[linux-audio-user] MIDI - hapless Newbie Q -

by tim＠glastonburymusic

Please forgive me if this is somewhat OT. The tone of this group makes me wonder if I signed up for LAD by mistake. I'm having trouble with what should be a trivial soundcard config. Tech Spec: Debian-3.0/Linux-2.2.20 running on a P133 with 48mB RAM Soundcard: Bluepoint/OPTi82C930 with MAD16 Driver Problem: communicating with external MIDI device (Roland D10) [No ALSA] using OSS basic internal functionality for samples & MIDI is OK Basically every time I try to load the mpu401 driver I get told "Device or Resource busy". I've tried using modprobe, modconf and sndconfig, same thing every time. CDrom audio is also disabled, and I have errors on loading unix socket drivers (which I don't entirely understand). I've tried every available I/O & irq combination that doesn't cause conflicts. It is entirely possible that I'm just using the wrong syntax of course:~) lsmod lists pcmcia_core, unix, lockd, sunrpc, af_packet, mad16, ad1848, uart401, sound, soundlow, soundcore & joystick modules. I'm not sure if there's anything obviously missing or conflicting. Any pointers would be gratefully appreciated. I guess you'll understand when I say that a functioning soundcard is as important as video. Music will hopefully be one of the prime uses of my setup & I'm very interested in stuff like Python OSS, tse3 & stk4 & others which run happily on my box already. Csound looks interesting too, but I may need to improve my hardware before I can properly use it. Right now, I will just be happy if I can simply demo my new song. thanks in advance tim hall forgive me if I spam :~]

[linux-audio-user] BPM from MP3's

by Angel Gabriel

Is there an automatic utility, that can extract the BPM of an MP3 file, and add it to the info tags with the file? A bit similar to what the windows PC DJ Blue and Red can do??

[linux-audio-user] ardour/boosthardware.com/quicktoots...

by Frank Barknecht

Hallo, I built and installed ardour (again after a long long time) and now I don't know what to do with it... There was an ardour quicktoot, but boosthardware.com cannot be reached from here. Is it dead currently? Did anyone mirror the ardour toots? And I cannot get ardour to read its pixmaps from /usr/share/arour/pixmaps, unless I change into that directory. Isn't this set up in $ARDOURRC if I "export ARDOURRC=/etc/ardour/ardour.rc"? ardour.rc contains the pixmap-path set to /usr/share/arour/pixmaps. (BTW, I'm using and testing the Demudi ardour-snapshot-build-system so far worked like a charm and makes compiling ardour a two-commands-issue) ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] ameter alsa plugin : new version 0.2

by Laurent Georget

Hi! Ameter is an alsa scope plugin that provides a peak meter for a lot of Linux sound apps . (It is derived from Meterbridge which is better, but some programs, not having Jack support, cannot use meterbridge ) New version 0.2 : - Decay similar to a real peak meter - Better precision It is there: http://perso.club-internet.fr/lgeorget/ameter.html Thanks for reporting compilation (or others) problems.

[linux-audio-user] is this a bug?

by jordan muscott

As discussed in the thread earlier today ( using jack-rack as real time effects processor ), i am, er, using jack-rack as real time effects processor. Anyway, I have hit upon some behaviour that doesn't seem right to me. I am putting some pretty heavy artillery ( basically some drums and a bassline ) through jack-rack and the compressor that shows up as "SC1" ( is this one of Steve's? I can't remeber ). Everything is fine until I drop most of the input out, and then the compression just stops working until I reload the plugin. Clicking 'enable' on and off doesn't work. Anyone know what is going on here? Thanks, J.

[linux-audio-user] multiple sound cards

by Michal Seta

Hi all I'm planning to install a second cheapo audio card from an old machine (an opti92C924 if that matters) as an additional card in my system (now I have an ens1371, if that matters). I've seen in the archives that in September 2002 Patrick Shirkey has done a possibly successful sync and was going to report if he could stay in sync for a long time. I'd be interested to know what are the pitfalls of such undertaking before I start messing around. I need more inputs mostly to do real-time manipulations on input wihin PD so am I wrong in thinking that sync does not matter much in this situation? However, having them synced, somewhat, would be nice for some multitrack recording... Any thoughts? Any and all help will be appreciated. ./MiS -- Michal Seta CreaZone http://www.creazone.com No One Receiving http://www.noonereceiving.32k.org NOR - "The Release of the Wandering-Eyed Girl" now shipping! http://www.grainofsound.com

[linux-audio-user] using jack-rack as real time effects processor.

by jordan muscott

Greets all, I've got a nasty feeling I'm doing something stupid here, but i'm fed up of doing it on my own. sound blaster pci 128 ( ens1371 ) alsa0.9rc1 jack 0.44.0 I want to use jack-rack as a real time effects processor. The first thing i'm not entirely comfortable about is that whatever audio I send to the IN on my soundcard seems to get sent straight to the OUT ( i can record stuff ok ). Then i'm starting jack: [root@larry jordan]# jackd -R -d alsa -d hw:0 and the starting jack-rack ( as root, of course ). I've tried using the -o -i options here too. I get the following from jack_lsp: [root@larry jordan]# jack_lsp alsa_pcm:capture_1 alsa_pcm:capture_2 alsa_pcm:playback_1 alsa_pcm:playback_2 I've tried making what seemed like the sensible connections here with jack_connect, but the sound i'm sending in either just gets echoed to the output ( as per normal ), or I get hideous feedback. Somebody, please help. Thanks, Jordan.

