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

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

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

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

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
