I'm frustrated trying to send the audio output from Gnome Wave Cleaner to my HDSP. I've tried specifying: plughw:1,0 plughw 1,0 hdsp_analog (as defined in my ~/.asoundrc) But none of this works. What am I missing? All suggestions gratefully appreciated.

It won't, at least on my machine. It would be interesting to know the command line options used with arecordmidi. It creates SMF format 0 by default. If you add the -s, (--split-channels) option to the command line, it creates SMF format 1. Regards, Pedro

converting MIDI file format 0 to 1?

by Paul Coccoli

Does anyone know how to convert a MIDI file from format 0 to 1? KeyKit produces the former, seq24 can apparently read the latter. I want to get sequences I generate in KeyKit into seq24. A command line tool would be best, but any suggestions are welcome.

more silliness from Studio Dave

by Dave Phillips

Greetings, I'm teaching loop-based composition to some of my students, so I whipped up this funny example for them : http://linux-sound.org/audio/funcularity.ogg The drum loops are from a Beta Monkey collection, the bass parts are from Tony Sferlazza's page, and everything else is from Freesounds. Ardour2 did the heavy lifting, with assistance from ReZound and Rosegarden. Btw, Rosegarden's tools for loops are beautiful, especially the Set Tempo To Audio Segment and of course the Stretch/Squash tool. Very powerful combo, my compliments to the chefs. As always, vast thanks to the great developers who have given us these fabulous programs. Best, dp

Behringer UMX61

by Ricardo Lobo

Hi everyone, I'm new to linux and audio linux, and I'm a first time poster to this mailing list. I'm trying to hook up the Behringer UMX61 MIDI controller to my laptop running Ubuntu 7.04, but I am clueless about what to do after connecting the USB cable. I believe Ubuntu is not recognizing the device. I tried lsusb and it doesn't show up in the devices. I search the web in vain. Any clues? Cheers, Lobo **

compiling list of console apps

by Julien Claassen

Hi everyone! I'm just compiling a list of audio console/commandline apps. You'll find it below. Thing I'm asking is: Is there anything major missing? Thanks in advance for taking a look. Audio/video players: aplay, alsaplayer, ecaplay, mplayer, sndfile-play, sox, mikmod, xmp (extended mod player) Midi tools: midish, timidity, mondrian Audio recording/processing/mixing: ecasound, applyplugin, csound, DSSI-plugins (some) Synths: fluidsynth, csound, linuxsampler, ZynAddSubFX (basically), Common Lisp Music, Other multimedia apps: youtube-dl, clive (again flashvideo-extraction), theora-encoder, mencoder I know, that I missed some of the bigger synth-programming languages. But besides that, did I miss anything vital here? Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

Almost, you have to write "make CONFIG=Release". > when finished, i entered mammut/src and typed ./Makefile.linux. Almost here too. You have to write "make -f Makefile.linux". Sorry about this. It should have been mentioned in the INSTALL file.

Record at 44.1 or at 48 kHz?

by Victor Roetman

I know this is a subjective topic, but I've done a bit of reading on the web and searching in the archives, and it's not easy to get anything concrete. I understand that recording at high sampling frequencies such as 96kHz may be beneficial, especially with regard to digital filtering artifacts, but for someone like me it's definitely overkill. I also understand that recording with 24 bit samples has definite merit and should probably be done irrespective of the sample rate. The question I have is whether I should be recording 24 bit audio at 44.1 kHz or at 48 kHz if the end result will be Compact Disk audio. It seems that some pro-audio equipment tends to prefer 48 kHz, and many people do their recording at 48 kHz. The heart of the question is this: Will the slight slight increase in quality of recording and mixing at 48 kHz outweigh the slight reduction in quality from re-sampling 48 kHz to 44.1 kHz? How about if the project was also using loops recorded at 44.1 kHz? If the Ardour project is at 48 kHz, the loops would need to be up-sampled, and then the whole thing down-sampled again to 44.1 on export. Would that up-down sampling offset any benefit of using 48 kHz in the first place? vic

[ANN] Mammut V0.60 and Snd-ls V0.9.8.1_beta

by Kjetil Svalastog Matheussen

Mammut 0.60 =========== Mammut will FFT your sound in one single gigantic analysis (no windows). These spectral data, where the development in time is incorporated in mysterious ways, may then be transformed by different algorithms prior to resynthesis. An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. *Homepage: http://www.notam02.no/arkiv/doc/mammut/ *Screenshot: http://www.notam02.no/arkiv/doc/mammut/mammut.png Changes 0.59 -> 0.60 -Updated source to work with Juce 1.44. (later or earlier versions of juce might not work with this version of mammut) -Fixed a couple of ugly bugs in the progress bar code. -Set moving camera to be off by default. Moving camera seems to stall mammut when using newer juce's. :-( Snd-ls v0.9.8.1_beta ==================== Snd-ls is a distribution of Bill Schottstaedt's sound editor SND. Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. (Its named beta, because it hasn't been tested that much. But I think it should work very well. However, a new non-beta version is going to be released quite soon with some additional fixes.) Changes 0.9.7.12 -> 0.9.8.1_beta -Fixed bug that caused snd to fail starting if no previously used soundfile was opened during startup. -Updated Snd from 8.4/12.9.2006 to 9.3/30.7.2007. Many important fixes. -Another attempt at fixing the rt_readin_tag startup bug. Download from http://www.notam02.no/arkiv/src/snd/
