[linux-audio-user] help needed with RME MADI card

by Ben

I recently picked up an RME HDSP MADI card to test it as a playback source for a digital mixing console. For testing purposes, I loaded it onto a VIA epia board (yes, you read that right, 600 MHz, baby!) and installed the recently released DeMuDi 1.2. When DeMuDi loads, the first thing I do is modprobe snd-hdpsm. Then I can start jackvia qjackqtl and it shows 64 record channels and 64 playback channels. Success!! kinda.... Now I'm stuck. I can't figure out how to change the mixer settings. I've studied all the info at the ALSA site and on Winfried Ritsch's site but I'm too much of a noob to know what it means. hdspmixer apparently does not support this card yet. It says: Card 0 : RME HDSP MADI at 0xde000000, irq 10 No Hammerfall DSP card found alsamixer seems to have no effect (?) I think the playback channels are not routed to the outputs. Winfried has some example apps that use the hwdep-interface to set mixer values but the .tgz file seems to be corrupt. using tar -xvf or -xvf it reports the file is not in gzip format. Questions: How do I set up the card so that Jack can read/write all 64 inputs and outputs, with no attenuation in the card's mixer? Does anybody have a valid hwdep-interface example for this card? (I am trying to contact Winfried but I'm not sure I have a valid email address for him) Thanks for any help, Ben Loftis

Actually, Reason's probably closer. If it would work with virtual desktops and there were some planning put into placement of gui stuff {omnipresent, floating toolbars,etc.} that might be nice. http://www.propellerheads.se/ Moog modular uses realistic patch cables to interconnect modules.

Code optimized for Parallel virtual machines and Mosix clusters... lots of processing power cheap. Peer2peer midi synchs it netwide.

[linux-audio-user] Jamin question - peak hold in spectrum display?

by Mark Knecht

Hi, Does Jamin have any facility to do a peak hold display where a second curve is drawn and is made up of the peak values displayed in the faster, currently existing curve? If so, how do I turn it on? This is useful when you're trying to get an overall feeling for the energy across time instead of what's happening at a specific instant. Also, I don't see (but am probably missing) a way to set the decay speed of the display. Typical sort of fast (what's there now) medium and slow. Often the peak hold operates pretty close to the slow curve, or sticks around permanently until you do a reset by hand. FYI - right now the Gentoo version is 0.8.0 and there is an error message at startup about not finding lookahead_limiter_const_1906.so. I don't know about the sound yet but I must say that the basic tool compares pretty nicely to the Waves stuff I normally use. I'm currently mixing a CD and looking at using Jamin for my final version. Thanks for a nice tool. Thanks, Mark

[linux-audio-user] slightly OT: sound is choppy in skype

by Atte André Jensen

Hi It seems (http://forum.skype.com/bb/viewtopic.php?t=4068&sid=7c8eb62c7f9a5c611b24b9dc…) that it's a known thing that skype is not working for some linux people, including me. I'm on a well configured debian/unstable system running kernel 2.6.4 on a PIV2.4 laptop (sound card is i810). Anyone here experienced problems like this with skype *and* can point me in the direction of a solution?? -- peace, love & harmony Atte http://www.atte.dk

Re: [linux-audio-user] Effects Box --- HARDWARE Type

by davidrclark＠earthlink.net

Frank - Mark, Thanks to both of you for replies. (Good to hear from you, too Mark!) Using kaconnect shows only MIDI ports, same as ALSA patch bay. What Frank said is correct. I had some improper mixer settings (duh!), so couldn't get PCM in's to be hardware in's. I needed some reassurance that Jack really could do this; the outputs were working fine, so it was temporarily confusing me, as in "What????" Like many of you, I have too many cables and switches around here! --------------------------- For those who have external devices (synths, mixer): I should perhaps point out to those who may not have thought about this that they can use their onboard (probably crappy) sound capability as an effects box rather than have it sitting idle, especially for effects that are low-level and doubly especially for distortion, etc. Just route your Aux send into the card (I'm using a Y to get it into both channels in Line in), run the output back to the Aux returns. Fire up jackd with -d was_idle_soundcard and jack-rack. Use jack-patch-bay or whatever to connect the soundcard inputs to jack-rack and jack-rack outputs to soundcard outputs. Be sure to mute line, but use it as a capture port and be sure to enable PCM. I think that's it. Now you have an effects box. I hope I described that all correctly, but people should get the gist of it. It does all actually work. Apologies to those who already know all this. It had never occurred to me before to utilize my idle soundcards in this way. --------------------------- Thanks again and best regards, Dave.

