[linux-audio-user] Re: More Homemade Music

by Gavin Stevens

Hi Steve, Very nice track. I really like the bittersweet harmonies & personally I like the saw lead sound - I understand your choice. Thanks for sharing.

[linux-audio-user] Using Linux as Bass amp

by Christoph Eckert

Hi, I just ordereed an electric bass (passive). I'd like to directly plug it in into my soundcard and to use Linux as an amplifier (and record it to ardour, of course). As I'm not yet familiar to basses and guitars yet, I wonder what I should use for the bass. There's creox, but it's a bit dated. OTOH, I thought jack-rack could be my friend. If so, which LADSPAS can I use in conjunction with a bass? I guess (but I do not know) that a compressor can do a great job. There are several LADSPAS for it, so if anyone has a working setup I'd be glad for some hints. Thanks & best regards ce

Defaults to traditional behavior. Originally written by Chris Wright. The patch implements a simple rlimit ceiling for the RT (and nice) priorities a task can set. The rlimit defaults to 0, meaning no change in behavior by default. A value of 50 means RT priority levels 1-50 are allowed. A value of 100 means all 99 privilege levels from 1 to 99 are allowed.

Re: [linux-audio-user] OT: Using Linux as Bass amp / preamp

Keep us posted on how it works out. I'd be curious to hear what you think of it. I've put my bass through the stripped down DI-100 which gives a phat, clean signal to work with. I usually end up using a compression (although it looks like the mic200 has a built-in limiter) and/or EQ plugin to get the bass track to sit comfortably in the mix. If the mic200 sounds good and has some versatility, it would seem like it could get some heavy use on vocals and other instruments as well. cheers, Neal ____________________________________________________ Yahoo!

So you can do it yourself, of course.

[linux-audio-user] snd 7.14 and gtk

by Bill Schottstaedt

> I would use snd-7.14 > but none of the xm xg stuff seems to work for me. It just makes snd > segfault if I compile it with xm or xg support As I mentioned on cmdist, the gtk side of snd 7.14 is a mess right at the moment, due to a serious lack of coffee or something (I merged a half-done update by accident). It's a day-to-day thing -- today's version might even work. If it doesn't, please run snd in gdb and send me a stack trace -- it might be something I don't know about.

[linux-audio-user] simple usb audio question?

by Dylan McNerney

This is probably a very basic question, because all references to usb audio seem to relate to quality, rather that getting the device working, but I'm new to linux. Currently I can't capture from or play to my Edirol UA-25. I assume it is in conflict with the onboard soundcard which is an nForce3, but don't know which modules to remove, etc. I tried taking out the snd_intel8x0 driver, but then mixers didn't find anything at all. The device seems to be recognized in the sense that the Suse control center sees it as a midi controller, and I tried to add it as a generic usb audio in YAST, which seems to have put it at hw [1]. I followed the ALSA project instructions for the modules.conf file and .asoundrc but not sure what I should be looking for now. I'm running Suse 9.2 x86_64 with custom 2.6.11.12 kernel with realtime_lsm module. The device works fine in windows. Thanks for any help.

[linux-audio-user] Low latency USB 1.1 card?

by Christoph Eckert

Hi, my terratec card provides very high latencies (more than 40msecs), so I wonder if there are cards out there which are USB 2.0 compliant but can be used on my USB 1.1 machine (until I get a new one) at low latencies. Anyone can tell about such a card? I do not need MIDI ports, but full duplex 2 in 2 out with a mic in and a headphone out would be great. More ins and outs are welcome. Because I'm a hobbyist, the cheaper the better ;-) . Thanks & best regards ce
