rebirthman, can someone help me? i'm trying to do some pretty basic stuff and i haven't been able to get anything to work quite right. i created a composition in rosegarden and i want to now record a live instrument via a mic using the composition as a guide07:40
rebirthrosegarden keeps crashing and not recording the audio in sync, audacity won;t import the midi and i can't figure out how to use aurdour07:40
holsteinhey rebirth08:07
holsteinsorry to see your having so much trouble08:07
holsteinone way to do it would be08:07
holsteinroute the MIDI tracks into audacity08:08
holsteinthen you can record them08:08
holsteinthen record your audio in a separate track08:08
holsteinthen as long as you keep the 'zeros' lined up08:08
holsteinyou can go back and re-do the MIDI if needed08:09
holsteinand add the audio you already recorded08:09
holsteinthe guys in #ardour are usually very helpful too08:10
rebirththanks holstein i'm sure i'll figure it out08:21
holsteinrebirth: :)08:21
vattsyaaaaaaaaay it boots10:54
vattsok where is now the video editing app?*Sights*10:54
astraljavavatts: Maverick install?11:05
vattsastraljava, eeeeeeeeeeeee?11:05
vattsdled last one11:05
vattscouple weeks ago... not more than 1 month11:06
vattsi went for video editing core...^11:06
astraljavaOk, probably Lucid then.11:06
astraljavaJust asking as I have trouble testing the maverick amd64 install.11:07
zylogz80hi everyone. I am trying to better understand latency with JACK. What are reasonable expectations for latency? What are latencies other people are using? I've got a Core i5 system with 4GB of ram and an MAudio USB interface. I can't seem to attain latencies under 20ms without problems like distortion or audio artifacts and latencies below 10ms result in xruns and hangs.16:30
zylogz80I had an older slower machine that I recorded at 45ms and didn't really notice a problem. With this new i5 machine I wanted to know what I should be shooting for. I saw the ubuntustudio JACK how-to and the example shows sub 6ms. If I try those settings I get hundreds of xruns right on start16:32
zylogz80hmmm. well. maybe I just hit on something. I was able to start with 5ms with no xruns when I selected "none" for the midi driver16:34
zylogz80can raw and seq cause xruns?16:34
zylogz80too easy I guess. the xruns started as soon as I started an application.16:36
holsteinhey zylogz8016:37
zylogz80holstein, hi16:38
holsteinthere are lots of factors16:38
holsteini had a P4 with a gig of ram16:38
holsteinand a presonus firepod16:38
holsteini could get under 5ms stable16:38
holsteini could push that to around 2ms for live softsynths16:39
holsteini would usually use a JACK preset for around 60ms to mix though16:39
holsteinseemed faster with a bunch of plugins running16:39
holsteinand at that point i wasnt worried about the latency anymore16:40
holsteinzylogz80: i think the first question should be 'do i need lower latency?'16:40
zylogz80holstein, well I felt ok at 45ms on my old computer but some things felt a bit laggy, like playing guitar and what now. I was hoping by buying a faster computer I could help that16:41
holsteinopen a terminal16:42
holsteinand run16:42
holsteincat /proc/interrupts16:42
zylogz80holstein, want me to pastebin it?16:42
holsteinyou can16:42
holsteinthis is showing what all is sharing an IRQ address with your sound device16:43
holsteinand the USB port that is controlling the sound device16:43
zylogz80holstein, http://ubuntu.pastebin.com/n8YAZV8N16:43
zylogz80holstein, ok let me try to read it and understand it16:43
holsteinyou go in the bios and get both of these off by themselves16:43
holsteinzylogz80: actually, i think that looks good16:45
holsteinyou can check the bios, and see what it says16:45
holsteinbut that pastebin makes me think you got it all seperated pretty well16:45
holsteinzylogz80: what kernel are you using?16:46
holsteinin terminal16:46
holsteinuname -a16:46
zylogz80holstein, thanks16:46
zylogz80holstein, Linux adam-laptop 2.6.32-24-generic #43-Ubuntu SMP Thu Sep 16 14:17:33 UTC 2010 i686 GNU/Linux16:46
holsteinyou can try a different kernel16:46
