| rebirth | man, 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 guide | 07:40 |
|---|---|---|
| rebirth | rosegarden keeps crashing and not recording the audio in sync, audacity won;t import the midi and i can't figure out how to use aurdour | 07:40 |
| holstein | hey rebirth | 08:07 |
| holstein | sorry to see your having so much trouble | 08:07 |
| holstein | one way to do it would be | 08:07 |
| holstein | route the MIDI tracks into audacity | 08:08 |
| holstein | then you can record them | 08:08 |
| holstein | alone | 08:08 |
| holstein | then record your audio in a separate track | 08:08 |
| holstein | then as long as you keep the 'zeros' lined up | 08:08 |
| holstein | you can go back and re-do the MIDI if needed | 08:09 |
| holstein | later | 08:09 |
| holstein | and add the audio you already recorded | 08:09 |
| holstein | the guys in #ardour are usually very helpful too | 08:10 |
| rebirth | thanks holstein i'm sure i'll figure it out | 08:21 |
| holstein | rebirth: :) | 08:21 |

| vatts | yaaaaaaaaay it boots | 10:54 |
| vatts | :D | 10:54 |
| vatts | ok where is now the video editing app?*Sights* | 10:54 |
| astraljava | vatts: Maverick install? | 11:05 |
| vatts | astraljava, eeeeeeeeeeeee? | 11:05 |
| vatts | dunno | 11:05 |
| vatts | dled last one | 11:05 |
| vatts | couple weeks ago... not more than 1 month | 11:06 |
| vatts | i went for video editing core...^ | 11:06 |
| astraljava | Ok, probably Lucid then. | 11:06 |
| astraljava | Just asking as I have trouble testing the maverick amd64 install. | 11:07 |
| zylogz80 | hi 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 |
| zylogz80 | I 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 start | 16:32 |
| zylogz80 | hmmm. well. maybe I just hit on something. I was able to start with 5ms with no xruns when I selected "none" for the midi driver | 16:34 |
| zylogz80 | can raw and seq cause xruns? | 16:34 |
| zylogz80 | too easy I guess. the xruns started as soon as I started an application. | 16:36 |
| holstein | hey zylogz80 | 16:37 |
| zylogz80 | holstein, hi | 16:38 |
| holstein | there are lots of factors | 16:38 |
| holstein | i had a P4 with a gig of ram | 16:38 |
| holstein | and a presonus firepod | 16:38 |
| holstein | i could get under 5ms stable | 16:38 |
| holstein | i could push that to around 2ms for live softsynths | 16:39 |
| holstein | i would usually use a JACK preset for around 60ms to mix though | 16:39 |
| holstein | seemed faster with a bunch of plugins running | 16:39 |
| holstein | and at that point i wasnt worried about the latency anymore | 16:40 |
| holstein | zylogz80: i think the first question should be 'do i need lower latency?' | 16:40 |
| zylogz80 | holstein, 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 that | 16:41 |
| holstein | nope | 16:41 |
| holstein | open a terminal | 16:42 |
| holstein | and run | 16:42 |
| holstein | cat /proc/interrupts | 16:42 |
| zylogz80 | holstein, want me to pastebin it? | 16:42 |
| holstein | you can | 16:42 |
| holstein | this is showing what all is sharing an IRQ address with your sound device | 16:43 |
| holstein | and the USB port that is controlling the sound device | 16:43 |
| holstein | ideally | 16:43 |
| zylogz80 | holstein, http://ubuntu.pastebin.com/n8YAZV8N | 16:43 |
| zylogz80 | holstein, ok let me try to read it and understand it | 16:43 |
| holstein | you go in the bios and get both of these off by themselves | 16:43 |
| holstein | zylogz80: actually, i think that looks good | 16:45 |
| holstein | you can check the bios, and see what it says | 16:45 |
| holstein | but that pastebin makes me think you got it all seperated pretty well | 16:45 |
| holstein | zylogz80: what kernel are you using? | 16:46 |
| holstein | in terminal | 16:46 |
| holstein | uname -a | 16:46 |
| zylogz80 | holstein, thanks | 16:46 |
| zylogz80 | holstein, Linux adam-laptop 2.6.32-24-generic #43-Ubuntu SMP Thu Sep 16 14:17:33 UTC 2010 i686 GNU/Linux | 16:46 |
| holstein | you can try a different kernel | 16:46 |
| holstein | i like the realtime one | 16:46 |
| holstein | but it is suggested to try the -lowlatency one first | 16:47 |
| holstein | i usually just skip to the googs :) | 16:47 |
| holstein | sudo apt-get install linux-rt | 16:47 |
| zylogz80 | holstein, hmmm. I ran my old machine off the realtime kernel | 16:47 |
| holstein | then you need to | 16:48 |
| zylogz80 | holstein, 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 |
