[linux-audio-user] Turning monitoring off - ymfpci

by Allan Baker

Hello all. As I understand it, simply muting the channel (line in or mic) in alsamixer should turn off monitoring of that channel. This is not working for me. I have a YMF-740C soundcard (ymfpci). I am trying to get rid of the 'clean' signal so that for instance I could use pd as an effects processor. Any suggestions/tips/pointers to docs? Thanks

[linux-audio-user] formatting music

by Peter Jay Salzman

please let me know if this is off-topic for this list... i've been using chord to typeset music, and it works well for some types of music, like popular tunes i'm familiar with. it's a great utility and generates really nice output, but i'm starting to need something a little different for things like jazz standards. i'd like to be able to typeset something like: | Dm7 G7 | Dm7 G7 | Em7 A7 | Em7 A7 | | | | | | | % % % % | % % % % | % % % % | % % % % | | | | | | instead of what chord (or guitartex) does: Dm7 G7 Dm7 G7 Em7 A7 Em7 A7 Cigarette holder which wigs me, over her shoulder, she digs me in other words, lyrics are nice, but i'd rather show measures and perhaps syncopation. if i can do both, that would be fantastic. but i'd rather have the concept of a measure rather than the concept of "this chord is played with this lyric". any recommendations about a linux tool that does what i want? pete -- Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D

[linux-audio-user] jack question

by j.c.w.

greetings all, i recently put together a new debian box (unstable with 2.4.19+ll), installed jack from cvs, installed freqtweak 0.4.5, ssm from cvs, pd from cvs, etc. and tried to get them to play together and have had no success. i start jack as follows: wazowski:/home/jcw# jackd -d alsa -d hw jackd 0.40.1 Copyright 2001-2002 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. creating alsa driver ... hw|1024|2|48000|swmon starting engine everything seems to be ok. then i launch freqtweak and get the following: wazowski:/home/jcw# freqtweak -i none,none -n ft JACK error: cannot connect input port: none -> _pcm:playback_18 JACK error: cannot connect output port: ft:in_1 -> alsa_pcm:playback_1 JACK error: cannot connect input port: none -> % JACK error: cannot connect output port: -> alsa_pcm:playback_2 i have no idea what to make of this. once freqtweak is running, i can't get alsa_pcm:playback_1, etc. as options. also, ssm just segfaults if i try to connect it to jack at all. pure data just kills all audio. i am running alsa rc5 with an rme9652 and an emu10k1. all of my apps work perfectly without jack. does anyone have a clue or suggestion? i hope that i have just done something silly and someone will be able to point out the error in my ways. thank you for your time. j.c.w. -- WITH GORILLA GONE, WILL THERE BE HOPE FOR MAN? - ishmael

[linux-audio-user] Gentoo users

by Jason Thompson

Nice to hear that others have put together viable systems on Gentoo. Just one note of clarification--I've managed to compile ardour, but I can't start it up because it's looking for the ardour_ui.rc file in the default place (/usr/local/music/src/ardour) which isn't created with the ebuild. In fact, ardour_ui.rc doesn't seem to exist anywhere on my system. Do you have to build it yourself. If so how? I can't find any documentation. I'm also running the Vanilla kernal. Glad to hear that I'm not the only one who had difficulties with the gentoo kernel. It would be great to put together some music/sound ebuilds for gentoo. Although I'm an intermediate Linux user, I'm not much of a programmer so I'd be happy to volunteer my writing abilities for documentation.

[linux-audio-user] Migration from OSS Pro to ALSA

by Robert Brown

Hi, I am building a new box for audio (Gentoo Linux) and have decided to use ALSA instead of OSS pro which I have always used. Having never used ALSA I was woundering if anyone can offer tips or highlight the main differences. My main soundcard is a M-Audio Delta Dio 2496 (ice1712) and my secondary card is the onboard CMedia 8738. Since Gentoo Linux uses devfs, one concern I have is how to know what device names the input/outputs will have. I have read through a some docs on ALSA and also the ALSA guide on Gentoo.org and they do not appear to address this issue as they are geared for consumer cards it seems. I use the M-Audio often to make DAT > PC (via SPFIF) transfers. With OSS Pro I can just "cat /dev/soundstat" to retrive info about what each device name in /dev actually is. Also, if I understand right, ALSA uses /dev/audio* as well as /dev/dsp* ? I am a bit confused about the envy24control setup as well as how to "unlock" the sample rate for the pro card. I would greatly appreciate any comments or suggestions on making the switch or anything that may be helpful. -- Robert Brown

[linux-audio-user] linux audio on Gentoo

by Jason Thompson

There was a recent discussion here about people using Debian. Frustrated with RedHat, I almost went with Debian, but Gentoo caught my eye. So far I'm really happy with it, though I'm having some difficulties getting Ardour set up. The great thing about Gentoo is that you compile and optimize the entire distro on your computer. The performance boost between Redhat 8.0 (my old distro) and Gentoo is easily noticeable. Plus their optimized kernel includes the low-latency patches. Are there any other Gentoo users out there? If so, I'd be interested in setting up a Gentoo-specific audio listserv to avoid flooding this list with distro-specific issues. Anyone else interested? (Of course I'll remain a loyal linux-audio-user subscriber!)

Nice find Maarten! I want to try this too!

Is this what you mean? http://yoyo.cc.monash.edu.au/~pfh/synaesthesia.html "Synaesthesia is a program that represents music graphically in real time as coruscating field of fog and glowing lines. It is intended as a visual accompanyment to music." It works with line input as well. Maarten ____________________________________________________________________

[linux-audio-user] compiling tao

by Torsten Anders

Hi, tao (physical modeling synth, see http://web.ukonline.co.uk/taosynth/) is still an unique program. Unfortunately it does not compile out of the box anymore.Probably compilers nowadays are a bit more rigorous in handling small syntax errors. Appended are the very little changes I needed to put in the code before I succeded compiling. Although these changes are really tiny, for unexperienced yacc etc. programmers (like me ;-) it may take ages the locate them.
