| 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 | 07:18 |

| contrapunctus | Okay, got it. 'convert' is pretty cool. | 07:45 |

| 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. | 19:18 |
| 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 | 19:20 |
| 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 | 19:21 |

| Paul92 | this is the messages output | 19:24 |
| 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 | 19:25 |
| 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 | 19:26 |
| 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 | 19:27 |
| 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 | 19:28 |
| 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? | 19:29 |
| holstein | Paul92: i have not noticed any effects in latency | 19:30 |
| 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 | 19:31 |
| zequence | Paul92: It's just control data | 19:32 |
| zequence | Paul92: But, external midi devices can cause a lot of jitter. | 19:32 |
| 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 | 19:33 |
| zequence | Paul92: Anyway, now that you have jack running, give it a try. If you find you have problems with performance, just ask | 19:34 |
| Paul92 | now i have some problems with rosegarden | 19:35 |
| 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 | 19:36 |
| 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 | 19:37 |
| Paul92 | I have some trouble with hexter. I installed hexter but how do I start it? running hexter in terminal doesn't work | 19:51 |
| 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 | 19:56 |
| 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 | 19:57 |
| Paul92 | I managed to start hexter | 20:08 |
| Paul92 | now, how should I make connections? | 20:08 |
| Paul92 | I found it. thank you very much :) | 20:11 |
| studio-user019 | hellow, I installing Ubuntu Studio 12.04 | 22:03 |
