astrodonAnyone know what the deal is with low-latency kernel?01:24
astrodonWill it keep up with the regular kernel updates?01:25
_ravenhi09:15
_ravendo you know about any jingle player/cartwall? which tool would be nice?09:15
_ravenanyone here?10:24
tycheSure, there's people here.  That doesn't necessarily mean that we know the answer to your question.10:27
_raventyche i just need any midi sampler, which i easily can drag sounds on and which plays theese sounds by midi keyboard or by function keys10:41
ailo_raven: If you need a drum sampler, try hydrogen11:57
ailoThen there's specimen, and petri-foo11:57
ailolinux-sampler is a full fledged sampler, which you can get with one of the kxstudio PPA's11:58
ailoI sometimes have problems with its' frontend, qsampler though11:58
ailoI hear Rui, who coded qtractor and qjackctl is working on a simple sampler instrument too11:59
ailoThat should be worth the wait11:59
ailoI'm working on a sampler for puredata, which I will publish sometime this summer12:00
_ravenailo ok tnx for the hint12:14
lamalexhey guys, anyone know if presonus firestudio works?15:47
MaynardWatershey guys, I was trying to work with python bindings for PortAudio, and I ran into some trouble17:58
MaynardWatershttp://pastebin.com/1wwpJrtF18:00
MaynardWatersany help is welcomed18:00
MaynardWatersbrb18:00
MaynardWatersfigured it out, simple uninstall and reinstall appears to have worked.18:34
_eeinhello, does anyone have an m-audio 1010lt working under studio 12.04?19:18
_eeinim on  a live boot and not sure if i should just remove PA and use ALSA?19:18
len-dt_eein, The m-audio envy24 cards should work just fine19:45
_eeinlen-dt, it works but i dont see how to select outputs or inputs19:46
len-dt_eein, I use the D66 and it worked for me19:46
len-dtUse mudita2419:47
_eeini was i see nothing in that to choose the default out for audio19:47
len-dtIt will give you a nice mixer app. You can select in/out with jack but pulse tends to just use the first two19:47
len-dtDo you have internal sound as well?19:48
_eeinlen-dt, which is what i dont want, i dont want the first two.  internal is diwsabled in BIOS19:48
_eeinalso how would you pick which inputs record on?19:49
len-dtIf you start jack, pulse will show jack sink with all the outputs19:49
len-dtto record use jack.19:49
len-dtThere is qjackctl in the audio production menu19:49
_eein19:50:21.274 D-BUS: JACK server could not be started. Sorry19:50
_eeinCannot connect to server socket err = No such file or directory19:50
_eeinCannot connect to server socket19:50
_eeinjack server is not running or cannot be started19:50
len-dtWhen you start jack from there, you should be able to see all your inputs with the connect button19:50
len-dtHave you tried clicking the start button anyway?19:51
_eeinyes thats the error19:51
len-dtHow have you got it set up?19:51
_eeinits at default setup19:52
len-dtopen the setup and at the interface click on the ">"19:53
len-dtyou should see one at least that says M-Audio19:54
_eeinyes hw:0 and hw:0,0 ice171219:58
_eeinlen-dt, switched interface from default to hw:0 still errors when starting19:59

len-dt_eein, Hmm, I have never had that problem.. however, it may be help ful to turn it off in pulse.20:01
len-dtAt the top of the screen there is a little "speaker" icon20:01
len-dtIf you click on that and select sound settings, pavucontrol will open20:01
len-dtThe last tab on the right  should show your ice card and allow you to select off.20:02
_eeinyes in it20:03
len-dtThen try again with jack.20:03
_eeinwhich tab? i got mute set as fallback20:04
_eeinand lock channels20:05
len-dtThe configuration tab20:05
_eeinahh nm the drop down20:05
len-dtMine says ice171220:05
len-dtYou can set the profile to "off"20:06
_eeinlen-dt, same errors20:07
_eeinhttp://pastebin.com/sTm8LdxL20:07
len-dtOk, one more try that I can think of... open a terminal20:07
_eeinat one20:08
len-dtI should have said quit qjackctl20:09
len-dtthen restart it as root: sudo qjackctl20:09
_eein:-) doh yeah that works20:09
len-dtHmm thats bad.20:10
len-dtIt should not require root priv.20:10
len-dtI have never had that on the live dvd.20:10
len-dtdid you create a new acount?20:10
_eeinno20:11
_eeinbut ive been messing around, letme restart20:12
_eeinlen-dt, ok brand new seup20:18
argeshello. Is there an easy way to get the current XRUN count for jack via the command line?20:18
len-dt_eein, your user should be in the audio group and the file /etc/security/limit.d/audio.conf should exist.20:21
