| virtu | hi | 00:03 |
|---|---|---|
| ajwill | hi all, I was wondering, is it possible to go from normal ubuntu 10.10 to ubuntu studio 10.4 or 10.10 without formatting and re-installing all programs and files and such? | 03:46 |
| holstein | ajwill: i dont know of a way to go back from 10.10 to 10.04 | 03:48 |
| holstein | sudo undo ;0 | 03:48 |
| holstein | ajwill: ubuntustudio = ubuntu | 03:48 |
| holstein | SO you can always just add whatever software you want to your current ubuntu install | 03:48 |
| holstein | i would suggest search where ever you install packages | 03:49 |
| holstein | synaptic, software center, apt-cache search... | 03:49 |
| ajwill | but one problem I'm having is Jack seems to refuse to work on my comp... I tried for like 4 hours today to get it to work and still got nothing | 03:49 |
| holstein | search for ubuntustudio | 03:49 |
| holstein | and read about the meta packages | 03:49 |
| holstein | ajwill: what is the error? | 03:49 |
| holstein | ajwill: actually | 03:49 |
| holstein | what hardware are we talking about | 03:49 |
| holstein | an internal sound card? | 03:50 |
| ajwill | yes, I have no external sound anything besides the fact that I want to record my GT-10 plugged via usb into my computer | 03:50 |
| holstein | OK | 03:50 |
| holstein | open a terminal | 03:50 |
| holstein | and typr | 03:50 |
| holstein | type* | 03:51 |
| holstein | sudo qjackctl | 03:51 |
| holstein | then | 03:51 |
| holstein | open 'setup' | 03:51 |
| holstein | and lets look at the settings | 03:51 |
| ajwill | can I just open qjackctl normally in user? | 03:51 |
| holstein | not yet | 03:51 |
| ajwill | okay | 03:51 |
| holstein | you can if you want | 03:51 |
| holstein | this will test for permissions errors though | 03:51 |
| holstein | then we will hopefully learn why it aint 'giving up the funk' ;) | 03:52 |
| ajwill | okay | 03:52 |
| ajwill | I have it open and I'm in the settings window | 03:52 |
| holstein | in the center | 03:52 |
| holstein | frames/period | 03:52 |
| holstein | set that to 512 | 03:53 |
| ajwill | done | 03:53 |
| holstein | sample rate | 03:53 |
| holstein | 44100 | 03:53 |
| ajwill | done | 03:53 |
| holstein | periods/buffer 3 | 03:53 |
| ajwill | done | 03:53 |
| holstein | above that | 03:53 |
| holstein | 'driver' | 03:53 |
| holstein | what is that set to? | 03:53 |
| ajwill | alsa | 03:53 |
| holstein | alsa? | 03:53 |
| holstein | cool | 03:53 |
| ajwill | yes | 03:53 |
| holstein | say OK | 03:53 |
| holstein | and try hitting 'start' | 03:54 |
| ajwill | okay done | 03:54 |
| holstein | back out on the main panel | 03:54 |
| holstein | whats the good news? | 03:55 |
| ajwill | its working, but the latency is higher than most suggest having it | 03:55 |
| holstein | ajwill: COOL | 03:55 |
| holstein | progress :) | 03:55 |
| holstein | OK | 03:55 |
| holstein | stop it | 03:55 |
| holstein | and close it | 03:55 |
| holstein | and lets run | 03:55 |
| holstein | in a terminal | 03:55 |
| ajwill | okay | 03:56 |
| ajwill | terminal open.. | 03:56 |
| holstein | sudo adduser ajwill audio | 03:56 |
| holstein | ASSUMING | 03:56 |
| holstein | the username on your box is ajwill | 03:56 |
| holstein | i would run... | 03:56 |
| ajwill | okay | 03:56 |
| holstein | sudo adduser holstein audio | 03:56 |
| holstein | this adds your user to the audio group | 03:56 |
| ajwill | done | 03:56 |
| holstein | OK | 03:57 |
| holstein | you might need to log out and back in for that to take effect | 03:57 |
| holstein | i forget :/ | 03:57 |
| holstein | BUT try JACK | 03:57 |
| holstein | as normal user | 03:57 |
| holstein | if it doesnt start | 03:57 |
