Hi all, I'm thinking of building a new workstation, aiming for a (very) low price and decent performance. So far, I have acquired an Athlon64 3200 and 2Gb of RAM, and bought an NVidia NForce4 board and Antec power supply on eBay. I've spent just under £35 Sterling so far! I already have a couple of second-hand RME cards - a DIGI96/8 PAD and DIGI9636, which set me back £77 between them. So, I still need some media to boot from, and a graphics card - which must be PCI Express. I'm interested in using a CompactFlash-to-SATA adapter, and booting from a CF card. Does anyone know what the speed/reliability would be like? I imagine/hope that I'd be able to fit everything I need for a desktop and audio workstation onto 4GB or so? I can do without full-blown KDE or GNOME. I'll probably get a SATA RAID card, and a couple of drives later for file storage. Finally, the graphics card... What do you recommend? Is there anything to avoid? I'd much rather use open source drivers, but don't really have enough money to get a Matrox PCI-E card at the moment.

Price limit is < AUD$300 so i'm thinking of 2 behringer c-2's ($75!!) and stereo mic pre or a single SM Pro mic 1 condenser and pre. Are cheap condensers better than sm57/58 of the same price? Any recommendations? Loki

Linux stickers for laptop

by Ken Restivo

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have just gotten the news that I've got another live show to play on May 19th. If things go well, instead of borrowing the guitar player's Korg Triton (as I had to do for the last show), I will be playing my new Linux laptop. I want to plant a huge Tux sticker right in the center of the laptop cover. It's a barebones so it has no markings of its own; I get to put on my own. I've seen a logo of Tux wearing headphones too, which I'd like to find. Where might I purchase stickers of this type, suitable for laptop application? I want to stand up and be proud, and "represent", as the young folks say these days. - -ken -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFGMpYee8HF+6xeOIcRAr75AJ9YdXApEGBeIfFBR3kKucdW1zQF/ACg2Fl6 amv3MV71RU3cQzsUxeFrrjs= =rMWz -----END PGP SIGNATURE-----

Octaver or fuzztone effect

by robert lazarski

Hi all, I always liked Adrian Belew's song "Big Electric Cat" , and after hearing it again I'd like to see how close to that sound I can get. Doing some googling, Here is a quote from Guitar Player jan.'84: AB describing his onstage/studio equipment p.80- ...number 3 is my Foxx[Tone Machine]fuzztone. That's the sound in "Big Electric Cat" and "Paint the Road". "i always use it w/ the high octave sustain switch on. its my favorite effect, and not an easy one to find these days. i'm also daisy-chaining the Foxx-tone into an MXR 10-band graphic equalizer so that i can eq it." I'm actually a keyboard player with a korg triton classic and some relatively good guitar sounds ;-). I found some schematics for building a cheap fuzztone, but I've got plenty of excuses for trying to do this in software first ;-). Any ideas? Robert

Release announcement, Musix GNU+Linux 1.0 R1 Stable

by Marcos Guglielmetti

Thanks to the support of the Ututo Proyect, FSF, Ourproject, and to the usual collaborators, the Musix project has just released Musix GNU+Linux 1.0 R1 Stable, a new version of the 100% Free Software Multimedia Operating System for artists and general users. http://www.musix.org.ar/en/download.html After 2 years of hard work, the Musix project team is proud to announce the release of the first stable version of Musix. Musix is a 100% Free Multimedia Operating System derived from Knoppix and Debian/Stable, designed for artists as well as general users. Musix is specialized in audio and music production, but it also includes high quality software for graphics, video edition and many other tasks. This new release includes the Linux Kernel 2.6.21. The documentation was updated and many important applications were upgraded (among those: Ardour 2.0.0.2, Rosegarden 1.5.1 and the Musix's Control Panel). Some new programs were also installed (MScore, Nekobee and more). Many bugs were corrected and some new functionality added. The start-up system has been improved, (the "knoppix" boot argument and other options were added). The graphical artwork in the user interface and the functionality were improved: now it is really easy to change colour themes. KDE and GNOME applications look almost identical using the same colour palette and icon theme (crystalsvg). Now applications like The GIMP (GTK2) and Rosegarden (KDE) appear user-friendlier. Software featured in Musix 1.0 R1 includes: Ardour 0.99.3 & Ardour 2.0.0.2 (audio sequencer), Rosegarden 1.5.1 (audio/midi sequencer), Cinelerra (video edition), Bluefish (web design), The GIMP (image manipulation), Inkscape (vectorial graphic design), Blender3D (3D rendering and animation), Musix Control and more.

