hello friends, i have successfully built timidity (2.12.0), then jack (0.34.0), and finally muse --with-jack (0.6.0pre5). timidity works by itself, i can play midi files and it sounds. my intention is to use it as a software synthesizer for muse, so i launch it with the option -iA. but muse also requires jack to be running, so first i invoke jack like this: jackd -R -d alsa -d hw:0 and then i can run muse. the problem is that as soon as i have jack running timidity doesn't sound. all right, the real problem is that i never got to fully understand jack, so i have no idea how it works or how i can make things work together. as soon as i begin more confused than before so i give up. any charitable soul could give me a quick hint on how i should invoke timidity and/or jack so that i can use the combination of the two as a software midi device for muse? (i used to use it like this in the past, but that was without jack coming into play) thanks for any help. best, lj

[linux-audio-user] question about off-topic email

by Peter Jay Salzman

hi all, i know that music theory is off-topic for this list. generally, how tolerated are off-topics posts on this list? i've been experimenting with some new theory i've learned and wanted to know why something sounds terrible. if this list wants to be totally on-topic (which is understandable), can someone recommend a flame-free mailing list for people who want to ask questions about jazz theory? my teacher doesn't have an email address, and i'd like to get an answer before my next lesson. :) sorry for asking, but i'm very new to this list and don't know the group dynamic yet. pete -- Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D

[linux-audio-user] jack module player v0.1b

by janne halttunen

Hello all, here we go, another release of the hackish jack module player. What's it about? JMP is a MOD-player outputting each channel individually to jack. This is achieved using xmp module-player's channels soloing feature, and ecasound's multitracking abilities. New features in v0.1b -channel-naming: now you can see channels in jack with the names you assign to them in commandline -sticking channels together for better performance: maybe you don't need EVERY channel showing separately in jack -better error recovery: should leave no dead processes hanging around (NOTE: kills all xmp processes on exit, be careful! ecasound is left in peace..) -------------------- # ./jmp.py --help Jack Module Player v0.1b usage: jmp.py [options] module-file(s) jmp.py options: -b, --buffer set buffersize -r, --rate set sample rate -c, --channels override module's number of channels -N, --names name individual channels (or channels sticked) with comma separated list of names e.g. bassdrum,hihat,snare -S, --stick stick individual channels together with colon separated list of channel-numbers e.g. 0-3,5:6,7:8 (channel-numbering starts at 0) -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/ # ./jmp.py /home/janne/biisit/wik.xm --names bassdrum,hihat,hihat,snare -c 4 ... # jack_lsp alsa_pcm:capture_1 alsa_pcm:capture_2 alsa_pcm:playback_1 alsa_pcm:playback_2 ecasound:bassdrum_1 ecasound:hihat_2 ecasound:hihat_3 ecasound:snare_4 ------------------- Get it from http://www.pp.htv.fi/jhalttun/jmp.py ..still coding when should be making music :) janne

hi, i want to connect my keyboard to my pc (sb Live!) in oder to use it as a softwaresynthy. i've read aconnect 64:0 65:0 should do this ... but: stef: ~ $ aconnect -lio client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' Connecting To: 63:0 client 65: 'Emu10k1 WaveTable' [type=kernel] 0 'Emu10k1 Port 0 ' 1 'Emu10k1 Port 1 ' 2 'Emu10k1 Port 2 ' 3 'Emu10k1 Port 3 ' i can't find this port 64:0. here is my the alsa passage of my modules.conf: # ALSA portion alias char-major-116 snd alias snd-card-0 snd-emu10k1 # module options should go here # OSS/Free portion alias char-major-14 soundcore alias sound-slot-0 snd-card-0 # card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss #my own settings alias midi snd-synth-emu10k1 alias snd-synth-midi snd-seq-emu10k1 alias snd-seq-midi snd-seq-emu10k1 (i tried it also without the "alias midi snd-synth-emu10k1" line) i compiled alsa with ./configure --with-cards=emu10k1 --with-sequencer=yes;make; make install i use debian sid. what am i doing wrong? with muse i can use the /dev/snd/midiC0D0 for recording thank you stefan

