Hi, QMidiArp 0.5.2 has just seen the light of the day. It brings mainly two improvements. One is a comeback, that of tempo changes on the fly, and that now includes also tempo changes of a potential Jack Transport master. Also the Jack Transport starting position is finally taken into account, so that QMidiArp should be in sync also when starting the transport master not at zero. The second one is Non Session Manager support, mainly thanks to the work done by Roy Vegard Ovesen! Note that for compiling in NSM support you will now need liblo as dependency. Enjoy, and enjoy LAC in Graz this year Frank ________________________________ QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO. Everything is on http://qmidiarp.sourceforge.net qmidiarp-0.5.2 (2013-05-09) New Features o Tempo changes are again possible while running, both manually or by a Jack Transport Master o Jack Transport position is now taken into account when starting, QMidiArp used to start always at zero o Muting and sequencer parameter changes can be deferred to pattern end using a new toolbutton o Modules in the Global Storage window have mute/defer buttons o Global Storage location switches can be set to affect only the pattern o Non Session Manager support with "switch" capability (thanks to Roy Vegard Ovesen) General Changes o NSM support requires liblo development headers (liblo-dev package)

[paul@linuxaudiosystems.com: [Jack-Devel] jackaudio.org website shut down due to hacking]

by Adrian Knoth

Hi! I'm sure there must be users out there who are familiar with web stuff and are burning to help their favourite inter-application audio framework. ;) Step up, please. PS: There is also a semi-complete move to GH-pages. If your're familiar with github, you could be the ideal volunteer. ;) Cheers ----- Forwarded message from Paul Davis <paul(a)linuxaudiosystems.com> ----- Date: Fri, 30 May 2014 11:56:02 -0400 From: Paul Davis <paul(a)linuxaudiosystems.com> To: JACK <jack-devel(a)lists.jackaudio.org> Subject: [Jack-Devel] jackaudio.org website shut down due to hacking The malicious conscience-free leeches who push pharmaceutical spam managed to hack into jackaudio.org in a very deep way. They had full access to everything including the ability to fiddle with MySQL tables (some of them). I don't consider any part of the Drupal site safe, so I have shut it down and replaced it with a single static index.html file. The source tarballs for JACK1 were uncorrupted (probably JACK2 also - waiting for confirmation from Stephane on this), and I have put up a new link to the most recent. I also referenced github for the source code repository and issue tracker. As someone said on IRC today " It's a shame the lead dev has to waste his time coding, answering user questions AND fixing drupal backdoors " If someone else wants to volunteer to resurrect the roughly 60 pages of content that were at jackaudio.org (and realistically, it is probably more like 20 of real stuff that is needed), get in touch. I can give you full access to everything you will need. _______________________________________________ Jack-Devel mailing list Jack-Devel(a)lists.jackaudio.org http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org ----- End forwarded message ----- -- mail: adi(a)thur.de http://adi.thur.de PGP/GPG: key via keyserver

New MOD Website

by Gianfranco Ceccolini

Hi everybody Still recovering from the LAC2014 trip but already with news, here’s the link to our new website (including english version) www.portalmod.com The video that was shown at the MOD presentation is right in the frontpage. Even better, the plugin library can now be navigated in the same way as in the MODs interface. On top of it, there’s a dashboard section where visitors can try the interface without audio. Hope you all enjoy. Cheers Gianfranco Ceccolini

Openframeworks

by Bart Brouns

Hi list, I just discovered openframeworks http://www.openframeworks.cc/ And it almost looks too good to be true. For example, have you seen this?: http://vimeo.com/59653952 Why is ofx not so prolific in lad land? I searched the lad mailing list and found just a handful of mentions over the years. Who's using it? Can you recommend it? Would you have used it if it was available at the start of your project? Best, Bart. studio magnetophon Bart Brouns Biesenwal 3 6211 GZ Maastricht 0031-6-22919561 bart(a)magnetophon.nl www.magnetophon.nl

Ring buffers again

by Will Godfrey

As well as the jack ring buffer, I've looked at several others now, and their example code. The most significant thing that seems to be different about them (from a usage point of view) is the way they handle overflows. However, if the buffer size is defined as an exact multiple of the data type/structure and only complete structures are pushed or popped, would I be right in thinking that you would only need to check on an all/none basis? Have I missed something that could cause a partial data transfer? -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Re: [LAD] Call for testing (final): ALSA driver for some firewire devices

by Takashi Sakamoto

Hi Daniel, I notice that I cannot help you without enough logs with which I can realize what happens. At lease, 'verbose' options for aplay/arecord, '#' nodes in /proc/asound/cardX and dmesg. Additionally, would you please add 'LANG=C' when you get output from software. I cannot read Spanish language... > hi, it does not work. Try in following steps: 1. $ arecord /tmp/test.wav -D hw:UFX1604 -c 16 (I expected you receive 'Available formats' output) 2. $ arecord /tmp/test.wav -D hw:UFX1604 -c 16 -f (here the format, maybe S32_LE) (I expected you receive 'rate is not accurate' output) 3. $ arecord /tmp/test.wav -D hw:UFX1604 -c 16 -f (the same above) -r (got rate) (I expected it will run correctly.) I hope you to do these test when killing pulseaudio. The way is here: https://wiki.ubuntu.com/PulseAudio/Log Regards Takashi Sakamoto o-takashi(a)sakamocchi.jp

Re: [LAD] open ALSA device

by Martin Lohberger

i already have a ladspa-plugin that process my audio data. this works fine without any problems. Due to an adaption of the functionality of my system, i want to add a function that determines if the system works properly. This function should send an audio signal, that is recorded afterwards. And this should also work while no application (aplay, skype etc.) uses alsa. Due to this I want to know if it's possible to use a plugin or an other virtual device that "keeps the floor". 2014-05-20 12:59 GMT+02:00 Martin Lohberger <elektm.alsa(a)gmail.com>: > i already have a ladspa-plugin that process my audio data. this works fine > without any problems. > Due to an adaption of the functionality of my system, i want to add a > function that determines if the system works properly.
