[linux-audio-user] [pw_lists@slinkp.com: snd-usb-audio and Midiman Oxygen]

by Paul Winkler

sorry for the crosspost, but i'm not getting any response from alsa-user list and I know these devices have been discussed here before. I've searched the archives thoroughly, but found no report of anyone succeeding in using an oxygen via usb with recent version of alsa. Is that still the case? --PW ----- Forwarded message from Paul Winkler <pw_lists(a)slinkp.com> ----- Subject: snd-usb-audio and Midiman Oxygen Date: Sun, 8 Dec 2002 02:01:55 -0800 From: Paul Winkler <pw_lists(a)slinkp.com> To: alsa-user(a)lists.sourceforge.net Mail-Followup-To: Paul Winkler <pw_lists(a)slinkp.com>, alsa-user(a)lists.sourceforge.net I picked up an Oxygen today, and I seem to get as far as getting the firmware loaded (via midisport_firmware) and loading the snd-usb-audio module, but I don't seem to be able to actually use it. I have kernel 2.4.19, with the latest hotplug and fxload sources from the hotplug sourceforge page (not from cvs).

I'm (relatively) new to Linux, so I've come to the conclusion that I need to put seqencing and more compicated things like that in the future. Having ecasound (on my main computor) and my (now finished) dedicated RTSynth box together I can do it like they did in "the old days" while I slowly try out (and learn) more advanced things now that I finally upgraded from SuSE 6.4 to SuSE 8.1. That upgrade was like opening up pandora's box. > ditto for the introductory material for terminatorX, Mix, Ceres, > Cecilia, and some others. They happen to be programs I haven't tried. So those chapters will introduce me to those programs. > The book is very weak with regard > to technical aspects of ALSA, nor does it offer much to the > would-be developer. I hope to change that aspect in v. 2.0. Perfect! Being that I've been using SuSE 6.4 (up to the upgrade) I haven't even approached alsa yet. And I don't want to until I *have the time and attention* it deserves. I'll read the other chapters and get aquainted with what has come before (again... I'm still kind of a newbie). Meanwhile oss is allowing me to get things done. You've given me an outline of what to look for (in your book) and what to keep in mind as being (possibly) out of date. I will focus on those chapters. Maybe by time I'm ready to focus on the more newer developments, the new book will be out. > I suppose a lot of the material is most useful as starting points, As a (seasoned) newbie, I'm sure it will help. I've jumped right in the middle of all this and need some starting points. I'm in this for the long haul, so I don't mind getting the background on the fundimentals.

I'm not familiar with the -z:nointbuf but I've had exactly the same noise as you described and I was able to get rid of it with the -b option. It was tricky though. I stared with -b:64 (didn't work), then I doubled to -b:128 (didn't work). To make a long story short, after doubling for a while, I ended up dropping the number by 100, then by 50... until I narrowed it down to the _exact_ buffer size that stopped the clicking. It may be different for you, but I think the number that worked for me (at the time) was -b:150. BTW, they say that the -b option works best with even numbers.

Yea... if you're putting a "line level" device (sometimes marked as "aux") into a mic input, you are sending a higher voltage level into than the mic input is designed to take. I think you could actually damage something (possibly). Rocco __________________________________________________________________ The NEW Netscape 7.0 browser is now available.

[linux-audio-user] Jack module-playing fun

by janne halttunen

Hi all, despite of my hunt with google, I just couldn't find any module-player with jack-support. So, I wrote a small script. The xmp module-player allows for playing individual tracks from a module-file, and ecasound gives them out to jack. Yeah, it is an ugly hack, (better would be jack-support to xmp) but it sort of works (though not perfectly: connecting ports is slow). --cut-- # python jmp.py --help xmp.py options: usage: xmp.py [options] module-file -b, --buffer set buffersize -r, --rate set sample rate -c, --channels override number of channels -l, --looping loop module -n, --noconnect don't connect jack-ports to alsa-playback -q, --quiet -v, --verbose NOTE! external programs required: Extended Module Player: http://xmp.sourceforge.net/ Ecasound: http://eca.cx/ # python jmp.py /home/janne/biisit/drumble.xm --looping Jack Module Player v0.1a connecting ports........done. # jack_lsp alsa_pcm:capture_1 alsa_pcm:capture_2 alsa_pcm:playback_1 alsa_pcm:playback_2 ecasound:xmp_1 ecasound:xmp_2 ecasound:xmp_3 ecasound:xmp_4 ecasound:xmp_5 ecasound:xmp_6 ecasound:xmp_7 ecasound:xmp_8 --cut-- Get it here: http://www.pp.htv.fi/jhalttun/jmp.py cheers, janne

