After the recent glut of very good stuff coming through the lists, I feel less inclined to expose myself. But I will anyway. http://dis-dot-dat.net/content/music/calmer.ogg And swap the ogg for mp3 if you prefer it. Jamin is playing silly buggers, so it hasn't gone through my usual final compression to sort out levels, but I'm not going to play with it any more. I can't play guitar, so I've tried to make something that sounds like an electric guitar. It's actually a mangled sample from ZynAddSubFX, so it's probably better to call it an ecclectic guitar. Anyway, comments not just welcomed, but begged for, as usual. James -- "I'd crawl over an acre of 'Visual This++' and 'Integrated Development That' to get to gcc, Emacs, and gdb. Thank you."

[linux-audio-user] Problems appling realtime preempt patch to 2.6.12

by Iain Duncan

Hi folks, wondering if anyone can help me. I successfully patched 2.6.12 with the latest Ingo patch with the settings for Desktop-preempt, but when I try ( on a clean source tree patched again ) to compile with the full preempt option I'm getting: LD .tmp_vmlinux1 drivers/built-in.o(.text+0xabbad): In function `carm_init_one': : undefined reference to `there_is_no_init_MUTEX_LOCKED_for_RT_semaphores' make: *** [.tmp_vmlinux1] Error 1 Anyone had this? The patch I am using is: realtime-preempt-2.6.12-final-V0.7.51-27 The sources are vanilla 2.6.12 from kernel.org. Thanks Iain

Re: [linux-audio-user] [ANN] Specimen v0.5.0 and PHAT v0.3.0

by davidrclark＠earthlink.net

Pete, Thanks again for your work on Specimen. It continues to be one of the very few "Linux audio" programs that I actually find useful. Although many Windows audio programs have sampler capabilities, I have not found one that is as easy to set up and use for single sample to single note as Specimen. It is very unusual to find a Linux audio program that is significantly better than any Windows counterpart (both standalone and subcomponent) that is commonly available, but in my opinion you have created one. Best regards, Dave.

[linux-audio-user] [ANN] E-Radium V0.61b

by Kjetil Svalastog Matheussen

Download from http://www.notam02.no/arkiv/src/ E-Radium V0.61b --------------- Released 12.7.2005 INTRODUCTION ------------ E-radium is Radium and a special version of E-UAE. Radium is a midi music editor for the amiga and E-Uae is an amiga emulator. This version of E-Uae is a hacked version of 0.28cvs, which runs with realtime priority to get accurate timing and supports alsa-seq to access midi. It does not hog the cpu as much as e-uae does either so it can be used together with various sound synthesis software running simultaniously in linux. E-radium has been tested with both the 2.4 kernel and the 2.6 kernel and with a ~1GhZ machine and a ~2ghz machine. (A 2.4 kernel with a 100hz resolution timer will proably not work very nice though.) COMPILING --------- make RUNNING ------- 1. Run ./e-radium 2. Unpress the "Pause" button. 3. Select which resolution you want to run radium with. 4. Connect midi-ports with qjackctl, aconnect, qconnect or similar tools. CONFIGURING THE KEYBOARD ------------------------ If you are a non-us keyboard user, you might have to configure the keyboard by setting the approporitate type. e-uae currently supports fr, us, de, dk, se, it and es. Pick the one closest to what you use, and put it into the "kbd_lang"-field in the file ".uarc-radium". (The keyboard should rather have been mapped directly from the keys though....) QUICK RADIUM GUIDE ------------------ * Move the editor-window to front, press "Ctrl + 1". * Maximize the editor-window, press "Altgr + 1" * Maximize the tracks in the editor-window, press "Ctrl + m" * Move the playlist-window to front, press "Ctrl + 2". * Move the Midi-properties-window to front, press "Ctrl + 3". * Move the Help-window to front, press "Ctrl+4". (Use right mouse button to access menues) * Play song press Altgr+Space. * Play block, press Right windows + Space * Stop: Press space * Continue song: Press Right Shift + Space * Undo: Press Right Windows + U * Redo: Press Right Windows + Right Shift + U * Toggle midi-editing on/off, press Esc. * Move 10 lines up/down: Press Left shift + up/down * Move between tracks: Press AltGr + left/right * Add block: Press Ctrl + f * Move to next block: Press f * Move to prev block: press a * PANIC! Hold down left and right mouse buttons for 2-10 seconds. The player should then stop. + A lot more. Check out bin/keybindings.conf for the complete list. This file can also be editied. ABOUT MIDI ---------- E-radium creates 8 public alsa-midi seq ports. Currently, only the 2 first ones are enabled. To enable more, check out the file s/startup-sequence. On the linux-side (alsa-seq), the name of the ports are uae0, uae1, uae2 and so on. On the amiga-side (camd), the name of the ports are mmp.0, mmp.1, mmp.2 and so on. These are directly connected if enabled in s/startup-sequence. Radium is currently configured to read midi from the uae0 alsa midi port. LINUX VERSION OF RADIUM ----------------------- Radium runs quite okey on its own (v0.63), but its not quite there yet. Until its there, running it via uae is the only way to use it besides using a real amiga of course (altough that is much slower than emulating).