_eeincat: /etc/security/limit.d/audio.conf: No such file or directory20:21
len-dt_eein, is it called audio.conf.disabled by chance?20:22
_eein/etc/security/limits.d$ ls20:22
_eeinaudio.conf20:22
* _eein shrugs well its there 20:22
len-dtDoes jack work this time?]20:23
_eeinyes20:23
len-dtarges, there are a lot of jack_* utils. I don't know if one of them would help or not.20:23
argeslen-dt, yea i've been going through those20:23
len-dt_eein,  I wonder what happened last time20:24
_eeinlen-dt, but in the patchbay there are no devices to add20:24
* _eein shrugs 20:24
len-dtarges, the only one I have used is jack_control.20:24
len-dt_eein, Not patchbay20:24
len-dtConections20:24
_eeinok in Connect there is nothing either except under MIDI20:25
_eeinerr rather the ALSA tab20:25
len-dt_eein, Then jack is not running yet20:25
_eeinok i refreshed and it populated20:26
len-dt_eein, click the triangle next to system]20:26
_eeinbut its setup as a surround dound20:26
len-dtYou should see your inputs... not in pulse. Pulse thinks suround20:27
len-dtIf you start a recorder it should show up in jack20:28
_eeinhttp://imagebin.org/21891120:28
len-dtYa, that is just the pulse/jack bridge, it can safely be ignored20:29
len-dtWhat program do you want to record with? Ustudio comes with audacity and ardour20:29
len-dt_eein, if you want to get pulse out of the way you can do a "Disconnect all"20:32
_eeinok i have my dj mixer outputing music and going into the 3/4 inputs on my card i opened audacity and pressed record and the progress bar is stuck at 0 and no signal20:32
len-dt_eein, Do you see audacity on the jack audio connect pannel?20:33
len-dtIn audacity _eein you will need to go edit->preferences and change host to jack20:34
_eeinerror while opening sound device please check the input device settings and the project sample rate20:34
_eeinlen-dt,20:36
len-dtWhen did you get that? Audacity will not open the input sound device till you hit record.20:36
_eeinhttp://imagebin.org/21891220:36
_eeinwhen i hit record i get that20:36
len-dtDid you get that from jack or audacity?20:37
_eeinaudacity20:38
len-dtTo set levels in audacity, I normally hit pause first then record.20:38
_eeinsame error20:38
len-dtI don't but then I am running the installed version not the live dvd.20:38
len-dtAre you running from a dvd or a USB stick?20:39
_eeinusb20:40
len-dtUSB normally works better, that is how I did all my testing.20:40
_eeinis my playback and recording settigns for audacity suppose to be PulseAudio JACK sink or system?20:40
_eeinyeah i dont even buy optical media anymore20:41
len-dtIn the connect panel, audacity will show a portaudio20:41
len-dtIn may case it is already conected to capture 1 and 220:41
len-dt(under system)20:41
len-dtI must have something plugged into chanel one because I see noise in the left channel of audacity.20:42
_eeinwhat connect panel?20:43
* len-dt finds a guitar plaugged in20:43
len-dtThe jack connect pannel20:43
ailolamalex: http://ffado.org/?q=devicesupport%2Flist&filter0=Presonus&filter1=&op2=OR20:43
ailolamalex: Some devices may work, even if they aren't listed. Partially, or otherwise20:43
ailolamalex: I recommend contacting the ffado devs, if you are unsure20:44
ailoI mean, on their user mail list for instance20:44
_eeinlen-dt, my JACK connect panel hasnt changed after opening audacity from the pic i linked20:44
ailolamalex: Ah, sorry. Looks like it says not supported :(20:44
ailolamalex: So, that would probably mean no20:44
lamalexyah, i found that earlier- thanks though20:45
len-dtIt will only show if you are in record mode... which is not working for you :(20:45
_eeinwhat do you have set in devices for audacity20:45
ailolamalex: You already have that device?20:45
lamalexno not yet20:45
lamalexbut i think after today's research im just going to ditch recording on linux and use logic pro.20:45
ailolamalex: I have a focusrite pro 40. Works really well.20:46
len-dt_eein, where in audacity do you find devices?20:47
_eeinpreferences20:47
ailolamalex: Oh yeah :)? Well, I'm sure you can do without it to some degree, but you'll probably miss all the fancy instruments20:47
len-dtI just have system20:47
lamalexailo, hm?20:47
lamalexmy guitar is sort of platform agnostic :p20:47
ailolamalex: I mean, you can do recording and midi sequencing quite well on Linux based systems. You can even use vst plugins on some systems. But you won't be able to use software instruments like those available to Logic Pro20:48
