IndigentToad_Howdy05:45
IndigentToad_Does anyone have experience with the Lexicon USB interfaces?05:47
IndigentToad_Anyone alive tonight?06:05
len-dtIndigentToad_,  I don't know except what I can google.06:11
IndigentToad_len-dt - are you refering to Lexicon or your existance? LOL06:11
len-dtThe lex06:12
len-dtlexicon has been around much longer than computer audio...06:12
len-dtWhich one do you have?06:13
IndigentToad_Just the Alpha. Run the main outs of my mixer into it.06:14
IndigentToad_SHould have gotten the Lambda so I could use the sub outs06:14
len-dtSure doesn't say much on the manufacture's page06:16
IndigentToad_No. Fortunately Jack instantly recognized it.06:16
IndigentToad_But I'm curious if anyone has tweaked the settings and what results06:17
len-dtOk, that sounds good at least06:17
IndigentToad_I can get it to record in Ardour without any problems.06:17
IndigentToad_Fortunate06:17
len-dtI have heard some things that are general to USB IFs06:18
len-dtThat they run better with 3 Periods/buffer.06:19
len-dtI have found it is worth while finding a USB port that does not share an interrupt with anything else.06:20
len-dtIndigentToad_, are you recording? or would you do live work?06:21
IndigentToad_Right now just single track recording.;06:21
len-dtYou can use a longer latency then so long as you monitor from the Alpha's headphone jack or mixer if you have one.06:22
len-dtThat is basically what I am doing is one track at a time.06:23
IndigentToad_I'd like to keep it tight so playback is right on when I'm doing midi synth or on guitar06:23
IndigentToad_FluidSynth is pretty much on the money, but ZynSubAddFX has some lag06:25
len-dtI expect you will be trying to set Frames/period to 64 if it's stable and 128 if you have to go higher. I record at 64 and then add effects and mixdown at 102406:25
len-dtIf you can do it, you can record the synth as midi and set the synth later.06:26
IndigentToad_running 1024 Frames/Period now06:27
len-dtDepends though, some people play best when they can hear what it will sound like.06:27
len-dt1024 is pretty slow. you should be able to get it to run at 256, but you will be happier with 12806:27
IndigentToad_Lower the number, the faster?06:28
len-dtlower the number means less delay.06:28
IndigentToad_good to know.06:28
IndigentToad_256 is 1/4th the delay, but probably 4x the power06:29
len-dtI use guitarix at 128 and it sounds good.06:29
IndigentToad_Would that help with bad delay with Rackarrack?06:30
len-dtYup06:30
IndigentToad_I like the options with that, but the delay has always killed me. Almost a 1/4 sec delay06:30
len-dtany of the guitar effects for live use 256 is sort of the highest06:30
len-dt128 is better.06:31
IndigentToad_Is it always a power of 8? 8, 64, 128, 256, etc06:31
len-dtI haven't tried rackarack at anything higher than 64 actually06:31
len-dtpower of two.06:31
IndigentToad_My bad...06:32
len-dtA good PCI card can do 32.06:32
IndigentToad_using a laptop w/ the lexicon06:32
len-dtI get lots of drop outs at 3206:32
len-dtwith my netbook and a USB and everything set "just right" I can get 64 in a stable way.06:33
len-dt128 is a little better though.06:33
IndigentToad_Using a Core Duo with 1 gb RAM. I think 256 or 128 should be my goal unless I want to spend money06:34
len-dtI just using an Atom.06:34
IndigentToad_ok...hope for me then06:34
IndigentToad_LOL06:34
len-dtI found I have to remove the wireless driver while I am doing audio.06:35
IndigentToad_So far no problems here. I did disable the internal sound driver.06:35
len-dtIf wireless is connected I get an xrun per minute and if disconnected I get an xrun every 5 sec.06:35
IndigentToad_ick06:36
len-dtBut if I unload it, everything is fine.06:36
IndigentToad_No Xruns here unless I'm running a heavy soundfont w/ delay and reverb06:36
IndigentToad_My issue is that I only have three USB ports. One is for my wireless mouse, one is for the Lex, other swaps between my external HD and my midi controler.06:37
IndigentToad_Need a powered USB hub, but I worry it will cause issues06:37
len-dtI also found that the USB on the right side (USB3 on mine) has its own irq and works better than the one on the left.06:38
IndigentToad_true...if I can put things like my external HD and mouse on the hub, I think I will be fine06:38
