[linux-audio-user] m-audio Trigger Finger: Plug'n'play :)

by Christoph Eckert

Hi, JFYI: just bought one, and it works out of the box using the snd_usb_audio module. If someone is interested in the device, I can recommend it. One wee small tear: You can send sysex to the device to restore previous settings, but there's no way to backup the device on linux because it doesn't offer the possibility to request its memory content via sysex nor does it offer the possibility to invoke a dump from its interface. The german m-audio support was very kind and helpful about this matter, and I asked them to include a backup functionality in other/future devices. Don't know if they will do it. Best regards ce

[linux-audio-user] chuck - what's the catch

by Atte André Jensen

Hi I'm an oldtime csounder, that never found time to figure out pd or supercollider. Recently I enjoyed ams and om. Now, yesterday I found out about chuck. Seems very interresting, nicely documented and I was able to build it and run examples in minutes. So what's the catch? Why do we hardly ever hear anything about chuck here? Anyone here uses it? How does it compare to the rest (esp textdriven) "synths"? Hope someone could enlighten me:-) -- peace, love & harmony Atte http://www.atte.dk

[linux-audio-user] [ANN] Sineshaper 0.4.0

by Lars Luthman

The Sineshaper is a monophonic DSSI synth. This is the first release. Source tarball, screenshot and Vorbis demo are available here: http://ll-plugins.sf.net. The knob graphics are created by Thorsten Wilms and Peter Shorthose. The Sineshaper synth has two sine oscillators and two waveshapers. The sound from the two oscillators is mixed and passed through the waveshapers, first through the first waveshaper and then the second. You can control the tuning of both oscillators as well as their relative loudness, and the total amount of shaping and the fraction of that amount that each shaper applies. Both waveshapers use a sine function for shaping the sound, but for the second shaper you can shift the sine function (with maximal shift it becomes a cosine function) to produce a different sound. You can also add vibrato and tremolo, and change the ADSR envelope that controls the amplitude and shape amount (as well as setting the envelope sensitivity for both the amplifier and the shapers). There is also a "Drive" control that adds distorsion, and a feedback delay with controllable delay time and feedback amount. All control parameters can be changed using MIDI. The Sineshaper synth comes with some presets that you can play or use as starting points for your own synth settings. You can not change these "factory presets", but you can create and save your own presets. They are written to the file .sineshaperpresets in your home directory. If you make any nice presets I would really like to hear them. -- Lars Luthman PGP key: http://www.d.kth.se/~d00-llu/pgp_key.php Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E

[linux-audio-user] Software for Sine Wave Generation

by Douglas Ward

What is an easy way to generate sets of precise sine waves? I like to generate (currently, slowly) separate sets of sine waves each consisting of a fundamental and 2 - 3 pseudo harmonics (really only justly-tuned perfect fifths, octaves, and a third--major or minor, depending upon the type of drone I want). The goal is to produce examples of justly-tuned chords that are easy to practice and teach with. And, sine waves are the easiest waveform for brass instruments to play along with. (This is very useful for orchestral brass instruction, and brass chamber ensemble exercises.) My current toolchain is clunky: XMMS --> ToneGen[erator] plug-in --> Hard Disk playback --> Audacity (to add an envelope to the front of each set). I would like to find a way to make this process more streamlined. I would love to be able to write scripts to do the dirty work. What program is suggested for replacing this toolchain? I think Csound can accomplish this. (Can this be accomplished with Audacity+Nyquist, too? Is there a plug-in that will play multiple frequencies at once?) Are there any favourite command line applications that can be used to produce multiple sine waves at once? Csound seems overly complex for this application, but I do not know of alternatives. Is there anything other than Csound? I just want to make sure I'm not overlooking a great specialized program before digging into Csound. Thanks a lot, Douglas Ward

