Hello, I'm experiencing the fst lockup problem many have complained about on this list. Has anyone found out the cause yet? I'm using Wine 0.0.20040615-1 (from debian packages). Sampo

[linux-audio-user] Sequencer + Sampler

by Iván Almada

hi, ive been making music for 5 yrs with the computer, ive been using virtual sequencer + sampler configurations (cubase + halion) i just love making music this way (i dont use synths a lot, when i use them i render them to .wav and load it in a sampler) , i bought a creative labs audigy card for using the software sampler in realtime using the asio driver with my midi keyboard (yamaha DSR-500, very old but with midi!) and a dual head graphics card (ati radeon 7000)... ive been using it in windows with dual screens and just love the way dual screen works in a virtual studio... so, what i want to do is totally dump windows and start making music in linux i totally love this os , so i installed fedora core 2 with the all the planet ccrma tweaks and apps... i think i have a decent setup now, alsa, jack bla bla bla , i also have a decent computer (i guess) athlon xp 1700+ with 640 mb ram (or something like that) ... so, i have several questions: 1) Which software combination do you recommend for using a sequencer and a sampler? ive been using rosegarden, and i think its excellent but i havent found a way to hook up a virtual sampler, and i really need one!!! (have my own custom wav sample library ive been making all these years) is there any dssi sampler or something like that??? or maybe should i mess with the muse softsynth api ? or it would be better to use an external soft sampler like specimen??? any one knows other programs? or should i use a tracker and render to wav and load it in rosegarden or perhaps ardour??? or should i use soundfonts (ive never tried) and send midi data to the audigy wavetable? (thats the last option for me i guess... ive never really liked sf though ive never tried them really... i just like to make it all in a soft sampler) but if its needed then ill use this as last resort... or maybe should i buy an external harware sampler ??? any people with the same problem??? the second question: 2) how can i make 8th note shuffle in rosegarden sequencer?? are there anyways to create offbeat patterns??? this function is so important in my music. the third and last question: 3) any one knows how to setup the dual head monitor configuration? ive been trying to setup but failed... i have both monitors showing the same screen... what i really want is the Big Desktop extended in both monitors so i can use a sequencer in one and another program in the other... i think this is called xinerama in linux... i just cant configure it... thanks in advance (for the patience reading this mail) but i really want to setup my studio in linux... i only use windows for audio apps but i have to boot another hd and i also want to fully dump win32... i want to make music with open source tools... i know may be everthing is not as developed as in the win world but i am willing to accept drawbacks like having to configure everything by hand (a typical musician just want to use the tools and not worry about how the configuration) and trying to optimize your work (typically i just load as many vst synths as i need in my song i usually dont worry about cpu load and rendering everything to .wav ) im very excited about this excellent apps growing up and getting more stable like rosegarden and ardour... and being able to compose music with the opensource philosophy... ivan. _________________________________________________________ Do You Yahoo!?

Re: [linux-audio-user] M-Audio Delta 1010LT .asoundrc?

by jmacdermott＠ns2.i-mecca.net

Thanks, Jan. I will give that a try. I just noticed that Mandrake 10 (another partition on the same machine) shows all of the channels, so it automatically must have configured itself (neat!). I will try the same with Slackware, which is the one I am using for audio work. Thanks for your help!

The mixer (the one that comes with Gnome) has faders, and they do affect the sound levels. Is there any way I can test to see if an application is accessing /dev/dsp properly? Thanks... Jay

[linux-audio-user] SLACK 10.0, ALSA and VIA8233a...no sound

by marekjs

Hi. I use the motherboard SOLTEK SL-75DRV5, with VIA8233a. I haven't problems with OSS drivers (via82cxxx_audio).It works perfectly :).But...ALSA, hmmm, strange: completly nothing, silence. Anyway it's a short history of my battle with ALSA: - lsmod shows all modules - alsamixer is unmuted and 100% for all - IRQ 10, only for VIA8233a, no conflicts - a silence on kernels 2.4.x or 2.6.7 - modprobe.conf with standard settings from alsaconf (via82xx on slot-0) for kernel 2.6.7 - modules.conf with standard rules from the web, for kernels 2.4.x (I remember about ./snddevices...) - .asoundrc with hw:0,0 doesn't work (from ALSA web) - hotplug is running - silence on XMMS from ALSA (from OSS-no problems) - I prepared missing devices into make_extra_nodes.sh (similar devices like snddevices for kernels 2.4.x) - when I close KDE, I have: "ALSA lib pcm_hw:549(snd_pcm_hw_start) SNDRV_PCM_IOCTL_START failed: Broken pipe" That's all.

