But when having many many clients with lots of connections, it gets quite complicated. It would be nicer with a more loose patchbay type of pd/jmax/alsamodularsynth/etc. --

I am thinking there should be different representation of the graph, that you can switch between. Two ideas I have been thinking of: 1) A matrix like connection view, rows are output-ports, collums are input-ports Very useful when you look at it port-centrically. You see all the connections of a single port at once. 2)Some kind of graph layout algorithm. More like pd, but maybe the connections on the side. Useful for looking at the signal path through multiple modules/jack-clients. There are some OS libraries/apps and a lot of literature for this. But I think most of it is too heavy for a patchbay. A complicated jack-graph is _very_ simple for program meant for 1000+vertex graph layout. Luke Yelavich wrote: > There already is. Check out http://qjackctl.sourceforge.net. > That is not what is being discussed though. The patch-representation model of qjackctl is pretty much useless (unreadable) for anything beyond connecting an application to the pcm. Although it _is_ a great app, it is a bad patchbay gui. I regularly use a session with: 10 channel pcm, 8 channels fluidsynth 2 channels hydrogen drum machine 16 channels ardour 2 channels rosegarden (only used for sequencing, but it still connects it self) When I finished routing, I see a blur between input and output ports in qjackctl.

[linux-audio-dev] Tascam US-122

by Klaus Bickert

Recently bought a Tascam US-122 interface (24bit/96khz 2 in/2out w mic phantom preamp, 2 midi, phones, direct monitoring). Works great on Megascrap. Found a hint on US-428 driver supporting it but doesnt work on a Suse 8.2 (Kernel 2.4.20), seems to lack other parts of module stack, cant identify. Suggestions anyone, please ? Ciao, ufo <kfb(a)mpe.mpg.de>.

[linux-audio-dev] ANNOUNCE: JAMin [0.8.0] first JACK Audio Mastering interface release

by Jack O'Quin

The first stable release (0.8.0) of JAMin - the JACK Audio Mastering interface is now available for download. JAMin is a GPL licenced, state-of-the-art realtime mastering processor designed to bring out the detail in recorded music and provide the final layer of polish. Every effort has been made to ensure a clean, distortion-free signal path. All processing elements use linear-phase filtering, ensuring that no phase distortion is introduced. JAMin runs on Linux using the JACK Audio Connection Kit, a low-latency audio server, which can connect a number of different applications to an audio device, and also allow them to share audio among themselves.

[linux-audio-dev] ANNOUNCE: Rosegarden-4-0.9.6 released

by Chris Cannam

The Rosegarden team announce the release of Rosegarden-4 0.9.6, an audio and MIDI sequencer and score editor for Linux. To download the source package, go to the homepage at http://www.rosegardenmusic.com/ This release is primarily to address a significant problem with 0.9.5 that was seriously affecting sequencer timing performance for some users. For this reason we strongly recommend an upgrade. Be aware that one of the fixes in this release mandates the use of Qt 3.1 or newer to build; Qt 3.0 is no longer supported. This release also contains new translations of the GUI into Italian, Swedish and Estonian, thanks to Daniele Medri, Stefan Asserhäll, and Hasso Tepper. These are in addition to the existing support for US and UK English, Russian, Spanish, German, French, and Welsh. Chris

[linux-audio-dev] rt irqs patch to 2.4.23

by Kai Vehmanen

Hello all, here's a new approach to improving kernel RT performance. This specifically tries to improve interrupt latencies, so it's complementary to the existing preempt and lowlatency patches. # linuxdevices.com article http://www.linuxdevices.com/news/NS3235024671.html ""Metrowerks Senior Software Engineer and veteran real-time programmer Bernhard Kuhn has created a Linux kernel patch that he claims enables hard, real-time performance in the Linux kernel by adding priorities to interrupts and spinlocks. Kuhn believes his approach to be more "natural" and akin to traditional real-time operating systems (RTOSs) than the dual-kernel approach taken by real-time projects such as RTAI and RTLinux, and he is hopeful that his patch might one day win enough interest and support to become part of the official Linux kernel tree."" # Kuhn's post to linux-kernel http://www.ussg.iu.edu/hypermail/linux/kernel/0401.1/0300.html # Kuhn's announcement http://linuxdevices.com/articles/AT6105045931.html # patch against 2.4.23 http://home.t-online.de/home/Bernhard_Kuhn/rtirq/20040108/rtirq-20040108.tgz -- http://www.eca.cx Audio software for Linux!

[linux-audio-dev] programming time signature and tempo

by James W. Morris

Hello everyone, I've recently started updating wav composer not toilet (wcnt.sourceforge.net) the humourously named, rarely used, not-real-time audio sequencing, sampling, synthesis wav file generator. can anyone point me to some information about time signatures and tempo which would be useful from a programmers perspective. I've looked on the internet and what I found either told me nothing I did not know or just said that time signature was irrelevant (ie for notation only) and it was down to the performers to decide. so far my code is based on 4/4 (4 'beats' of quarter notes per bar/measure). a single bar has a value of 256, with halfnote 128, etc. What I need to work out is how a different time signature will effect this, would I need to change the value of a bar etc? I tried some experiments in cubase (i've not got any realtime sequencers working in linux yet) with audio blocks snapped to every half bar. What confused me completely was when I changed the time signature to 5/8. the snaps to half bars stayed in the same place, but the snaps to bars changed, ending with every 5th block snapped to a half note actually landing on a bar. Uh? can any one shed any light ? thanks in advance, James Morris. ~(sirromseventyfive)~ _________________________________________________________________ Find a cheaper internet access deal - choose one to suit you. http://www.msn.co.uk/internetaccess

[linux-audio-dev] Q 4.6 released

by Dr.Graef＠t-online.de

Q is a multi-platform functional programming language based on term rewriting, which comes with a collection of useful addon modules for system, scientific and multimedia programming. Release 4.6 of Q is now available, along with Q-Audio 1.2 and Q-Midi 1.12. Q 4.6 provides a much improved GGI module and a new ImageMagick module, both very useful for programming graphics in Q. Q-Audio 1.2 features a new module to display audio data in a GGI visual and a sample graphical audio player application. Q-Midi 1.12 sports some minor fixes and a simplified Windows install procedure. Downloads and more information about the Q project can be found on the Q website at http://q-lang.sourceforge.net Enjoy! -- Dr. Albert Gr"af Email: Dr.Graef(a)t-online.de, ag(a)muwiinfa.geschichte.uni-mainz.de WWW: http://www.musikwissenschaft.uni-mainz.de/~ag
