[linux-audio-dev] q - asfxload/emu10k1/sblive problems

by David McNab

Hi, I'm using a Soundblaster Live! card (emu10k1 driver) under ALSA. The 'asfxload' util works fine for loading a single soundfont. But when trying to load different soundfonts with the '-b1' option, for instance: asfxload -b1 dance.sf2 I get: asfxload: invalid option -- b asfxload: invalid option -- 1 This conflicts with the manpage for [a]sfxload. Also, when I send Bank Select messages from my MIDI keyboard, these get ignored (although Bank Select LSB works when I use fluidsynth). Any thoughts on either or both of these issues? -- Cheers David

[linux-audio-dev] Linux Live CD (Audio)

by Oliver

Hi, forgive me if this question has been asked before: Is there something like a Linux Live CD optimized for and containing audio (editing) applications? Something like this http://www.frozentech.com/content/livecd.php where I can simply insert the CD, boot from it, and start working on my songs? -Oliver Mit schönen Grüßen von Yahoo!

[linux-audio-dev] A bit of good news

by Ivica Ico Bukvic

Hi all, Just found out that I will be presenting a paper titled "Linux as a Mature Digital Audio Workstation in Academic Electroacoustic Studios - Is Linux Ready for Prime Time?" at the upcoming ICMC2004 (International Computer Music Conference) this fall. Although I have only 3 more days to do final editing for the camera-ready paper :-(, if you have any ideas or thoughts for additions to the paper I will certainly read through them and try to add them (if they are not already included). I will be also posting a preliminary draft as soon as it exits the realm of "ugly" ;-) Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico/

[linux-audio-dev] LADSPA proposal ...

by Paul Davis

well, it appears that there is little to no response to the proposal from the LADSPA meeting at ZKM. just to be sure that the silence is an accurate reflection of what people think, i want to take a harsh stance on the proposal and see if it generates any response... if we follow through with the proposal, LADSPA will no longer be a header file. it will require the use of a library. the actual struct in the header file will contain the absolute bare minimum information required to actually run a plugin, nothing more. No port names, no hints, no default values. we will try to make the library self-contained, dependency-free, but it will still be more complex than the current model. moreover, there will be 2 versions of LADSPA floating around, thus leading to problems with host/plugin compatibility issues. personally, i think its worth going through this pain. we will end up with a system in which new LADSPA extensions do not require changes to the API, which is a great thing. but it will be painful to get there, and i want to check that people don't mind doing it. --p

[linux-audio-dev] Re: [fluid-dev] question - soundfont editing

by Tim Goetze

[David McNab] >Can someone please recommend a program for Linux which can easily take >presets from one or more existing soundfont files, and compile them into >a new soundfont file? with about 10 lines of python (plus a few to name the presets you're after) you can do such tricks with this little helper here: http://quitte.de/file-formats/SF2.py at the end of the file it shows how to extract one preset into a separate .sf2; modification for many presets/sf2 files should be straightforward. cheers, tim

[linux-audio-dev] Info required: FLAC on W*****S

by Alfons Adriaensen

Hello list, I'm involved in a (friendly) debate on the surround sound list. One the main contributors of this list, Angelo Farina (univ. of Parma, Italy) wants to make available some interesting 4-channel recordings he recently made. The distribution format has to be lossless. I already pointed him to FLAC and the Windows tools available for this format. He tested these and has some objections: - The codec does accept WAV, but not WAV-EX files. - There seems to be no Windoze player that can handle 4 channels FLAC files directly. I'd like to exert some gently pressure towards an open source format, but then I'll need some answers to these problems. So if anyone has some information about this, I'd like to know. All this may be a bit OT, so maybe the best thing is to contact me by email. TNX, -- Fons

[linux-audio-dev] Problem modprobing latency-test module for the latency benchmark: rtc -> no such device

by Ivica Ico Bukvic

Hi all, I've been trying to benchmark my notebook with the latency-test. However, after a successful compile, instructions tell me that I need to install the latency-test module before running tests. Yet, if I do modprobe latency-test, computer complains about rtc module saying "no such device" and ultimately fails to install the latency-test module which depends on rtc. I am using 2.6.5-mm5 kernel with some additional patches, none of which should necessarily affect the real-time clock (is that what rtc stands for?). The processor is mobile amd64 and the kernel when either compiled for i586 or K8 chips exhibits in both cases the same symptom. OS is Mdk 10.0 (community with all the patches that should bring it up to par with the official release, at least I think so). Any ideas?

[linux-audio-dev] Copland

by Jens M Andreasen

Hi! Anybody here got an old enough recording of Coplands "Rodeo" that can be freelee released? ... I just came back from Stockholm City Theaters version of Hamlet ... Wow!! I would say to you guys: If you are around here, and are into percussion, go see it! The music is well written and the sound is clear and enjoyable ... Back to Copland: I tried to find "Fanfare to the Common Man", and found an excerpt (appearently enough) to convince my better half that Copland has deeply influenced both modern jazz as well as rock-music (as well as the theater music we just heard.) Surely there must be more out there? No? mvh // Jens M Andreasen

[linux-audio-dev] q - Selecting soundfonts via MIDI

by David McNab

Hi, It's my understanding that on synth devices (eg fluidsynth, and the memory on loaded soundcards), one selects a sound via MIDI 'program-change' events, and can select a bank via MIDI 'controller change/bank-select-msb' events. However, when I have fluidsynth loaded with more than one soundfont file, how do i select sounds from different banks within different soundfonts? I've tried all different combinations of program-change, controller-change/bank-select-msb and controller-change/bank-select-lsb, but nothing seems to work. Ditto, how do I achieve this via the ALSA Sequencer API? (I've already asked on the ALSA list, but people side-stepped the question). All help appreciated. -- Cheers David