New LS-0.4.0 troubles under Debian etch

by Julien Claassen

Hi! I've got a rpoblem again, and I wonder how this is, for on my old system it worked. So I'm doing something wrong or the system is.But where. I compiled all the tarballs just fine (libgig-0.3.1, liblscp-0.5.1 and LinuxSampler itself. I start it, connect via telnet. And then do the following: CREATE AUDIO_OUTPUT_DEVICE JACK CREATE MIDI_INPUT_DEVICE ALSA ADD CHANNEL LOAD ENGINE GIG 0 SET CHANNEL AUDIO_OUTPUT_DEVICE 0 0 SET CHANNEL MIDI_INPUT_DEVICE 0 0 LOAD INSTRUMENT "historic.gig" 0 0 SET CHANNEL VOLUME 0 0.5 then I connect Jack and MIDI ports and everything is still fine, but immediately, when I touch the first key LS tells me: gig::Synthesizer: Invalid Synthesis Mode: 41 With another gig it told me the same with synth mode 40. What is going on? Where to look first?

Re: Mammut 0.59

by David Baron

1. To compile it, I had to fix a call in prefs.cpp. Note that this application uses Juce so build and install that first! 2. Tried it. The wonderfully musical startup screen triggered das_watchdog repeatedly. At least I was able to stop it thanks to this goodie. Was running on 2.6.21-rt7 kernel. Most syths and stuff will run after a fashion but I guess a 575mhz PIII is not up to Alley-Oop.

Announce: MAMMUT v. 0.59

NOTAM, the Norwegian production centre for work with sound, has released a new version (0.59) of NOTAMs Mammut software for Mac OSX, Windows and Linux. The new version of this unique frequency-based sound processing software brings performance improvements and major user interaction enhancements. For composers, sound designers, experimental musicians or producers looking for a new approach to sound creation and manipulation, Mammut delivers a unique way of working with sound in the frequency domain. Mammut will do a frequency analysis of your sound in one single gigantic FFT analysis (no windows). These spectral data, where the development in time is incorporated in mysterious ways, may then be transformed by different algorithms. An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. Different transforms can be applied to the spectrum, such as nonlinear stretching, spectrum shift, convolution, filtering and permutation. Mammut is a somewhat unpredictable program, and the user must get used to the idea of loosing control over the time axis. The sonic result is often surprising. However, Mammut is also ideal for standard operations like filtering, spectrum shift and convolution. The no-window approach gives ultimate sound quality. *Mammut version 0.59 features: * - A new approach to sound creation and manipulation in the frequency domain - Unique single gigantic FFT analysis method. - Stretch: Non-linear stretching of the frequency axis. - Wobble: Alternately stretch and contract the frequency axis - Multiply phase: Multiply all phases with the value you specify - Derivate amp: Replaces the amplitude spectrum with its derivative (slope). - Filter: Optimal bandstop filter. The ultimate in cut-off performance! - Invert: Splits the spectrum into regions with specified size, and turn backward. - Threshold: Removes all partials below a given amplitude threshold. - Spectrum Shift: Optimal spectrum shift, with no window artifacts. - Block Swap: Selects randomly positioned regions of the spectrum, and interchange. - Mirror: Reflects the whole spectrum around the frequency you specify. *For more information, visit their web site at: *http://www.notam02.no/notam02/prod-prg-mammut-e.html *Mammut is free, and can be downloaded from: *OSX: http://www.notam02.no/arkiv/macosx/ Windows: http://www.notam02.no/arkiv/windows/ Linux: http://www.notam02.no/arkiv/src/ Mammut: for composers, sound designers, experimental musicians or producers looking for a new approach to sound creation and manipulation in the frequency domain. -------------------- End of forwarded message --------------------