holsteini like the realtime one16:46
holsteinbut it is suggested to try the -lowlatency one first16:47
holsteini usually just skip to the googs :)16:47
holsteinsudo apt-get install linux-rt16:47
zylogz80holstein, hmmm. I ran my old machine off the realtime kernel16:47
holsteinthen you need to16:48
zylogz80holstein, I was going to use it on this one but I have some hardware problems with it :( I was hoping to avoid it.16:48
holsteinOH, nvidia graphics?16:48
zylogz80holstein, I asked around in #jack and I couldn't get a real clear answer on whether or not the realtime kernel was required16:48
holsteinzylogz80: no16:48
holsteinits not required16:48
zylogz80holstein, no I specifically picked a machine without an nvidia or ati card16:48
holsteinand work is being done so that the generic one will have preemnt-ing16:49
holsteinbut, i still need the RT one16:49
zylogz80holstein, I'll need to boot into the realtime kernel and see what I get on this hardware16:49
holsteindid you try https://launchpad.net/~abogani/+archive/ppa16:49
holsteinabogani's -realtime kernel?16:50
zylogz80holstein, but I am unable to use wifi on the realtime kernel which is a bummer :( I didn't mind the realtime kernel on my last box because I could just efault boot into it but on this one I think I'll have to boot into it for audio work and back into a normal kernel regular16:50
holsteinthe linux-rt kernel in the lucid repos is the one from karmic16:50
zylogz80holstein, no I haven't seen that. let me take a look16:50
holsteinzylogz80: OH16:50
holsteinis this a laptop?16:50
zylogz80holstein, yes16:50
holsteinthat can throw up an xrun16:51
holsteini like to try and do wired16:51
zylogz80holstein, wifi?16:51
holsteinOR no internet16:51
holsteini network and do netjack though16:51
holsteinbut with my laptop16:51
holsteini wire it16:51
zylogz80holstein, ok. I can see where that gets me.16:51
zylogz80holstein, what are you getting for latency?16:52
holsteini got a new box16:52
holsteina dual core AMD16:52
holsteinwith 3 gigs of ram16:52
holsteinso i can do 2ms stable16:52
holsteinand i can push it under 1 ;)16:52
holsteinbut i dont16:52
holsteinand again16:53
holsteini mix with it set at like 20 or so16:53
zylogz80holstein, I would really love to get to that. I bought a new laptop specifically for audio. my old one was fine for every day stuff. I'd really hate to not fegire this out. I really apprecieate your help though. :)16:53
holsteinim not sure about with the USB16:53
zylogz80holstein, what do you use for an interface?16:53
holsteinyou shoud be able to get 5 or so though16:53
zylogz80holstein, yeah 5-6 would be more than great coming from almost 5016:54
holsteinpresonus firepod16:54
holsteinzylogz80: if you use abogani's PPA, the RT kernel is called linux-realtime16:54
holsteinzylogz80: you might also benefit from16:55
zylogz80holstein, cool looking peice of gear. I'd need to get a firewire express card interface or something16:55
holstein^^ some of the stuff in falks ppa16:55
holsteinfrom what i read16:55
holsteinutilizes multiple cores16:56
holsteinzylogz80: IF you get a firewire card16:56
zylogz80holstein, interesting16:56
holsteintry and get a texas instruments chipset16:56
holsteinOR save the recipts ;)16:56
zylogz80holstein, thanks for the tips. I really appreciate the help. These ppas look interesting16:57
holsteinzylogz80: i use http://ubuntu-tweak.com/16:57
holsteinthere is a PPA purge option added16:58
holsteinSO if you get falks ppa going16:58
holsteinand it borks something16:58
holsteinyou can get out16:58
holsteinhe's got abogani's kernels in there too16:58
holsteinzylogz80: there are a bunch of KXstudio specific packages in there that i would avoid16:58
holsteinother than that, i think its safe to add the PPA16:59
zylogz80holstein, cool. yeah I would be looking mostly at the realtime kernel and some soundfonts for qsynth16:59
holsteinand do an upgrade16:59
zylogz80holstein, ubuntu tweak looks really helpful16:59
holsteini started using it for PPA purge17:00
holsteinbut some of the gconf tweaking is easier to find with it17:00
