Timidity/Rosegarden issues
by A. A. 14 Dec '12

14 Dec '12

I'm not sure if this is the right place to send this. If there's a better place where I can get help, please tell me. I made a rosegarden project and exported it to a MIDI file. When I play this file with Timidity it sounds wrong- too much sustain on every single note. The original file still sounds fine on Rosegarden though. I wanted to check whether the problem is in the exporting or in the playing (in Rosegarden or in Timidity) by importing the MIDI file to Rosegarden, but now when I open QJackCtl it stops immediately after I press "start", so I can't play anything with Rosegarden. Another issue I had (when QJackCtl worked properly) was that Rosegarden constantly crashed every now and then. Can anyone help me? Here's the output from QJackCtl, in case it's relevant: 23:46:36.389 Patchbay deactivated. 23:46:36.390 Statistics reset. 23:46:36.392 ALSA connection change.

Thanks Agreed! I'll steal some of these things back into the Musicians' Guide when I get a chance... which should *actually* happen next week (gasp!) I would like to offer some simple suggestions for revision: 1.) Always use the same, correct name for everything. "JACK" is always "JACK" and never "jack" or "Jack." It's "D-Bus" not "DBus." It's "PulseAudio" not "pulse" or "Pulse" or "Pulse Audio" or "Pulseaudio" or "pulseaudio." This helps less experienced users and non-English readers know that you are always talking about the same thing. If I've never used Linux before, how am I supposed to know for sure that "DBus" and "D-Bus" (for example) are the same thing? 2.) Technical words should always be formatted distinctly: application/program names (like QJackCtl), system components (like JACK), filenames (like /etc/security/limits.conf), commands (like "ulimit -a"). On the Wiki, the Documentation Project's standard is that program names are italic, system components are bold, filenames and commands are fixed-width. 3.) Write like your audience is five years old. For one thing, they could be. More likely, especially as English speakers, we have to keep in mind that there are a lot of people whose first language is *not* English and who may only have the English skills of a five-year-old (however intelligent they may actually be). We want them to be able to use our documentation too, so we should make everything as simple as possible. This is by far the hardest part for me. As an example, consider the first sentence of "Integrate Jack [sic] with PulseAudio": "Jack will ask Pulse Audio through D-Bus for ownership of the sound card." I know exactly what that means, but consider it as though you were five. First question is "who is Jack?" Even if it were "JACK," this sentence treats some software as though it were a person. Software doesn't "ask" for things, and cannot "own" things. Plus, the "through D-Bus" part is a little awkward. I propose an alternative: "JACK uses D-Bus to gain control of the sound card from PulseAudio." It's still not great, but it's a little better. All of that being said, I appreciate your work here, and I obviously understand that the wiki is a place where things are *supposed to* start out rough and get polished up later. I especially like the level of detail you put here, as evidenced by the multiple options in the "Integrate..." section, and that you clearly intend to recommend DBus as the "best choice" when it eventually works. So keep at it! Further contributions on this or other topics would be greatly appreciated! Christopher

Frankly, I think we definitely don't need Scribus or especially Blender. GIMP and Inkscape are useful for modifying LilyPond output, and they're pretty small (Inkscape especially). I'm also willing to say we don't really need LaTeX because: 1.) I highly doubt there are a large number of people who aren't me but would still like to use Fedora Jam for writing academic music papers with LilyPond and LaTeX. 2.) Even I don't use the distribution-provided LaTeX because it's quite old. > > What is the default email client in KDE? > > kmail I'd imagine Yes, KMail and the Kontact suite. If default Fedora has a default of something, and "something" isn't an audio-specific thing, I feel we shouldn't change it. Let's waste our time on audio-specific things because, at the end of the day, nobody (reasonable) will avoid Fedora Jam *just because* we use the default Fedora browser instead of the default KDE browser.

ctrlr
by Martin Tarenskeen 06 Dec '12

06 Dec '12

Hi, has anyone succesfully tried ctrlr ( http://ctrlr.org ) on a Fedora system? The screenshots on the website look promising, but the provided Linux binary (I tried the 32bit version) crashes on my Fedora 17 system. I have not tried building from sources yet. Anyone? -- MT

Software that could be included in Fedora JAM
by <<<.F.G.P.>>> 06 Dec '12

06 Dec '12

Hello. I see that Fedora JAM is on the right path. I suggest some software that you could include if they seem useful. First and foremost, it is essential realtime kernel (Sorry I have not tried the kerenel that included, as I am running from a Virtualbox.) Azr3 (http://ll-plugins.nongnu.org/azr3/) Hammond emulator. Yoshimi (http://yoshimi.sourceforge.net/) Yoshimi is a software synthesizer for Linux based on the 2.4.0 release of ZynAddSubFX,. Spek (http://spek-project.org/) a simple and efficient spectrum analyzer. Sonic Visualiser (http://www.sonicvisualiser.org/) Sonic Visualiser is an application for viewing and analysing the contents of music audio files. DR14 T.meter ( http://dr14tmeter.scienceontheweb.net/index.php?title=Main_Page) a simple command line tool that compute the DR (dynamic range) of the audio files in your music collection. DISTRHO (http://distrho.sourceforge.net/ports.php) Audio plugins and Linux ports. Impro-Visor (http://www.cs.hmc.edu/~keller/jazz/improvisor/) is a music notation program designed to help jazz musicians compose and hear solos similar to ones that might be improvised. Triceratops (http://sourceforge.net/projects/triceratops/) LV2 Substractive Poly Synth QSampler (http://qsampler.sourceforge.net/qsampler-index.html) A LinuxSampler Qt GUI Interface (note: I'm not sure if it requires non-free software) Also you could include some banks such as sound of http://sonimusicae.free.fr/blanchet1-en.html. In any case, a download link for the ISO is not so big. Congratulations for your work and I look forward to the final version!

Probably take it to the mailing list first, esp. as it's Brendan and Jørn who are the official ks custodians. That said, some of the packages (such as realTimeConfigQuickScan) are F18 only, which is probably what's happening. Since it's targeting F18 release they probably wont change, it's technically possible to do what the official spins repo does and branch for releases but that might be too much overhead right now. -- imalone http://ibmalone.blogspot.co.uk
