[01:24] <astrodon> Anyone know what the deal is with low-latency kernel?
[01:25] <astrodon> Will it keep up with the regular kernel updates?
[09:15] <_raven> hi
[09:15] <_raven> do you know about any jingle player/cartwall? which tool would be nice?
[10:24] <_raven> anyone here?
[10:27] <tyche> Sure, there's people here.  That doesn't necessarily mean that we know the answer to your question.
[10:41] <_raven> tyche i just need any midi sampler, which i easily can drag sounds on and which plays theese sounds by midi keyboard or by function keys
[11:57] <ailo> _raven: If you need a drum sampler, try hydrogen
[11:57] <ailo> Then there's specimen, and petri-foo
[11:58] <ailo> linux-sampler is a full fledged sampler, which you can get with one of the kxstudio PPA's
[11:58] <ailo> I sometimes have problems with its' frontend, qsampler though
[11:59] <ailo> I hear Rui, who coded qtractor and qjackctl is working on a simple sampler instrument too
[11:59] <ailo> That should be worth the wait
[12:00] <ailo> I'm working on a sampler for puredata, which I will publish sometime this summer
[12:14] <_raven> ailo ok tnx for the hint
[15:47] <lamalex> hey guys, anyone know if presonus firestudio works?
[17:58] <MaynardWaters> hey guys, I was trying to work with python bindings for PortAudio, and I ran into some trouble
[18:00] <MaynardWaters> http://pastebin.com/1wwpJrtF
[18:00] <MaynardWaters> any help is welcomed
[18:00] <MaynardWaters> brb
[18:34] <MaynardWaters> figured it out, simple uninstall and reinstall appears to have worked.
[19:18] <_eein> hello, does anyone have an m-audio 1010lt working under studio 12.04?
[19:18] <_eein> im on  a live boot and not sure if i should just remove PA and use ALSA?
[19:45] <len-dt> _eein, The m-audio envy24 cards should work just fine
[19:46] <_eein> len-dt, it works but i dont see how to select outputs or inputs
[19:46] <len-dt> _eein, I use the D66 and it worked for me
[19:47] <len-dt> Use mudita24
[19:47] <_eein> i was i see nothing in that to choose the default out for audio
[19:47] <len-dt> It will give you a nice mixer app. You can select in/out with jack but pulse tends to just use the first two
[19:48] <len-dt> Do you have internal sound as well?
[19:48] <_eein> len-dt, which is what i dont want, i dont want the first two.  internal is diwsabled in BIOS
[19:49] <_eein> also how would you pick which inputs record on?
[19:49] <len-dt> If you start jack, pulse will show jack sink with all the outputs
[19:49] <len-dt> to record use jack.
[19:49] <len-dt> There is qjackctl in the audio production menu
[19:50] <_eein> 19:50:21.274 D-BUS: JACK server could not be started. Sorry
[19:50] <_eein> Cannot connect to server socket err = No such file or directory
[19:50] <_eein> Cannot connect to server socket
[19:50] <_eein> jack server is not running or cannot be started
[19:50] <len-dt> When you start jack from there, you should be able to see all your inputs with the connect button
[19:51] <len-dt> Have you tried clicking the start button anyway?
[19:51] <_eein> yes thats the error
[19:51] <len-dt> How have you got it set up?
[19:52] <_eein> its at default setup
[19:53] <len-dt> open the setup and at the interface click on the ">"
[19:54] <len-dt> you should see one at least that says M-Audio
[19:58] <_eein> yes hw:0 and hw:0,0 ice1712
[19:59] <_eein> len-dt, switched interface from default to hw:0 still errors when starting

[20:01] <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-dt> At the top of the screen there is a little "speaker" icon
[20:01] <len-dt> If you click on that and select sound settings, pavucontrol will open
[20:02] <len-dt> The last tab on the right  should show your ice card and allow you to select off.
[20:03] <_eein> yes in it
[20:03] <len-dt> Then try again with jack.
[20:04] <_eein> which tab? i got mute set as fallback
[20:05] <_eein> and lock channels
[20:05] <len-dt> The configuration tab
[20:05] <_eein> ahh nm the drop down
[20:05] <len-dt> Mine says ice1712
[20:06] <len-dt> You can set the profile to "off"
[20:07] <_eein> len-dt, same errors
[20:07] <_eein> http://pastebin.com/sTm8LdxL
[20:07] <len-dt> Ok, one more try that I can think of... open a terminal
[20:08] <_eein> at one
[20:09] <len-dt> I should have said quit qjackctl
[20:09] <len-dt> then restart it as root: sudo qjackctl
[20:09] <_eein> :-) doh yeah that works
[20:10] <len-dt> Hmm thats bad.
