64bit linux audio was Re: [linux-audio-user] The best distro for music creation

I'm thinking of putting together a new computer, and am thinking that going down the 64bit road might be a good idea. I would like to play around with audio on this machine however so i wondering if there are any "gotcha's" to doing this sort of stuff on a 64 bit machine, for example any of the major apps (jack, ardour, etc.) not running well on these platforms? (I think in principle there's no reason why they wouldn't, however I have run linux on an ibook for the last few years and have occasionally had endian issues in the past with some applications, just wondering if there are equivalents for this sort of problem in porting 32->64bit. I know nothing about the state of linux on 64bit so this is possibly a stupid question, if so apologies :) Also wondering what people's experience with 64studio is? Cheers.....Steve

I've got to say that I had no problems in this regard. Plug it in and it showed up. Throw some files on it and grab others off it. Unmount it, plug in a different one, and it shows up, too. I've done this in Ubuntu Breezy with five different USB drives. This was on a standard fresh install of Breezy to an ordinary desktop machine. Now, if the owner of the directory on the USB drive was different than the user doing the moving on the Breezy system, that's a different story... I've had to change owners of folders or permissions at times, but it's supposed to be like that, isn't it? -- Renick Bell http://www.the3rd2nd.com

[linux-audio-user] simple ZynAddSubFX question

by Julien Claassen

Hi! As some of you know I'm blind, but I wanted to show ZynAddSubFX in all its GUI-splender to a friend of mine. Can anyone tell me how to load one of the example banks? All we were able to do was to test some reverb-effects with- I believe - sinewaves. The system is SuSE 9.3 ZynAddSubFX 2.1.1 (I looked up the examples and found them in /usr/share/ZynAdSubFX and this is in the searchpath of the program. I just said it to state that all seems well with the installation. Thanks for a newbie-friendly discription... :-) 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-user] Java Ambisonic b-format player

by John Ouzts

Particularly for the Gentooists out there..... I downloaded and installed Roger Klaveness' Java ambisonics _player_ (not a plugin!) on Gentoo Linux for AMD64 according to Roger's very complete instructions: http://klaveness.info/roger/ambplay/ (Since the recommended Sun JDK 1.5 is not yet available for regular installation on Gentoo, I used the alternate axxo overlay, which installs dev-java/sun-jdk-1.5.0.05-r1along side the blackdown-jdk-1.4 default.) This alpha project already offers more than just the basics of an excellent, open source, cross-platform ambisonic player. It is known to work on Windows XP as well as Gentoo Linux. It plays 4 channel (b-format) flacs, as well as a wide variety of higher order Ambisonic and binaural material in several file formats. Memory and CPU usage is very reasonable while uncompressing and playing 4 channel flacs. This is real SURROUND sound, not 5.1 movie sound effects. The player decodes to as many as 12 speakers including some on the vertical axis. The success of this player has created a problem for me, however. I normally feed the S/PDIF output of my RME Digi96 PAD into my Panasonic SA-XR70 digital receiver. Now I need to feed at least four channels, not just a stereo pair, to the receiver, which has HDMI inputs for multi-channel for DVD-Audio players. (Ever heard of a sound card with an HDMI output?) My current theory is that I need to use the ADAT 8 channel output of the Digi96 to feed some sort of external converter that will make a 4 channel MPEG2, DTS or AC3 feed into a single S/PDIF or Toslink cable for me, since I don't want to go to analog only to be converted to digital again to feed the Panasonic's digital power amps. Does anyone in Linuxland know an elegant way to solve this problem? John

[linux-audio-user] joystick => midi

by Atte André Jensen

Hi I have a usb joystick (Logitech Extreme 3D pro) that I'd like to be able to use for controlling stuff in my synth (om). Is it possible to have it show up as an alsa device? If so how? I don't know too much about joysticks in the first place, but it seems to be connected to /dev/input/js0, at least "cat /dev/input/js0" outputs garbage when moving the joystick... Thanks in advance... -- peace, love & harmony Atte http://www.atte.dk

Or * Add one line at end of your file "/etc/hotplug/blacklist". To do it, open a terminal window, login as root and enter: # echo "usb-midi" >> /etc/hotplug/blacklist Next time you boot the computer, the module "usb-midi" won't be loaded and your keyboard controller will be driven by ALSA. There is a diagnostic script to debug ALSA problems here: http://alsa.opensrc.org/aadebug Perhaps you would like to run it, before and after, and tell us it this helps. Regards, Pedro

