[linux-audio-user] bcf2000 presets

by John Anderson

I've been finding that I run out of sliders very quickly. There are two ways I can think of to solve the problem: 1) Create a second preset with channels 9-16. Which I've done, seems to work OK. Although I had to assign channel 2 to all the control change buttons for 9-16. 2) Use the "controllers only" (factory preset #1) and duplicate it up to 16 times with ascending channel numbers. And maybe tweak it a little to make sure the MMC buttons stay as MMC. I figure that certain apps that use the predefined midi control channel numbers (Rosegarden springs to mind) will prefer 1), whereas something like ardour which doesn't really care could work with 2). I don't know midi very well - is there something obvious that I've overlooked here? NRPNs? And in a setup like this where there are several presets to handle all the channels, what's a good way to handle the master channel - put it on the same position on every preset, or have a preset specifically for the master channel and monitoring and things like that? I've been working with the former, but I'm starting to lean towards the latter. Oh, and in the process of figuring all this out, I discovered that the text file written by the BCEdit java app is a ; delimited file containing the content of the sysex messages, excluding some header bytes. So I threw together 2 scripts, one (read.pl) that converts a file containing the sysex messages to a text format (same as the BCEdit format except with \n instead of ;) and another (write.pl) that takes a text format file produced by read.pl and writes the sysex binary format so that it can be piped directly to /dev/snd/midiCxDy. It works with a BCF2000 only right now, but a probably minor change will work with the BCR2000 as well. Thank to Pieter Palmers for bcx2000edit from which I borrowed that piece of information. Maybe someone will find these useful. And I've attached some samples. bye John

[linux-audio-user] running freebob enabled jackd with M-Audio FireWire Solo

by Devin Venable

I hope this isn't considered a cross-post, as I've already posted something similar to freebob-dev. But I think I may be beyond compile/install issues and on to basic user issues. I've managed to get freebob enabled jackd to build and run on my system, Ubunto Dapper 64bit version. I can run the daemon, but can't seem to get any jack clients to connect to it.

[linux-audio-user] Intel core-duo cpu and realtime patches

by joel silvestre

Hi all, I have a brand new T2400 core duo laptop and some problems... SMP realtime patched kernel hangs at kernel boot. I first try FC5/PlanetCCRMA with 2.6.16-1 out of box kernel. Both SMP rrt and rdt doesn't boot, non SMP versions works flawlessly. Then I try to compile 2.6.16 with rt26 patch and 2.6.17-rt7 on Ubuntu 6.06 with the same results. SMP hangs, UP works well. Non realtime patched SMP kernel works nice. Does anyone experience the same? Maybe (I hope!) I made a mistake somewhere? joel

[linux-audio-user] She's not a human being ("in your face-mix")

by Esa Linna

Just finishing my new tune: www.emvg.net/esa/shesnotahumanbeing.ogg and here's a copy from my blog from MySpace: My new song should have been a love song for my wife. Unfortunately she annoyed me for now forgotten reason (once again) and I wrote a song for our cat. Of course the lyrics in the chorus: "she's not a human being, she doesn't like Jeff Lynne, she's hairy all over the place" could be a perfect insult for my wife! This song has been recorded in many sessions, first ones many months ago in our bedroom. Drums were made with absolutely great software Hydrogen and I played the bass & few guitars through Behringer Tube Ultragain MIC200 -preamp/di and added some distortion & simulated cab "feel" with great CAPS plugins. Keyboards were played with Yamaha PSR-273 which was brought by Santa Claus for my kids. They are still wondering where the hell their keyboards are. The keyboard solo inspired heavily by Rick Wakeman was played through MIDI & astounding soft synth, ALSA Modular Synth. Right now I have fell in love with Bristol, another open source soft synth for Linux. Then some guitars were played with Behringer V-Tone Guitar GDI21 - a cheap but great sounding modelling preamp/DI. And then there were the vocals. I did millions of takes and it sounded everytime like shit. Finally decided to add "some" tube distortion from MIC200, and now I am mostly happy with it. I noticed too that mastering and mixing the whole damn thing should be done by professionals. I am on my holiday, sun in shining, sixpacks of cold beer is calling for my name and I sweat in my garage studio for trying to make my song sound like Green Day's Boulevard of Broken Dreams. Well, I didn't manage to do that. The mix you hear is in-your-face mix, with everything cranked up so that you can say bye bye for dynamics. But I am proud for the song, and want you to know that all of this wouldn't been possible without: Linux & Mandriva Linux 2006 Jack (jackit.sf.net) Ardour Alsa Modular Synth Hydrogen Audacity Jamin LADSPA plugins like TAP, CAPS and some more red wine Fosters Wojak Okocim Burgen Pils Grafen Walder Carlsberg bratwurst potato salad mushrooms (for eating, you fools!) and here's the lyrics (I know, they are bad - but purposely) She came to my life one august day and didn't like the songs I played She ran and runs away from me Far far away to maple tree She's not a human being She doesn't like Jeff Lynne She's hairy all over the place It's not a pretty thing to watch you eat those poor little birds and their raw meat -- ----------------------- http://www.emvg.net/esa http://www.emvg.net -----------------------