zylogz80holstein, so if I mess something up it'll remove all the packages I installed form that ppa?17:00
holsteinzylogz80: you just open tweak17:00
holsteinand say 'purge PPA'17:00
holsteinand it'll remove what you installed from that PPA17:01
holsteinand downgrade whatever needs to be downgraded17:01
* holstein tested17:01
holsteinwith that PPA acutally17:01
holsteini tested on my laptop17:01
zylogz80holstein, very cool. ubuntu tweak seems really neat17:01
holsteinbefore doing it on my main studio machine17:01
holsteini wanted to make sure there was an 'easy' way back to JACK 117:02
zylogz80holstein, I've got great backups and I may test in a virtual machine first just to make sure I understand the process17:02
holsteinzylogz80: i totally understand that17:02
holsteini just wanted to let you know that its pretty much 'safe'17:03
holsteinand that i have tested it17:03
holsteinbut i would do the same :)17:03
zylogz80holstein, thanks very much. you've given me a whole bunch of leads to chase down. I really apprecieate it.17:04
zylogz80holstein, I'll check if you're on later and let you know how everything panned out17:04
holsteinzylogz80: OH17:04
holsteinand one more17:04
holsteinvery helpful folk :)17:05
holsteinzylogz80: good luck17:05
zylogz80holstein, thanks!17:05
ronjhi there17:16
ronjtoday's daily spin of ubuntustudio fails to install at "select and install software" step and presents a red screen asking to retry or skip, even if I uncheck all of the four choices (2d3d, audio, dssi, video). should I file a bug or report on the ML or provide more info here?17:18
holsteinronj: i think its already there ??17:19
holsteinits known17:19
holsteinronj: are you on the email list?17:19
ronjholstein, ok; didn't know17:19
holsteinyou might want to send an email there so its documented17:19
holsteinbut it was yesterday or the day before i say some talk about hat17:20
ronjholstein, yup but I stopped looking at it a long time ago and now that I bought a machine dedicated to testing I'm trying to get back on the train :P17:20
holsteinronj: HEY17:20
holsteinthats great :)17:20
holsteiniso testing is greatly appreciated17:21
ronjholstein, were you mentioning the user of devel list?17:23
holsteinronj: i think devel would be appropriate17:24
holsteinyou can ask over in ubuntustudio-devel too17:24
prepBrasero is not burning correctly, ejects disc when trying to burn, just started recently18:41
holsteinbad discs?18:41
prepNope, was burning ok last time I burned last week, just started18:42
* holstein is using gnomebaker18:42
holsteinprep: i would try and rule out hardware and discs18:42
holsteinmaybe use a live CD18:43
holsteinand try burning something18:43
holsteinor use a different optical drive18:43
prepUsed the built in cd/dvd creator software, it burned all the tracks, but only track 1 would play, for 1 min, all the others were blank18:43
holsteinwhat is 'built in cd/dvd creator' software?18:44
prepNo, another one. Not at the PC at the moment, not sure the exact name. Came with the distro18:45
holsteinyou have tried 2 different pieces of software18:45
holsteinin the same linux distro18:45
holsteini would probably install gnomebaker18:46
holsteinand then, try burning from a live CD18:46
holsteinthen, i would start thinking its hardware18:46
holsteini got a stack of bad optical drives :)18:46
holsteinthey die18:46
prepweird it just started. Was burning fine18:46
prepwas thinking maybe a software conflict18:47
holsteinwhen my LG died18:47
holsteinthat how it went18:47
holsteinbut LG replaced it :)18:47
prepWhen 10.10 is out, i'm staying put18:47
holsteinprep: probably not going to have a software conflict18:47
holsteinif you stay pretty much in the repo18:47
holsteinthings are pretty well tested18:47
holsteinyeah, it could be a maverick thing18:48
prepyeah haven't added any disc burn software18:48
holsteini would try a lucid live disc18:48
prepyeah dont forget I'm a Maverick cripple18:48
holsteinnow you know18:48
prepaight, at work. I'm out. Be easy18:48
holsteinprep: laterx18:49
prepwe'll try to troubleshoot it tomorrow. .18:49