[linux-audio-user] Behringer DDX3216 Midi to run Jack?ARdour

by studio-64

Hi All Well it's time for this Musician to bite the Midi Bullet! I have Endirol Midi to USB and it seems to work, as I managed to get something into Rosegarden ( I could see data but it made no sound, I dont think I had anything set for output, like a keyboard) The DDX has Midi out and controlls for play stop and all the rest so I assume it should be able to control Ardour/jack. Anyone tried this? If so please mail me any pitfalls/Advice. Cheers Bob Bearmusic hearmymusic.co.uk <http:www.hearmymusic.co.uk>

The solution came after copy from the fst-1.7/ardour build folder: - the SC* files : fst-1.7/ardour/SConstruct to the build directory of ardour-0.99 and fst-1.7/ardour/gtk_ardour/SConscript to the ardour-0.99/gtk_ardour build directory -the vst directory created during the compilation of fst-1.7 and the fst.h file to the build directory ardour-0.99/libs/ardour . After try your advice,It did'nt work giving diferents error messages. I tried again as the first time ,wihtout copying fst.h to /usr/local/include and the last error : /libs/ardour/audioengine.cc:32:17: error: fst.h: No such file or directory libs/ardour/audioengine.cc: In function 'void _thread_init_callback(void*)': libs/ardour/audioengine.cc:87: error: 'fst_adopt_thread' was not declared in this scope scons: *** [libs/ardour/audioengine.o] Error 1 scons: building terminated because of errors. /made me think that scons was looking for fst.h at libs/ardour/ folder inside the building place. After this ,a similar error looking for vst/AEffect.h file in the same place: / libs/ardour/fst.h:26:25: error: vst/AEffect.h: No such file or directory libs/ardour/fst.h:58: error: expected ';' before '(' token libs/ardour/fst.h:89: error: 'audioMasterCallback' has not been declared scons: *** [libs/ardour/audioengine.o] Error 1 scons: building terminated because of errors./ after copy that folder everything went fine. The next step I did was create /usr/local/lib/vst folder and put inside the vst.dll files,but launching Ardour as root is needed the first time,due to the write acces of that folder.After this I open some vstfx that work with very good performance (ambience reverb and nomad factory free sweeper) Thank you very much and best wishes from Spain. Saludos. Cheers. -- Carlos.

[linux-audio-user] Problems with Roland PC-300

by Chris Norris

Hi all - I would appreciate if someone is able to help get my Roland PC-300 midi keyboard controller to work. The short problem seems to me that although the keyboard is being recognised via USB OK, it is not being correctly/completely identified by ALSA. When I plug it in I get in my system log: Nov 28 17:17:57 dukla kernel: usb 3-2: new full speed USB device using uhci_hcd and address 3 Nov 28 17:17:58 dukla kernel: midi: probe of 3-2:1.0 failed with error -5 Nov 28 17:17:58 dukla kernel: midi: probe of 3-2:1.1 failed with error -5 Nov 28 17:17:58 dukla kernel: usbmidi: found [ Roland PC-300 ] (0x0582:0x0008), attached: Nov 28 17:17:58 dukla kernel: usbmidi: /dev/midi00: in (ep:81 cid: 0 bufsiz:64) out (ep:01 cid: 0 bufsiz:64) Nov 28 17:17:58 dukla kernel: usbcore: registered new driver midi Nov 28 17:17:58 dukla kernel: usbcore: registered new driver snd-usb-audio Even better, it shows up as a device: me@dukla:~> cat /proc/asound/cards 0 [V8237 ]: VIA8237 - VIA 8237 VIA 8237 with ALC658D at 0xe000, irq 177 1 [PC300 ]: USB-Audio - PC-300 Roland PC-300 at usb-0000:00:10.2-2, full speed And yet I cannot see it as an input ALSA device: me@dukla:~> aconnect -i -o client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 62: 'Midi Through' [type=kernel] 0 'Midi Through Port-0' client 128: 'FLUID Synth (10018)' [type=user] 0 'Synth input port (10018:0)' I am running SuSE 10.0 x86_64 (kernel 2.6.13-15) which has ALSA 1.0.9-23.

[linux-audio-user] fst-1.7 -- build ardour with fst support.

Hi there,I'm using fst.1.7 for launch the vst's with very succes,thanks to everyone who did this posible,it works really greate. At the readme file included in the tarball I read this: / 5) build ardour with fst support. copy the SC* files from the ardour directory into your ardour build path. and the build ardour like: scons VST=1 VSTPATH=/path/to/compiled/fst-1.7/ I tried to compile ardour in that way,copied the fst-1.7/ardour/SConstruct to the build directory,and run scons with this options: /supertux@sid:~/proceso/ardour/ardour-0.99$ scons BUILD_SSE_OPTIMIZATIONS=1 USE_SSE_EVERYWHERE=0 VST=1 VSTPATH=/home/supertux/vst/fst-1.7/ PREFIX=/usr KSI=no DEBUG=yes/ But get some error messages:/ scons: Reading SConscript files ...