[linux-audio-user] M-Audio Delta 1010LT .asoundrc?

by jmacdermott＠ns2.i-mecca.net

I have been having great luck with Slackware 9.1 and Luke's AudioSlack software. With my onboard sound chip (using SI7012 driver) I was recording with Adrour, getting zero xruns in Jack, even with Hydrogen running in the background providing drums! Wow, I was impressed. So I made the jump to a higher-end soundcard and installed the Delta 1010TL. Now, it seems to be recognized by Alsa, because the Ice1712 driver is loaded. When I cat /proc/asound/cards I see it as 0 and the onboard sound chip as 1. There are also entries when I cat /proc/adound/devices. But now I am completely lost... I have been reading the documentation on the .asoundrc file, and have even tried to replace my existing file with something I pulled off teh Alsa site for another, similar card that used the same driver. Can anyone help me make sense of setting this up? Is there a standard setup that for all of this cards ins/outs? I feel like it's way over my head. Thanks for any help! I am a little discouraged today, but I am very pleased to finally be making some music in Linux! Jay

[linux-audio-user] Beatrix

by philicorda

Anyone who likes hammond has gotta give this a go. It's a virtual organ with a really big warm sound. No gui yet, but having loads of presets make up for that. Sorry if this is old news, I just discovered it on the 'sound and midi software for Linux' site'. http://www.dsv.su.se/~fk/beatrix_home.html

[linux-audio-user] Can you record with OSS & Esssolo1?

by jmacdermott＠ns2.i-mecca.net

Another, hopefully not too obscure, question... I have a Fedore Core 1 system that I'd like to record radio programs with. I found a great little program, RadioCap (http://www.scheinwelt.at/~norbertf/radiocap_homepage/), that will do just that. It listens to /dev/dsp for its input. FC1 uses OSS as default, and for the soundcard in this particular machine it was working fine using the ESSSOLO1 driver. When I plug the radio into my mic or line-in ports and unmute the channels, I can hear the radio through the PC's speakers. But no input level shows on RadioCap. I did a few tests with XMMS, etc., and it certainly seems to be using /dev/dsp for sound. Is this a sound card problem? If I can hear the input, shouldn't it be able to record it? Any suggestions would be appreciated. Thanks, Jay

Re: [linux-audio-user] MusE Race Condition

by davidrclark＠earthlink.net

Hi Robert (with note to Christian Henz), Thanks for your reply here, also, and for the suggestion. I also have the Radeon 9200. I just went out and got the latest fglrx driver --- just before seeing this message in fact. I was previously using the Radeon drv. Previously I was a little apprehensive and worried about using fglrx and had put it off (since January!) but decided that perhaps a change in the DRI module might be an improvement. So I was glad to see that you had also installed these drivers. fglrxinfo: display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: RADEON 9200SE DDR Generic OpenGL version string: 1.3 (X4.3.0-3.11.1) <<<<<--- new one MusE now will not lock memory under any circumstances I have tried, even with your suggestion of limiting the VideoRam. WARNING: Cannot lock memory:: Cannot allocate memory WARNING: Cannot lock memory:: Cannot allocate memory midi thread 1652 _NOT_ running SCHED_FIFO qjackctl still locks up the system, even with your suggestion of limited VideoRam. With ulimit -l 128000 or anything else qjackctl works just fine. MusE won't lock memory with either unlimited or 128000. So, I would conclude that IF MusE would be allowed to lock memory, it would lock my system up just as qjackctl does when ulimit -l is unlimited. I'm not sure how much I really want to pursue this. Linux isn't a real-time O/S, so trying to make it act like one is probably doomed --- at the very least, it's complicated. (Note to Christian: I've seen postings with troubles with 2.4 as well, so it's not just 2.6. The postings I saw were with respect to other programs, but still memory locking stuff.) Thanks again and best regards, Dave.