IndigentToad_Running dual boot w/ Vista, so I only have 80 gb of hard drive per partition06:39
IndigentToad_Using GRUB - it's solid. No complaints so far06:39
len-dtI don't think I have ever run windows on my machines.06:39
IndigentToad_I got a wife and kids. They need it.06:39
len-dtMy wife did for a bit. she has ubuntu desktop now.06:40
IndigentToad_I'm a Ubuntu addict06:40
len-dtI started with slackware just before version 1.0 (version .9X06:40
IndigentToad_Wife can use FireFox in Ubuntu, but she needs MS Office for crap.06:41
IndigentToad_WINE is too much for her06:41
len-dtkernel wasn't even to 1.0 then.06:41
IndigentToad_I don't mind having Vista dual boot. Sometimes I like having office, too06:41
IndigentToad_rue06:41
IndigentToad_true06:41
len-dtMy wife is in school she uses libre office.06:41
IndigentToad_I did too for a while. Very functional06:42
len-dtWe found if we save as .doc and not .docx most windows computers can open it fine.06:42
IndigentToad_Minor differences,but fairly stable06:43
IndigentToad_Do you use Hydrogen at all?06:43
len-dtSome. Mostly as a click track :)06:43
len-dtI run hydrogen, play guitar and sing on to one track as a scratch.06:44
IndigentToad_I can do some decent tracks and record simultaneously with a midi track, too06:44
len-dtThen I lay down tracks while listening to that.06:44
IndigentToad_it's versatile. I've thought about a stand alone physical drum machine, but I don't know what it could do that hydrogen can't06:44
len-dtI have a small set of pads.06:45
IndigentToad_do you run them through hydrogen or something else?06:45
len-dtI haven't had a set for a long time06:45
len-dtTo be honest, I am still figuring that out.06:46
len-dtI would record to a midi track and then try things till I like it.06:46
IndigentToad_kewl...let me know because I've also been looking at midi pad controllers. Want to know how compatible they are w/ hydrogen06:46
IndigentToad_What are you using to record midi tracks? Ardour 3 or Rosegarden?06:47
len-dtMines 10 years old... and not even compatible with GM :P06:47
len-dtI have been using qtracktor so far.06:47
IndigentToad_sorry...got booted06:48
len-dtAnyway I have to go06:48
len-dtYa I saw that... happens.06:49
IndigentToad_LOL06:49
IndigentToad_Where you from LEN?06:49
len-dtComox vally on Vancouver Island Bc Canada06:49
IndigentToad_Central WI here. At least the same continent.06:49
* len-dt can even sometimes spell :P06:50
len-dtLater for you that me then.06:50
IndigentToad_True. Got Thurs off from the office. Spending some time in the basement...aka studio06:50
len-dtNot me, I have to work tomorrow. See you again.. Bye now06:51
IndigentToad_peace bro06:51
IndigentToad_Anyone else alive tonight?06:52
IndigentToad_*crickets chirping...06:57
=== james is now known as millerthegorilla
rickbolI see a new low-latency kernel is available in "updates", but I can;t select them for install (enable checkbox). How do I install this kernel?14:36
rickbol... 12.0414:40
zequencerickbol: Probably just give it some time14:45
zequenceGreat to finally have it though14:45
rickbol...that 'ol updater... always such a teaser.14:47
zequencerickbol: Are you using Ubuntu Studio with additional PPA(s) for audio?14:48
rickbolzequence: hmm, I haven't added any PPAs. I don't see any sources.list14:52
zequencerickbol: I wasn't considering the update issue. Was just wondering, cause my next question was: What do you think does not work well on Ubuntu Studio 12.04?14:53
zequencebbl14:55
rickbolI'm on my third wifi card (BCM4422). Finally stable. Been using AV Linux5.x. Transitioning to UStudio. My dvgrab->ffmpeg script doesn't work (but I've been stuck with generica-kerneL14:57
rickboleager to try new low-latency14:57
rickbolzequence: haven't had time to try real audio apps yet.14:58
rickbolI'm hoping ffado works better with my O2 Micro, Inc. Firewire (IEEE 1394) (rev 02)14:59
smartboyhwrickbol, hmm launch a terminal emulator, type sudo apt-get update, after the process type sudo apt-get upgrade && sudo apt-get dist-upgrade15:00
rickbolsmartboyhw: that'll take me to 12.10, no? Couldn't get wifi working on it either (Live CD). But I don't think I've tried this card.15:01
smartboyhwrickbol, no of course not15:01
smartboyhwto 12.10 you type sudo do-release-upgrade -d15:01