[linux-audio-user] MDK Survey Results

by Austin Acton

First, thank you all very much for your answers. I can't believe the response... a lot of great ideas in less than 24 hours. If anyone else has ideas, please let me know, as the project is far from over. The developers' mailing list at Mandrake is buzzing with audio talk now. :-) Here are the major complaints about Mandrake 9.0 in general, with comments. Where applicable, I will forward the suggestions or problems to the appropriate developers at Mandrake. 1. Supermount problems in 9.0 This is well known. This month a few people have been patching up supermount for 9.1. As for 9.0, most people find the problems tolerable, but you can easily disable supermount on afflicted drives by editing 'supermount' out of your /etc/mtab and /etc/fstab files. 2. Desire for unpatched kernel Mandrake has always included an unpatched version of the kernel. It is called kernel-linus rather than kernel, and is not installed by default. You can install it with # urpmi kernel-linus 3. Problems with alsa sound quality on certain devices If these are alsa-specific problems (occur on other distros), please report them to alsa-project.org. If they are Mandrake specific, it would be nice if you could test the 9.1beta2 release to see if we have fixed it yet. If not, please report to http://qa.mandrakesoft.com. 4. Drakx (our installer) too simplistic With most new distros tending toward MORE simplistic installers, I have a hard time understanding this. Try expert mode first. If that's still too simple for you, you're welcome to make suggestions at mailto:cooker@mandrakesoft.com our developers' mailing list. We have added a rudimentary sound card and sound system (alsa/oss) configurator in the Mandrake Control Panel, so you can change sound system and card quite easily at any time. 5a. Drakx doesn't detect/configure USB audio Pixel, the mastermind behind our installer was very surprised by this. He says if you send him your /proc/bus/usb/devices list, he will fix the problem. The exception is the Extigy. Currently it's not detected, and they're not sure if we can include the drivers for it. 6. Drakx installs too much by default I assume this is to help new users get a semi-complete distro in one step. As you mentioned, the alternative is to select no "categories" of packages, and select packages individually. We offer both methods. 7. No low latency patch Currently we have a mini-low latency patch in our main kernel. I 'think' we are waiting for the rest to be officially incorporated into the main kernel, but I'm not sure. I'll ask. A fully patched low-latency kernel has been available on the Mandrake Club website for 8.2 and 9.0 for some time now though. Not sure if it will be default in 9.1 or not. I hope so. 8. Libraries and header files are in separate RPMs and must be installed separately We do this because the average user doesn't need header files and they take up extra space. It is not true that they must be installed separately though. If you urpmi the -devel package, the library package will be installed automatically, but not vice versa. 9. Can't run jack unless root I don't know much about this, or whether it's true or not in 9.1. I've asked some people to look into it. Could someone tell me what commands they would like to execute but can't? Now for requested applications. To my surprise, most of these we do not include. I will do my best to get most of them included in 9.1. Some others we already include, or can't include. I'll comment below. Requested that we include already: snd mplayer Requested that we can't include: cinelerra (includes mp3 encoder) lame (ditto) both may be available at plf.zarb.org, a site run by outlaws :-) realplay (proprietary, available at www.mandrakeclub.com) Requested that we don't plan to include: broadcast 2000 (obsolete, hard to maintian) Requested that I know Tobbe is working on currently: ardour qjackconnect csound cecelia rtsynth swami muse pd ceres vkeyb all are available for Mandrake 9.0 at: http://rpm.nyvalls.se/sound9.0.html but are completely unsupported They will be in 9.1 for sure. Requested that I will personally look into: kaconnect amsynth spiral* (won't compile with gcc 3.2.1, will need to ask author to fix) freqtweak jmax seq24 Finally for favorite apps. I wanted to know what apps we should focus on, as well as estimate how well we are doing at including popular apps. Favorite apps we include: 56% of votes Favorite apps we don't include (yet): 38% of votes Favorite apps we can't/won't include: 6% of votes So it looks like we're not doing too bad! Looks like 9.1 could include 94% of your favorite apps. I really want to thank you all again for your help. Mandrake 9.1 should be released in April. Until then feel free to ask questions, pose suggestions, and submit bug reports. I will be on this list indefinitely I hope, as I'm a heavy Audacity user. :-) Austin -- Austin Acton Hon.B.Sc.
