[linux-audio-user] Cheap PCI MIDI interface

by Ross Vandegrift

Hey everyone, I remember back in highschool my band director bought a really simple 2x2 ISA MIDI interface for the band's computer. Does anything like that in PCI exist? I've looked around and didn't find anything that simple (ie, cheap ::-). What are people doing for this? The USB MIDI adaptors all seem really overpriced (they seem to start at around $40 for 1x1). I don't need the portability and would rather save the money. Maybe I should just find a pair of SB Lives used?

Re: [linux-audio-user] USB Audio + docking station/powered hub(audiotrak optopla

by Jonathan Beilin

the problem appears to be that most USB hubs (like my port replicator) only support asynchronous transfer while audio devices need isochronous transfers. That would mean, most likely, that if I plugged a hub that supports isochronous transfer, for example the griffin hub, into my asynchronous docking station I would still have problems... # lsusb -v | grep Synch just gives numerous Synch Type none listings so it looks like i have to ditch the docking station unless anyone else can think of something :( Thanks again, - Jonathan Beilin >From: Steve Harris <S.W.Harris(a)ecs.soton.ac.uk> >Reply-To: A list for linux audio users ><linux-audio-user(a)music.columbia.edu> >To: linux-audio-user(a)music.columbia.edu >Subject: Re: [linux-audio-user] USB Audio + docking station/powered >hub(audiotrak optoplay) >Date: Thu, 1 Apr 2004 23:04:48 +0100 > >On Thu, Apr 01, 2004 at 12:36:28PM -0800, Jonathan Beilin wrote: > > Hi, I'm running gentoo on a dell inspiron 8600 with a docking station & >a > > powered USB hub.

[linux-audio-user] USB Audio + docking station/powered hub (audiotrak optoplay)

by Jonathan Beilin

Hi, I'm running gentoo on a dell inspiron 8600 with a docking station & a powered USB hub. When I'm undocked with the audiotrak optoplay plugged in directly, it works fine. However, if I try to plug the optoplay in to the docking station or the wall-wart powered USB hub the optical-digital light is very faint and I get broken pipe reports when I send a signal to the device. What is wrong? Any help is appreciated; I'm tearing my hair out over this... all I need is un-resampled digital audio out. I thought I had it solved, but I do want to be able to use this with my docked laptop. _________________________________________________________________ Find a broadband plan that fits.

[linux-audio-user] beginner

by Josenildo Marques

Hello. I've been out of luck trying to work with sound on Linux. My experience with Audacity, Jack and Ardour haven't been successful at all. I was trying to create a .asoundrc file as, from what I read, it would be one of the first necessary steps. My soundcard is [cyb@kali cyb]$ cat /proc/asound/cards 0 [Live ]: EMU10K1 - Sound Blaster Live! Sound Blaster Live! (rev.8) at 0xa800, irq 10 and it's working well and I'm running Mandrake Linux 9.2 with Gnome. My attempt at editing a .asoundrc file is shown below pcm.!sb { type hw card 0 } ctl.!sb { type hw card 0 } pcm.jackplug { type plug slave { pcm "jack" } } pcm.jack { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2 } } which I copied and pasted from the Alsa site. Apparently it is working because when I issued some commands to play a file they worked. [cyb@kali cyb]$ aplay -d sd docs/voz.wav Playing WAVE 'docs/voz.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo[cyb@kali cyb]$ aplay -djackplug docs/voz.wav Playing WAVE 'docs/voz.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo However, Jack is not working properly and when I try to run Ardour all my running apps are killed and disappear. Jack shows the following messages: JACK compiled with System V SHM support loading driver .. open starting engine cannot set thread to real-time priority (FIFO/10) (1: Operation not permitted) cannot set thread to real-time priority (FIFO/20) (1: Operation not permitted) **** alsa_pcm: xrun of at least 10.319 msecs I'm very sorry if the message is bit lengthy, but I wanted to give all the info that I think is needed. Any tip or hint appreciated. TIA -- josenildo marques icq #289971493 homepage http://cyb.ezdir.net registered linux user #341648 ********* "Mistakes are the portals of discovery." James Joyce

[linux-audio-user] 3D audio technique

by toby＠tobiah.org

I have been working on a method of synthesis whereby a three dimensional space can be described through the careful arrangement of destructive interference nodes between sound sources. I have been able to translate three dimensional shape definitions into csound scores which feeds a csound orchestra instument that has been constructed to anticipate the location of interference patterns of low frequency sound sources, given the relative postions of the speakers. Not only is the audio product pleasing and artistically valid, but one can actually visualise the reconstructed shape in space between the speakers by exposing the space to a suspended cloud such as smoke or dust. By blowing smoke for instance between the speakers as csound 'plays' the score, a vague but recognizable reproduction of the original input shape can be seen. What happens is that the places where destructive interference nodes effectively stop the air movement, the cloud particles become more visible than in those spaces where the sound is active, and moving the cloud particles more rapidly. The effect can be quite astonishing, and opens, I believe, a very important new avenue of compositional expression. Here is an example of one of the more successful images, a bust of Beethoven: http://tobiah.org/beethoven.html Tobiah

[linux-audio-user] I may not get over this.....

by Geoff Beasley

Well, Kjetil Matheussen has done a fantastic job with vsti 0.0.3 and vstserver. Today I have run my N.I. Kontakt as a vsti for two hours on my RH9/CCRMA 1800XP 1 gig ddr PC with no x-runs on a soundblaster (!!) c/w the worlds best softsynth, Zynaddsubfx( this thing rules !!)... I am going to kick the XP sampler out of the studio tomorrow. You've got to try this !! I have been waiting for this moment for such a long time. Frankly I don't care if it crashes every hour on the hour, at least I'll be running Linux and the only way from here is UP !!! Now if Paul would just release beta 12 of Ardour, that could be another XP biting the dust... who knows !! Thanks sooo much to all involved for a great OS and some amazing programming ! Jack/Ardour/Alsa/CCRMA/Zynaddsubfx/Qjackctl/ and so much more coming... very exciting. Geoff
