[LAU] Audacity jack connections issue

Grammostola Rosea — 2008-10-07T08:56:03

Hi, A few months ago there was a discussion on this list about the management of jack connections in Audacity. It makes and close jack connections on play/stop, that should be on application startup and shutdown. Here you can vote for this jack improvement in Audacity: http://audacityteam.org/wiki/index.php?title=Feature_Requests#Playback_Enhancements thanks,

[LAU] Off-topic but related Opensource MIDI sequencer for Windows?

Tomas Valusek — 2008-10-06T06:58:30

Hello, I'm a blind music teacher and I'm looking for accessible MIDI sequencer. There are quite a few OSS sequencers on Linux, but AFAIK none for Windows. That'S why I'm writing this here - is anybody considering to port any MIDI sequencer to Windows? Both Qt and Gtk+ are present on Windows, so the only problem could be an underlying audio/midi infrastructure. I hope one day an accessible solution usable both by visually impaired AND people with good vision users. I'd like to use such a sequencer as an educational tool, and it should work both on Linux and Windows. Best regards. Tomas Valusek

[LAU] [ANN] Qtractor 0.2.2 (flirty ditz) is out!

Rui Nuno Capela — 2008-10-05T17:45:24

Qtractor 0.2.2 (flirty ditz) is out! ------------------------------------ Qtractor is an audio/MIDI multi-track sequencer application, written in C++ on top of Qt Software's Qt4 framework, having JACK and ALSA as its main infrastructures and Linux as native and exclusive platform. Specially suited to the lone-wolf composer, arranger and (re)creative music-maker personal home-studio, it still hopes to evolve as a fairly featured desktop audio/MIDI workstation or at least, a prototypal part of it ;) Release highlights: * Stephen Doonan joined documentation team and revised the user manual. * Spurious MIDI events recording bug ow fixed. * Audio track monitoring and plugin loop processing slightly improved if not fixed. * MIDI clip editor improved precision and correct snapping. * Multiple track mute and solo one-click toggling (NEW). * Better MIDI connection persistance across sessions. * Record-armed tracks aren't muted on playback anymore (NEW). * Optimized audio clip waveform caching and drawing. * Many m

[LAU] Sustainer 0.1 : a daemon to provide sustain pedal tosoftsynthsthat don't support it

Ken Restivo — 2008-10-05T05:56:45

Sustainer is a tiny ALSA MIDI daemon that provides sustain pedal functionality to softsynths that don't support the sustain pedal (such as PHASEX, AMS, Specimen, etc.). http://restivo.org/projects/sustainer/ I use the sustain pedal a lot in live performance for holding down pads while tweaking knobs or playing other parts (or both). It was annoying me that so many of my favorite softsynths for making pads, didn't support the sustain pedal though. I didn't feel like hacking all the softsynths that didn't have sustain pedal functionality, so I decided to solve it the Unix way by making a tiny utility to do what I wanted. I needed this to scratch my personal itch, and I'm publishing it so that others may enjoy it if they need something like this. I don't use JACK MIDI yet; I'm one of those luddites still on version 0.103 of JACK and refusing to take any risks on newer versions. But JACK MIDI is very straightforward, so at some point I'll convert this utility to native JACK MIDI. -ken

[LAU] Linux backing up Radioactive (of Spearhead)

Ken Restivo — 2008-10-05T02:08:15

Here's a clip of a Linux laptop working together with a real drummer, real conga player, and real guitar player to back up Michael Franti's rapper, Radioactive: http://www.restivo.org/blog/podpress_trac/web/398/0/audiobraille-radioactive.ogg Everything is improvised, including the rap, which is all freestyle. What stood out for me is what a great entertainer this guy Radioactive is! His primary gig is playing festivals with Spearhead, and it shows. As soon as Radioactive walked into the room and grabbed the mic, the energy level went up instantly, like a bomb had hit it. It was a very pronounced difference. The keyboard and bass sounds are Fluidsynth on Linux. Everything else is analog instruments and voice. The clip was recorded on a Zoom H2. I remastered it in JAMIN on Linux to bring out the vocals a bit more. -ken

