[16:13] <brycebudd> hey all, can someone point me to a url that will list what services I can safely disable for recording with ardour?
[16:14] <holstein> services?
[16:14] <holstein> like ssh and the like?
[16:14] <holstein> you need JACK running
[16:14] <brycebudd> correct system services
[16:14] <brycebudd> understood
[16:14] <holstein> i dont see any reason why you should disable any services though
[16:14] <holstein> i mean, disabling what you arent using is safe of cours
[16:14] <holstein> e
[16:16] <brycebudd> Let me phrase it a different way...what are the essential system services to safely run an ubuntu system and gain maximum system performance and memory?
[16:17] <holstein> that all depends
[16:17] <holstein> are you using USB?
[16:17] <holstein> firewire?
[16:17] <holstein> do you need networking?
[16:17] <holstein> is this an audio production rig only?
[16:17] <holstein> i  would start with this... what do you *not* need
[16:17] <holstein> like maybe bluetooth
[16:17] <ailo> brycebudd: My experience is that you don't gain a lot as long as you have a good kernel. Even not installing the entire desktop makes little difference
[16:17] <holstein> i say, at the end of a few hours of tweaking, you will really reclaim nothing useful
[16:18] <brycebudd> yes, audio only...
[16:18] <holstein> theres no reason to disable a bunch of services for doing audio
[16:18] <holstein> *maybe* doing video, you *might* notice
[16:18] <holstein> audio really isnt all that hard on the sytem
[16:18] <holstein> system*
[16:19] <brycebudd> ailo: thanks for sharing your experiences...that's exactly the kind of feedback I'm looking for!
[16:19] <ailo> It's not so much about cpu and RAM, more about priorites
[16:19] <ailo> And the kernel handles that +  jack + settings
[16:20] <brycebudd> so in your opinion what are the best ways to measure and reduce latency, reduce xruns etc.  Is it just playing with settings or are there "magic settings" that generally work.
[16:20] <holstein> that depends on the hardware
[16:21] <brycebudd> I usually use Jack, Hydrogen, Seq24, Patchage, and Ardour
[16:21] <holstein> if you are using an internal soundcard, i wouldnt expect under 20ms latency
[16:21] <brycebudd> unfortunately...only USB.  No native cards
[16:21] <holstein> USB is sometimes better
[16:21] <ailo> brycebudd: Just make sure you have realtime priority for the user. Other than that, it might mostly depend on the type of kernel, as well as the kernel version
[16:21] <holstein> and at least its external, and typically cleaner
[16:21] <brycebudd> I've been getting 11ms reported in JACK using M-Audio
[16:22] <holstein> 11 is pretty good
[16:22] <holstein> tolerable
[16:22] <holstein> depends on what you are doing
[16:22] <brycebudd> recording drum tracks with a Roland TD-20
[16:22] <holstein> if you do no live instruments, or effects processing.. who cares if it takes 70ms for the sound to come out the speakers
[16:22] <ailo> brycebudd: Is that an external synth?
[16:23] <ailo> alsa midi is really lousy when it comes to external midi gear
[16:23] <brycebudd> no electronic drum kit.  I can sync to Seq 24 via MIDI.
[16:23] <brycebudd> ailo: what is better?
[16:24] <ailo> jack midi is better
[16:24] <ailo> Not all apps support it yet
[16:24] <brycebudd> ah...I will play around with that tonight. Thanks for the tip!!
[16:24] <ailo> brycebudd: Choose "seq" as the midi driver in qjackctl
[16:25] <brycebudd> good!  that's what I'm using (I just didn't know it) *blush*
[16:25] <ailo> brycebudd: If you're using the lates jack, alsa midi will still be active
[16:26] <brycebudd> ailo: should I disable?  if so how?
[16:26] <ailo> Jack midi supported apps will appear in the "MIDI" tab, and not the "ALSA"
[16:26] <ailo> Just make sure the app you use is set to jack midi, and not alsa midi
[16:27] <brycebudd> ailo: I get it...understood. thanks!
[16:29] <brycebudd> byebye
[16:31] <neyder_> hi!, in precise, how can i install the audio metapackage ober an edubuntu installation'
[16:32] <holstein> neyder_: i would just open the package manager of your choice, and search "ubuntustudio"
[16:32] <holstein> i would also consider just installing what you are wanting to use.. JACK, ardour... hydrogen... for example
[16:33] <holstein> sudo apt-get install ubuntustudio-audio should get you the metapackage you are looking for though if you prefer
[16:38] <neyder_> gret, i was asking because "apt-cache show ubuntustudio-audio" tells me that is a transitional package to Audio Seed
[16:38] <neyder_> *great!
