I think it's a nice idea to add support for scale files to the M_quantizer class (and remove the 12-tET restriction). See http://www.xs4all.nl/~huygensf/scala/scl_format.html Manuel

[linux-audio-user] Uhm, low latency?

by felipe

Hi, I was stupidly sure I was running a lowlatency kernel just because my /proc/sys/kernel/lowlatency was set to 1. I used to start jack with something like $: jackd -R -d alsa -d opl3sa2 -r 44100 and I was surprised by the great number of xruns. Now I tried "jackstart" as root and... what? This kernel does not have capabilities enabled?! I read some posts by people who got lowlatency in their laptops only after enabling ACPI... Could this be true for some PC's too? Has anyone faced this inconvenience? I've completely disabled the Power Management support. My box: Pentium III katmai 192 MB Ram Sound Card Yamaha opl3sa2 hdparm -t /dev/hda -> 64MB in 4.21 secs = 15.21 MB/sec Debian woody + gcc3.2 + DeMuDi ALSA 0.9rc6 Kernel 2.4.20-ck2 (almost: it's a 2.4.20 vanilla with Con Koliva's lowlatency, preemtpible and arcangeli's VM patches) Can't think of anything relevant, any idea?

[linux-audio-user] trident

by Alexandre Prokoudine

Greetings, Where can I get information, whether the ugly SiS 7018 (Trident) supports MIDI inside? There's nothing about MIDI at http://www.alsa-project.org/alsa-doc/doc-php/template.php3?company=SiS&card… I've just got the beast running with ALSA drivers, but without MIDI yet :-( Thank you in advance! -- Alexandre Prokoudine ALT Linux Documentation Team JID: avp(a)altlinux.org

[linux-audio-user] How about creating a sound-patch repository?

by Robert Jonsson

Hi all, The topic of the day is softsynts! I've got this trouble with all softsynths available today under linux: -there aren't nearly as many patches available as I'd like. Some of them don't have any patches at all. Now, this could be due to good reason, a lot of the synths are rather young. - patches may not be supported yet - patch formats change all the time making it hard to keep up - ... Some synths do seem to have very good patch systems, some of them come with a few patches, some several... Oftenly though, the patches are more proof of concept or tutorial types than finished, usable, sounds. Anyway, in general I think the available patches are way to few! Speaking for myself I only have very limited time to poke around with sound apps. When I do have time to do some audio stuff it would be a great booster if there where more patches available for the increasing amount of softsynths. Some of the synths are just way to complex for me, I will never understand how to utilize them (all these modular whizbang hitech synths). Though I'm sure great sounds can be produced with them. Note that I'm not blaming the authors for not including patches! They are doing a great job at creating the synths in the first place! (Ofcourse it's great if they have created some nice patches also, but that is another issue, they are then working double shifts as users also :-). I was more think along the lines of community effort. We, the users, should be able to help ourselves by helping each other. So... I throw out the question about a centralized sound-patch repository. What if we provided a site similar to e.g. themes.org? Interested parties should there be able to upload patches and associate them with the synth they are made for. This should then be published on a searchable web. We've talked before about application databases ala freshmeat, this could be a part in such an endevour. Some synths are getting to the point where they have a community of their own, though I think this is the still the exception, not the rule. By introducing a central repository a lot of extra publicitiy for all "smaller" softsynths, and linux audio in general. It may very well be that we as a community are still to small to support things like this, but I'd like to think we have reached critical mass. What do you guys think? Any takers? Regards, Robert

OK, I'm crossposting this to LAU because I think there are lots of people who might provide some valuable input. you can subscribe here: http://www.linuxdj.com/audio/lad/subscribelau.php3 Let's continue it there, OK?