[LAU] six channel output sound card recommendation

Jozef Henzl — 2008-10-03T09:26:20

Hello, i'm developing some software for company i'm working in, for playing back the recordings of a telephone calls, radio transmissions and stuff. The application obviously uses jack audio server and is running on a SuSE 10.3. Audio has to be played back to the six separate mono outputs, and i am searching for a sound card supported by a jack. The card should be PCI or USB. I don't need a hardware mix, and the sound quality can be low, as a recordings are did in a 4 or 8 kHz - no sound card can make the output worse i think :) I've found m-audio 2496 to be fairly reasonable, but i'm wondering if some of inputs can be configured as an output. thanks,

[LAU] update of jkmeter

Fons Adriaensen — 2008-10-02T21:46:55

Jkmeter-0.4.0 is now available at the usual place: Jkmeter is a combined RMS/digital peak meter based on the ideas of mastering guru Bob Katz. New options in this release: -type k14 : K14 scale instead of the default K20. Use this for mixing to a higher average level. -A : Ambisonic (4ch) mode. -C : Adds a stereo correlation meter. Used on a Ambisonic B-format signal the correlation meter uses W and X, and indicates how 'forward' the sound stage is. Enjoy ! Ciao,

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.

[LAU] Usage of undefinded MIDI mesages

Crypto — 2008-09-27T10:55:52

Hi, I have turned an old analogue electric organ into a MIDI controller. All the old push buttons, switches, pots, drawbars can now trigger MIDI events. Because I would like to make the MIDI messages static (i.e. they are linked with particular buttons and faders and will not be changed) I have thought of using an external application (keykit in this case) to work on incoming MIDI events of the MIDI controller, filter them and trigger newly defined MIDI events with it. I would like to make the MIDI messages transmitted by the controller as short as possible. I have thought of assigning the Bx (Control Change) command to the buttons and faders, but this would mix with/overwrite other control change commands sent by other MIDI devices. It has to be possible to distinguish between the buttons/faders by the MIDI message that each one triggers. How about the System Common Message F4 and F5 which are not yet defined in the MIDI standard? Could I add some extra data bytes to identify the type (button

[LAU] [ANN] bss - 0.5

Julien Claassen — 2008-09-26T23:45:45

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 regard

[LAU] ffado streaming mode

porl sheean — 2008-09-25T02:47:44

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

[LAU] Rosegarden crashes - anything obvious to look for?

Matthew Smith — 2008-09-23T10:34:14

Hi Folks Before I go through the painful process of collecting debug data and filing bugs against Rosegarden, I thought I'd see if anyone was familiar with the issues I am experiencing. Having finally got various external issues resolved, earlier today I attempted to record and play back a track on Rosegarden. I was using the current Gentoo ebuild, being the rather old version 1.5.1. I experienced a crash when trying to replay a track so upgraded to the latest masked ebuild, 1.7.2 - same issues. I have managed to get crashes when: 1) I attempt to play back a track. 2) I attempt to create a new track when there is a change to what is already there. So, I do 'new', I get 'the current file has been modified, do you want to save it?'. I say 'no', it crashes. When the crashes occur, I get a KDE crash handler pop up (I never even knew this was a KDE application) telling me that rosegardensequencer crashed and caused the signal 11 (SIGSEGV). After a short time, I also get a message from Rosegar

[LAU] Making ecasound stop when only one chain is done?

Ken Restivo — 2008-09-23T06:59:10

It looks like ecasound will continue processing until *all* the chains are done receiving input. Is there some way to get it to quit when only *one* chain is done? i.e., my little one-liner to use ecasound to feed JAMIN has a bug: it starts up perfectly at the start of the input file, but it sits there processing zeroes for as long as JAMIN is connected to the output chain. Not useful. -ken

[LAU] Batch-processing through JAMIN?

Ken Restivo — 2008-09-23T02:52:03

I am helping to (hopefully) produce a CD of one of the bands I'm in. The recording and mixing has been done on ProTools on a Mac, but it's been suggested that we "get it mastered". Before we spend money we don't have on some mastering house, I'd like to take the WAV files of the scratch mixes we have, feed them through Jamin, and see if the result is satisfactory. I'm certain I could write this, but I don't want to if it's already been done. So, is there a command line tool out there that will take a WAV file as an input, put JACK into freeswheeling mode, then jack_connect to a running Jamin instance's stereo in and out ports, open a WAV file for capturing the output, feed the input WAV file in to JAMIN and at the same time start capturing samples for the output WAV file, and thus basically feed this through JAMIN as fast as it can and give me a finished WAV file that's been "mastered"? I tried scripting this with jack_capture and mplayer, but there are two problems. The first problem is the mplayer starts