[linux-audio-user] [admin] list policy, non-member posting

by J�rn Nettingsmeier

hi everyone ! lately, the number of posting attempts from non-members has risen to a point where i'm just rejecting them without reading each one and checking if it's on-topic or has already been sent to the list from another account. our current list policy is members-only posting, for the following reasons: * i believe people who want to profit from a community should take part in it * spam prevention. so far, it has saved everyone from about .5k spam msgs. a number of list subscribers seem to post from different addresses, so some of their mails are being rejected. if this applies to you, there is always the possibility of subscribing multiple addresses and disabling mail delivery for all but one via the web interface. best, jo"rn -- J�rn Nettingsmeier Kurf�rstenstr 49, 45138 Essen, Germany http://spunk.dnsalias.org (my server) http://www.linuxdj.com/audio/lad/ (Linux Audio Developers)

[linux-audio-user] playing chords to help practise improvisation

by Peter Jay Salzman

hi all, i just started to play around with jazz improv. what would be really useful is if i can define a set of chord changes: Dm7 G7 Em7 A7 Am7 D7 Abm7 Db9 and have my computer play it over and over again so i can improvise over the key changes. it would be great if... it can loop: so i don't have to record the progression 100 times if i want to play around with this 100 times. the timing can change wildly: i can't really do much at the speed which i normally play "satan doll". the chords come too fast. and it's hard playing chords unnaturally slow (although i suppose that might be a good thing to practise). there were some kind of quarter note percussion that gives me a beat so know when the chord is about to change. it doesn't need to sound good at all. my improv should sound good. ;) is there an app i can use for this purpose? pete -- Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D

[linux-audio-user] Re-encoding Stereo mp3's into Mono mp3's

by Steven P. Ulrick

Hello, Everyone :) My question is, is it possible to take an already existing mp3 (128 kBits, 44.1 kHZ, joint stereo) and re-encode it so that it is in mono (at 128 kBits of course). I figured out how to accomplish this task by using the command mpg123 -w to convert the mp3's into wav files, and then I use the following command to encode the wav file into a mono mp3: lame -b 128 -m mo (In both cases, of course I used the appropriate file names, in the appropriate order) What I would like to do, is re-encode the stereo mp3's directly into mono, without having to go through the time consuming step of converting the mp3's into wav files. In case you were wondering, one of the reason I want to do this, is that I have some old gospel songs from the early to mid sixties, and, like a lot of music from that era, the stereo is really cheesy: for example, almost all the instruments in one channel, and all the vocals in the other channel. This example is a bit extreme, but if you've ever heart "Left My Sins Behind Me" by the Alex Bradford Singers, you'd see why I want to convert to mono :) Thanks in advance for your help :) Steven P. Ulrick

[linux-audio-user] Hammerfall HDSP 9652 Installation

by Mark Knecht

Hi, My new Hammerfall HDSP 9652 arrived. (The new PCI card, not the DigiFace/MultiFace configuration.) The Alsa Card Matrix says it's supported, but the version of alsaconf (0.9.0-1) installed on my system does not recognize it. Questions: 1) Does a newer version of alsaconf support this directly? 2) Can that version of alsaconf be installed without changing the version of Alsa that I'm using? (I'm rpm based from the Planet and don't want to break dependencies if possible.) 3) Is there a simple, straightforward way for me to install Alsa support for this card by hand? If so, where might I find the instructions? Thanks in advance, Mark