len-dt_eein, I have system on both record and playback20:48
ailoAnyway, there's also the matter of what is free and not20:49
ailoIf that is an issue20:49
lamalexailo, yar, i'm just doing recording anyway. i dont have a lot of interest in midi sequencing and such20:49
_eeinlen-dt, i got it to record without recording anything  see screenshot http://imagebin.org/21891320:49
ailolamalex: Then I recommend you try out Ardour. It works on Mac as well. It isn't as fancy looking as Logic Pro, but it's a real recording/mixing system. Soon to be released: Ardour 3.20:50
ailoArdour3 Beta is available20:50
lamalexailo, yah i own a copy of mixbus actually20:50
ailoAha. Yeah, I just got it myself earileri20:50
ailoearlier..20:50
ailolamalex: So, what's stopping you from using Linux?20:51
len-dt_eein, the only problem is that you are trying to record from pulse audio, you want to record from system20:51
lamalexwell i lost my board which i was using for its pres and then running the directs to a delta 1010 card into mixbux. this was fine, but i lost my board- so i'd need a new one or a digital interface20:51
ailolamalex: There's one usb device which seems to work really well..20:52
lamalexyah but then you've got to worry about USB synchonicity and stuff20:52
lamalexfirewire is just better suited to handle audio data20:52
_eeinlen-dt, ok i switched it back to system and relaunched audacity  see screenshot http://imagebin.org/21891420:52
ailolamalex: If you prefer firewire, you have more choices I would say20:52
lamalexi mean the work arounds are ok but the other advantage to FW is daisychainging20:53
_eeinlen-dt, still dont get any audio waveform in audacity20:53
lamalexso when i need more pre's i can just daisy chain instead of having to get a who new usb card to keep my two interfaces off of the same IRQ and getting dropouts :P20:53
* lamalex wishes he could just afford 2" tape..20:53
_eeinlen-dt, i have 3/4 input all the way up in envy2420:53
ailolamalex: daisychaining should work, if you sync the cards with spdif. I have got no other confirmation on having successful daisychaining20:53
ailolamalex: On Linux, I mean20:54
len-dt_eein, maybe you should connect your port audio 34 to capture 3/4 too20:54
ailolamalex: That was a major reason for me choosing focusrite 40 Pro, so that I could expand it with ADAT, if nothing else worked20:54
len-dt_eein, your picture shows port audio connected to 1 and 220:54
ailolamalex: Firewire works really well on Linux, as long as you don't have hardware issues with irq's and stuff, which you already seem to be aware of.20:55
_eeinlen-dt, yeah ok still no change20:55
len-dt_eein, click on port audio in_3 and capture_1 then the disconnect button20:55
ailolamalex: Latecnies down to under 1ms within the system, if you're lucky20:56
len-dt_eein, in mudta24 in monitor inputs do you see any level?20:57
_eeinlen-dt, no20:57
_eeinlen-dt, yeah i disconnected the 1/2 as well20:57
_eeinlen-dt, http://imagebin.org/21891520:57
len-dt_eein, mudita 24 in analogue volume are the adcs turned up?20:57
_eeinnot sure why they say off20:58
_eeindoh i had 3/4 DAC not ADC on20:59
* _eein face palm20:59
len-dt_eein, I learned that way too20:59
ailo_eein: That's how I started out on Linux too :)20:59
ailo_eein: With the same kind of device20:59
_eeinits a lesson in humility21:00
ailo_eein: I explain a bit about this here https://help.ubuntu.com/community/UbuntuStudio/ProAudioIntro/120421:00
_eeinthanks for all the help21:00
ailoIt's an  intro to audio on Ubuntu Studio21:00
len-dt_eein, no problen21:00
_eeinlen-dt, it doesnt look like there is a way to bond ADC 3/4 together is there in envy24?21:01
len-dtDo you mean levels?21:01
ailo_eein: Nope. You need to set them individually21:02
len-dt_eein, they do have a number at the bottom so you can make them the same21:02
ailo_eein: Select it and use your keyboard up and down keys to set it exactly21:02
_eeinyeah i have them set the same just was hoping i could bond them21:03
len-dt_eein, once you have set them they are generally left at the same setting anyway.21:04
len-dt_eein, unless you try recording with pulse... pulse may change them for you :(21:05
ailoI don't think it can, can it?21:05
ailoOnly on some devices21:06
len-dtNot sure about the ice, but it does with my HDA21:06
_eeinhmmm if i stop the recording and press again it switches the PortAudio in JACK conenctions21:06