[linux-audio-user] Spanish song made with Ardour 0.99-3

by Marcos Guglielmetti

http://www.pc-musica.com.ar/ogg/Ansiedad-master3--q1--Marcos-Guglielmetti-M… ¡Hola! Este es mi 1º proyecto medianamente complejo grabado en Ardour con Musix GNU+Linux. Es una canción en castellano. Fue grabado primero secuenciando con Rosegarden utilizando Zynaddsubfx para bajo, teclados, distorsiones... y al mismo tiempo utilizando Hydrogen para la percusión. Luego trasladé las bases a Ardour 0.99-3 y grabé las voces. Fueron un total de 9 pistas de audio, y algo así como 10 pistas MIDI. Tuve algunos problemas de desconexión con Ardour hasta que le "agarré la mano"... aún así, no sé si algunos problemas se deben a que no es una versión 1.0 o a que hay cosas que aún no entiendo. Sea como fuere pude grabar felizmente, encadenando más de 7 efectos por pista si era necesario: compuerta, ecualizador de 15 bandas, compresor, limitador, flanger, de-esser, reverb, tape delay, etc. El resultado provisorio lo pueden escuchar en: http://www.pc-musica.com.ar/ogg/Ansiedad-master3--q1--Marcos-Guglielmetti-M… -- Marcos Guglielmetti Coordinador del desarrollo de Musix GNU+Linux (www.musix.org.ar) fecha: vie oct 28 07:25:02 CEST 2005 ___________________________________________________________ 1GB gratis, Antivirus y Antispam Correo Yahoo!, el mejor correo web del mundo http://correo.yahoo.com.ar

[linux-audio-user] [ANN] Dead good music

by tim hall

Hi all, To celebrate Hallowe'en / Samhain I have uploaded three remastered tracks to AGNULA libre music - I fully confess that these pieces were not made with Linux or any other computer system, they were recorded on a 4-track cassette machine, but they were remastered using JAMin on DeMuDi. So, to celebrate our loved ones who have passed into the other realms I offer these three pieces: http://muzik.agnula.org/view.php?view=track&id=2482 http://muzik.agnula.org/view.php?view=track&id=2481 http://muzik.agnula.org/view.php?view=track&id=2483 Possibly _not_ for the faint hearted. ;] -- please enjoy freely! tim hall http://glastonburymusic.org.uk/tim

[linux-audio-user] music apps being removed with Sarge/Etch updates

by Nigel Henry

Hi. The latest updates on my Debian Sarge/Etch (on the testing repo) are wanting to remove. Cheesetracker (libsigc++ deps) , Wavemixer, and Seq24. Now I use, or more precisely, am trying to use Cheesetracker, so don't want to lose it. All the upgrades appear to be coming from. deb http://security.debian.org/ sarge/updates main I tried putting this Debian Sarge/Etch install onto the security testing repo, but it don't want to play. I still have two basic Sarge installs, also on the same security repo, but aptitude dist-upgrade is only doing minimal upgrades, and certainly not wanting to remove apps. The ouput of aptitude dist-upgrade is below, (also tried aptitude upgrade, as sometimes they differ) . Any comments would be welcome. Nigel. Reading task descriptions...

[linux-audio-user] Non-graphical synthesiser solution?

by S. Massy

Hi there, I am toying with the idea to re-start playing with digital synthesis once again (haven't done so in a while now). Judging by the number of synth packages in the Debian archive, there is more than a few out there; however, most of them (bristol, ams, etc.) seem to be GUI-controlled (and hence require an x-server), which is not very practical for me. I can think of a few ways to rig up a modular synth with, say, ecasound, jack, and aconnect, but I was wondering if there is any programme, package, or idea already out there to make this easier. I also started playing with SuperCollider today, but language-driven synthesis are, by necessity, more of a long-term endavour, and, right now, I'm looking for more of a modular synth solution, especially LADSPA-driven. Any idea? Thanks, S.M. -- smassy(a)sdf.lonestar.org

[linux-audio-user] Whatever happend to the alsa config file?

by Alex Polite

Last time I checked my distro (Debian) had a separate configuration file for alsa. Now this seems to be gone and alsacon just generates a file that specifies which kernel modules should be loaded. So under the present debian alsa more or less "just works", without the clueless user (me) doing anything. My problem is that I want to add a USB audio interface and there's no config file for me to edit. Rerunning alsaconf doesn't make a difference. alex -- Alex Polite http://flosspick.org - finding the right open source
