[linux-audio-user] gnome-terminal performance

by Florin Andrei

What do you guys think about this thread? http://mail.gnome.org/archives/gnome-list/2004-July/thread.html#00071 Am i crazy? Am i the only one who thinks that the current incarnation of gnome-terminal is slow and a resource hog? -- Florin Andrei http://florin.myip.org/

[linux-audio-user] jackit - qjackctl & xrun callback

by juto aviten

Hi friends, I just updated my mandrake 9.2 to 10.0 official and used the kernel.sds of thacs, everything is fine apart the fact that I used a terratec Aureon usb 5.1 and that I can't used it normally with jack, I put jackd interface: hw:0 frames/period: 2048 sample rate : 44100 buffer : 2 audio: duplex no memory lock input channels2 output channels6 I start jack and then xrun callback go over and over without end and there's no possibilities to start an apps (ardour, PD and so on...) And when I put 2input channels & 2 output channels it start without problems... but that's pity as the Aureon as 6 output channels to not used it :-( did someone report that problems, I changed the config of jack in qjackctl in different combinations but still the same scenario... thanks for your help!! juto

[linux-audio-user] Getting audio noise through midi cable

by Phil Carter

Hi, I have my keyboard midi ports connected to my computer through the game port on my motherboard sound card. It works fine, except I'm hearing some noise through the audio output on my keyboard when the midi cable is plugged into my computer. Whenever my computer is on (whether or not the keyboard is), I hear a buzz, and it gets louder whenever the hard disk is in use. Is there anything I can do to correct this? Is it because I have a cheap sound card? I've thought about getting a somewhat better soundcard, possibly an SB Live!, or a USB midi interface instead of my gameport midi interface. Any suggestions?

Maybe a full screen version of Reactor that could scroll vertically or horizontally... A visual means of patching back and forth... Maybe not as literal as Moog Modular but clear and easy to read. A nice simple gui like Vokator. Possibly with screens like Jahshaka/Blender so you could page rather than scroll and still keep the screen uncluttered. {I hate clutter}. Synthedit compatibility... The community there's fairly large... There's much stuff already written for the environment. If it were extensible through something simple like lisp or ruby... Like emacs and snd... That would be cool. Scripting is essential. VST is essential. ...LADSPA. OSC would be nice. Csound compatibility through a module would be cool... So you could read .orc and score files rather than just plugging in a step sequencer {Tho' a step sequencer would be nice.} PD compatibility would be nice. A sampler module would be nice. A timeline like the one in http://openvip.sourceforge.net/ would rock... either to actually do video or to set up samples. Automation would be nice Compatibility with existing languages/environments like cm and OSW {which is osc compatible already} would be cool... PVM? That way you could stretch it across a cluster. Mosix? Maybe peer2peer midi {Freshmeat}? Eyesweb compatibility {should they ever happen to port it}?

[linux-audio-user] headless audio apps

by robin fell

Hello [apologies for remotely on-topic post - i'm an X noob] Has anyone on the list any useful anecdotes about running X apps remotely (through ssh in my case) and having strange problems? Since I'm still in the process of setting up a terminal I haven't gotten a full list of the misbehaving apps - but I have seen ~30% load increase (as reported by an admittedly old qjackctl) upon starting meterbridge remotely (vs starting locally). I'm wondering if this is something I have this set-up incorrectly.... [I'd also be interested if anyone has any measurements for the performance benefits of remoting audio apps.] cheers Rob