Getting the lowest cost & highest quality studio is everybody's concern. Unfortunately, when you're on a low budget you have to make a compromise here and there. I didn't really think hard about it but I don't think there should be an OpenStudio 'standard' in terms of equipment, software and such. People could provide lists with reccomandations for various setup issues, low cost equipment etc but the setup will depend on every studio's needs nad technician/engineer/director's preferences. > > So what I ask you Kai, Justin, Michael, Tom Poe and all you open-sound fans is > something like an "OpenStudio HOWTO", that would provide a basic framework > with the best solutions for setting up a (network oriented?) home recording > studio, covering both hardware and software issues. In my previous post I threw an idea, very lightly, about an OpenStudio Gazette and Tom picked up on it and now I started brewing some ideas about it. I think that it'd be very useful to reach people and provide information, share ideas/experiences, success sotires (both studios and artists) and stuff like that. So, since last night and today I was thinking about this for the gazette: 1. having short articles deling with: a. legal issues for artists - copyright laws, various artistic licences etc explained in plain english (& other languages if translations become a reality b. software/equipment/setup issues 2. tips and tricks for setting up and running such studios 3. aesthetic type of essay on a related topic 4. announcments, classifieds and things like that and maybe even ads for OpenStudio friendly gear for sale/buy and such. We could seek contributions from the Linux, open source, alternative licences people and release it on a monthly or bi-monthly basis (depending how much contribution & content we can pull). I could take a plunge at an article once in a while. > > I could help translating it into Italian and Spanish, or if none is willing > to, I could start writing the basis and then we could fill it up together, > but I'd like to hear what do you all think first.

Re: [linux-audio-user] ardour localization

by Martin Wolters

Alexandre, emails to your address avp(a)altlinux.ru always bounce. I hope you still monitor this mailing list. Please see my previous (bounced) emails below. All: I would like to participate in ardour localization, but I can not access the cvs repository due to some security limitations on our network. I would really appreciate to get a tarball somewhere. Maybe even with daily snapshots - that's almost like CVS read access. Thanks. -M -------- Original Message -------- Subject: [Fwd: Re: [linux-audio-user] ardour localization] Date: Fri, 31 Jan 2003 09:17:24 +0100 From: Martin Wolters <wol(a)codingtechnologies.com> To: Alexandre Prokoudine <avp(a)altlinux.ru> Hi Alexandre, die letzte email die ich versucht habe Dir zu schicken (s.u.) ist leider gebounced. Ich habe noch eine Bitte: Ich wueder gerne mit ardour helfen und habe mittlerweile auch ALSA 0.9 und jack installiert.

[linux-audio-user] [ANN] swh-plugins 0.3.4

by Steve Harris

http://plugin.org.uk/releases/0.3.4/ Hods of changes, including: * Bugfixes to GSM sim (Pascal Haakmat) * Bugfixes to FM osc (Pascal Haakmat) * Bugfixes to audio divider (Nathaniel Virgo) * Added another compressor, SC4, stereo, no sidechain * Added lookahead brickwall limiter * Added L/C/R delay (requested by Marek Peteraj) * Added Giant flanger (kind of requested by Patrick Shirkey) * Added DJ Flanger (actually requested by Patrick Shirkey) * Should now compile on FreeBSD * Fixed syntax error in RDF metadata, works with Bob H's jack-rack now I've updated the AUTHORS list, but I've undoubtedly forogtten people, so if youre not in there and should be give me a shout. SC4 is more-or-less like SC3, but has no sidechain and a subtly different algorithm. The sidechain was confusing hosts. The limiter has up to two seconds of lookahead, so can be very gentle. The L/C/R delay might be a bit familiar to Korg Trinity users ;) I haven't used it much bet it seems pretty cool. The giant flanger was a mistake, but I left it in anyway. The DJ flanger hjas controls for LFO period (instead of frequency as you would have in a synth) and you can resync the LFO by clicking a toggled control*. - Steve * This reminds me, there would be a use for a MOMENTARY hint (implying or requiring TOGGLED) in LADSPA, that meant that a control port should only be held high while the UI control was held down, otherise you have to double click reset controls, which is confusing.

[linux-audio-user] enhanced CD--update

by Anthony Perez-Miller

Hello all, Thank you for all the advice on how to access the tracks on the Peter Gabriel disc. As it turns out...I missed the obvious. Unlike usual music CDs, this one has to be mounted (as Alexandre Prokoudine pointed out). Once mounted, the audio tracks are visible, after all. Grip using cdparanoia turned them to ogg files without a complaint. Can't guarantee that it will be that easy for all encoded CDs, unfortunately. But at least I'll be looking at the fine print before purchase from now on. thanks again, --Anthony
