[linux-audio-user] [ANN] Snd-ls V0.9.7.12 and jack_capture V0.3.9

by Kjetil S. Matheussen

Snd-ls v0.9.7.7 =============== Snd-ls is a distribution of Bill Schottstaedt's sound editor SND. Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. Changes 0.9.7.7 -> 0.9.7.12: ---------------------------- -Fixed listener. -Removed various debug printing. -added --without-builtin-gtkrc configuration option. -Downgraded Snd from 8.4/26.9 back to 8.4/12.9 again. That upgrade was a mindless mistake. -Copied all files from my private snd three into snd-ls. Hopefully, this should make everything work again. -Added fix to make jackdmp work with standard installation of guile. -Don't quit snd-ls in case file can't be opened during startup. Bug reported by Dragan Noveski. -Disable FAM for now, because it fails for no reason during startup. Problem reported by Dragan Noveski. Download from http://www.notam02.no/arkiv/src/snd/ jack_capture v0.3.9 =================== jack_capture is a program for recording soundfiles with jack. Its default operation is to capture whatever sound is going out to your speakers into a file. This is the program I always wanted to have for jack, but no one made. So here it is. Changes 0.3.8 -> 0.3.9: ----------------------- *Changed the -rt option name to -d, to be compatible with jackrec. *Do not stop recording in case of disk errors. *Replaced deprecated libsndfile functions. *Added the --format/-f option. ("jack_capture -f flac", nice :-) ) (adding "-f w64" solves the 4GB limitation of wav files)

[linux-audio-user] PC Keyboard questions

by David Causse

Hi, I plan to make live music with a computer. My problem is I want to control the PC with the PC keyboard. Freewheeling permits to control with the PC keyboard. My keyboard have some annoying limitations for example I can press at the same time the letters 'azer', 'qsdf', 'uiop' but I am unable to press 'rtyu' at the same time, nothing is printed. I guess it is due to some limitations in its design. I'm afraid it's a hardware issue and I won't find an easy workaround. I'm also afraid that this special use of a keyboard is not the mind of manufacturers... So what solutions do I have? - keyboard macros : good idea but I will have to predefine everything and I consider it as a limitation for improvisation. - use only keys that works together, same here - find a keyboard that works well : good idea, how to find it, how can I explain to a pc resellers my needs... - use midi controllers : the best professional solution, but it's to much expensive... and I like the idea to make music with minimal requirements. So do you thing there is some good designed keyboard to perform this kind of stuff? Can some of you test their keyboard by opening a xterm and press at the same time 'rtyu' and see if all letters are printed and whenever they press more than one letter key all are printed in the term? Maybe gamers should be more aware of this kind of problem :) Thank you. David.

[linux-audio-user] Sad Angel (n)

by Folderol

Well, I just knew I would still be dissatisfied with this, so I've tried again. One day I'll get it right - but probably only for one day :( Actually I've changed the voices quite a bit this time, and sort of rediscovered harmonies that had got lost. Here is the (n)th version. (I don't know. I've lost count) http://www.musically.me.uk/music/Sad_Angel.ogg http://www.musically.me.uk/music/Sad_Angel.ogg -- Will J G

[linux-audio-user] Musical linuxsampler?

by Markus Herhoffer

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello! I am not a big friend of sampling as I am used to the sounds of real instruments. But I decided to give qsampler/linuxsampler (CVS version from Gentoo pro-audio overlay) a try. And as expected my virtual symphonic orchestra sounds disgusting. It seems to me that this is not a problem of the sampling quality. I use some mid-price samples in Gigasampler format. The real problem is the "statics" of the sound. Every tone sounds the same. This is extremely annoying on woodwinds and brasses. Now my question: Are there any dynamic MIDI parameters linuxsampler/libgig is able to react to? I've noticed that the engine interprets the pitch data. Are there any other parameters (like aftertouch, sustain, breath ctrl etc.) the engine responds to? Or are there other concepts for making the music more sound like real music?

[linux-audio-user] Ingo Molnar patches outdated?

by Ismael Valladolid Torres

Latest preempt patch available on Ingo Molnar's site is patch-2.6.18-rt7. However kernel up to 2.6.19-rc4 is available. Does this mean that preempt patches merged into the kernel in 2.6.19, or does this mean that I must stick to 2.6.18 if I want preemption?

[linux-audio-user] Here we go punk - Call for collaboration

by Thorsten Wilms

Hi! One of the leftovers of the time when I emulated punk-rock is this piece that never went beyond being basicaly just a MIDI-file. Now I would love to see life breathed into it and so this is a call to the instrumentalists, but especialy guitarists out there ... I hope someone likes it enough to record a track or 2 for me :) A rough-cut demo produced with bloody GM sounds and bad timing thanks to any combination of MusE, Cabling and my synthesizer keyboard: http://thorwil.affenbande.org/here_we_go_punk_demo.ogg It's not set in stone, we can talk about all kinds of changes and improvisation :) -- Thorsten Wilms

[linux-audio-user] Gentoo: Alsa/Snd-usb-audio not working anymore

by Markus Herhoffer

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello! I've already posted this topic to the official Gentoo forums, but nobody was able to help me. I've successfully run my Maya 44 USB together with the snd-usb-audio module for more than a year. But after the last update of ALSA some strange things are going on. "Alsaconf" doesn't find the USB soundcard although snd-usb-audio is loaded. mpg123 gives the following error: === Could not load default driver and no driver specified in config file. Exiting. jackd prints the following errors: Code: JACK compiled with System V SHM support. loading driver .. apparent rate = 48000 creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|hwmon|hwmeter|-|32bit control device hw:0 ALSA: Cannot open PCM device alsa_pcm for playback.

[linux-audio-user] pc suggestions

by Sciss

hello, i have been off the list for a while. i need a rather _urgent_ advice on the buying of a PC for combined Linux / WinXP audio. as a personal Mac user, i'm rather bad concerning the different CPUs, mother boards, firmwares etc. the budget is 3000 EUR, which must cover the whole computer including soundcard (= HDSP 9652 which is 500 EUR here). monitors we have already. the setup suggested to me is intel core 2 duo (which one? also i don't know if there are 64bit problems with windows or linux?), like 2.33 GHz or better, and ubuntu distribution, PCI architecture (to my knowledge RME hasn't released any PCIe versions of its cards), matrox graphicscard. the machine is standing in a separate room, so space / housing / noise is a rather low priority. the graphicscard must be able to feed two TFT monitors analogue (but digital-option would be cool), so the suggestion is matrox millenium p650 (costs 220 EUR approx. however 64 MB RAM doesn't sound extremely fancy nowadays??). it should have a couple of USB2 and a firewire connector. for people reading in germany, if you have any recommendation of companies selling those boxes (preferably "all in one") with linux compatibility in mind, i'm thankfull for receiving hints offlist. is there anything that certainly won't work? thanks, -sciss-

Personally, I don't quite understand why the two programs are even being compared. But a short version is that Timemachine is steve harris' emulation of a special minidisk player he has in a studio, while jack_capture is a general recording tool.

[linux-audio-user] jack: "unlock memory" and "soft mode"

by Atte André Jensen

Hi I'm wondering *exactly* "unlock memory" and "soft mode" (as they appear in qjackctl) do? Moreover: 1) Are they advised to be selected or not? 2) Under what circumstances would a check in either be beneficial and when not? -- peace, love & harmony Atte http://www.atte.dk | quintet: http://www.anagrammer.dk | compositions: http://www.atte.dk/compositions