[20:10] <len-dt> It should not require root priv.
[20:10] <len-dt> I have never had that on the live dvd.
[20:10] <len-dt> did you create a new acount?
[20:11] <_eein> no
[20:12] <_eein> but ive been messing around, letme restart
[20:18] <_eein> len-dt, ok brand new seup
[20:18] <arges> hello. Is there an easy way to get the current XRUN count for jack via the command line?
[20:21] <len-dt> _eein, your user should be in the audio group and the file /etc/security/limit.d/audio.conf should exist.
[20:21] <_eein> cat: /etc/security/limit.d/audio.conf: No such file or directory
[20:22] <len-dt> _eein, is it called audio.conf.disabled by chance?
[20:22] <_eein> /etc/security/limits.d$ ls
[20:22] <_eein> audio.conf
[20:22]  * _eein shrugs well its there 
[20:23] <len-dt> Does jack work this time?]
[20:23] <_eein> yes
[20:23] <len-dt> arges, there are a lot of jack_* utils. I don't know if one of them would help or not.
[20:23] <arges> len-dt, yea i've been going through those
[20:24] <len-dt> _eein,  I wonder what happened last time
[20:24] <_eein> len-dt, but in the patchbay there are no devices to add
[20:24]  * _eein shrugs 
[20:24] <len-dt> arges, the only one I have used is jack_control.
[20:24] <len-dt> _eein, Not patchbay
[20:24] <len-dt> Conections
[20:25] <_eein> ok in Connect there is nothing either except under MIDI
[20:25] <_eein> err rather the ALSA tab
[20:25] <len-dt> _eein, Then jack is not running yet
[20:26] <_eein> ok i refreshed and it populated
[20:26] <len-dt> _eein, click the triangle next to system]
[20:26] <_eein> but its setup as a surround dound
[20:27] <len-dt> You should see your inputs... not in pulse. Pulse thinks suround
[20:28] <len-dt> If you start a recorder it should show up in jack
[20:28] <_eein> http://imagebin.org/218911
[20:29] <len-dt> Ya, that is just the pulse/jack bridge, it can safely be ignored
[20:29] <len-dt> What program do you want to record with? Ustudio comes with audacity and ardour
[20:32] <len-dt> _eein, if you want to get pulse out of the way you can do a "Disconnect all"
[20:32] <_eein> ok 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 signal
[20:33] <len-dt> _eein, Do you see audacity on the jack audio connect pannel?
[20:34] <len-dt> In audacity _eein you will need to go edit->preferences and change host to jack
[20:34] <_eein> error while opening sound device please check the input device settings and the project sample rate
[20:36] <_eein> len-dt,
[20:36] <len-dt> When did you get that? Audacity will not open the input sound device till you hit record.
[20:36] <_eein> http://imagebin.org/218912
[20:36] <_eein> when i hit record i get that
[20:37] <len-dt> Did you get that from jack or audacity?
[20:38] <_eein> audacity
[20:38] <len-dt> To set levels in audacity, I normally hit pause first then record.
[20:38] <_eein> same error
[20:38] <len-dt> I don't but then I am running the installed version not the live dvd.
[20:39] <len-dt> Are you running from a dvd or a USB stick?
[20:40] <_eein> usb
[20:40] <len-dt> USB normally works better, that is how I did all my testing.
[20:40] <_eein> is my playback and recording settigns for audacity suppose to be PulseAudio JACK sink or system?
[20:41] <_eein> yeah i dont even buy optical media anymore
[20:41] <len-dt> In the connect panel, audacity will show a portaudio
[20:41] <len-dt> In may case it is already conected to capture 1 and 2
[20:41] <len-dt> (under system)
[20:42] <len-dt> I must have something plugged into chanel one because I see noise in the left channel of audacity.
[20:43] <_eein> what connect panel?
[20:43]  * len-dt finds a guitar plaugged in
[20:43] <len-dt> The jack connect pannel
[20:43] <ailo> lamalex: http://ffado.org/?q=devicesupport%2Flist&filter0=Presonus&filter1=&op2=OR
[20:43] <ailo> lamalex: Some devices may work, even if they aren't listed. Partially, or otherwise
[20:44] <ailo> lamalex: I recommend contacting the ffado devs, if you are unsure
[20:44] <ailo> I mean, on their user mail list for instance
[20:44] <_eein> len-dt, my JACK connect panel hasnt changed after opening audacity from the pic i linked
[20:44] <ailo> lamalex: Ah, sorry. Looks like it says not supported :(
[20:44] <ailo> lamalex: So, that would probably mean no
[20:45] <lamalex> yah, i found that earlier- thanks though
[20:45] <len-dt> It will only show if you are in record mode... which is not working for you :(
[20:45] <_eein> what do you have set in devices for audacity
[20:45] <ailo> lamalex: You already have that device?
