Looking for people in Heidelberg/Mannheim-Germany

by Gerald Mwangi

Hi, The subject says it all. I'm wondering if there are some musicians living in the rhein-neckar area in Germany, who would be interested in my Band www.jimson-drift.de (also check https://www.jamendo.com/de/list/a62900/groove-venture ). We play a mix of rock/soul and Funk and are in the process of integrating Electronica elements in our songs (not yet in the current demos). Our Drummer decided to leave the Band by the end of the year and our Bassist will probably go next year due to their jobs. I'm looking for people who want to break with the old styles by mixing them together to something new, experimental but still mainstreamy enough to get the audience moving with the groove. I'm looking for people who would drop everything else, if we had the chance to go to the top (charts, big stadium, fun) without being bent to conformity. Who's in? Lg Gerald

Update to "Robust Session Management"

by Jonathan E. Brickman

A major rewrite; quite a lot faster and better now, was needed for an enormous patch in the works: http://lsn.ponderworthy.com/doku.php/robust_session_management Now using Python scripts for process management, a separate hand-off method for patch changes, and other improvements. -- Jonathan E.

Ardour: Recorded regions in one track to individual tracks

by Carlos sanchiavedraz

Hello dear all. Some time ago, maybe years because I think it was Ardour2 at that time, somebody asked if anyone knew a non-manual-tidious way to have all the playlists of one track in Ardour converted to individual tracks. This was to be able to Solo/Mute each take to filter the best ones instead of constantly changing playlists. Well, I would like to refresh that question (for Ardour2 and Ardour3 now) and ask more or less the same again but for individual segments in a track that were recorded on a tracking session. The reason why this segments are all in the same track is that they were recorded by the same person who was playing and at that moment it was quicker to do like that instead of having to deal with playlists in every recording track or several new tracks one for each take and source recorded. I guess there are many DIY musicians that have experienced this and maybe come to a solution, or maybe there's some functionality in Ardour I'm not aware of. Thanks in advance as always. Regards. -- C. sanchiavedraZ: * NEW / NUEVO: www.sanchiavedraZ.com * Musix GNU+Linux: www.musix.es

Sound Devices - USBPRE 2 - Status ?

by OvO OvO

Hello everyone. Looking for a external sound card with good preamp to record. Found the Sound Devices USBPRE 2 suits my need. Browsing the web, the Sound Devices web site and this list, it seems to be supported for UAC1 with no trouble but only with 48khz. The message is now old : http://linuxaudio.org/mailarchive/lau/2013/1/25/196179 Anyone can give some update about the UAC2 status with Alsa on this card ? Please. ps: running a Gnu/Debian Stable. Best.

ALSA resampling

by Ken Restivo

Being lazy here, so quick question: I'm looking for a simple way to resample in ALSA from a capture/play interface that supports only 48kHz, to 44.1kHz which is desired. Both playback and capture resampling is needed, and it seems I neeed dsnoop and dmix. However, I am bewildered by the somewhat byzantine configuration of .asoundrc. There's one card on this machine, a "SB LIVE!" (which means "48kHz only!"), running the emu10k driver. There's no JACK up in this at all, it's just an old streaming PC running BUTT. There is also no PulseAudio because I avoid PulseAudio. If I were using ices2 I suppose I could use its built-in resampling, but that's not an option in this case. -ken

Lightweight WM that can be used without any issue with audio applications

by Ralf Mardorf

I switched from Xfce4 to JWM. JWM does work with all apps excepted of QjackCtl. Often I need to kill QjackCtl, because the Connect window always is above all other windows and it's impossible to close it. I don't want to use a tiling window manager or a WM that is nearly as bloated, as DEs such as Xfce4. What WMs do you use? A lightweight DE would be ok too, as long as it isn't unstable and has got no dependencies to GNOME software. Bad coded stuff like Enlightenment is a complete no-go. I want to handle windows with the mouse, they should be free to overlap and I don't want to experience issues, even not issues that happens seldom, workspaces should be editable. JWM is nearly perfect, excepted of the QjackCTL issue.

another cpu question

by Ede Wolf

Hello all, I may be putting together a box dedicated just to act as a multitrack effects unit - without planning any recording. The effects stack will for most channels most likely look like this: reverb, delay, EQ and maybe one of flanger, chorus or rather seldomly compression. Anyway, just the classics, planning so far to only to install the calf and invada lv2 packages. Though I am open for recommendations here, too. And of course I am looking for a suitable effects host/rack. However, I do suppose, the reverb will be the most cpu consuming item and I am wondering, what feature an a cpu should I be primarily looking for? I guess, for effects, especially reverb, the floating point performance will be paramount? As HT generally has a bad reputation for audio, currently, the AMD FX-8350 is on top of my list, as the floating point preformance is said to be rather good and lots of cores should be ideal for running lots of effects in parallel - though unfortunately not every core does have its on FPU. As it is not going to run 24/7, the insane energy consumption is somewhat acceptable. But, beeing no coder, I may be completely off track with my conceptions here, so I am asking for some more insight or alternative recommendations, maybe even with a short reasoning Thanks Ede

Smoothing congas

by jonetsu＠teksavvy.com

Hi, Congas (in this case Wavedrum congas # 19) have sometimes hits louder than others. Eg. the player hits more forcefully at times. What would be a good way to even out the output (recorded in Ardour) so that the stronger hits do not stand out as much in the mix ? Cheers.

Each program, opensource or not, has its own system and ne'er the 'twain do meet. So one restricts to one program, no other choice. Microsoft is so big so makes its own standards, its own rules, changes them at will (example rtf), but they are not in the DAW business. Just many programs run on their platform so may use some of their file-structures. What if the programs we use here, on this list, were inter-operable? Ardour/Harrison, Qtractor, Muse, Rosegarden, etc. We have more choices than does Microsoft. What if Tracktion (proprietary, now supporting Linux!) were brought on board? I do not think it is so far-fetched if there be a will to do so. One opensource library to service this, done once. (I no longer have my old posts, proposals for this. Discussion was a while back.)
