Greetings, Thank you for all your great feedback on the last two betas! phasex-0.12.0-beta4 addresses all of the concerns brought up so far: Velocity: Many of you have noticed that velocity and aftertouch were completely unsupported. Now, velocity (with aftertouch) can be mapped to directly to oscillators and LFOs (by setting the source), used as a modulation source (adjust volume w/ AM or pitch w/ FM), or mapped to the filter in the filter-lfo section. GUI: Some of you mentioned that the colors were too dark with too little contrast, so now there are four GTK theme options: Dark (original purple background), Light (orange background), System (use the system GTK theme), and Custom (choose any gtkrc file for your theme). There have also been issues with getting phasex to fit on small screens (usually netbooks). The knob images have been trimmed down vertically (just blank pixels), and the padding between widgets has been almost completely cut out. The font can be selected in the preferences. Additionally, a true fullscreen mode has been added. It is now possible to fit phasex into an 800x600 desktop. Atom processors: Compiler optimization flags for the Intel Atom processors have been added to the build system. Run './configure --enable-arch=atom' to build for the Atom. To force 32- or 64-bit builds, use 'atom32' or 'atom64'. The rest is just small tweaks and bugfixes, such as fixing the segfault on quit issue, fixing all the compiler warnings, minor updates to the build system, new menu items, etc. As I don't have access to a netbook right now, please let me know how it works out with the Atom or other low-power CPU, or on any machine with a screen smaller than 1024x768. Of course, feedback from the rest of you is highly welcome, too ;-} Visit http://sysex.net/phasex/beta for source tarball, Fedora 11 RPMS, or Fedora 8 RPMS. Cheers, --ww

[LAU] HOWTO, AVLinux --> LVM?

by Jonathan E. Brickman

OK, I am officially intrigued :-) My focus is live; I do recording sometimes on laptops and then immediately copy it elsewhere, but my primary is a desktop box set up for transportability with two laptop hard drives, running ZynAddSubFX (Yoshimi from now on I think) and Qsynth as MIDI module with my keyboard. I have a third desktop hard drive installed also, not being used, as an aid to moving it all to RAID-1 which has seemed likely. But now I understand positively that LVM drive mirroring is an option. A few questions: 1. What are the advantages of LVM drive mirroring over RAID-1? I understand that one advantage is mdadm update issues; I have had a machine hosed this way too. Are there other advantages? 2. If I set up LVM drive mirroring, can I boot off either drive? 3. How do I set up LVM drive mirroring? 4. If I set up LVM drive mirroring and take a drive out, can I put that drive in another machine and expect it to boot? J.E.B.

[LAU] some live tracks - need some advice

by Dave Phillips

Greetings, I've posted some recordings from a performance of my band last Saturday night. The tracks are simple unprocessed and unmastered board recordings, made by the soundman for the gig. As such they're intended primarily as a record of the performance, but I'd like to use some of them for tracks on a CD to sell at gigs. Here's where I need the advice. As you can tell, the bass is too well-recorded (it had a direct line out). I'd like to be able to diminish its presence, but I think I need some advice on using EQ. Also, the originals had no processing, so I added a bit of CAPS Stereo Versatile Plate in ReZound. I'm curious to know what others here might do. Alas, there are no multichannel/multitrack versions, I have to work with the present stereo mix. You can hear the tracks here: http://linux-sound.org/audio/Woke_Up_This_Morning.ogg http://linux-sound.org/audio/Outside_Woman_Blues.ogg http://linux-sound.org/audio/I_Dont_Know_Your_Name.ogg MP3 versions are also available (s/ogg/mp3). I'll send them through JAMin later today, so any advice re: using JAMin would be especially helpful, but I'm interested in any & all responses. Btw, ReZound and the encoders were the only Linux audio software used for these tracks. Enjoy, critique, keep breathing. Best, dp

[LAU] Fons' auto-wah, live in action

by Ken Restivo

Here is Fons' great auto-wah plugin, being used live: http://www.pringlized.com/lahar/Song_3_flv.htm This was the first time I'd played with these guys, and so I wasn't entirely 100% sure of the arrangements or body language. So I screwed up a few times in there, oops. Also, the sound guy had the keyboards really hot in the mix. But, at least you can hear auto-wah happening, big time. Thanks, Fons! -ken

[LAU] Compiling yoshimi

by Jonathan E. Brickman

The 'ccmake' and 'cmake' steps appear to work fine, but when I do 'make', nothing happens at all. No errors, no compilations. Anyone know what I should try next? J.E.B.

[LAU] OSM Live

by Daniel Joshua Worth

The Open Source Musician Podcast community has started a new project to bring live free culture music to more listeners. The project is called "OSMLive" and it is basically a ice-cast server that can be scheduled for live performances. More information can be found at http://live.pipemanmusic.com. I would love to have more people schedule shows and help get the word out about them. If you want to schedule something send a mail to live(a)pipemanmusic.com Thanks.

[LAU] 64 bit systems

by Russell Hanaghan

I am almost convinced that I want to go Linux audio in my studio. I have a x64 3ghz dual core AMD based box that is my dedicated DAW. I am now deciding which distro to use that will give me stable performance with minimum effort. 64 Studio would seem like an obvious choice but because I would like to have VST's available, I seem to recall that is a possible issue? Beyond that, is there any other advantage(s) to using a x64 OS other than RAM access beyond 4gb? Is there any 32 bit OS performance degradation when installed on a x64 machine? Thanks, Russell
