Re: [linux-audio-user] Kernel 2.6.x latency

doing a 'dpkg-reconfigure xserver-common' should allow access to modifying this. Frank Barknecht wrote: > Hallo, > Sampo Savolainen hat gesagt: // Sampo Savolainen wrote: > > >>Yes.

[linux-audio-user] Kernel 2.6.x latency

by Sampo Savolainen

Hello, I'm trying to get jack & ardour working with the 2.6.x kernels. Do you have any hints/tips? I've now tried: debian 2.6.2 debian 2.6.3 debian 2.6.3 modified with LSM support + realtime module standard 2.6.4-rc2-mm1 (couldn't get realtime module working) standard 2.6.3-mm4 LSM support + realtime module (kinda working..) None of these have provided me with sufficient latency. Jack keeps throwing Ardour out for stupid reasons like closing the mixer window. (with realtime module, I mean http://www.joq.us/realtime/) Is there some magic trick I've forgotten to do, or I haven't heard of? I have DMA enabled on my harddrive, and this same system runs like dream with 2.4 kernels. Thanks Sampo

RE: [linux-audio-user] Good Sound Card for Pro Multitracking

by Polashek, Matthew

I would simply prefer to be able to hit 96K. I definitely need an external A/D/D/A unit for sound quality reasons. I can probably use external mic pre-amps. I have been considering using a Presonus DIGImaxLt with a RME Hammerfall 9652 but I think it ends up being cheaper to get an outboard box with balanced ins and outs and throwing some kind of 8 channel mic pre in front of it, unless there was a less expensive ALSA compatible option that had 8 mic pres and 8 outs.

RE: [linux-audio-user] Timidity and ALSA compile bug!

by Reuben Martin

Why are you trying to install version 2.9.5? That code in ancient. The ALSA API has changed significantly several times since that code was released. It's no wonder you can't get it to compile.

[linux-audio-user] ZynAddSubFX uses XML format - please test it

by davidrclark＠earthlink.net

Paul, I agree with Tim Hall's post: Thank you so much for writing such a great software synthesizer. Because you posted on LAU, I hope you don't mind my posting here. Perhaps (esp. with Jack), it may help someone out there... In reading writing XML, I found that it did not behave properly with respect to extensions: In asking to save new.xml, it saved newxml. Also, it could not find newxml because it looked for new.xml for Load. It also seems to load an unknown file when it cannot find anything. That is, instead of displaying "File not found" it seems to load something else. To get Jack to work, I went to src/Output and uncommented the jack_connect lines. I then substituted alsa_pcm:playback_1 and alsa_pcm:playback_2 for alsa_pcm:out_1 and alsa_pcm:out_2. Then it worked for Jack. I did not look at jack_RT. Thanks again, Paul. Very, very nice work. Best regards, Dave.

Re: [linux-audio-user] [Fwd: Edirol FA-101 Linux Support]

by Errandir

> From: Dan Harper <tech(a)danharper.org> > > I just sent this e-mail to Edirol. It may be useful to someone if > they're contacting them or any other company for Linux support. > > > Dan The FA-101 is based on the BridgeCo BEBOB, like a number of other products from Apogee, Tascam and Presonus that were presented at NAMM. If we could get support from one of these vendors it should be (relatively) easy to get them all working. People also talked about the M-Audio FW410 on this list before. I know it uses the DM1000 inside. Anyone know if FW410 is also based on BEBOB? Is anybody in touch with BridgeCo, or any info wrt their stand on Linux? But all this won't get us around the Yamaha connection management issue, will it? Martin http://www.bridgeco.net/products/bebob/bebob.shtml

[linux-audio-user] Re: [Alsamodular-user] Midi program change messages...

by Russell Hanaghan

Thank you, thank you, a million thank you's!!! I just tried this and can actually control elements for my needs. I'm only really using AMS as a "host" for various LADSPA plugins like Freeverb and delays for live vocal processing on a small PA. I have a multi fx guitar pedal with midi capabilities (limited) and need to be able to turn the FX of between songs as I talk to the audience. As simple as this was to do (when I knew where to look! And not to mention it did speak to it somewhat in the "manual" on Agnula), I was not finding how to get it done.
