Anyone been successful at running Bristol on FC6 x86_64 ? I get is the following (complete console output available): # bristol -jack -mini [...] /usr/share/bristol/bin/startBristol: line 302: 22346 Erreur de segmentation $BRISTOL/bin/brighton $* -engine And although that par tof the program has bailed out, there's still in 'ps aux': /usr/share/bristol/bin/bristol -rate 48000 -count 102 And jack has bristol entries for both audio and MIDI. Hey, if I actually try this with a MIDI keyboard... Nope. No sound. Anyways, there's no GUI to change sound parameters. Anyone been successful at running Bristol on FC6 x86_64 ?

[LAU] Anyone interested in JACKifying Beatrix?

by Tim Howard

Hi, I was just thinking it would be really great if someone (with programming skills several notches higher than my own) could JACKify Beatrix. Now, I realize that Beatrix is not GPL'd software, so it doesn't have anywhere near the community interest that it COULD have... <ahem> But just for the sake of usability, if someone could post a patch (which could also be submitted to the Beatrix author), I think there would be quite a few delighted people, myself in particular! :-) Any thoughts? -TimH

[LAU] Thinkpad R60 for Audio Update - Firewire Conflicts with Audio

by Spencer Russell

Hey List, So my initial concerns that the HDA Intel audio card shares the IRQ with ohci1394 seem to have manifested themselves. Using the kernel option pci=noacpi initially put most of my devices on IRQ11, but then I was able to move them around using the BIOS. Unfortunately, whenever I change the IRQs around, HDA Intel, ohci1394, and uhci_hcd:usb2 all seem to move together, which to me indicates that there's some lower-level hardware connection between the three of them. This means that I get loads of xruns if I try to run jackd with a firewire hard drive plugged in, which is a pain because I bought this enclosure specifically so that I would have access to the hard drive that has all my session files on it. Can anyone think of any possible way that I can use the internal sound card with my firewire hard drive? Maybe some deeper way of manipulating the IRQs that I'm not aware of? I'm planning on getting a PCMCIA sound card at some point, but after dropping 1,400 on this laptop my extra funds are a little tight for a while. Thanks, spencer

[LAU] looking for help with madfuload and udev in Ubuntu

by Hector Centeno

Hi, I've been trying to have madfuload working properly under Ubuntu Feisty and for a M-Audio Transit USB interface. The firmware loader works fine using the same laptop with Fedora Core 6. In Ubuntu for some reason the file in /proc/usb is not being created before the script /etc/udev/rules.d/42-madfuload.rules is called which gives this error: Apr 11 22:26:17 hector-laptop NetworkManager: <debug info>^I[1176344777.429847] nm_hal_device_added (): New device added (hal udi is '/org/freedesktop/Hal/devices/usb_device_763_2806_noserial'). Apr 11 22:26:37 hector-laptop madfuload: cannot open /proc/bus/usb/001/008: No such file or directory Apr 11 22:26:37 hector-laptop NetworkManager: <debug info>^I[1176344797.483518] nm_hal_device_added (): New device added (hal udi is '/org/freedesktop/Hal/devices/usb_device_763_2806_noserial_if0'). Apr 11 22:26:37 hector-laptop NetworkManager: <debug info>^I[1176344797.501767] nm_hal_device_added (): New device added (hal udi is '/org/freedesktop/Hal/devices/usb_device_763_2806_noserial_usbraw'). This is the entry in the 42-madfuload.rules that calls madfuload: # Transit ACTION=="add", SUBSYSTEM=="usb", DEVPATH=="/*.0", ENV{PRODUCT}=="763/2806/*", RUN+="/usr/local/sbin/madfuload -l -3 -f /usr/local/share/usb/maudio/ma006100.bin" I tried inserting a pause in madfuload to see if it was just about timing but I found that the error was till showing up after the pause and then the /proc/bus/usb/001/ entry was created. So it seems that for some reason udev first calls the rules script and then it creates the file, but I'm not sure if this is the way it's supposed to be and it's something else going on. At least madfuload is getting the right device file name when it's called (since the not found error filename is the one that gets created afterwards), meaning that udev created the environment variable DEVICE with the proper file name but the file doesn't exist yet, or something like that. After the failure and without unplugging the Transit, doing a "/etc/init.d/udev restart" loads the firmware and makes it work fine. I would be nice to fix this issue since beside myself I've seen other people in the Ubuntu forums complaining about the same problem since the previous version of Ubuntu (Edgy) without getting any solution (I even found complains about the same issue but with other USB devices, so it seems to be related to how udev works in Ubuntu). Is there anyone around who understands the inner works of udev who could point me to what to look for in trying to solve this issue? I can provide whatever extra information is needed. Thanks!

