[linux-audio-user] ANN: bristol 0.9.5-60

by Nick Copeland

Bristol has been updated with a user configurable ARP 2600 synth. It has the usual pre-patching as the original and, additionally, outputs can be redirected to arbitrary inputs. This was a few changes to bristol to adjust the engine buffer management for data that may feed back on itself, and additionally a few extra operators for electroswitches, reverb and ring-mod, etc. The envelope follower has not been tested at all and not all the patch possibilities either as there are honestly too many to go through - about 600 possibilities with just a single cable. The biggest changes were in the GUI. To support the user patches an extra layer was added for their representation, then this was converted into a transparency layer so the cables can be layered over the GUI to allow control of the parameters without them 'getting in the way', then the cables were coloured perhaps somewhat randomly - yellow patches carry signal left to right, red cables carry signal right to left when see from the user interface. Once that was done I put in a cheesy watermarked logo - you can clear it with the 'l' key or use the '-logo' option on the command line, but the effect was too good to miss out on. The transparency can be toggled with the 't' key to allow you to foreground and background the layer, and 'o'/'O' will adjust the depth of opacity. Load memory number 17, and play with the 'o' and 't' keys to get a feel for how the interface works. To patch, select an output (the jack sockets light up for outputs) and then select an input (these are just 'momentary'). This will direct the new engine routing algorithm for each voice and then paint in the GUI. To clear a patch just select either jack socket at the cable ends. The net output of the synth is reminiscent of the sounds from the BBC Radiophonic Workshop's greatest ever hit - the theme tune to 'Dr Who'. If you don't know what that is don't worry, it's perhaps a bit obscure. The original was composed on the elder brother of this synth - the ARP 2500 of which the BBC had a few, so the results came as a pleasant surprise. Graphics can be seen on the sourceforge homepage. Downloads as well of course. https://sourceforge.net/project/screenshots.php?group_id=157415 Regards, Nick. _________________________________________________________________ Express yourself instantly with MSN Messenger!

[linux-audio-user] Sound Works... Sometimes

by Steven Cabrera

Well after further review it looks like the .asoundrc file doesn¹t have much to do with it. Now it looks like the sound will work about every 4th or 5th time I boot. And also I looked at my /proc/asound/cards and it shows my delta 44 and the Unitor 8 but what about my built in apple sound? [steve@localhost ~]$ cat /proc/asound/cards 0 [M66 ]: ICE1712 - M Audio Delta 66 M Audio Delta 66 at 0x40, irq 54 1 [AMT8 ]: USB-Audio - AMT8 Emagic AMT8 at usb-0001:02:0b.2-1.3.4.2, full speed Can someone please help me with this?? Hi All, I have a strange problem with the sound in my system. I have Fedora Core 5 on a Power Mac 2.3gHz with a Delta 44 sound card and a Unitor 8 midi interface. I have spent much of the last month or so perusing the mailing lists trying to find the answer to my problem. OK here it is. The sound system works only after I boot once without a .asoundrc file and then boot again with one. There is a thread that discusses something about detection order. From what I can gather the Unitor 8 is being confused with a sound card. Another thing I think I understand is that there is no set order in which hardware is detected. What I don't understand is how to get the actual sound card detected before the Unitor. I read that in order to do this I should have something like "options snd-ice1712 index=0" in my /etc/modprobe.conf file. Here are the contents of that file: alias eth0 sungem alias scsi_hostadapter sata_svw alias snd-card-0 snd-ice1712 options snd-card-0 index=0 options snd-ice1712 index=0 remove snd-ice1712 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-ice1712 alias snd-card-1 snd-powermac options snd-card-1 index=1 options snd-powermac index=1 remove snd-powermac { /usr/sbin/alsactl store 1 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-powermac As you can see that line is in there. And being a Linux newbie I don't have much of a clue about what the rest of the file does. Here is the contents of my .asoundrc file: pcm.ice1712 { type hw card 0 } ctl.ice1712 { type hw card 0 } I would appreciate any and all help that comes my way. I'll even sing at your next wedding if you can help me get this working correctly :-) Thanks, Steve

[linux-audio-user] Just a little question

by Folderol

I'm still a bit confused about some aspects of setting up a machine for decent audio work. Does having RT kernel have any negative aspects when the computer is used for general office work? Would it be best to use a different computer for this (or different partition perhaps) and keep the audio M/C strictly for audio and nothing else? Am I right in thinking there are issues with some things (jack) working with root privileges that might have security implications? OK I know that's more than one question :) -- Will J G

I think the super-rolling R's are very cool. :-)

