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