if Rosegarden is an input to a bus, and this will cause JACK to snap into a non-realtime mode. But, when I try this, it just exports silence, and Rosegarden doesn't seem to ever react. Has anyone tried this? Any success? Thanks in advance, Louis

[LAU] rtmix compile errors

by Josh Lawrence

Hello all, I am trying to compile rtmix 0.75 for my pure:dyne installation. Compile passes without errors, but make fails: c++ -DHAVE_CONFIG_H -I. -I. -I.. -I/usr/include -I/usr/X11R6/include -DQT_THREAD_SUPPORT -D_REENTRANT -O2 -fno-exceptions -fno-check-new -c mathexpr.cpp mathexpr.cpp: In function `void SimplifyStr(char*&)': mathexpr.cpp:435: error: ISO C++ forbids initialization in array new mathexpr.cpp:437: error: ISO C++ forbids initialization in array new make[3]: *** [mathexpr.o] Error 1 make[3]: Leaving directory `/mnt/hd2/1/compile/rtmix-0.75/rtmix' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/mnt/hd2/1/compile/rtmix-0.75/rtmix' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/mnt/hd2/1/compile/rtmix-0.75' make: *** [all-recursive-am] Error 2 zsh: exit 2 make I've tried Googling for "mathexpr.cpp", but can't find any information that can lead me to what might be causing this problem. A search on Gmane in our group didn't turn up anything, either. Can anyone point me in the right direction? -- Josh Lawrence http://www.hardbop200.com http://www.joshlawrencetrio.com

[LAU] Another new idea

by Folderol

Once again I'm trying something rather different from my usual style(s). It's still a bit rough round the edges, but I'd be interested in comments. It's only available in mp3 format at the moment. I'm getting a bit embarrassed for webspace :( http://www.musically.me.uk/music/NuToon.mp3 I really must try to think of a title for it. Nothing really comes to mind just yet. -- Will J G www.musically.me.uk

[LAU] SID chip emulation?

by James Stone

Does anyone know of a linux based synth that emulates the sound of the C64 SID chip? I would love to use that sound in some pieces, but I have never been able to find anything very usable. Perhaps something could be used from the libsid/libsidplay libraries?? James

[LAU] ladspa pvoc

by Michael Iber

Hi, I compiled the pvoc-ladspa-plugin successfully, but running "analyseplugin /usr/lib/ladspa/pvoc.so" gives me: "Failed to load plugin "/usr/lib/ladspa/pvoc.so": /usr/lib/ladspa/pvoc.so: undefined symbol: _ZN10DescriptorI10ExaggerateE5setupEv" and consequently the plugin won't be loaded into any host application. Any suggestions? (Suse10.2, gcc (GCC) 4.1.2 20061115 ) Thanks, Michael