ailoWhere the hardware and software level is the same21:06
_eeinso now the PortAudio is 5/6 then 7/821:06
_eeinnot really sure what PortAudio means in JACK Connections21:07
len-dt_eein, That is audacity. I think most people use ardour for anything more complex than recording once.21:07
len-dt_eein, portaudio is the interface library audacity uses to connect to jack21:07
_eeinyeah reading....but it also defaulted to Capture 1 & 2 how do i keep 3 & 421:08
len-dt_eein, so when recording the sound goes IF->alsa->jack->portaudio->audacity.21:09
ailo_eein: Audacity uses some portaudio in it's own audio engine. Not related to jack21:09
ailoNo, the portaudio ports should be the Audacity inputs and outputs21:09
_eeinyeah but it defaults to the wrong inputs21:10
_eeinonce i stop recording and record again the PortAudios match to Connect_1 and Connect_221:10
ailo_eein: You need to set up a patchbay profile21:10
_eeinrather Capture_1 Capture_221:10
ailo_eein: I assume you are using qjackctl21:10
_eeinyes21:11
ailo_eein: Since Audacity is not being connected all the time, you need to have it running while you create the profile21:12
ailoSo, make sure you are playing a long file21:12
lamalexailo, dang this focusrite 40 has phantom on every channel + pads? very nice. this honestly looks like the nicest interface ive seen so far21:12
ailolamalex: The preamps probably aren't the best in the world, but that was not a concern of mine. There should be similar firepods too21:13
ailolamalex: I did feel the focusrite had the specs and the price range I was looking for21:13
len-dtailo, I think he is more interested in recording, pause then record.21:14
ailolen-dt: I understand, but he wants to maintain the connection he chooses21:14
ailoAnd for that he needs to set up a profile in patchbay21:14
len-dtailo, yup21:14
ailoEach time you start any application that has connections set in the profile, they will connect the same way each time21:14
lamalexailo, what's not so good about them? are they noisy?21:15
lamalexsoundonsound seems to think they're nicer than the m-audio ones at least21:15
ailolamalex: Nope. They are fine. I don't think you can find better preamps in that price range21:16
ailoThe gain is a bit low on the mic pre's but no noise21:16
ailo_eein: What you do is you click "add" for each input and output you want to have presistent connections for21:17
lamalexsoundonsound claims higher gain than the m-audio 2626, so maybe low gain is just a problem for this price range in general :P21:17
ailolamalex: Could be. The gain was a bit lower than I was used to on mixer boards anyway21:18
lamalexah yah i can imagine that being the case21:18
ailoHaving to turn up a bit over half for vocals, which would be half normally21:18
lamalexsounds like you still had ample headroom though21:18
lamalexdoes jack work well with routing on this?21:18
ailolamalex: jack is the only thing you can use with it. As for routing, jack is king21:19
ailoSince you can connect any app to any app, etc21:19
lamalexindeed, i guess i was trying to compare it's windows based routing software vs jack21:19
ailolamalex: Oh. The internal routing is done with ffado-mixer21:19
lamalexahh ok21:20
lamalexso does /that/ work well here21:20
ailolamalex: It's a generic firewire mixer for ffado devices. It had a bug for focusrite a while back, and I don't know on the back of my hand when they solved it, but it should work pretty well now21:20
ailoI actually muted all inputs and outputs during a live session when using ffado-mixer half a year ago. Needed to reset with a mac later21:21
ailoThat problem should have gone away, if not with current Ubuntu Studio, then at least with the next upcoming release21:21
ailoBeen a while since I used it. I keep all inputs and outputs just as ins and outs. No monitoring. I do all of that with software21:22
ailoOtherwise, the internal mixer is quite usable21:22
ailo_eein: I just noticed you could do this: Start audacity. Make the connections you want. Go to patchbay while Audacity is running. Click "New"21:24
ailo_eein: That should create a routing scheme with all the connections you are currently using21:24
ailo_eein: And all you need to do after that is keep that profile active, to have persistent connections21:24
ailolamalex: I do know the ffado people solved the bug earlier this year. The only matter is whether that version of ffado was included with Ubuntu Studio 12.04, or will be on next release (which is for sure it will be)21:27
