[linux-audio-user] UA-100

by Malte Steiner

Hello, did anyone still have a Roland/Edirol UA-100 running under Linux? Its recognized as Alsa device and Jack also has it available but as soon as I started to use audio on it a heavy digital feedback built up, which sounds interesting but is artisticly pretty limited over a while. There are some OSS drivers and editor software but they fail for me to compile for a rather recent Kernel (2.6.12-686). Of course UA-100 runs fine under Windows XP on the same computer. I tried to run the editor for it with WINE but it can't see it. Thanks for any help, Malte -- Malte Steiner media art + development -www.block4.com-

[linux-audio-user] [ANNOUNCE] pdsend_3113 LADSPA plugin

by Orm Finnendahl

Hi, I just uploaded a pdsend LADSPA plugin on this page: http://icem-www.folkwang-hochschule.de/~finnendahl/pd.html It is called pdsend_3113 and it can be used for the remote control of fader automation in pd by ardour. That way, pd can be used for the development and prototyping of plugins or a LADSPA host like ardour can be used as a high resolution sequencer of control signals for pd patches. An example is included. -- Orm

[linux-audio-user] amd64 - distro questions...

by Piotr Pruszczak

Dear Sirs, I used to work with Debian (for 2 years as desktop) and I purchased amd64 3 weeks ago just to have top performance and possibility to use some dssi software / syntezathors etc... Just, I need some advise from Gentoo users - as I have to say, that I am just a little bit disappointed with poor *deb repositories, problems with dependencies and ... just I am thinking of "switch" by audio station to Gentoo (I love Debian for philisophy of GNU && independence and always will, however I WANT TO MAKE THE MUSIC ;) ) So, please AMD64 Gentoo guys, advise me - am I thinking right or not ? Also, how REALTIME LSM is working with Ingo Molnars patched kernel 2.6.14* / is DSSI working properly / maybe any Audio manuals for Gentoo ? and of course - I am interested in PURE64 architecture ;) -- Piotr

[linux-audio-user] puzzling ecasound error

by Paul Coccoli

ecasound is way too complicated for me. All I want to do is open jack stereo ins and outs, load the LADSPA amp_stereo plugin, and control that plugin's gain parameter via alsa midi. The -Md:alsaseq parameter is apparently ignored, and I get some error about a plate reverb?!

[linux-audio-user] LinuxSampler, dirty and unusable ( can't mlockall() memory!: Cannot allocate memory )

by Juan Marcelo Rodríguez

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, Im working with a korg controller via midi, through a SBLive 5.1 with some samples. I used to test qsynth, and works fine, even with big sound fonts files, now I got some interesting .gig files and I compiled linuxsampler with qsampler, and I got a dirty sound with all the .gig files, truly awful and unplayeable. I compiled the 'stable' and the 'unstable' software versions ( liblscp, libgig, linuxsampler, qsampler ) and from both I cannot work well with them. The output from the program, is the subject of the mail, the complete one ( sorry for the several lines ) is : ($:~)- linuxsampler LinuxSampler 0.3.3 Copyright (C) 2003, 2004 by Benno Senoner and Christian Schoenebeck Copyright (C) 2005 Christian Schoenebeck Detected features: MMX SSE Creating Sampler...OK Registered MIDI input drivers: ALSA Registered audio output drivers: ALSA,JACK Starting LSCP network server (0.0.0.0:8888)...Thread: WARNING, can't mlockall() memory!: Cannot allocate memory OK LinuxSampler initialization completed. :-) The warning is the same for both, stable and unstable.

[linux-audio-user] Which is the best way to simulate a real piano under gnu/Linux? Here's my proposal.

by Cesare Marilungo

So far I have a nice (but not impressive) soundfont downloaded here: http://www.hum.aau.dk/~bovbjerg/piano4.html I'm on a 64k isdn connection so I can't download and try every free sample on the net. While experimenting to achieve a more natural sound I tried dssi_convolve with some IRs downloaded from noisevault.com and got a nicer result. Now, I've just been inspired by the Florian Shmidth dssi_convolve entry on his blog and I decided to create an om patch with everything I need to have a realistic piano, with: - the samples already loaded when I open the patch (I think I can use fluidsynth-dssi, with a good soundfont); - the patch will send the notes to two different responses according to the state of the damper pedal (I'm not sure this could be done with om); - it would be great to simulate also the resonance of other notes when the damper pedal is pressed or other keys are already pressed; - it would be great also to simulate a true hammer action; I think it would be good for the community to have something similar or better than the Steinberg The Grand VSTi. What's your opinion? Can you help me? Or I am doing something that's already been done? In this case, where can I find it? Regards, c. - www.cesaremarilungo.com