| ajwill | I did it earlier today from googling stuff andthat's already done | 03:57 |
| holstein | log out and back in | 03:57 |
| holstein | then try | 03:57 |
| holstein | and i that doesnt work... let me know | 03:57 |
| holstein | ajwill: so you were already in the audio group? | 03:58 |
| ajwill | yes | 03:58 |
| ajwill | its working | 03:58 |
| holstein | cool | 03:58 |
| holstein | SO | 03:59 |
| holstein | when jack is stopped | 03:59 |
| holstein | you can tweak the settings | 03:59 |
| holstein | the ones in the center are the ones we mess with | 03:59 |
| holstein | the... | 03:59 |
| holstein | frames/period | 03:59 |
| holstein | and periods/buffer | 03:59 |
| holstein | with an internal card | 03:59 |
| holstein | i feel like 20ms stable is pretty good | 03:59 |
| holstein | you might be able to push to under 10ms | 04:00 |
| holstein | ajwill: IF your not doing any realtime effects processing | 04:00 |
| holstein | OR running softsynths live | 04:00 |
| holstein | you really dont need lower latency | 04:00 |
| holstein | depends on what your needs are | 04:00 |
| ajwill | the current latency is 34.8 and just a note, whenever I start it, it says there's an error, but then it starts normally | 04:00 |
| holstein | ajwill: probably an older error in the window | 04:01 |
| holstein | its kind of a running log | 04:01 |
| holstein | sort of | 04:01 |
| ajwill | and I may want to eventually use synths and such to write my own other stuff but for now its fine | 04:01 |
| ajwill | yes but every time I start it | 04:01 |
| ajwill | it pops up again | 04:01 |
| holstein | yeah | 04:01 |
| ajwill | over in the tray icon | 04:01 |
| holstein | OH | 04:01 |
| holstein | an xrun? | 04:01 |
| ajwill | saying that it's not working | 04:01 |
| ajwill | but then it works | 04:01 |
| holstein | when you start? | 04:01 |
| ajwill | nope | 04:01 |
| holstein | hmmm | 04:01 |
| holstein | in the 'window' | 04:02 |
| holstein | 'messages' window | 04:02 |
| holstein | ? | 04:02 |
| holstein | try clicking on 'messages' | 04:02 |
| ajwill | it pops up saying that it could not connect to jack server as client in messages | 04:02 |
| ajwill | and then goes through a bunch of other stuff | 04:02 |
| ajwill | then works... | 04:02 |
| holstein | and see if that keeps the messages from popping up | 04:02 |
| holstein | when i click on 'messages' right now | 04:03 |
| holstein | i get a window that opens | 04:03 |
| holstein | with a log | 04:03 |
| holstein | from whenever i was running JACK on here last | 04:03 |
| holstein | ajwill: xruns are bad | 04:03 |
| holstein | other than that | 04:03 |
| holstein | i wouldnt worry | 04:03 |
| holstein | you can try different kernels if you want | 04:03 |
| holstein | -lowlatency and -realtime | 04:03 |
| ajwill | okay well there's no xruns and it does pop up with that error every time, but it still works fine so I wont worry about it | 04:04 |
| holstein | http://jackschnippes.freeunix.net/index.php/2010/11/04/lowlatency-kernel-and-realtime-kernel-for-ubuntu-10-10-maverick | 04:04 |
| holstein | ajwill: JACK will just remember that 'messages' window status | 04:05 |
| holstein | that it is open | 04:05 |
| holstein | ALSO | 04:05 |
| holstein | im not running 10.10 | 04:05 |
| holstein | so it could be something funky in that JACK verion that im not aware of | 04:05 |
| ajwill | could be... | 04:06 |
| holstein | ajwill: if your running 10.10, check out that link later on if you want to run a realtime kernel | 04:06 |
| ajwill | oh haha I just tried running with a lower frames/period and it didnt work... | 04:06 |
