QMidiCtl and QMidiNet (was Re: [PlanetCCRMA] Pd + PulseAudio?)
by Niels Mayer 25 Mar '10

25 Mar '10

Rui's note on qjackctl prompted me to look at http://www.rncbc.org and then http://www.rncbc.org/drupal/node/191 which lead to http://qmidictl.sourceforge.net/ and http://qmidinet.sourceforge.net/ ... Both of these apps look awesome. Any chance these can be made available through PlanetCCRMA or even better, through fedora which already carries up-to-date versions of qtractor. Also, one issue I've found w/ controllers in general is that there is a need for a simple scripting language, or a comprehensive set of "built-in special functions" to handle "state" and "computation" in midi controllers. Do qmidictl or qmidinet have any solutions for this? One quick example I ran into recently. I've setup a very useful remote control to a TC Electronics Finalizer. One of the features it has is a MIDI-controlled "fader" (e.g. for doing smooth fadeouts/fadeins). I've got that mapped to a 100MM slider on a behringer controller and it's SWEET. But also, it's linear. What I need is to map the midi controllers 0-127 to a logarithmic curve so as to match human loudness perception. This doesn't seem possible in qmidiroute... (?) What tools would allow this, or any other "computed" mapping to be done? (see also see http://old.nabble.com/using-qmidiroute-for-midi-device-control....-ts279631… ) Is there an easy way to add scripting languages to Qt apps? (something like 'Guile' would be nice). Niels http://nielsmayer.com PS: thanks to http://www.rncbc.org/drupal/node/183 , I will also be taking a look at qtractor-0.4.5-1.fc12.x86_64 which i've installed, but not yet explored ( rosegarden4-10.02.1-1.fc12.x86_64 works well for me so far).

One suggestion for using Jack as a replacement to pulseaudio was made here: http://pdavila.homelinux.org:8080/blog/?p=369 ... This comes up every once in a while in the jack* lists (and/or lac). So far no one (AFAIK) has gone beyond saying that it is the way it should be and that that would solve all problems. When somebody actually starts working the way down that path he/she will realize that it is not that simple (this is not to say that it should not be done or could not be done). Currently Jack2 (fc12+) plays nice with Pulseaudio and can get the sound card on startup and release it when exiting. And the Pulseaudio connection to Jack did work on limited tests I did. So you can start Jack, load the appropriate Pulseaudio plugin and redirect all PA streams to play through Jack. I experimented with that briefly when writing the perl script I used for Jack/PA interaction in fc11 when the PA vs. Jack interaction was still buggy. It was possible to start Jack and get an application that was playing on PA to keep playing transparently through Jack. So, the building blocks are already there, I think. Still, there are many reasons why it is not possible or desirable to make Jack a "system service" that starts when the computer boots. It is not designed to do that (security is one of the main problems). > Such an option would also make Fedora even more "the distro to have" > for doing prosumer and pro music and video on Linux, especially with > Fedora's strong support for infrastructure like qjackctl and patchage, > audio tools like rosegarden or ardour, and video tools including > qjadeo , kino, kdenlive etc. -- Fernando

Thanks Niels, Yes I admit I have not been so good with announcements of new update candidates. I will try harder. Best, Orcan

about Fedora updates
by Orcan Ogetbil 08 Mar '10

08 Mar '10

Hi folks, I just submitted rosegarden-10.02 to stable in Fedora since nobody yelled at me, and those who commented didn't complain. The main reason that I am writing is to ask you about your take on our update strategy in Fedora. Currently, there is a heated discussion in Fedora-devel mailing list about update policies. It might happen that our updates policy might change to a more conservative one. Are you happy with the current situation? What I do is, I typically push an update to updates-testing, leave it there for 2 weeks minimum (sometimes more). If no complaints, push it to stable updates repo. Do you think that we are pushing updates too frequently? I like to keep all of us up to date. We get a decently low number of bug reports. Do you have a stability problem with this policy? I can stop doing non-critical updates in stable Fedora releases if there is an issue. I just wanted to hear your opinion. Thanks, Orcan

fedora 12, Pulseaudio and Jack
by Jeff Sandys 08 Mar '10

08 Mar '10

In Fedora 12 with Planet CCRMA Jack Audio Connection Kit, does starting jack with qjackctl suspend pulseaudio? If not, how can I add pulseaudio suspend (and resume) to qjackctl? How can I tell if pulseaudio is running, is there a terminal command for pulseaudio status? I have searched through the jackaudio.org, pulseaudio.org, qjackctl.sourceforge.net and other sites, and didn't find an obvious answer. http://fedorasolved.org/Members/fenris02/pulseaudio-fixes-and-workaroundshas some info but not about jack. Thanks, Jeff Sandys