[linux-audio-user] DeMudi + security

by Kevin Sookocheff

Hello, Recently there has been news that Debian is lacking in security updates (http://linux.slashdot.org/linux/05/07/05/217225.shtml?tid=90). I've been pondering installing DeMudi for a while but want to know what people think of these security problems. I don't particularly like red-hat so keep that in mind. Does anyone use Mandrake for pro-audio. It's what I'm most familiar with but I don't want to have a mountain of configuration problems to get real-time performance. What about Ubuntu with the DeMudi packages? Is this relatively easy to setup? Thanks for any advice, Kevin

[linux-audio-user] NoteEdit - TSE3 library only works under root

by Brett McCoy

I'm trying to get NoteEdit (2.7.4, installed via Demudi) to work correctly under Debian Sid and I can't get the MIDI sequencer (via the TSE3 library) to work unless I start noteedit as root. This is just a (more or less) vanilla 2.4.22 kernel, no low-latency patches and not running jack or anything. tse3play also only works when run as root, so All other MIDI-based apps work correctly on the machine in question (Rosegarden, timidity, vkeybd), so I am pretty sure the problem is in the tse3 library. Any one run into this and know a workaround? -- Brett -- Programmer by Day, Guitarist by Night http://www.chapelperilous.net http://www.alhazred.com http://www.revelmoon.com

[linux-audio-user] Jackd outputs noise

by Pierre-Antoine Champin

Hi again linux audio users I kind of solved my problems with my Audiophile USB : now jack runs without any xruns, but playing anything (for example with "alsaplayer -o jack" or ardour) only outputs noise. Jack does not output any error/warning message, even whith the verbose option... any idea on what this may be ? thanks in advance... pA PS: if this can be of any hel to anyone trying to get jack working with an audiophile usb, I got it running with jackd -R alsa -P plughw:2 -C plughw:2,1 -p 256 -n 4 and turning the card off and on just before launching jack often helps (!)

[linux-audio-user] quattro usb (4i4o) on demudi121

by odiv .

hi linux-audio-users i'm trying to figure out how to make my maudio quattro usb use 4i/4o (runs only 2o) on this beautiful demudi 1.2.1. Unfortunatly im not a programmer, so as far as I could get, I made .asoundrc in /root as it's advised by Patrick Shirkley at www.alsa-project.com, And I think that compiling with qinit.c is quite important too, but I get qinit.c:1:28: alsa/asoundlib.h: No such file or directory. so I found asoundlib.h at http://www.alsa-project.org/alsa-doc/alsa-lib/asoundlib_8h-source.html (im not sure if its it) and im not sure either where to put it, to gcc -o qinit qinit.c -lasound -ldl -lm. This is where im standing. Could anyone give me a push. I would really appreciate it. thanx in advance daniel _________________________________________________________________ Undgå pop-ups med MSN Toolbar http://toolbar.msn.dk

Ladies, gents, and those in between, I got back into the hacking thing a couple days ago, and I'm pleased to announce new versions of both the Specimen sampler and the Phat Audio Toolkit. As always, the real tip can be had at www.gazuga.net. The stuff that I remember changing follows: Specimen -------- * Fixed CPU hogging * Added keyboard for setting MIDI parameters * Made patch list auto sorting * Made volume logarithmic PHAT ---- * Added a new widget, the PhatKeyboard Stay tuned for more! Peace out, -Pete