[LAU] my CD-R sounds weak and bland. What to do?

by millward

I wrote and recorded a nice little 7 tracks worth of sterio audio using Audacity set to CD quality. It all sounded great as a project file, and the burning of the CD showed no errors, but when I play it on the sterio it sounds so weak and bland compared to store-bought music CDs. What can I do to get some life into it? I know next to nothing about the production side of audio, so any comments, web sites where I can get information, or information of any kind would be appreciated. I have a major restriction with my recording. It's almost all done directly into the computer without microphones because I have to keep noise levels low around here. Bass sounds just fine this way, and even the electric guitar through a Korg box, but forget about loud guitar amps or PAs or anything like that. I do the vocals and harp on those rare times when no ones around. But the end result, the Audacity project file, and the .WAV file I export from it, sounds just fine. Its the burned CD-R on the sterio that sounds bland compared with regular music CDs. Something is missing.

[LAU] cards with built in mic pres?

by Loki Davison

Does anyone have a recommendation for a alsa supported card with decent mic pre's built in? Is an echo gina the only viable option? I've heard the 1010lt has pretty terrible mic pre's. There seem to be a few very cheap and nice looking aardvark cards on ebay with mic pre's. Can't seem to find anyhting positive about alsa support and the company is bust so guess it's not a priority. Any other options i should look at? This just seems the cheapest/best way. Anyone with the Mona/Gina/Layla 3g tell me about how the pre's sound? I have a griffin imic now so i think getting outboard pre's and a decent mic probably isn't the best option... unless i do something about the card. Thanks Loki

[LAU] jackd & debian problems

by Josh Lawrence

hello list, first off, I'm running debian etch, and installing everything via packages (sans the kernel). last night I decided I wanted to try out the sequencer dino, which requires a later version of jack than my repos offer. I uninstalled jack (which uninstalled other jack applications), and compiled the newest version of jack and qjackctl. this is where the problem started... now when I want to add a package from the repos, it wants to install the repos version of jack, and won't simply use the version I have compiled. conflicts abound, and the net effect is that all jack apps are not working at the moment. there must be some way in debian to say, "don't worry about the jackd dependency, I've already got that installed." or am I doomed to compile everything from source now that I've compiled jack from source? is it all or nothing? thanks, Josh -- Josh Lawrence http://www.hardbop200.com

We should investigate how is that practically feasible. First of all, who has to share something he would like others to complement? julien.

[LAU] Fwd: Re: My 'works in progress' made with linux

by julien bodd

Hi, > after typing this up i realised it may come across as being harsh in > parts. that definitely isn't my intention. Thank you so much for your suggestions ! They are really really really constructive. This really helps me a lot to start working on some of them. All of your suggestion are effective. When it comes to drums, I know the almost all sound crap, that's because a rythm for me could be a starting point (something just like a tempo) for creativity. Now, I indeed need to really make good drums of them. Again thank you for so many comments!! It must have spent a lot of time!

[LAU] My 'works in progress' made with linux

by julien bodd

Hi all, Finally, I managed to put some tracks online ! http://www.archive.org/details/TheTimelessClock Early stage for most of them, but I would like you guys to tell me which you like a little, a lot, or not at all. I'll probably continue to work on some of them. All music is made with linux only. Midi keyboard, mic (for voice and some djembe), freewheeling (for some of them rosegarden too), zynaddsubfx, dssi plugins, qsynth&soundfonts. Your comments are welcome ! Julien