[20:45] <lamalex> no not yet
[20:45] <lamalex> but i think after today's research im just going to ditch recording on linux and use logic pro.
[20:46] <ailo> lamalex: I have a focusrite pro 40. Works really well.
[20:47] <len-dt> _eein, where in audacity do you find devices?
[20:47] <_eein> preferences
[20:47] <ailo> lamalex: Oh yeah :)? Well, I'm sure you can do without it to some degree, but you'll probably miss all the fancy instruments
[20:47] <len-dt> I just have system
[20:47] <lamalex> ailo, hm?
[20:47] <lamalex> my guitar is sort of platform agnostic :p
[20:48] <ailo> lamalex: 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 Pro
[20:48] <len-dt> _eein, I have system on both record and playback
[20:49] <ailo> Anyway, there's also the matter of what is free and not
[20:49] <ailo> If that is an issue
[20:49] <lamalex> ailo, yar, i'm just doing recording anyway. i dont have a lot of interest in midi sequencing and such
[20:49] <_eein> len-dt, i got it to record without recording anything  see screenshot http://imagebin.org/218913
[20:50] <ailo> lamalex: 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] <ailo> Ardour3 Beta is available
[20:50] <lamalex> ailo, yah i own a copy of mixbus actually
[20:50] <ailo> Aha. Yeah, I just got it myself earileri
[20:50] <ailo> earlier..
[20:51] <ailo> lamalex: 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 system
[20:51] <lamalex> well 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 interface
[20:52] <ailo> lamalex: There's one usb device which seems to work really well..
[20:52] <lamalex> yah but then you've got to worry about USB synchonicity and stuff
[20:52] <lamalex> firewire is just better suited to handle audio data
[20:52] <_eein> len-dt, ok i switched it back to system and relaunched audacity  see screenshot http://imagebin.org/218914
[20:52] <ailo> lamalex: If you prefer firewire, you have more choices I would say
[20:53] <lamalex> i mean the work arounds are ok but the other advantage to FW is daisychainging
[20:53] <_eein> len-dt, still dont get any audio waveform in audacity
[20:53] <lamalex> so 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 :P
[20:53]  * lamalex wishes he could just afford 2" tape..
[20:53] <_eein> len-dt, i have 3/4 input all the way up in envy24
[20:53] <ailo> lamalex: daisychaining should work, if you sync the cards with spdif. I have got no other confirmation on having successful daisychaining
[20:54] <ailo> lamalex: On Linux, I mean
[20:54] <len-dt> _eein, maybe you should connect your port audio 34 to capture 3/4 too
[20:54] <ailo> lamalex: That was a major reason for me choosing focusrite 40 Pro, so that I could expand it with ADAT, if nothing else worked
[20:54] <len-dt> _eein, your picture shows port audio connected to 1 and 2
[20:55] <ailo> lamalex: 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] <_eein> len-dt, yeah ok still no change
[20:55] <len-dt> _eein, click on port audio in_3 and capture_1 then the disconnect button
[20:56] <ailo> lamalex: Latecnies down to under 1ms within the system, if you're lucky
[20:57] <len-dt> _eein, in mudta24 in monitor inputs do you see any level?
[20:57] <_eein> len-dt, no
[20:57] <_eein> len-dt, yeah i disconnected the 1/2 as well
[20:57] <_eein> len-dt, http://imagebin.org/218915
[20:57] <len-dt> _eein, mudita 24 in analogue volume are the adcs turned up?
[20:58] <_eein> not sure why they say off
[20:59] <_eein> doh i had 3/4 DAC not ADC on
[20:59]  * _eein face palm
[20:59] <len-dt> _eein, I learned that way too
[20:59] <ailo> _eein: That's how I started out on Linux too :)
[20:59] <ailo> _eein: With the same kind of device
[21:00] <_eein> its a lesson in humility
[21:00] <ailo> _eein: I explain a bit about this here https://help.ubuntu.com/community/UbuntuStudio/ProAudioIntro/1204
[21:00] <_eein> thanks for all the help
[21:00] <ailo> It's an  intro to audio on Ubuntu Studio
[21:00] <len-dt> _eein, no problen
[21:01] <_eein> len-dt, it doesnt look like there is a way to bond ADC 3/4 together is there in envy24?