Re: [linux-audio-user] OT: Microphone info

by Aaron Trumm

Hey there - you need to do some research on specific mics and types of mics for your particular application - it may well be that there are 3000 dollar mics that won't do the job you need as well as a 120 dollar mic - for example, I don't think I'd stick 4 neumann u87s on the snare and toms of a drum kit rather than 4 shure sm57s oh gosh - I had some links but i'm not at home - rats...hmmm - uhm...hmmm - i think maybe i put some links about mics in my linux journal article: www.linuxjournal.com/article.php?sid=7205 ------- NQuit www.nquit.com ------- ----- Original Message ----- From: Alastair Couper Sent: 8/3/2004 1:50:24 PM To: linux-audio-user(a)music.columbia.edu Subject: [linux-audio-user] OT: Microphone info > I am looking into getting a decent microphone, but am having a hard time > wading through all the obviously subjective yet passionately held opinions > that I see in various reviews.

[linux-audio-user] Fwd: AqsisMovieProject

by Brett W. McCoy

I'm forwarding this on because we need folks to help out with sound design in addition to CG stuff. Aqsis, in you've never heard of it, is an open source REYES rendering suite that is Renderman-compliant. -------- Original Message -------- Subject: AqsisMovieProject Date: Tue, 03 Aug 2004 12:28:51 -0400 From: Brett W. McCoy <bmccoy(a)chapelperilous.net> To: aqsis-development(a)lists.sourceforge.net A few of us have been conspiring on the Aqsis IRC channel (#aqsis on freenode), and have started the pre-planning stages of a short CG film produced entirely with open source/free-as-in-speech software. And by "entirely", we mean everything -- modelling, audio, editing, pre-production, etc. At the center of this, of course, will be Aqsis. Right now we are recruiting a full production team to help get this project off the ground. This means: * producer/project managers * script writers * modellers * animators * shader writers * editors/post-production * directors * sound design * music The first and most crucial thing we need is a high-level producer/project manager. We have a couple of the other positions filled, but we need someone who has the time and commitment to manage the entire project. Please visit http://aqsis.sourceforge.net/cgi-bin/aqsiswiki.cgi/AqsisMovieProject for more details. If you want to volunteer, please sign up via the Wiki! -- Brett http://www.chapelperilous.net/ ------------------------------------------------------------------------ The UNIX philosophy basically involves giving you enough rope to hang yourself.

[linux-audio-user] Effects Box --- HARDWARE Type

by davidrclark＠earthlink.net

Greetings all, Jack-Rack with plugins can be used as an effects box for PCM inputs. What about HW inputs? I don't see a way to hook HW1/HW2 on my sound cards to effects programs. The program would be something like a full-duplex record program that would allow capture on HW1/HW2, process in effects rack, then output to PCM1/PCM2 on the same card. Although I'm not very familiar with Cubase, it noticed it allows effects processing of HW inputs before output. Not many programs do this; most process only PCM inputs from what I can tell. Thanks very much for any information. I have external synths and mixer. It would be nice to utilize my spare audio cards as effects processors for the external mixer via Aux send/receive's (both, not just "send"). Dave.

[linux-audio-user] Re: RME MADI card

by Ben

Regarding my HDSP MADI woes, the .tgz file on Winfried's page was tarred, but not gzipped. Hence my confusion. So maybe now I can get the mixer utilities working. -Ben Loftis