| holstein | in 10.04, you can install linux-rt | 04:06 |
| holstein | ajwill: yeah, its a lot to ask of an onboard card | 04:06 |
| holstein | and a generic kernel | 04:06 |
| ajwill | how much does a non-on board card cost? | 04:07 |
| holstein | totally depends | 04:07 |
| holstein | the maudio delta 1010lt is resonable | 04:07 |
| holstein | has 2 mic preamps | 04:07 |
| holstein | 10 channels in total | 04:07 |
| holstein | not balanced though | 04:07 |
| holstein | and no phantom power | 04:07 |
| holstein | otherwise i would have got one :) | 04:07 |
| ajwill | ahhh haha | 04:08 |
| holstein | i think they are around a buck fifty US | 04:08 |
| holstein | really nice quality for the $$ and good support | 04:08 |
| ajwill | only a buck fifty? or as in $150? | 04:08 |
| holstein | yeah | 04:08 |
| holstein | $150 | 04:08 |
| ajwill | oh haha | 04:08 |
| holstein | or so | 04:08 |
| ajwill | had me excited there :P | 04:08 |
| holstein | i like the idea of the zoom H4 | 04:09 |
| holstein | 2 nice mics onboard | 04:09 |
| holstein | 2 other nice preamps | 04:09 |
| holstein | balanced phantom power | 04:09 |
| holstein | stand alone mode | 04:09 |
| holstein | works well in JACK | 04:09 |
| holstein | i think they are around $300 | 04:09 |
| ajwill | okay new problem! | 04:09 |
| holstein | im not bit into USB devices though | 04:10 |
| holstein | i have a presonus firepod | 04:10 |
| holstein | you can get one under $400 | 04:10 |
| holstein | 8 balanced mic pre's :) | 04:10 |
| holstein | ajwill: whats up? | 04:10 |
| ajwill | qjackctl wont rn | 04:10 |
| ajwill | *run | 04:10 |
| holstein | ajwill: what did you change? | 04:10 |
| holstein | try and set it back to | 04:10 |
| holstein | 512/3 | 04:10 |
| holstein | or 1024/3 even | 04:11 |
| ajwill | I changed the frames/period and then it froze when I tried to start it, now I cant open it again | 04:11 |
| holstein | jack is one of those things you kinda have to live in for a bit | 04:11 |
| ajwill | oo success! I got it to run at an under 20ms latency... | 04:12 |
| holstein | ajwill: sweet :) | 04:12 |
| ajwill | one more attempt at lowering it to 256/2... | 04:12 |
| holstein | dont worry too much about latency | 04:13 |
| holstein | i say | 04:13 |
| holstein | i have a couple different JACK profiles | 04:13 |
| holstein | i have one thats around 2ms | 04:13 |
| holstein | 1.7 or so | 04:13 |
| holstein | i use that for live stuff | 04:13 |
| holstein | usually im tracking at around 11ms | 04:13 |
| ajwill | ah | 04:13 |
| holstein | and mixing at more like 40ms or more | 04:13 |
| ajwill | thats pretty good then I have.. 17.4ms working | 04:13 |
| holstein | ajwill: you'll really see when you start opening jack apps | 04:14 |
| holstein | and connecting things | 04:14 |
| holstein | how stable it is | 04:14 |
| holstein | i think 20ms would be ideal for you | 04:14 |
| holstein | with that kernel and card | 04:14 |
| holstein | for now | 04:14 |
| ajwill | okay, then I'll get it back down to 20ms so it doesnt crash when I open a program :P | 04:15 |
| ajwill | do you think 34ms is fine? because when I run it at 24 I get a couple messages saying something about xruns | 04:16 |
| ajwill | ?? | 04:18 |
| ajwill | owait nvm I get a thing saying "xrun of at least 2.418msecs" even at 34.8ms... | 04:18 |
| holstein | ajwill: i think you can get under 30 with a different kernel later | 04:19 |
| holstein | BUT i think even 60ms wouldnt matter much right now | 04:19 |
| holstein | i would just get it stable | 04:19 |
| holstein | and play around with some things | 04:19 |
| ajwill | okay | 04:19 |
| holstein | to be honest | 04:19 |