[linux-audio-user] Quiet case - P180B

by John Anderson

I just bought an Antec P180B case. Very nicely put together. Much quieter than before, although some fan noise still escapes from the top and back vents. I covered the top vent with the breakout box from the EWS88MT. That works quite well. It's big, and heavy. Not the kind of thing you want to be taking to a gig. I can still hear the hard drives when they're working, but just barely. The noisiest component in there was the chipset fan, which I've unplugged - motherboard temp is sitting at 34 C so it's a cool case as well. Now it's the CPU fan, the servers-in-progress in the room next door, the Alesis monitor amp which does the 50Hz Tango, and the ringing in my ears. Hmm. Maybe some good earplugs will fix that :-| My keyboard sounds more clackety than before as well. Which is good, I guess. I still think the fanless Zalman TNN cases are the ultimate (from the website Note : TNN500A's noise level is below 20dB and cannot be measured. The anechoic room used by ZALMAN has an ambient noise level of 20dB. ). But waaaay expensive. bye John

[linux-audio-user] website clean-up

by Folderol

I've done a bit more work on this and it all looks and works a bit better now I think. I know there are still issues with right clicking on some links. Bear with me, I'm working on it! There are also a couple of new tunes, and a few have both ogg and mp3 versions. As usual: http://www.folderol.ukfsn.org Hmmm, maybe I actually got it right this time :) -- Will J G

[linux-audio-user] which graphics card?

by R Parker

Hi, I need a display card that supports dual monitors out-of-the-box. This is for an audio box so 3D or whatever fancy features aren't needed. I'm running FC5 with Planet CCRMA and have no interest in changing distros. Experimentations in the xorg.conf file are unacceptable. Is that realistic? I'd like the thing to be OSS and licensed GPL so Lee Revel doesn't rip the jewels from my body when I ask for help configuring it. Of course the card you recommend is gonna work out of the box so Lee would never know if I'm sleeping with the devil... It took alot of time to configure the ATI Radeon 9500 to properly span dual monitors in FC3. I saved the xorg.conf file but of course it's back to the same old configuration nausea with FC5. And google searches return confusion and depressing news. I'll search a little more while waiting for some good advice. Thanks much, Ron I love Linux, I hate Linux...it never ends. I'm gonna poke out one of my eyes, fill the socket with salt and run around preaching the virtues of open source software to anyone I can get to listen to me. OK, I don't feel any better but will shutup. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

[linux-audio-user] [ANN] netjack-0.12 - Low Latency Network Audio Driver

by torbenh＠gmx.de

hi. netjack-0.12 is released. Netjack is a jack-driver which uses the network card. On the other end of the network there is a normal jack-client. So its possible, to share a single soundcard between several laptops. This release finally handles the packet disordering UDP does. Thus high channel counts can now be achieved. However a 24ch in/out link over 100Mbit gave me a major "net xrun" storm on vanilla 2.6.15 kernel. At a roundtrip latency of 2.9ms that is. It was reliable with 5.8ms. 16 channels gave me some "net xruns", which i could not hear though. i expect this performance to increase when using an rt-kernel with the network-irq set to rt-prio. So please report back. Additionally to the audio transport, netjack provides sample accurate transport syncronisation. The roundtrip latency is compensated for. get it while its hot at: http://sourceforge.net/project/showfiles.php?group_id=140191 there is no link on http://netjack.sf.net because the project shell servers are down. -- torben Hohn http://galan.sourceforge.net -- The graphical Audio language

[linux-audio-user] [ANN] ALSA MIDI Humanizer v0.0.1

by Cesare Marilungo

ALSA MIDI Humanizer is a tiny application that route MIDI events between two applications adding random timing and velocity offsets to NOTEON and NOTEOFF events, with a bare bones GUI to adjust the two ranges. More infos here: http://www.cesaremarilungo.com/blog/?post=17 Download: http://www.cesaremarilungo.com/download/ALSA-MIDI-Humanizer-0.0.1.tar.gz To build it just 'make'. For the developers reading this list: at the moment the code is just a quick hack. I didn't know anything about ALSA develpment, the GTK+ toolkit and linux threads until this morning when I've started studying some tutorials (used the midirouter.c code from the ALSA tutorial by Matthias Nagorni as a starting point). So, be kind. Comments and suggestions are highly appreciated. Thank you! c. -- www.cesaremarilungo.com
