Hi, I just discovered that linux journal covered rt-audio in one of their video tutorials. The guy compiles his own kernel and uses some stuff I haven't seen before, but all in all it doesn't look bad. Here's the link: http://www.linuxjournal.com/video/hyper-low-latency-audio-real-time-kernel And the direct link to the youtube video: http://www.youtube.com/v/zzvyV1hyDYc Maybe it's useful to someone. Best regards, Philipp

[LAU] [ANN] Virtual MIDI Piano Keyboard 0.2.0

by Pedro Lopez-Cabanillas

This release includes, among other features, enhanced mouse handling requested by Hermann Meyer, and a fix for the bug reported by Salvatore Di Pietro regarding MIDI channel numbering. Thank you very much for your feedback and comments! Virtual MIDI Piano Keyboard is a MIDI event generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player, with optional MIDI thru. Virtual MIDI Piano Keyboard is free software licensed under the terms of the GNU General Public License (GPL) v3. Changelog: 2008-09-26 0.2.0 New Features * RFE 2106023 MIDI thru * RFE 2106026 store connection names in settings * RFE 2106035 controllers state remembered * RFE 2106031 settings persistence: controllers/bank/program * RFE 2106015 translations (Qt Linguist) support * RFE 2107732 mouse handling enhanced: vkeybd behavior * RFE 2106021 custom highligh color * New icon/logo. Thanks to Theresa Knott * Spanish translation Fixed Bugs * bug 2116713 hide QJackCtl input port from connections * bug 2105246 start channel numbers from 1 instead of 0 * toolbars: workaround for an ugly Qt4.4 behavior when restoring the main window state.

[LAU] [ANN] bss - 0.5

by Julien Claassen

Hello everyone! You might have been wondering what I'm up to. So here we go. BSS is the "BBC7 Shell Script Suite" and package of a few shell scripts to search the bbc7 website via a simple commandline interface. You can also listen to the "listen again" service, by directly providing day and time. There's also a small audio-file converter. BBC7 is the BBC's station for comedy and drama. From the criminal, to the horrifying to the hilarious, to quiz-shows to readings of everyday and high literature. Please don't investigate the hidden bbc7-listen.sh option too much. They make their living from that and they offer a very nice service, which I hated to see going down. But of course it can occasionally be helpful to dump files to your disk. The link: http://juliencoder.de/bss-0.5.tar.bz2 Requirements: bash and the usual utilities for all of them, for the listen and convert scripts it's mplayer and ecasound and the search script requires wget. Hope you'll enjoy it! 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

2008/9/26 Brett McCoy <idragosani(a)gmail.com>: > How does it compare to Hydrogen? Can it *only* be used with CSound? Yes. It only can be used with Csound. Hydrogen is a great drummachine with it's own GUI. csDrummer is a simple console-based tool. It uses a MIDI file, created with any sequencer, like Rosegarden. It processes the MIDI messages and outputs an audio stream. There is one main feature which makes csDrummer better than Hydrogen: the morphing between two layers of sampled audio.

Rather it's a virtual drummer contolled by MIDI, playing at a complete drum set and recorded with virtual mics. It's a free analog of a commercial soft like a EZDrummer, BFD and etc. All samples are taken from one drum set, except toms. General MIDI map is not applicable here, because of drumset content. For example, there is 4 crashes and 2 chinas. GM precusion map has not any defined place for them. You can see them map used in csDrummer here: http://code.google.com/p/csdrummer/wiki/Drumset. Some of the instruments use GM map, but others do not. This drumset is suited for Rock, Punk, Metal and so on. This is a cause of why other samples are missing. Maybe I'll create a few thematic kits for different styles later.

[LAU] ffado streaming mode

by porl sheean

a while ago i purchased a focusrite saffire pro 26io. it has finally come to a point where it is quite reliably useful as an interface for jack/ardour (the latency isn't brilliant, but i'm pretty sure that is the fault of my firewire chipset). i found out recently that unfortunately, in order to get teh device working as a basic 'summing mixer' for live work (i wanted to essentially use it as a basic 8 in 1 out preamp to send to a small desk at a venue) it needs to be set in 'streaming mode'. i can get this working by starting jack and just leaving that running, but i was wondering if anyone knew of an easier way (maybe one of ffado's command line utilities? there seem to be a lot in there and i don't know what half of them do). if not, would it be difficult to write a small app that basically just 'turns on streaming'? or should i just keep using jack? (i am hesitant to do this as i have still had a few issues with dropouts, and as you can imagine at a live performance this could be a problem). thanks for any advice porl
