Re: [linux-audio-user] Stable driver for USB Quattro?

by nick

What's this card like in use, especially in terms of latency? Do you use it with JACK at all? If so what kind of latencies can you go to stably?

[linux-audio-user] Stable driver for USB Quattro?

by Denis de Leeuw Duarte

Hello, I have a USB Audio Quattro, but I haven't been successful at getting it to work yet. Are there any of you that have a working Quattro? I'd like to know which driver versions you have. I tried ALSA 0.9.1, 0.9.2 and 0.9.3a.

Re: [linux-audio-user] No state is present for card

by Denis de Leeuw Duarte

Well I fixed the access problem quite easily last night actually. This might be a bit distro dependent since not all of them use the devfs, so ymmv. In /etc/devfsd.conf add this: LOOKUP snd MODLOAD ACTION snd LOOKUP dsp MODLOAD LOOKUP mixer MODLOAD LOOKUP midi MODLOAD REGISTER sound/.* PERMISSIONS root.audio 660 REGISTER snd/.* PERMISSIONS root.audio 660 Which then gives access to the audio group automatically. Add yourself to the audio group and you're done. It didn't seem to work with me at first, but I just had to log out of my kde session an login again and then it worked. >From: Patrick Shirkey <pshirkey(a)boosthardware.com> >Reply-To: linux-audio-user(a)music.columbia.edu >To: linux-audio-user(a)music.columbia.edu >Subject: Re: [linux-audio-user] No state is present for card >Date: Sun, 25 May 2003 15:07:34 +0900 > >Denis de Leeuw Duarte wrote: >> >>> >>>"State" means the current mixer settings, but the Quattro doesn't have >>>any >>>mixer elements.

I've been struggling with this device for a week. First I had to return it to the store because they gave me the wrong power supply and probably a defective unit. I'm very glad it works now.

[linux-audio-user] Weird multitracking problem with Audacity

by Ross Vandegrift

Hello all, I was working on recording some vocal harmonizing with myself yesterday and ran into a weird problem with audacity-1.1. If I'm recording 3-4 channels at once, I can stop it and record an additional take over that and everything is fine. If I record one channel and then try to do a second one, the second one sounds like it was a setup with the incorrect sample rate - it sounds like someone slowed the track down and dropped the pitch extra. Anyone know what's going on? -- Ross Vandegrift ross(a)willow.seitz.com A Pope has a Water Cannon. It is a Water Cannon. He fires Holy-Water from it. It is a Holy-Water Cannon. He Blesses it. It is a Holy Holy-Water Cannon. He Blesses the Hell out of it. It is a Wholly Holy Holy-Water Cannon. He has it pierced. It is a Holey Wholly Holy Holy-Water Cannon. He makes it official.

[linux-audio-user] No state is present for card

by Denis de Leeuw Duarte

Hello again, By the looks of it, the new alsa 0.9.3c snd-usb-audio driver loads correctly with my Quattro, but I get this message when running the alsasound script: "No state is present for card Quattro". I have the impression that the documentation on the alsa site for .asoundrc doesn't really cover the newer asound.state file, is that correct? For instance, alsa looks for a state.Quatto{} clause in asound.state, but I can't find anything in the documentation about this state clause. I don't really know what to put in it. I tried Patrick Shirkey's .asoundrc file from the Wiki but that doesn't work. Any ideas? Thanks in advance and regards, Denis de Leeuw Duarte _________________________________________________________________ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail

[linux-audio-user] MIDI-splitter

by Emiliano Grilli

I think this could be of interest... I've been recently contacted by a visitor of my site that asked me if timidity can render into wav single channels/tracks of a midifile instead of the whole midifile. I know that timidity can't do this and then pointed him (his name is Pasquale Fersini) to the MIDI::Perl module site. Then he contacted the author (Sean M. Burke) and they write a simple utility for splitting midifiles into separate midifiles based on tracks/channel information. For those who are programmers this can be a simple thing, but for those (like me) that are using Linux as users, I think it's a very handy utility. Here you can find the script: http://members.spinn.net/~sburke/midi_splitter.pl and here the announce on the MIDI::Perl ML: http://archive.develooper.com/midi@perl.org/msg00205.html HTH -- .-----------------------. | Emiliano Grilli | | emillo(a)libero.it | | Linux user #209089 | | http://www.emillo.net | '-----------------------'

Re: [linux-audio-user] newbie q: making a machine

by Jonathan Segel

i own RME hardware, so that's a plus! i was thinking about building a new machine that would be dedicated to being an audio maker. the mac running ydl is a 9600, but it has a digi AMiii card which i'm sure is useless to anything else but digi. (got the machine to run os x w/ digi's coreaudio though...) and yes, i'm a professional musician. i've been tryign to sneak max/msp and supercollider into the pop world for a while now. and now supercollider server is being developed, there are already working linux ports of the synth server side (so i'm told) but not the language side.. > >Jonathan Segel wrote: >> hi, i'm a recent linux user, coming from mac universe. i started by >> putting YDL on one of my old macs last summer, but now i'm gonna get >> serious. >> so my question is: what parts would you recommend for making a Linux box >> to run audio on? i realize this is a big field, but any clues are helpful. >> also, i'm probably going to use redhat, given that my ydl exprerience is >> based on redhat. any precautionary measures? >> >> thanks all > >Redhat is an ecellent choice esp if you get into the planet ccrma catalog. > >The question of hardware really depends on what your intentions are.

[linux-audio-user] Notation to freqs/Rosegarden

by Juhana Sadeharju

Hello. How to convert the notes in http://www.funet.fi/~kouhia/arabicscales.png to keyboard's keys, MIDI values, and frequencies? In Rosegarden, I tried to type the notes in, but Rosegarden accepted only two first notes and then did not accept further notes. Rosegarden had no that overtone symbol seen in the image. It would be great if one could type whatever he sees, and only afterwards Rosegarden would let user know if the notation makes sense. By the way, I tested Mounted by the Gods (www.mountedbythegods.com) loops ftp://ftp.funet.fi/pub/culture/music/western/Yello/mountedbythegods.tar.bz2 (or http) in Rosegarden: (1) How to set the tempo? Is it 120 with those loops? Setting tempo based on the loop length did not work; tempo went to 60 instead of 120 in some random manner -- a bug? (2) Does MIDI and JACK delays affect the syncronization between the loops? Now the mix sounds a bit out of sync and maybe is skipping. Hmmm.. a deng loop fills entirely the space but claps loop does not (or otherway; try drum loops as well). What happens is that the claps loop pauses for a while when I arrange many of them to a row. Can you figure out if this is exactly what is intended? I'm in a believ that I should not time-scale any of those loops. It could be that the deng and the claps loops are all ok, but what I hear skipping is the Rosegarden audio engine. Is it as good as possible? Best regards, Juhana
