Hi, I learnt that there is a bunch of good rt-kernels for Debian in Pengutronix repos. Thanks to youki on 64 Studio forum for the tip: "Add this to your sources.list: deb http://debian.pengutronix.de/debian/ sid main contrib non-free And install the package pengutronix-archive-keyring for the key." They should work at least in Lenny, Sid and AVLinux 3.0. And why not in Squeeze too. I use currently 2.6.31.6-rt19-1-amd64 in Lenny, rolls just fine. Greetings, Tapani

ALSA-driver package frustration/hate, on Debian Lenny

by Ken Restivo

I'm trying to build the alsa-source package on Debian Lenny. It hates me. I've built the kernel_image and kernel_headers, no problem. But as for alsa-source?

+1 for tapeutape!

by Josh Lawrence

last night I played with tapeutape for some time, and it's a really nice application. I took some drum samples from hydrogen's drumkits, loaded them up, and had a ball playing them via seq24. here are some good points to consider: 1. it works great as a drum sampler. throw a bunch of, say, hihat samples at it, and it will spread them across the velocity ranges so it will respond just like you would expect; 2. it's light, so if you don't want to call up hydrogen just for a drumkit, it works great for that. 3. don't stop at drum samples! once my drumkit was loaded, I loaded a few bass loops in there to trigger, and they worked just great, too. finally, one little glitch I noticed: when you go to save your file, you might notice that no matter what you type for a filename, the save box is greyed out (unavailable). just put ".tap" after your filename, and you can click save. anyway, thought I would throw some props to this nice app. http://www.tardigrade-inc.com/index.php/En/Tapeutape -- Josh Lawrence http://www.hardbop200.com

USB audio interface support?

by Ng Oon-Ee

Hi all, two quick questions (new to this list, let me know if I'm doing this wrong), 1) What's support like on Linux on the USB Audio Interfaces? Specific list below. I guess this is pretty much a 'does alsa support these devices', at the current moment? Obviously this is the primary requirement compared to 2). 2) I've got a Shure SM57 dynamic mic which needs amp-ing to get a useable signal for my laptop. Instead of just getting a pre-amp I was figuring I may as well get a USB audio interface, enabling me to finally use the MIDI output of my Korg as well as record a presumably good signal direct from my SM57. I've seen various complaints on the Fast Track Pro, for example, that the SM57 volume is just too low for quiet recording (ex. recording accoustic guitar), and its been confirmed as an issue by one of their engineers (http://forums.m-audio.com/showthread.php?t=14610). So the second question is, is this a general issue with the SM57 and budget USB audio interfaces, or would one of the list below be better? I'm looking at the following interfaces:- a) M-Audio Fast Track Pro b) Alesis IO|2 Audio/Midi Interface c) Tascam US-144 USB 2.0 Audio and Midi Interface d) Edirol UA-4FX USB Audio/MIDI Interface Please feel free to recommend alternatives with similar feature set (XLR input, 1/4" input, some sort of MIDI is a preferred bonus). Thank you all.

Can the GigEdit do this?

by Julien Claassen

Hi! I'm just waring with a gs3 setup. I got samples and .gig files seperately, now I'm supposed to import them. Here's the relevant excerpt from the guide: Right-click in the sample window and choose "Replace all samples in all folders". In the "Replace all samples" window, set the Root Directory to the folder containing the .wav-samples. Check the "Match samples by name to .wav/.dlx files anywhere under the root directory Click on the "Replace" button. After all samples are replaced, choose "Save" under the "File" menu. If GigEdit can do this, there's another question: Can I start a LinuxSampler engine on my system and allow someone to use it from the outside? IOr do I better compile/install everything necessary here and grant ssh access? Thanks and 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 ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

resampling flash and gstreamer to 24/192

by Bearcat M. Sandor

Yesterday i asked for assistance figuring out how to get mpd + pulse audio upsampling to 24/192. The results are *fantastic* Bass is deeper and tighter, decay is longer and vocals are clearer. I don't know why. It kinda makes sense and it doesn't. It might all be in my head. Anyhow, now that MPD and pulse are set to 192 they sound great. However, gstreamer apps drop out after a few seconds, and sometimes pause for a few then come back in for 5 seconds, then pause, come back in for 5 seconds (playing at the right speed however). Flash (adobe not gnash or swf) stutters or doesn't come in at all. Is this a buffering issue or because *they* are playing at the (now) wrong bit rate? Setting pulse back to default fixes that but i'd really like to have gstreamer and flash resample to 192 to synch with pulseaudio. Looking around i cant figure out a way to tell my system "every thing you play with gstreamer, resample it to 192 first", and there's *nothing* on doing it with adobe flash. Any ideas or pointers? Do i need to have them resample or so i need to increase buffers (somehow) If i can't do it that preferred way, isn't there a way i can set up pulse so i can switch the bitrate back and forth with a toggle? If this is too much hand-holding or not appropriate for this mailing list just tap my muzzle and point it in the right direction. Thanks -- Bearcat M.
