FIGGS 0.001 released (Symmetry and Music)

by Green Kobold

Hi Folks, FIGGS (Finite Groups in Granular Synthesis) is an app dedicated to musical exploration of symmetry concepts. I think that its better for constructing musical structures that for granular synthesis itself. Its all written in python, and its GPL in case someone is willing to help somehow. In this link one can find the program (FIGGS.zip), an article about it, some slides (maybe better than the article to get the idea), screenshots, a little video of the app running, and some music done with it: http://cortex.lems.brown.edu/~renato/sonic-art/nics/<http://cortex.lems.brown.edu/%7Erenato/sonic-art/nics/> For now it has a GUI, but it is still very research oriented, you might have to know (or learn) some group theory before doing something consciously. And its running over SAGE (Software for Algebra and Geometry Experimentation), with python packages installed on its own python interpreter. The code is as messy as i could do, for i am the only developer until now. So, if someone wants to do something with the code, write me and i will clean it. If someone knows Portuguese, it might be good to start here (under FIGGS title): http://www.estudiolivre.org/tiki-index.php?page=Usu%C3%A1rio_gk enjoy, cheers, gk or Renato

Software mixer for an USB-Audio - FastTrack Pro?

by Marcos Guglielmetti

Hi! We are testing an USB-Audio - FastTrack Pro using Musix GNU/Linux (Debian/ETCH compatible) on a Toshiba Notebook, Genuine Intel(R) CPU T2060 @ 1.60GHz (dual core) Linux Musix 2.6.21 #1 SMP PREEMPT Fri Apr 27 18:08:33 EEST 2007 i686 GNU/Linux amixer -i -c 0 does not output anything. Also, gamix, gnome-alsamixer, alsamixer, alsamixergui, kmix, etc: nothing. Jackd starts Ok (and with noxruns running at lower latencies) using hw:0, hw:0,1 (or so, I dont remember right now), It can play and record, but the mic input is too loud, and we can not control any souncards's input/outputs from the OS. Is there a software mixer for an USB-Audio - FastTrack Pro?

Convert data from old SMPTETrack Atari to standard MIDI foramt?

by Ken Restivo

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Somewhat off-topic, perhaps, sorry. But I have some data in the proprietary format of the old SMTPETrack program for Atari ST, but I long ago sold the Atari and the SMPTETrack software and its little game-port SMPTE dongle (which was the copy-protection for the software too). Just for curiosity's sake, I'd like to get a couple of those files converted to standard MIDI format, and try to listen to 'em using PC51 soundfont in fluidsynth, for instance, and all the other wonderful modern tools of linux goodness. Any ideas how to do that? Short of buying an old Atari ST and the SMPTETrack dongle on EBay? This is only a mild curiosity and probably not worth spending money (or even much more time than an hour or so). - -ken -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHAGm5e8HF+6xeOIcRAuyZAJ0Z6vp1ZSynUP20A0sCATKrcJKbIgCghVZd 8EXEFFf6Rv974GwKruyaZw8= =iGUz -----END PGP SIGNATURE-----

by Bearcat M. Sandor

Folks, Alright, a hard boot did it. I guess the card needs to be reset. Still, how can i adjust the master volume? The master volume meters do nothing but sit there and look dull. Bearcat M. Sandor

Output to 2 sound cards simultaneously

I've read this a couple of times over the years but it still does not make much sense (to me)... http://alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html As a baseline, say I started with this, where could I go from here to get an app (ie; Amarok) to play back out two soundcards at once ? # cat .asoundrc pcm.NVidia { type hw; card NVidia; } ctl.NVidia { type hw; card NVidia; } pcm.USX2Y { type hw; card USX2Y; } ctl.USX2Y { type hw; card USX2Y; } pcm.shared { type dshare ipc_key 321456 # any unique value ipc_key_add_uid true slave NVidia slave USX2Y bindings { 0 0 1 1 } } --markc

SCSI controller (aic7xxx) and xruns on 2.6 rt9 kernel

by Romain Bossart

Hi, I have many xruns when I read/write files on my SCSI disks. The suspected module is aic7xxx. I read a thread on LAU ('xrun madness') about this, but it dates back to 2004 and gives no solution. This problem does not occur with my other SATA drives. Could someone give me advices to troubleshoot this? Details: I have an Adaptec 39160 controller and 2 disks in a RAID1 (software) array. The module is aic7xxx. My filesystem is ext3. I use debian/unstable with a 2.6.22 RT kernel and RTirq. I tweaked my PCI latencies to 0 for the Adaptec PCI bus using setpci. Jackd being launched RT, I have no xruns with journalling operations or updatedb. But moderately intense operations on this array do cause many many xruns: for instance loading files into memory (launching firefox, or apt-get update, or copying files). Of course, recording music with Ardour causes many xruns too. Quite surprisingly (for me), I have no xruns when using my other SATA RAID5 (software) array, even very intensively. Thank you for your help! Romain

Audio to midi, finding notes from an mp3

by Simon Williams

Does anyone know of a program which will convert audio to midi? Maybe that's a little ambitious. What about something that will show which notes are being played or what key the audio is in? I have some mp3s which I want to play along to, but I have no idea what key they are in or what notes are being played. The tracks move too quickly for me to pick out the notes. If all else fails, I need some way of sanely repeating a short section of music so that I can try and find the notes myself. Any ideas? Thanks Simon
