[linux-audio-user] Getting jackd to use tmpfs?

by Chris Metzler

Hi, The JACK FAQ suggests creating the mount point /tmp/jack, and placing a tmpfs filesystem there, for jackd to use. Doing so doesn't seem to have any effect -- my jackd continues to do everything in /tmp. Is it also necessary to recompile jackd to get it to use that new tmpfs filesystem? In the same part of the JACK FAQ, there's a bit about creating a similar mount point at /mnt/ramfs for JACK to use for FIFOs; it doing so requires the setting of a compile-time option. Is this just a muddy description of what to do that should be condensed a bit, and my problem is that I do need to recompile jackd? Or am I missing something else here? Thanks, -c -- Chris Metzler cmetzler(a)speakeasy.snip-me.net (remove "snip-me." to email) "As a child I understood how to give; I have forgotten this grace since I have become civilized." - Chief Luther Standing Bear

[linux-audio-user] Planet/Fedora/Nvidia Problem

by Greg Reddin

This question is really more related to installing drivers to a "non-booted" kernel. My computer has an ASUS MB. The video (non-integrated) and network require the nforce drivers from NVidia. I had manually installed some audio tools including a lowlat kernel under RedHat 9. But I decided to install Fedora Core 1 and use Planet CCRMA. So I installed the CCRMA kernel and source. I didn't expect the network or graphics to work when I booted the new kernel b/c I'd need to install the NVidia drivers again under the new kernel. But when Fedora got to the "graphic" portion of the bootup, the screen went blank. I thought I'd just switch to VC1 and install from a text logon, but I was never able to switch to VC1. Now, in hindsight, I think I didn't quite wait long enough for the system to boot up so I'll try again tonight. I was in a hurry and had to get to work this morning. But, if I had to boot the standard kernel, is there a way I could install the NVidia drivers from there? How do I tell them to compile against the lowlat CCRMA kernel? How do I tell them to install to the appropriate place? It doesn't seem like this would be terribly difficult. I just don't know what parameters/environment variables to change. Thanks, Greg __________________________________ Do you Yahoo!? Get better spam protection with Yahoo! Mail. http://antispam.yahoo.com/tools

[linux-audio-user] midi issue and Event EZBus letter

by Kent, Gary

Frank: When you say supported as a USB-device does that mean that essentially my Linux box will recognize it as a device which allows me to use it as a recording device into Ardour or Muse or Audacity (in this case allowing 2 channels of recording) just as I would in my Mac, but just bypassing all of the Event provided interface software such as the Mix Librarian and templates that are issued for Win/Mac users? I understand your concern for wanting the source itself instead of a version done by the manufacturer. I guess I was just eager about an Event driver since when I see the RME products that work well with Linux I assumed that this is how RME was issuing their drivers, namely, from within their organization. Does RME or M-Audio give their code to Linux developers? Thanks for the reply, gk

[linux-audio-user] Question, not quite linux related

by Tracey Anne Hytry

Hi everyone. I know there are quite a few people here who do music, and this is a question about a piece of equipment. I'm asking here because I feel much more comfortable asking here. My question is: If you could afford a Roland MC-909 would you buy one? Christy and I were at the local guitar center and there was a 909 there that someone was "playing" in real time. It was quite the instrument for doing techno type jamming. Christy played with it a little and really got into it, and got "that gleam in her eyes". After we came home I looked it up on the net, and found a few good reviews. The 909 is at a good discount also. I guess my only problem is how well will this thing work with linux as far as it's fastest way to load samples(via usb). I kind of doubt that it will, which would make loading samples a little harder, but not impossible. It seems like a great sequencer, that would fit in real well with the rest of the equipment we have around. It would also free up the linux music machine to better do recording, special effects, and synthisis. Anyway, has anyone had any experience with the Roland MC-909, and what is your opinion? Please feel free to email me if you would like (but please put [linux-audio-user] in the subject line so it doesn't fall into the spam box). Thanks in advance, Tracey.

[linux-audio-user] MIDI + Audio

by cv223＠comcast.net

Hi, I'm trying to set up my Linux system for a number of audio projects. My first idea was to tap into the wealth of audio tools available to help me practice. The basic idea is to generate a MIDI file of a tune using one of a number of programs (mma, gmorgan, pymprovisator, etc.), play the midi file through a sequencer like MusE or Rosegarden while recording my audio part (I play bass) for later post-mortem analysis. This seemingly simple task has me stymied. I have jackd (via qjackctl) and fluidsynth (via qsynth) running ok, but I have two completely different problems with MusE and Rosegarden: 1) MusE 0.6.2: Audio input seems to work (audio mixer in MusE shows signal), but there is no sound when MIDI plays back. I've turned up every fader I can find and still no MIDI output. The little "jumping bars" on each MIDI track indicate that _something_ should be happening. I don't get sound from the built-in softsynths, either. I must be missing something simple! A mute button? A master gain control?? The fluidsynth MIDI part of the signal chain seems fine, because of 2), below. I was previously working with MusE 0.6.0, which gave MIDI output after a bit of fussing - maybe I should go back to it? 2) Rosegarden4 0.9.6: MIDI output works fine, but I get no audio input (the audio input indicator doesn't show anything, and recording shows silence). The audio part of the signal chain seems to be working because of 1), above, plus I can record audio with Ardour ok. I was previously trying version 0.9 where the audio recording worked, but there was a huge delay between the MIDI and audio tracks. Info I saw on the Rosegarden users email list seemed to indicate that 0.9.6 should fix a problem with MIDI recording delay, so I figured it would do something about the audio delay. In both situations, jackd connections are what I would expect (e.g., with Rosegarden, qjackctl shows an audio input connection to Rosegarden). If anyone has any ideas, I would _greatly_ appreciate suggestions. BTW, I'm running a Gentoo system with the latest ebuilds for these programs, if that helps. Thanks, Joel PS Double thanks to everyone who has contributed to all the cool Linux audio apps!

RE: [linux-audio-user] Guitar overdrive

It's a jack client rather than a LADSPA plugin, but you may also want to try out creox. http://www.uid0.sk/zyzstar/?creox >Can anyone recommend any LADSPA plugins that will get me a nice guitar >overdrive sound?

Can anyone recommend any LADSPA plugins that will get me a nice guitar overdrive sound? (my friend took back his Marshall I was borrowing, now I need a software replacement) Thanks, Dan

[linux-audio-user] USB under 2.6.2

by David Baron

There have been a lot recent postings about various USB devices. Assuming that I have indeed blacklisted the OSS driver and snd-usb-audio is registering, etc. It still will not work unless the new module uhic-hcd (instaead of usb-uhci) is loaded. However, this module will not unload correctly and can cause a hangup on shutdown. Get stuff like: URB-status -104 USB-request-URB -32 and hangs. Doing a rmmod (or modprobe -r) does not succede and anything dealing with modules is now parallized. lsmod, etc., are no longer accessible. NO usb until this business is cleared up, I am afraid. (If anyone has solved it, please let the rest of us know how!)