| holstein | OH, nvidia graphics? | 16:48 |
| zylogz80 | holstein, I asked around in #jack and I couldn't get a real clear answer on whether or not the realtime kernel was required | 16:48 |
| holstein | zylogz80: no | 16:48 |
| holstein | its not required | 16:48 |
| zylogz80 | holstein, no I specifically picked a machine without an nvidia or ati card | 16:48 |
| holstein | and work is being done so that the generic one will have preemnt-ing | 16:49 |
| holstein | but, i still need the RT one | 16:49 |
| zylogz80 | holstein, I'll need to boot into the realtime kernel and see what I get on this hardware | 16:49 |
| holstein | zylogz80: | 16:49 |
| holstein | did you try https://launchpad.net/~abogani/+archive/ppa | 16:49 |
| holstein | abogani's -realtime kernel? | 16:50 |
| zylogz80 | holstein, 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 regular | 16:50 |
| holstein | the linux-rt kernel in the lucid repos is the one from karmic | 16:50 |
| zylogz80 | holstein, no I haven't seen that. let me take a look | 16:50 |
| holstein | zylogz80: OH | 16:50 |
| holstein | is this a laptop? | 16:50 |
| holstein | well | 16:50 |
| zylogz80 | holstein, yes | 16:50 |
| holstein | that can throw up an xrun | 16:51 |
| holstein | i like to try and do wired | 16:51 |
| zylogz80 | holstein, wifi? | 16:51 |
| holstein | OR no internet | 16:51 |
| holstein | i network and do netjack though | 16:51 |
| holstein | but with my laptop | 16:51 |
| holstein | i wire it | 16:51 |
| zylogz80 | holstein, ok. I can see where that gets me. | 16:51 |
| zylogz80 | holstein, what are you getting for latency? | 16:52 |
| holstein | well | 16:52 |
| holstein | i got a new box | 16:52 |
| holstein | a dual core AMD | 16:52 |
| holstein | with 3 gigs of ram | 16:52 |
| holstein | so i can do 2ms stable | 16:52 |
| holstein | and i can push it under 1 ;) | 16:52 |
| holstein | but i dont | 16:52 |
| holstein | and again | 16:53 |
| holstein | i mix with it set at like 20 or so | 16:53 |
| zylogz80 | holstein, 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 |
| holstein | yeah | 16:53 |
| holstein | im not sure about with the USB | 16:53 |
| zylogz80 | holstein, what do you use for an interface? | 16:53 |
| holstein | you shoud be able to get 5 or so though | 16:53 |
| holstein | stable | 16:53 |
| zylogz80 | holstein, yeah 5-6 would be more than great coming from almost 50 | 16:54 |
| holstein | presonus firepod | 16:54 |
| holstein | http://www.presonus.com/products/detail.aspx?productid=3 | 16:54 |
| holstein | zylogz80: if you use abogani's PPA, the RT kernel is called linux-realtime | 16:54 |
| holstein | zylogz80: you might also benefit from | 16:55 |
| holstein | https://launchpad.net/~falk-t-j/+archive/lucid/ | 16:55 |
| zylogz80 | holstein, cool looking peice of gear. I'd need to get a firewire express card interface or something | 16:55 |
| holstein | ^^ some of the stuff in falks ppa | 16:55 |
| holstein | JACK2 | 16:55 |
| holstein | from what i read | 16:55 |
| holstein | utilizes multiple cores | 16:56 |
| holstein | zylogz80: IF you get a firewire card | 16:56 |
| zylogz80 | holstein, interesting | 16:56 |
| holstein | try and get a texas instruments chipset | 16:56 |
| holstein | OR save the recipts ;) | 16:56 |
| zylogz80 | holstein, thanks for the tips. I really appreciate the help. These ppas look interesting | 16:57 |
| holstein | zylogz80: i use http://ubuntu-tweak.com/ | 16:57 |
| holstein | there is a PPA purge option added | 16:58 |
| holstein | SO if you get falks ppa going | 16:58 |
| holstein | and it borks something | 16:58 |
| holstein | you can get out | 16:58 |
| holstein | he's got abogani's kernels in there too | 16:58 |
| holstein | zylogz80: there are a bunch of KXstudio specific packages in there that i would avoid | 16:58 |
| holstein | other than that, i think its safe to add the PPA | 16:59 |
| zylogz80 | holstein, cool. yeah I would be looking mostly at the realtime kernel and some soundfonts for qsynth | 16:59 |
| holstein | and do an upgrade | 16:59 |
| zylogz80 | holstein, ubuntu tweak looks really helpful | 16:59 |
| holstein | i started using it for PPA purge | 17:00 |
| holstein | but some of the gconf tweaking is easier to find with it | 17:00 |
| zylogz80 | holstein, so if I mess something up it'll remove all the packages I installed form that ppa? | 17:00 |
| holstein | zylogz80: you just open tweak | 17:00 |
| holstein | and say 'purge PPA' | 17:00 |