[linux-audio-user] 2.6.18-rt5

by yves＠jazzcomputer.org

Hi. I have achieved booting a 2.6.18-rt5 on a dual Opteron X2 system. As I've just had the idea of disabling HPET with this version of the patch, I can't say if it could work on an earlier version (it hanged on all versions theretofore). HPET has always been activated in the kernel I've compiled before. The config is there, it's only made for an AMD 8111 motherboard with Sil SATA chipset, but IDE is activated without any need of initrd : http://ypotin.nerim.net/myconfig Apparately, the rtc works better. This kind of messages (2.6.17.7) : Sep 25 10:43:42 fairlight kernel: softirq-tasklet/20[CPU#1]: BUG in __tasklet_action at kernel/softirq.c:493 Sep 25 10:43:42 fairlight kernel: [<c011e467>] __WARN_ON+0x67/0x90 (8) Sep 25 10:43:42 fairlight kernel: [<c0122d0b>] __tasklet_action+0xeb/0xf0 (48) Sep 25 10:43:42 fairlight kernel: [<c01234f6>] ksoftirqd+0xf6/0x1a0 (24) Sep 25 10:43:42 fairlight kernel: [<c0123400>] ksoftirqd+0x0/0x1a0 (48) Sep 25 10:43:42 fairlight kernel: [<c01318bb>] kthread+0xab/0xe0 (4) Sep 25 10:43:42 fairlight kernel: [<c0131810>] kthread+0x0/0xe0 (12) Sep 25 10:43:42 fairlight kernel: [<c0100e65>] kernel_thread_helper+0x5/0x10 (1 6) And also that (I had tons of that) : Sep 28 21:35:13 fairlight kernel: bug in rtc_read(): called in state S_IDLE! Sep 28 21:35:13 fairlight kernel: Read missed before next interrupt Sep 28 21:35:48 fairlight kernel: bug in rtc_read(): called in state S_IDLE! All this *seems* to have disappear, after three hours using the kernel. The rtc have stopped saying « eek » sometimes in the logs. Instead, I have tons of this kind of things : Sep 30 13:08:09 fairlight kernel: rtc: lost some interrupts at 1024Hz. Sep 30 13:08:31 fairlight last message repeated 1899 times Sep 30 13:09:01 fairlight kernel: 1024Hz. Sep 30 13:09:01 fairlight kernel: rtc: lost some interrupts at 1024Hz. Sep 30 13:09:16 fairlight last message repeated 1545 times [...] Sep 30 14:20:00 fairlight kernel: rtc: lost some interrupts at 1024Hz. Sep 30 14:20:31 fairlight last message repeated 2346 times Sep 30 14:21:32 fairlight last message repeated 3067 times Sep 30 14:21:54 fairlight last message repeated 1148 times IRQ balancing is activated, and the litlle redhat's software for that is installed and running. I have chosen to compile the enhanced rtc in module, and have disabled its graphs because it flooded my logs without any use for me. I have two questions : - Could someone tell me, more clearly than in the kernel help :), what's the use of this HPET beast ? - Does it matter to disable it for real time audio purposes ? Thanks in advance for any enlightenment. Cheers, Y.

[linux-audio-user] Ardour: Stereo or mono inputs ?

by lanas

Folks, Until recently I used to connect one output (L or R) to one mono Ardor input. Then I thought, well, most apps have stereo outs, so why not connect both ? This way Freeverb works ! Apart from that, what do you most often use, mono or stereo ? What's your approach ? Cheers, Al

[linux-audio-user] [ANN]: Kontroll updated

by Florian Schmidt

Hi, this is a small announcement for a minor update for a minor piece of software, and at the same time a question :) So here it goes: Kontroll is a small utility that generates midi cc messages from the mouse position. It is inspired by the MouseX and MouseY UGens in Supercollider. It simply creates an alsa sequencer port which you can then connect with your favourite patchbay. The mouse position is independent of window focus and is relative to the screen origin at the upper left. - Another small update to kontroll. Now the controller and channel numbering range from 1-128 and 1-16 as commonly seen in other midi applications and hardware. previously it as 0-127 and 0-15 which was probably confusing to non computer people. - A minor update to this little program of mine called “Kontroll”. On shutdown it saves the last used parameters to a file called ~/.kontroll and on startup reads it again. This saves setting it up all over again on each start of the program. You can also save special setups via the “File” menu. Grab it here: http://tapas.affenbande.org/?page_id=42 Or directly: http://affenbande.org/~tapas/kontroll.tgz And here's the question: A user suggested (and i'd like this idea very much) that kontroll be able to make use of other input devices attached to the computer (additional mice, joysticks, etc). Now i would like to avoid playing with /dev/input directly, cause i imagine it to be a drag. So does anyone of you guys know a small and easy to use input-library that makes accessing these devices a breeze? If so, please let me know. Regards, Flo P.S.: Ah, LASH support is still missing. Will add it right away (or at least try) ;) -- Palimm Palimm! http://tapas.affenbande.org
