[linux-audio-user] csound: Can it actually be compiled?

by S. Massy

Hi, I've been trying to compile csound on and off for the past two years and was never really successful: the closest I ever got to a working csound was a binary which would segfault every other run. So I gave it another try yesterday and again ran across some difficulties. Everything goes well enough until the linking stage at which point the whole things gives up and starts spewing messages such as this one: main.o(.text+0x341): In function `csoundMain': undefined reference to `POLL_EVENTS' Now, it appears that POLL_EVENTS is somehow related to graph generation; the problem is that I don't have any GUI installed on my system and therefore don't want to have anything to do with FLTK, TCLTK or X11, and it seems to be responsible for my problems. My question is: has anyone ever successfully built csound without the graph generation pieces? Any hint would be greatly appreciated. More info: sources: csound 4.23A from cs.bath.ac.uk system: Debian (unstable tree) compiler: gcc version 3.3.1 libc: glibc 2.3.1 Makefile: # DEFINES: I tried with and without -DRTAUDIO and it didn't do # much for me. DEFINES = -DSFIRCAM -DSYS5 -DPIPES -DMACROS -DIV_SCHED -DRTAUDIO -DLINUX # [...] CFLAGS = -Wall -O2 -falign-loops=4 -falign-jumps=4 -ffast-math -fomit-frame-pointer -finline-functions -funroll-loops -DWITHx87 $(RPM_OPT_FLAGS) $(DEFINES) # [...] LIBS = -lm -ldl Regards, S.

[linux-audio-user] aplay, plughw, alsamixer question

by Mark Knecht

Hi, Hi. I asked this question on Alsa-Dev yesterday, but 17 hours later got no answers. Excuse me to those that subscribe to both lists. This info is to help me do more debug work on a new HDSP 9652 driver version that I am helping to test. Should the volume levels I hear when using the command aplay -Dplughw:0 -r 44100 data/wave/seque~10.wav be controlled by alsamixer? The volumes for alsaplayer are being controlled by alsamixer, but this aplay command is not, at least right now on a new driver I'm using. Also, on a multichannel card, how do I direct the above aplay command to a specific channel? I am finding that with this new driver the audio is appearing on ALL channels on the card, even for a mono wave file. I think this is a bug, but I'm not sure. If there's an explanation fit for a simpleton like me about the difference between plughw and hw and when to use one vs. the other, please point me there so I can learn. I have read a bit on the Alsa site about plughw talking directly to the kernel, but beyond that I have not discovered any documentation yet. Thanks in advance. Cheers, Mark

[linux-audio-user] MIDI and Linux

by Daniel Klein

Hello all, I am completely certain that what I am about to ask has been asked a million times. But I am also rather tired of searching for answers for these things, and I've been looking around on and off for something like a year. This list is my best shot so far, so please excuse my ignorance and my laziness to keep looking all by myself. Next to this mail I have another question, but I decided to put that into its own mail to reduce confusion. Quick description of what I WANT to do: Compose music on my Linux system, playback MIDI files. What I HAVE done in the past: I've composed midis in windows for pretty much as long as I can remember. Starting on an AdLib card, I have never bought myself any other hardware than soundcards. I composed in MIDI only, using JazzWare (www.jazzware.com), which I would be able to get for Linux as well of course. What I HAVE in my computer right now is a Terratec DMXFire 1024. I assume I will not be able to use the samples on that card according to what I've read so far. I would *like* to keep composing in MIDI format, since I know that pretty well by now. I realize I will probably need a software synth or something like that and need to get myself patches from somewhere, and I have found a number of pages online, but have been totally unable to find some sort of VERY basic FAQ. So exactly what do I need.. is MIDI the way to go at all still or should I consider learning some other format (probably using some tracker like software.. a finnish friend of mine exclusively uses Impulse Tracker on his win box)? What Software Synth (if that is the name of the thing I will need) will I need, what can you recommend? It would of course be best for all if someone could just point me to a general FAQ and tell me to read the fabulous manual. Right now I'm also running ALSA 0.5.. there is some version of esound on my computer as well. Things are rather confused, but my other mail will be on that topic. Thank you in advance for your patience and more importantly, your answers. Daniel

[linux-audio-user] Re: [linux-audio-dev] wxWindows and Linux distros ?

My thanks to all who replied. It seems that it's a standard package with most of the mainstream distros, with the interesting exception of Red Hat. I haven't upgraded for quite a while, and wxWindows was not included with my ancient 7.2 install. Is it not in 8.0 or 9.0 either ? Best regards, == dp

RE: [linux-audio-user] Direct In

by eviltwin69＠cableone.net

I have recorded into my system (DSP 2000 C-Port) using an effects pedall and it sounds OK but if I'm serious about it I use my tube amp with a pair of condeser mics. You can't get the "tube sound" out of an effects pedal (unless it's a tube pedal and even then it's 12AX7 not EL84/6L6GC/5881 sound). The boost in the even harmonics caused by tubes just hasn't been emulated (to my ears anyway). Maybe someday.

I am something of an old-school rocker, not so much of a digital-techno-looper (although that stuff sounds fun too). I am curious to hear how you guitarists out there handle your sound. Do you all go direct in now? Or do some of you still mic your cabnet? I still have not gotten my system together because of extenuating circumstances, so I am still of the old school (namely, tape). When last I tried (about 10 years ago) there was no good (and affordable) way to go direct. Has that problem been solved in the modern Linux recording world? My friend recently purchased an "all-in-one" unit from Roland, a 24 track 24 bit digital recorder, that cost him about $2,500 I think (excluding cabling, mics etc). He says he goes direct -- and not only direct but totally clean. All effects, including distortion are added after the fact. He goes from his guitar into his recorder! This sure seems strange to me, although I can understand the logic there. Is this what you guys do? I would love to hear how you all handle this. :0) Thanks! Chris

[linux-audio-user] Sound on Sound Linux feature released

by Daniel James

It's now 6 months old, so here it is on the free part of the site: http://www.soundonsound.com/sos/Feb03/articles/linuxaudio.asp I think most of it is still valid information. Cheers Daniel

[linux-audio-user] csound and jack

by Atte André Jensen

Hi Is it possible to have csound output to jack? If not is there another way to route audio from csound to other apps, I'm esp. interrested in adding FX (mostly reverb/chorus)...?? -- peace, love & harmony Atte

Hi, I think this can be done through the alsa-jack plugin, but I didn't try yet. See: http://www.alsa-project.org/alsa-doc/doc-php/asoundrc.php3 -- Gerrit
