I was wondering what a really good software reverb was for Linux? I am using QSampler and would like to have some reverb for the instruments? Thanks.

In theory the accuracy bar and the coloured notes should work without any changes to Piano Booster in "Play Along" mode. I have posted this linux-audio-user mailing list as well in case anybody else wants to test this out as well. Thanks L o u i s Piano Booster is available at: http://pianobooster.sourceforge.net

hydrogen drumkits to soundfont

by Nathanael Anderson

anyone have a script that will turn hydrogen drumkits into soundfonts? i like making my drum loops in hydrogen, and exporting as midi, to embed in compositions, but i'd like to be able to use hydrogens kits, as opposed to a generic soundfont. Nathanael

LinuxSampler - Status?

by Julien Claassen

Hello LS-guys! I've just wondered about LinuxSampler and the accompanying libraries. I just went over to linuxsampler.org, but didn't find anything new in the ChangeLog. So what's the latest progress? Has work been done considering the IR and jconv-code integration. I remember some talk about it some time ago. I'd be glad for some info. - Meanwhile keep up the good work and thanks for the work done so far! 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

disabled onboard soundcard - uninstall drivers?

by Ludo Beckers

(Ubuntu Hardy) Having problems with my new soundcard Audigy (Creative Soundblaster) with recording through the microphone. Playback for .wav, ogg, etc. works good. I can't record in Sound Recorder nore Audacity nore use it with Skype. The Volume Control is a mystery to me because there are too many strange meaningless names (LFE and "front end" and much more). I disabled the onboard soundcard in the BIOS, but read something on Google about disabling the drivers for it too might be a good idea. How do I find which and where those drivers are? and does it make a difference uninstalling them?

Sorry for my poor knoledges, but, it means that all, audio and midi event pass trough the ethernet cable ? If I understand I use my computer normally, but I do not use my sound card, I use the network. And my friend will receive all the midi and sounds, and route them through his sound card ? 5.8 and 2.9ms are very exiting ! Is there any complete documentations on the net ? What are your jack settings ? I imagine there are some network settings too ? Thank you for your answer. cheers, Mysth-R -- * *************************************************************************************** * {^_^} Mysth-R {^_^} * <= Aide Auditive => * * http://myspace.com/mysthr * http://myspace.com/aideauditive * http://mysthr.free.fr/Joomla => Site dédié à l'audio sous Fedora/PlanetCCRMA. * ***************************************************************************************

[ANN] Songs 0.4pre1 and some help on equalizer

by Cedric Roux

Hi everyone, here is a pre-release of songs 0.4: http://sed.free.fr/songs/songs-0.4pre1.tar.gz (pre1 because I will use it to record some stuff and do a release after that, to catch some bugs) There is a reverb (order 15 CFDN, coming from sverb, but some parameters may not be that good, so the quality is far from perfect for an order 15 CFDN I guess). There is an equalizer (kind of "programmable eq," ie. you write some code and the equalizer's parameters are generated). I am not satisfied with the equalizer (it's a FIR designed with basic window method). So I need some help. What kind of equalizer do you use (like "10 band graphic eq" or "parametric eq") (and with which software, possibly free so I can read the source)? If you are good at DSP, I would like to generate an IIR filter out of my input (an arbitrary frequency response coming from some user's instructions) instead of a FIR. Any technique/pointer to some documentation/code? Thanks, Cedric.

[ANN] [alsa_midi_plumber] Maintain midi connections, jack.plumbing style.

by Miguel Morales

Hi all! I was always looking for a way to maintain my midi connections the same way I maintain my JACK connections using midi.plumbing. Nothing that I found satisfied my needs so I cooked up this dirty little script. Basically it just parses the output of aconnect and maintains the midi connections using a rules file specified by the user. Anyway, it's a really simple perl script, here's the link: http://diastrofunk.com/alsa_midi_plumber.html http://www.freewebs.com/bh_x/alsa_midi_plumber.html Enjoi! -- The Revolting X Software/Music Production: http://diastrofunk.com
