[00:03] hi [03:46] 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? [03:48] ajwill: i dont know of a way to go back from 10.10 to 10.04 [03:48] sudo undo ;0 [03:48] ajwill: ubuntustudio = ubuntu [03:48] SO you can always just add whatever software you want to your current ubuntu install [03:49] i would suggest search where ever you install packages [03:49] synaptic, software center, apt-cache search... [03:49] 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] search for ubuntustudio [03:49] and read about the meta packages [03:49] ajwill: what is the error? [03:49] ajwill: actually [03:49] what hardware are we talking about [03:50] an internal sound card? [03:50] 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] OK [03:50] open a terminal [03:50] and typr [03:51] type* [03:51] sudo qjackctl [03:51] then [03:51] open 'setup' [03:51] and lets look at the settings [03:51] can I just open qjackctl normally in user? [03:51] not yet [03:51] okay [03:51] you can if you want [03:51] this will test for permissions errors though [03:52] then we will hopefully learn why it aint 'giving up the funk' ;) [03:52] okay [03:52] I have it open and I'm in the settings window [03:52] in the center [03:52] frames/period [03:53] set that to 512 [03:53] done [03:53] sample rate [03:53] 44100 [03:53] done [03:53] periods/buffer 3 [03:53] done [03:53] above that [03:53] 'driver' [03:53] what is that set to? [03:53] alsa [03:53] alsa? [03:53] cool [03:53] yes [03:53] say OK [03:54] and try hitting 'start' [03:54] okay done [03:54] back out on the main panel [03:55] whats the good news? [03:55] its working, but the latency is higher than most suggest having it [03:55] ajwill: COOL [03:55] progress :) [03:55] OK [03:55] stop it [03:55] and close it [03:55] and lets run [03:55] in a terminal [03:56] okay [03:56] terminal open.. [03:56] sudo adduser ajwill audio [03:56] ASSUMING [03:56] the username on your box is ajwill [03:56] i would run... [03:56] okay [03:56] sudo adduser holstein audio [03:56] this adds your user to the audio group [03:56] done [03:57] OK [03:57] you might need to log out and back in for that to take effect [03:57] i forget :/ [03:57] BUT try JACK [03:57] as normal user [03:57] if it doesnt start [03:57] I did it earlier today from googling stuff andthat's already done [03:57] log out and back in [03:57] then try [03:57] and i that doesnt work... let me know [03:58] ajwill: so you were already in the audio group? [03:58] yes [03:58] its working [03:58] cool [03:59] SO [03:59] when jack is stopped [03:59] you can tweak the settings [03:59] the ones in the center are the ones we mess with [03:59] the... [03:59] frames/period [03:59] and periods/buffer [03:59] with an internal card [03:59] i feel like 20ms stable is pretty good [04:00] you might be able to push to under 10ms [04:00] ajwill: IF your not doing any realtime effects processing [04:00] OR running softsynths live [04:00] you really dont need lower latency [04:00] depends on what your needs are [04:00] 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 [04:01] ajwill: probably an older error in the window [04:01] its kind of a running log [04:01] sort of [04:01] and I may want to eventually use synths and such to write my own other stuff but for now its fine [04:01] yes but every time I start it [04:01] it pops up again [04:01] yeah [04:01] over in the tray icon [04:01] OH [04:01] an xrun? [04:01] saying that it's not working [04:01] but then it works [04:01] when you start? [04:01] nope [04:01] hmmm [04:02] in the 'window' [04:02] 'messages' window [04:02] ? [04:02] try clicking on 'messages' [04:02] it pops up saying that it could not connect to jack server as client in messages [04:02] and then goes through a bunch of other stuff [04:02] then works... [04:02] and see if that keeps the messages from popping up [04:03] when i click on 'messages' right now [04:03] i get a window that opens [04:03] with a log [04:03] from whenever i was running JACK on here last [04:03] ajwill: xruns are bad [04:03] other than that [04:03] i wouldnt worry [04:03] you can try different kernels if you want [04:03] -lowlatency and -realtime [04:04] 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] http://jackschnippes.freeunix.net/index.php/2010/11/04/lowlatency-kernel-and-realtime-kernel-for-ubuntu-10-10-maverick [04:05] ajwill: JACK will just remember that 'messages' window status [04:05] that it is open [04:05] ALSO [04:05] im not running 10.10 [04:05] so it could be something funky in that JACK verion that im not aware of [04:06] could be... [04:06] ajwill: if your running 10.10, check out that link later on if you want to run a realtime kernel [04:06] oh haha I just tried running with a lower frames/period and it didnt work... [04:06] in 10.04, you can install linux-rt [04:06] ajwill: yeah, its a lot to ask of an onboard card [04:06] and a generic kernel [04:07] how much does a non-on board