Fwd: [linux-audio-user] Free-as-in-freedom B3, other than Bristol?

by Petter Sundlöf

azr3 ported to lv2 by Lars Luthman is the best choice. it requires LV2 and JACK MIDI. sure, it's a bit of a pain to set up, but it's definitely worth it. http://ll-plugins.nongnu.org/azr3.html 2007/3/20, Ken Restivo <ken(a)restivo.org>: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Is there such a thing as a free-as-in-freedom alternative (no matter how paltry) to the Native Instruments "B4"? > > I tried Bristol and... it looks gorgeous but IMHO sounds way too thin and cheezy. > > There seem to be dozens of soundfonts out there with B3 sounds, but the ones I've tried so far aren't very good.

[linux-audio-user] ANNOUNCE: Sonic Visualiser and Vamp plugin SDK 1.0pre3 released

by Chris Cannam

Announcing the release of Sonic Visualiser 1.0pre3, a pre-release for the soon forthcoming Sonic Visualiser 1.0. http://www.sonicvisualiser.org/ Sonic Visualiser is an application for viewing and analysing the contents of music audio files. It contains advanced waveform and spectrogram viewers, as well as editors for many sorts of audio annotations. Besides visualisation, it can make and play selections based on the locations of automatically detected features, seamlessly loop playback of single or multiple noncontiguous regions, synthesise annotations for playback, and time-stretch playback while retaining display synchronisation. Sonic Visualiser also makes use of the Vamp plugin API, for plugins that extract descriptive or analytical data from audio. Vamp is an easy to use plugin API with a comprehensive and well-commented SDK, and is now frozen for the Vamp 1.0 release. Sonic Visualiser is Free Software distributed under the GNU General Public License. The 0.9 release is available now in source code form or as binaries for Linux, OS/X, and Windows. For more information and downloads, please see http://www.sonicvisualiser.org/ For more information about Vamp plugins, please see http://www.sonicvisualiser.org/vamp.html See also the SourceForge page for this project at http://www.sourceforge.net/projects/sv1/ Sonic Visualiser was developed at the Centre for Digital Music, Queen Mary, University of London and partially funded by the European Commission through the SIMAC project IST-FP6-507142 and the EASAIER project IST-FP6-033902.

[linux-audio-user] Qsynth multi audio channel config problem

by ciwe＠gmx.de

Hello everybody, I've tried to set up qsynth with multiple audio output channels for each midi channel. Is it possible? Below is the ~/.qt/qsynthrc file of my tests where I set multi jack outputs to true, 16 audio channels and one audio group (tried also 16 audio groups). So what I'm doing wrong?

[linux-audio-user] If all else fails, try emigmatic :)

by Folderol

I guess this won't appeal to a lot of you but for those who like their music soft and squidgy: http://www/musically.me.uk/music/For_Girls_Meadows_And_Unicorns.ogg http://www/musically.me.uk/music/For_Girls_Meadows_And_Unicorns.ogg A theme tune for all those stories about the above. This is another 'live play' transferred to Rosegarden + ZynAddSubFX then tarted up a bit and extra accompaniment added for depth. -- Will J G

[linux-audio-user] Squeezing any more performance out of this old laptop...

by Spencer Russell

With all this talk about laptops, I was wondering if there's anything I can do to make mine usable. My main audio computer has been on the fritz recently, so I'd like to be able to work with my laptop while I'm troubleshooting. The problem is that the best latency I can get is 2x1024 frames, which comes out to 42.7 ms at 48000 Hz. This is clearly not usable for live processing work. The laptop is a couple years old, and has a 1GHz AMD Duron processor and 256MB of RAM. I've got a 2.6.20 kernel patched with ingo's RT patch, set to full preemption, and with all power management disabled. I'm using Debian's most recent PAM package to give my regular user realtime privileges and the following in my limits.conf: @audio - rtprio 99 @audio - memlock 100000 @audio - nice -10 Jackd doesn't complain about not being able to get realtime, so I think that's working. Also, when I use chrt to look at the priorities of the jackd threads, there are 2 of them running SCHED_FIFO with priorities of 20 and 10. /proc/interrupts tells me that VIA686A (my onboard chipset) is the only thing on IRQ10, and chrt tells me that IRQ10 is running SCHED_FIFO at priority 50, as are all the other IRQ threads. Boosting the priority to 60 doesn't seem to make a difference. Is there anything more I can do? Thanks, spencer

[linux-audio-user] Kqemu module and realtime, rt-patches

by David Baron

Is there any conflicts here? Keep getting failure to open existing /dev/kqemu (regardless of permissions) with an rt-patched (Ingo) kernel.