[21:01] <len-dt> Do you mean levels?
[21:02] <ailo> _eein: Nope. You need to set them individually
[21:02] <len-dt> _eein, they do have a number at the bottom so you can make them the same
[21:02] <ailo> _eein: Select it and use your keyboard up and down keys to set it exactly
[21:03] <_eein> yeah i have them set the same just was hoping i could bond them
[21:04] <len-dt> _eein, once you have set them they are generally left at the same setting anyway.
[21:05] <len-dt> _eein, unless you try recording with pulse... pulse may change them for you :(
[21:05] <ailo> I don't think it can, can it?
[21:06] <ailo> Only on some devices
[21:06] <len-dt> Not sure about the ice, but it does with my HDA
[21:06] <_eein> hmmm if i stop the recording and press again it switches the PortAudio in JACK conenctions
[21:06] <ailo> Where the hardware and software level is the same
[21:06] <_eein> so now the PortAudio is 5/6 then 7/8
[21:07] <_eein> not really sure what PortAudio means in JACK Connections
[21:07] <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 jack
[21:08] <_eein> yeah reading....but it also defaulted to Capture 1 & 2 how do i keep 3 & 4
[21:09] <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 jack
[21:09] <ailo> No, the portaudio ports should be the Audacity inputs and outputs
[21:10] <_eein> yeah but it defaults to the wrong inputs
[21:10] <_eein> once i stop recording and record again the PortAudios match to Connect_1 and Connect_2
[21:10] <ailo> _eein: You need to set up a patchbay profile
[21:10] <_eein> rather Capture_1 Capture_2
[21:10] <ailo> _eein: I assume you are using qjackctl
[21:11] <_eein> yes
[21:12] <ailo> _eein: Since Audacity is not being connected all the time, you need to have it running while you create the profile
[21:12] <ailo> So, make sure you are playing a long file
[21:12] <lamalex> ailo, dang this focusrite 40 has phantom on every channel + pads? very nice. this honestly looks like the nicest interface ive seen so far
[21:13] <ailo> lamalex: The preamps probably aren't the best in the world, but that was not a concern of mine. There should be similar firepods too
[21:13] <ailo> lamalex: I did feel the focusrite had the specs and the price range I was looking for
[21:14] <len-dt> ailo, I think he is more interested in recording, pause then record.
[21:14] <ailo> len-dt: I understand, but he wants to maintain the connection he chooses
[21:14] <ailo> And for that he needs to set up a profile in patchbay
[21:14] <len-dt> ailo, yup
[21:14] <ailo> Each time you start any application that has connections set in the profile, they will connect the same way each time
[21:15] <lamalex> ailo, what's not so good about them? are they noisy?
[21:15] <lamalex> soundonsound seems to think they're nicer than the m-audio ones at least
[21:16] <ailo> lamalex: Nope. They are fine. I don't think you can find better preamps in that price range
[21:16] <ailo> The gain is a bit low on the mic pre's but no noise
[21:17] <ailo> _eein: What you do is you click "add" for each input and output you want to have presistent connections for
[21:17] <lamalex> soundonsound claims higher gain than the m-audio 2626, so maybe low gain is just a problem for this price range in general :P
[21:18] <ailo> lamalex: Could be. The gain was a bit lower than I was used to on mixer boards anyway
[21:18] <lamalex> ah yah i can imagine that being the case
[21:18] <ailo> Having to turn up a bit over half for vocals, which would be half normally
[21:18] <lamalex> sounds like you still had ample headroom though
[21:18] <lamalex> does jack work well with routing on this?
[21:19] <ailo> lamalex: jack is the only thing you can use with it. As for routing, jack is king
[21:19] <ailo> Since you can connect any app to any app, etc
[21:19] <lamalex> indeed, i guess i was trying to compare it's windows based routing software vs jack
[21:19] <ailo> lamalex: Oh. The internal routing is done with ffado-mixer
[21:20] <lamalex> ahh ok
[21:20] <lamalex> so does /that/ work well here
[21:20] <ailo> lamalex: 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 now
[21:21] <ailo> I actually muted all inputs and outputs during a live session when using ffado-mixer half a year ago. Needed to reset with a mac later
[21:21] <ailo> That problem should have gone away, if not with current Ubuntu Studio, then at least with the next upcoming release
[21:22] <ailo> Been 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 software
[21:22] <ailo> Otherwise, the internal mixer is quite usable
[21:24] <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 using
[21:24] <ailo> _eein: And all you need to do after that is keep that profile active, to have persistent connections
[21:27] <ailo> lamalex: 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)