card cost? [04:07] totally depends [04:07] the maudio delta 1010lt is resonable [04:07] has 2 mic preamps [04:07] 10 channels in total [04:07] not balanced though [04:07] and no phantom power [04:07] otherwise i would have got one :) [04:08] ahhh haha [04:08] i think they are around a buck fifty US [04:08] really nice quality for the $$ and good support [04:08] only a buck fifty? or as in $150? [04:08] yeah [04:08] $150 [04:08] oh haha [04:08] or so [04:08] had me excited there :P [04:09] i like the idea of the zoom H4 [04:09] 2 nice mics onboard [04:09] 2 other nice preamps [04:09] balanced phantom power [04:09] stand alone mode [04:09] works well in JACK [04:09] i think they are around $300 [04:09] okay new problem! [04:10] im not bit into USB devices though [04:10] i have a presonus firepod [04:10] you can get one under $400 [04:10] 8 balanced mic pre's :) [04:10] ajwill: whats up? [04:10] qjackctl wont rn [04:10] *run [04:10] ajwill: what did you change? [04:10] try and set it back to [04:10] 512/3 [04:11] or 1024/3 even [04:11] I changed the frames/period and then it froze when I tried to start it, now I cant open it again [04:11] jack is one of those things you kinda have to live in for a bit [04:12] oo success! I got it to run at an under 20ms latency... [04:12] ajwill: sweet :) [04:12] one more attempt at lowering it to 256/2... [04:13] dont worry too much about latency [04:13] i say [04:13] i have a couple different JACK profiles [04:13] i have one thats around 2ms [04:13] 1.7 or so [04:13] i use that for live stuff [04:13] usually im tracking at around 11ms [04:13] ah [04:13] and mixing at more like 40ms or more [04:13] thats pretty good then I have.. 17.4ms working [04:14] ajwill: you'll really see when you start opening jack apps [04:14] and connecting things [04:14] how stable it is [04:14] i think 20ms would be ideal for you [04:14] with that kernel and card [04:14] for now [04:15] okay, then I'll get it back down to 20ms so it doesnt crash when I open a program :P [04:16] do you think 34ms is fine? because when I run it at 24 I get a couple messages saying something about xruns [04:18] ?? [04:18] owait nvm I get a thing saying "xrun of at least 2.418msecs" even at 34.8ms... [04:19] ajwill: i think you can get under 30 with a different kernel later [04:19] BUT i think even 60ms wouldnt matter much right now [04:19] i would just get it stable [04:19] and play around with some things [04:19] okay [04:19] to be honest [04:19] i find over 12ms to be a bit un-tolerable [04:19] with soft synths [04:20] so i wouldnt sweat it right now [04:20] 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] AH [04:20] you can [04:20] ajwill: ardour has a crazy learing curve [04:20] that what i use though [04:21] ajwill: check out #opensourcemusicians [04:21] lots of folk use different DAW's there [04:21] and talk about them [04:21] hm okay [04:21] qtractor [04:21] renoise [04:21] well one question I have [04:21] i dont think audacity is a good option [04:21] is it possible to get a like 8 beat click in with ardour? [04:21] ajwill: sure [04:21] and I totally agree with you on that one [04:22] how? I need that and once I have that ardour will be fine [04:22] its possible to que hydrogen drum machine up [04:22] have it play 8 bars [04:22] before you track in ardour [04:22] 8 beats * [04:22] would you suggest just starting with ardour and using it? [04:23] or should I look for something more user friendly? like jokosher? [04:23] ajwill: i cant really say [04:23] i find its the best tool for me [04:23] what kind of recording do you do? [04:23] and #ardour is *so* helpful [04:23] ajwill: mostly live stuff [04:23] not midi [04:24] http://holstein.shacknet.nu/rupert/ [04:24] ^^ thats the most recent thing im mostly done with [04:25] hm, thats rlly good! [04:25] thanks :) [04:26] turned out pretty well i think [04:26] my limit atm is just doing home recording for youtube covers and such :P [04:26] cool [04:27] you might enjoy the community over at #opensourcemusicians [04:27] I probably would haha, maybe I'll go there to get advice on a daw to use... [04:28] so is opensourcemuscians an irc for linux musicians? [04:28] theres a guy that was doing 'pomplamoose' esque vids [04:28] really good ones :) [04:29] ajwill: yeah, its on freenode [04:29] just /j #opensourcemusicians [04:29] or /join [04:29] joined [04:29] hmm [05:35] <_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? [05:37] _pg_: can you use an older kernel? [05:37] i think you push shift at some point [05:37] to see grub2's list [05:37] <_pg_> holstein: hmm, ill try that [05:37] <_pg_> holstein: thanx [05:37] worth a try :) [10:40] Hi [10:41] Has anyone got an Intuos4 working in 10.10? [11:40] 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? [11:59] 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 [12:46] Hello, I work in a kind of indepent project of art production in the brazilian amazon.