I thought that I remembered that the Midiman Audiophile 2496 had been working with spdif for a while for me at least, though I have the dat on the Delta 1010 in the music room now. I know that there was a lot of ups and downs with the drivers and spdif at first. I did have to cook up my own .asoundrc for it, but that's kind of expected with a mutichannel chip being used on a simple card. Tracey

[linux-audio-user] Straight-talking digitally

by Paul

Hi all, This might seem like a silly question, but I'm having an unexpectedly hard time putting together something I consider to be quite simple in essence. The intent: play music from PC (eg .ogg/.mp3 etc) via S/PDIF to an external DAC, and thence to sound system. The problem: finding a soundcard supported by Linux and which offers the option of unadulterated digital output. Ie. I want the soundcard to simply stream the bits at 44.1Khz (or 48) and not shag around with it in any way. My current setup is a compromise. I have onboard sound with a VIA8233 (Avance AC'97) 6ch chipset, and am using Windows XP with this, since the latest ALSA driver doesn't produce any sound on the S/PDIF output (although the optical port lights up). Trouble is, I don't trust the Windows driver, since the control panel for it allows me to select DSP environments and use a graphic equaliser. With the environment set to "none" and the equaliser off is it providing a "pure" bitstream un-molested in any way? Who knows. So, the question to you is simply: do you know of any soundcards which would fit the bill - ie. with a fully working Linux driver, and known to be configured to produce "pure" digital out. Cheers, Paul. -- Lubarsky's Law of Cybernetic Entomology: There's always one more bug.

[linux-audio-user] ISO images from Audio CD's?

by Dave Price

Good morning, I read (somewhere) that it is possible to make a directly useable Hard Disk 'Image File' from an Audio-CD. I am familiar with mkisofs for sets of data files and mounting the iso-9660 images as loop(ed) devices to access the files within the resulting image file. Also, I know that cdrdao builds a .bin temp file when you make a copy ... Are these files interchangeable? How would one mount an Audio 'image file' to play it, since you usually do not mount Audio CD's - players like xmms just use the raw device (right?) Any hints or pointers (urls) would be appreciated. aloha, dave

[linux-audio-user] [ANN] ams-1.5.5 fixes serious bug

by Dr. Matthias Nagorni

Hi, ams-1.5.5 is available from http://www.suse.de/~mana/kalsatools.html. It fixes a serious bug in synth.cpp which causes the machine to freeze when ams is started as root. Some example patches for the bode frequencer LADSPA plugin included in the new 0.3.3 version of Steve's plugin set have been added as well. Have fun !

[linux-audio-user] mp3 live-encoding with sox and lame

by Christoph Rupp

Hello list! (I have searched for an answer to this question in google and some other lists but didn't find something helpful... sorry if this has been asked before) i want to have realtime-encoding of my soundcard line-in with sox and lame (or something similar - i need command line tools). Now i use rec -t wav -r 44100 - | lame -m m -a -b 64 - (i need 44.1 khz/64 kbit). But all 5 or 7 hours sox crashes; there's an older thread on the sox mailing list: http://sourceforge.net/mailarchive/forum.php?thread_id=1083489&forum_id=3958 which says that this is due to a counter in the wav header which overflows and that you should use .raw instead of .wav. But whatever i use doesn't sound right: sox -t ossdsp -w -s /dev/dsp -t raw -r 44100 -c 2 - | lame -r -m j -b 64 -x -s 44.1 --resample 44.1 - It sounds dump: http://www.kochenmachtspass.de/test3-ms.mp3 I have tried many other options like -c 1 (leads to noise) but i cannot find a solution... Maybe someone of you knows a solution? Thanks Chris ===== http://www.crupp.de __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
