[07:18] <contrapunctus> Good day, mateys. Anyone know what to use if one has some image files lying around and wants to make a PDF of them? O.o
[07:45] <contrapunctus> Okay, got it. 'convert' is pretty cool.
[19:18] <Paul92> hi. I'm trying to configure qjackctl in order to use it with rosegarden for playing on a midi keyboard. First problem :D is when I start qjackctl and I start jack server, I recive the followind message: Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info.
[19:20] <holstein> Paul92: i usually try running JACK as root temporarily, to be sure i have the device configured and all that
[19:20] <holstein> i might close *everything*... open a terminal and run "gksudo qjackctl"
[19:20] <Paul92> if I run it as root, same thing happen
[19:21] <holstein> i would open the "setup" tab and see that the settings are pointing to my device and see that the jack settings are sane
[19:21] <holstein> i would paste the "message" output to pastebin
[19:21] <holstein> !pastebin | Paul92 the output of "messages" in the qjackctl panel
[19:24] <Paul92> http://pastebin.com/PPJKs4yq
[19:24] <Paul92> this is the messages output
[19:25] <holstein> Paul92: and you have a firewire device?
[19:25] <Paul92> to be more specific, I have a keyboard E-MU Xboard 49 and a audiophile 192 soundcard
[19:26] <holstein> the audiophile is firewire?
[19:26] <Paul92> no
[19:26] <Paul92> pci
[19:26] <holstein> Paul92: you have the driver setting set to firewire
[19:27] <holstein> Paul92: i would set that back to the alsa default
[19:27] <holstein> i would consider removing/disabling the internal sound card
[19:27] <holstein> i would look in "setup" under qjackctl and see that the configuration is pointing to the audiophile
[19:28] <zequence> Paul92: You don't really need jack running in order to use your keyboard, but I assume you want to have it running for audio
[19:28] <Paul92> now it works
[19:29] <holstein> Paul92: the firewire driver is just for firewire devices
[19:29] <zequence> Paul92: There are two types of midi. ALSA and Jack. ALSA midi is always on, so you can use qjackctl to make connections even when jack is not running
[19:29] <Paul92> and there is any difference in terms of lantecy?
[19:30] <holstein> Paul92: i have not noticed any effects in latency
[19:31] <zequence> Paul92: It depends on what devices you are using
[19:31] <holstein> though, if you want low latency for using software synths, you'll want jack runing
[19:31] <holstein> running*
[19:31] <zequence> Paul92: Yeah. Midi is not at all connected to audio latency, or audio at all
[19:32] <zequence> Paul92: It's just control data
[19:32] <zequence> Paul92: But, external midi devices can cause a lot of jitter.
[19:33] <zequence> Paul92: And that only happens with ALSA midi AFAIK. But, pretty much only firewire devices do JACK midi with external devices, so you're out of luck there
[19:34] <zequence> Paul92: Anyway, now that you have jack running, give it a try. If you find you have problems with performance, just ask
[19:35] <Paul92> now i have some problems with rosegarden
[19:36] <Paul92> is there something better than rosegarden for what I want to do?
[19:36] <holstein> Paul92: i would check that you are not running jack as root now
[19:36] <holstein> Paul92: i would try starting simple.. maybe get a software synth working
[19:36] <holstein> Paul92: rosegarden makes no sound
[19:36] <zequence> Paul92: If you want lower latency, set frames/period to a lower number. Something like 128 or 64. You will probably get xruns at 64. Disable the pulseaudio bridge to get better performance. To do that, go to qjackctl -> Setup -> Misc -> Enable Dbus interface.
[19:36] <holstein> Paul92: lots of folks use qtractor
[19:36] <zequence> Paul92: Try Hexter
[19:37] <zequence> It's a software synth
[19:37] <zequence> Paul92: Then, use qjackctl to connect your keyboard to hexter
[19:37] <zequence> Paul92: qjackctl -> Connect -> Alsa
[19:51] <Paul92> I have some trouble with hexter. I installed hexter but how do I start it? running hexter in terminal doesn't work
[19:56] <zequence> Paul92: You need to install this as well dssi-host-jack
[19:56] <zequence> I thought you'd have it already, if you were on Ubuntu Studio
[19:57] <zequence> Paul92: A menu item should appear for it
[19:57] <zequence> To start in a terminal: jack-dssi-host hexter.so
[19:57] <Paul92> the problem is i'm not :D i'm on archlinux. I enterd here because...here are people that can help me
[20:08] <Paul92> I managed to start hexter
[20:08] <Paul92> now, how should I make connections?
[20:11] <Paul92> I found it. thank you very much :)
[22:03] <studio-user019> hellow, I installing Ubuntu Studio 12.04