| holstein | and it'll remove what you installed from that PPA | 17:01 |
| holstein | and downgrade whatever needs to be downgraded | 17:01 |
| * holstein tested | 17:01 | |
| holstein | with that PPA acutally | 17:01 |
| holstein | i tested on my laptop | 17:01 |
| zylogz80 | holstein, very cool. ubuntu tweak seems really neat | 17:01 |
| holstein | before doing it on my main studio machine | 17:01 |
| holstein | i wanted to make sure there was an 'easy' way back to JACK 1 | 17:02 |
| zylogz80 | holstein, I've got great backups and I may test in a virtual machine first just to make sure I understand the process | 17:02 |
| holstein | zylogz80: i totally understand that | 17:02 |
| holstein | i just wanted to let you know that its pretty much 'safe' | 17:03 |
| holstein | and that i have tested it | 17:03 |
| holstein | but i would do the same :) | 17:03 |
| zylogz80 | holstein, thanks very much. you've given me a whole bunch of leads to chase down. I really apprecieate it. | 17:04 |
| zylogz80 | holstein, I'll check if you're on later and let you know how everything panned out | 17:04 |
| holstein | zylogz80: OH | 17:04 |
| holstein | and one more | 17:04 |
| holstein | #opensourcemusicians | 17:04 |
| holstein | very helpful folk :) | 17:05 |
| holstein | zylogz80: good luck | 17:05 |
| zylogz80 | holstein, thanks! | 17:05 |
| ronj | hi there | 17:16 |
| ronj | today'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 |
| holstein | ronj: i think its already there ?? | 17:19 |
| holstein | its known | 17:19 |
| holstein | ronj: are you on the email list? | 17:19 |
| ronj | holstein, ok; didn't know | 17:19 |
| holstein | you might want to send an email there so its documented | 17:19 |
| holstein | but it was yesterday or the day before i say some talk about hat | 17:20 |
| holstein | that* | 17:20 |
| ronj | holstein, 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 :P | 17:20 |
| ronj | ok | 17:20 |
| ronj | thanks! | 17:20 |
| holstein | ronj: HEY | 17:20 |
| holstein | thats great :) | 17:20 |
| holstein | iso testing is greatly appreciated | 17:21 |
| ronj | holstein, were you mentioning the user of devel list? | 17:23 |
| holstein | ronj: i think devel would be appropriate | 17:24 |
| holstein | you can ask over in ubuntustudio-devel too | 17:24 |
| ronj | right | 17:24 |
| prep | Brasero is not burning correctly, ejects disc when trying to burn, just started recently | 18:41 |
| holstein | bad discs? | 18:41 |
| prep | Nope, was burning ok last time I burned last week, just started | 18:42 |
| * holstein is using gnomebaker | 18:42 | |
| holstein | prep: i would try and rule out hardware and discs | 18:42 |
| holstein | maybe use a live CD | 18:43 |
| holstein | and try burning something | 18:43 |
| holstein | or use a different optical drive | 18:43 |
| prep | Used 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 blank | 18:43 |
| holstein | what is 'built in cd/dvd creator' software? | 18:44 |
| holstein | brasero? | 18:44 |
| prep | No, another one. Not at the PC at the moment, not sure the exact name. Came with the distro | 18:45 |
| holstein | so | 18:45 |
| holstein | you have tried 2 different pieces of software | 18:45 |
| holstein | in the same linux distro | 18:45 |
| holstein | i would probably install gnomebaker | 18:46 |
| holstein | and then, try burning from a live CD | 18:46 |
| holstein | then, i would start thinking its hardware | 18:46 |
| holstein | i got a stack of bad optical drives :) | 18:46 |
| holstein | they die | 18:46 |
| prep | weird it just started. Was burning fine | 18:46 |
| prep | was thinking maybe a software conflict | 18:47 |
| holstein | yup | 18:47 |
| holstein | when my LG died | 18:47 |
| holstein | that how it went | 18:47 |
| holstein | but LG replaced it :) | 18:47 |
| prep | When 10.10 is out, i'm staying put | 18:47 |
| holstein | prep: probably not going to have a software conflict | 18:47 |
| holstein | if you stay pretty much in the repo | 18:47 |
| holstein | things are pretty well tested | 18:47 |
| holstein | OH | 18:48 |
| holstein | yeah, it could be a maverick thing | 18:48 |
| prep | yeah haven't added any disc burn software | 18:48 |
| holstein | i would try a lucid live disc | 18:48 |
| prep | yeah dont forget I'm a Maverick cripple | 18:48 |
| holstein | hehe | 18:48 |
| holstein | now you know | 18:48 |
| prep | aight, at work. I'm out. Be easy | 18:48 |
| holstein | prep: laterx | 18:49 |
| prep | we'll try to troubleshoot it tomorrow. . | 18:49 |