| holstein | i find over 12ms to be a bit un-tolerable | 04:19 |
| holstein | with soft synths | 04:19 |
| holstein | so i wouldnt sweat it right now | 04:20 |
| ajwill | what's a good recording program? I've tried ardour and I dont like that you cant have it click in before you start | 04:20 |
| holstein | AH | 04:20 |
| holstein | you can | 04:20 |
| holstein | ajwill: ardour has a crazy learing curve | 04:20 |
| holstein | that what i use though | 04:20 |
| holstein | ajwill: check out #opensourcemusicians | 04:21 |
| holstein | lots of folk use different DAW's there | 04:21 |
| holstein | and talk about them | 04:21 |
| ajwill | hm okay | 04:21 |
| holstein | qtractor | 04:21 |
| holstein | renoise | 04:21 |
| ajwill | well one question I have | 04:21 |
| holstein | i dont think audacity is a good option | 04:21 |
| ajwill | is it possible to get a like 8 beat click in with ardour? | 04:21 |
| holstein | ajwill: sure | 04:21 |
| ajwill | and I totally agree with you on that one | 04:21 |
| ajwill | how? I need that and once I have that ardour will be fine | 04:22 |
| holstein | its possible to que hydrogen drum machine up | 04:22 |
| holstein | have it play 8 bars | 04:22 |
| holstein | before you track in ardour | 04:22 |
| holstein | 8 beats * | 04:22 |
| ajwill | would you suggest just starting with ardour and using it? | 04:22 |
| ajwill | or should I look for something more user friendly? like jokosher? | 04:23 |
| holstein | ajwill: i cant really say | 04:23 |
| holstein | i find its the best tool for me | 04:23 |
| ajwill | what kind of recording do you do? | 04:23 |
| holstein | and #ardour is *so* helpful | 04:23 |
| holstein | ajwill: mostly live stuff | 04:23 |
| holstein | not midi | 04:23 |
| holstein | http://holstein.shacknet.nu/rupert/ | 04:24 |
| holstein | ^^ thats the most recent thing im mostly done with | 04:24 |
| ajwill | hm, thats rlly good! | 04:25 |
| holstein | thanks :) | 04:25 |
| holstein | turned out pretty well i think | 04:26 |
| ajwill | my limit atm is just doing home recording for youtube covers and such :P | 04:26 |
| holstein | cool | 04:26 |
| holstein | you might enjoy the community over at #opensourcemusicians | 04:27 |
| ajwill | I probably would haha, maybe I'll go there to get advice on a daw to use... | 04:27 |
| ajwill | so is opensourcemuscians an irc for linux musicians? | 04:28 |
| holstein | theres a guy that was doing 'pomplamoose' esque vids | 04:28 |
| holstein | really good ones :) | 04:28 |
| holstein | ajwill: yeah, its on freenode | 04:29 |
| holstein | just /j #opensourcemusicians | 04:29 |
| holstein | or /join | 04:29 |
| ajwill | joined | 04:29 |
| ajwill | hmm | 04:29 |
| _pg_ | I just installed a slew of updates on my persistent usb install and now there is a login screen, the credentials "ubuntu" and "blank" seem to try to login but then it blanks back to the login screen. Any ideas? | 05:35 |
| holstein | _pg_: can you use an older kernel? | 05:37 |
| holstein | i think you push shift at some point | 05:37 |
| holstein | to see grub2's list | 05:37 |
| _pg_ | holstein: hmm, ill try that | 05:37 |
| _pg_ | holstein: thanx | 05:37 |
| holstein | worth a try :) | 05:37 |
| domjohnson | Hi | 10:40 |

| hxod | Hello, I work in a kind of indepent project of art production in the brazilian amazon. Then, I wanna try ubuntustudio, but Gnome is "freezed" here. Does anyone have any clue, please? | 11:40 |
| hxod | Does anyone could help? The system boots normaly, I login, and then the background's screen appears (normaly), I can move the mouse, but there are no panel and nothing else (eventhough I can change to desktop 2, 3 and 4. :P | 11:59 |
