[linux-audio-user] Laptop/Ozone usb keyboard

by Atte André Jensen

Hi I'm thinking about getting a laptop mainly for live performance using softsynths (PD, Csound, something like that), but would also like to be able to use it for multitrack midi and audio recording. I guess the answer to "what laptop to buy for softsynths" is "the faster the better". Unfortunately I'm on a budget, but I'm very interrested in what kinda performance I can expect from various processors, clock speeds, amount of RAM etc (very vague, huh?). For instance I sac a Fujitsu/Simens AMILO running 2.0 GHz Celeron with 256MB of RAM. Would that be an option? Also I'm interrested in the Ozone USB keyboard, since it's compact and would give me audio/midi interface and some kind of controller. How is this thingy supported under linux? Is there anything I overlooked? Aspects to take into account? Other software to look at? Webpages to go to? Thanks in advance for any feedback! -- peace, love & harmony Atte

[linux-audio-user] [ANN] QAMix - MIDI controlled Mixer for ALSA

by Matthias Nagorni

Hello, the first version of my new QT based mixer for ALSA is available from: ftp://ftp.suse.com/pub/people/mana/qamix-0.0.1.tar.bz2 The mixer GUI can be configured with an XML description file. Default files are provided with the tarball. See the README for more. At this occasion I would like to also announce QARecord, a simple but multithreaded stereo recording tool for both ALSA and JACK. Version 0.0.9 fixes a bug in the level meters. ftp://ftp.suse.com/pub/people/mana/qarecord-0.0.9.tar.bz2 Have fun !

[linux-audio-user] [PATCH] envy24control widget limits, version 2

by Ross Vandegrift

Hello, The first version of my patch had a few glaring errors. This update fixes the following issues: * HW In level meters were broken * The last PCM Out meter was broken * S/PDIF channels can now be controlled with -s, --spdif * The Patchbay/Router and Analog Volume tabs now accurately reflect the number of requested channels in all cases. This update does not include the requested vertical layout changes. If I have the time, this is on my TODO list. The patch against 0.9.3 is included below, and available from http://poplar.seitz.com/~ross/envy24control/envy24control-control-limit-v2.… Testers would be greatly appreciated - especially those with cards other than the Delta44. -- Ross Vandegrift ross(a)willow.seitz.com A Pope has a Water Cannon.

[linux-audio-user] Audio Prototyping with Pure Data

by Levi Burton

>From the Inside Gamasutra newsletter: "Audio Prototyping with Pure Data" by Leonard Paul http://www.gamasutra.com/resource_guide/20030528/paul_01.shtml Interactive game audio requires combining content and code. Unfortunately, composers often have little control over how the code works and thus how the audio will sound in the final game. What's needed are tools that let the composer prototype the audio and show the programmer. One such tool is Pure Data, an open source program that is extensible, powerful, and, well, free. -- Levi Burton http://www.puresimplicity.net/~ldb/

[linux-audio-user] SLUGAMuSIG - Audio/ Music Group Second Meeting (fwd)

by Conrad Parker

June meeting of the Sydney Linux Audio/ Music Group http://www.slug.org.au/events/detail.html?id=71 ----- Forwarded message from Denis Crowdy <dcrowdy(a)pip.hmn.mq.edu.au> ----- Second Meeting of SLUGAMuSIG - Linux Audio/ Music Special Interest Group When: Saturday, June 14; 10am onwards Where: Macquarie University, Department of Contemporary Music Studies, building W6A, room 607 All interested in music/ audio and Linux are invited for the second gathering of the group. A more detailed list of proposed discussions will follow shortly, but the general plan is a demonstration/ discussion in the morning, followed by an open session of jamming/ coding/ talking in the afternoon. All levels of interest are welcomed. A relevant map of Macquarie is at http://www.ccms.mq.edu.au/crowdy/macmap.html. The best way to get to the Music Department (on the 6th floor of building W6A) is from the Balaclava Rd entrance (opposite Woolies from Epping Rd). The closest parking is "W4", and costs $6.00 for the whole day. For people arriving at various times through the day, the front door might be locked, but we'll keep an eye out, or call me on 0408 478 802.

[linux-audio-user] jc-a script for jack

by Jonathan Kraut

jc A python script for controlling jack connections http://home.earthlink.net/~krautj/ jc is an interactive command-line script that enables you to connect and disconnect jack ports with a few short keystrokes. It requires the pyjack module by Andrew W. Schmeder and was built with python-2.2. You may also choose to sever all ports from a given port or disconnect single ports. There is a help screen. It's the first thing I've ever written, let alone ever written in python, and comments and improvements are welcome. Good luck! And thanks to everyone developing audio software for linux! -- Jonathan Kraut Current email: krautj(a)earthlink.net (changes from time to time) or Permanent email: jak76(a)columbia.edu
