But with so few bugreports it's difficult to fix. (unless there's some > LADSPA/swh list I've missed?) Hey, that's the truth ;) I have got some valuable bug reports from Nick, but I've yet to fix the problems, thier deep and tedious to fix sadly. I have been doing a fair bit of plugin hacking recently, I'l make a new relaese when I've fixed the problem Nick found (flanger IIRC). Theres done seem to be some SSE2/gcc3 wierdness going on too, I saw a mention of some related sounding problems in an article somewhere, but I forgot what the problem they'd found was. I have been considering a mailing list so I can get consensus on bug reports, if there are enough interested people I'l set one up. Another idea (suggested by Dave Phillips) is setitng up a web page where people can make comments agianst the docs or something, but that involves me writing the web stuff, Its a great idea but frankly I'd rather put my efforts into writing plugins. I will get round to it if there aren't enough people for a list though. - Steve

Unfortunately Audacity 1.1.3 doesn't seem to scale well beyond four input channels on our machine. Does tkeca have native ALSA support, or does it use OSS emulation only? Thanks Daniel

[linux-audio-user] noteedit-2.1.2(ritardando, pedal marks)

by Joerg Anders

Version 2.1.2 of the cost free musical score editor NoteEdit is available: http://rnvs.informatik.tu-chemnitz.de/~jan/noteedit/noteedit.html New features: - ritardando - accelerando o to create a audible ritardando (accelerando) simply place the ritardando (accelerando) between two different tempo signatures. NoteEdit assumes the ritardando (accelerando) begins at left tempo signature and ends at right tempo signature - piano pedal marks o TiMidity++ users! NoteEdit uses the MIDI PEDAL COMMANDS to play the pedal on/off signs. Unfortunately, TiMidity++ treats these commands wrong. Therefore, if you are a TiMidity++ user, it is recommended to avoid the MIDI PEDAL COMMANDS during replay (see "configuration section"). Unfortunately, the pedal on/off signs have no effect in this case :-( -- J.Anders, Chemnitz, GERMANY (ja(a)informatik.tu-chemnitz.de)

May sound an odd question but IIRC there's something in the (lengthy and pretty good) documentation for the version I installed some while back that suggests you'll run into memory problems unless it's closed with Ctrl+Q. Sorry if this is a little vague, but it may provide a pointer.

[linux-audio-user] Getting USB Audio Quattro to work

by Denis de Leeuw Duarte

Hello! Somebody told me a few of you have managed to get M-Audio's USB Audio Quattro to work. I'd like to join your ranks, but I'm having a small problem. By the looks of things the USB settings are all correct and the ALSA (0.9.3) kernel module loads like it should, but the alsasound script gives me a peculiar message: Starting sound driver: snd-usb-audio done No state is present for card tm It then automatically writes a new asound.state file containing only this: state.tm{ } I don't know if this is good or bad or unimportant, but nonetheless, I don't hear anything when playing back sounds. I found the .asoundrc file for the Quattro by Patrick Shirkey somewhere and I saved it to my own .asoundrc. Here is what some of the aplay commands output: This actually _looks_ good, but I can't hear sound: denis@denlap denis $ aplay /usr/kde/3.1/share/sounds/pop.wav Playing WAVE '/usr/kde/3.1/share/sounds/pop.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono Here I tried to use the device names from the asoundrc file, but then I get an error: denis@denlap denis $ aplay -D quattro1 /usr/kde/3.1/share/sounds/pop.wav Playing WAVE '/usr/kde/3.1/share/sounds/pop.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono aplay: set_params:810: Channels count non available So, my question is, what am I doing wrong? Did I take all the necessary steps? Is there a way do get more diagnostics? I hope you can answer my questions, because this thing is pretty expensive for a paperweight ;-) Regards, Denis p.s. if you need more info, let me know. Just to be on the safe side, here's a few of my files. Note that the device is named 'tm' which is (i think) because of the (tm) in the descriptor. I really don't know how all of this wors though, so educate me please.

Hello Sweep users, Conrad is looking for help with testing the new ALSA 0.9x support in version 0.82. You have to enable ALSA support at ./configure time.

[linux-audio-user] Re: tkeca recording more than four channels?

by Daniel James

> These four channels in Recording Properties mean a quadraphonic > audio file (not too common). The usual is 1 or 2 (stereo) channels > files. Thanks for the quick reply! We're using an M Audio Delta 1010 which has eight analogue simultaneous inputs and outputs. We're trying to record a four piece band live, so that each player has an independent stereo track. After that, we can overdub with more takes to give us 16 tracks and more. We are using ALSA 0.92 and the envy24control mixer/router, and it's working really well with Audacity with up to four input channels. The multichannel support in Audacity is experimental, and so far it isn't scaling well (on our system) to eight inputs. We wanted to try another multitracker for Linux to find out where the problem lies - so we thought of the venerable ecasound. tkeca looked like it could be a great front-end for this job, because it looks to be very light on resources. Cheers Daniel

[linux-audio-user] tkeca recording more than four channels?

by Daniel James

Hi Luis, Is it possible to record more than four channels per track with tkeca, and have the sound in each channel remain as an independent files? In the recording properties dialog, I can only see up to four channels available, but is there another way of doing this? Thanks for creating it! Daniel
