[07:18] 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] Okay, got it. 'convert' is pretty cool. === 20WABM4XS is now known as jussi === jussi is now known as jussi01 === jussi01 is now known as jussi [19:18] 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] Paul92: i usually try running JACK as root temporarily, to be sure i have the device configured and all that [19:20] i might close *everything*... open a terminal and run "gksudo qjackctl" [19:20] if I run it as root, same thing happen [19:21] 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] i would paste the "message" output to pastebin [19:21] !pastebin | Paul92 the output of "messages" in the qjackctl panel [19:21] Paul92 the output of "messages" in the qjackctl panel: For posting multi-line texts into the channel, please use http://paste.ubuntu.com | To post !screenshots use http://imagebin.org/?page=add | !pastebinit to paste directly from command line | Make sure you give us the URL for your paste - see also the channel topic. [19:24] http://pastebin.com/PPJKs4yq [19:24] this is the messages output [19:25] Paul92: and you have a firewire device? [19:25] to be more specific, I have a keyboard E-MU Xboard 49 and a audiophile 192 soundcard [19:26] the audiophile is firewire? [19:26] no [19:26] pci [19:26] Paul92: you have the driver setting set to firewire [19:27] Paul92: i would set that back to the alsa default [19:27] i would consider removing/disabling the internal sound card [19:27] i would look in "setup" under qjackctl and see that the configuration is pointing to the audiophile [19:28] 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] now it works [19:29] Paul92: the firewire driver is just for firewire devices [19:29] 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] and there is any difference in terms of lantecy? [19:30] Paul92: i have not noticed any effects in latency [19:31] Paul92: It depends on what devices you are using [19:31] though, if you want low latency for using software synths, you'll want jack runing [19:31] running* [19:31] Paul92: Yeah. Midi is not at all connected to audio latency, or audio at all [19:32] Paul92: It's just control data [19:32] Paul92: But, external midi devices can cause a lot of jitter. [19:33] 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] Paul92: Anyway, now that you have jack running, give it a try. If you find you have problems with performance, just ask [19:35] now i have some problems with rosegarden [19:36] is there something better than rosegarden for what I want to do? [19:36] Paul92: i would check that you are not running jack as root now [19:36] Paul92: i would try starting simple.. maybe get a software synth working [19:36] Paul92: rosegarden makes no sound [19:36] 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] Paul92: lots of folks use qtractor [19:36] Paul92: Try Hexter [19:37] It's a software synth [19:37] Paul92: Then, use qjackctl to connect your keyboard to hexter [19:37] Paul92: qjackctl -> Connect -> Alsa [19:51] I have some trouble with hexter. I installed hexter but how do I start it? running hexter in terminal doesn't work [19:56] Paul92: You need to install this as well dssi-host-jack [19:56] I thought you'd have it already, if you were on Ubuntu Studio [19:57] Paul92: A menu item should appear for it [19:57] To start in a terminal: jack-dssi-host hexter.so [19:57] the problem is i'm not :D i'm on archlinux. I enterd here because...here are people that can help me [20:08] I managed to start hexter [20:08] now, how should I make connections? [20:11] I found it. thank you very much :) [22:03] hellow, I installing Ubuntu Studio 12.04
