[linux-audio-user] Re: [Audacity-users] Multi-input sound cards

by Daniel James

> I'm very patient and would eagerly help you test the multi-channel > recording abilities. I'm not always patient but I could help there too. If Dominic has a USB Quattro already, maybe we should do a quick survey of what other devices are available/needed for testing. I was thinking of getting a PCI MAudio card for this. I'm cross-posting to the Linux Audio User list, because I'm sure there are some people on there who would like to give Audacity with multi-channel input a go. Cheers Daniel

[linux-audio-user] Yamaha style editor ?

by Ryurick M. Hristev

Hello, Is there an editor available which could understand the Yamaha style files ? They seem to be some sort of MIDI files with some bits flipped here and there to mark the sections. Timidity can play them sequentially but Rosegarden barfs. What else should I try ? (I couldn't find anything specific) TIA Cheers, -- Ryurick M.

[linux-audio-user] Audio restoration

by Sergi Roig

Alexander, thanks for the link, I will certainly give it a try. It hurts to say so, but I miss the audio restoration features built in Cool Edit Pro for M$ Windows since I migrated 100% to linux; those tools were, IMO, as powerful as easy to use. If you know of any tool out there which is similar to that, let me know (gwc doesn't seem to work very well...). Thanks! Sergi <Greetings, < <I'm sorry for this cross-posting. < <I've just figured out that there is a sound restoration plugin on <LAOE (http://www.oli4.ch/laoe/).

[linux-audio-user] Mailing list for general music making questions?

by Darren Landrum

Hey, all. I thought of something today that I think would be of good use to many folks. I was wondering, is there a mailing list somewhere for people to talk to and educate each other on such things as music production, software use, micing technique, best drum kits, or anything in between? If not, how useful do you think this would be to those of you on this mailing list? I was also thinking it would be a good place to announce new recordings of songs. If enough people would like this, I have my domain on a new server with mailing list software that's actually worth something, and I would be willing to start and host it. Since this is just a mailing list, and those are generally fairly low-maintenance, this would not foreshadow any of my work on the Open Music Resource Library (such as it is right now). Thoughts and opinions? Regards, Darren Landrum

[linux-audio-user] Getting alsaplayer to work with Audiophile

by Frank Barknecht

Hallo, I have a M-Audio Audiophile card (snd-ice1712) in my box, and for month I cannot get alsaplayer to work with it in ALSA-mode. I currently use $ alsaplayer --version alsaplayer 0.99.70 from the unstable Debian package. But it didn't work with any prior version. Actually I like alsaplayer, because it runs very stable without dropouts, but in my case it doesn't deserve its name. This is the error I keep getting when starting alsaplayer ("-d default", "-d hw:0" all give the same): $ alsaplayer error on set_periods (13) Unavailable hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: 44100 PERIOD_TIME: (11609 11610) PERIOD_SIZE: 512 PERIOD_BYTES: 2048 PERIODS: [1 13) BUFFER_TIME: (11609 148595) BUFFER_SIZE: [512 6553] BUFFER_BYTES: [2048 26212] TICK_TIME: 10000 error on set_periods (7) Unavailable hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: 44100 PERIOD_TIME: (23219 23220) PERIOD_SIZE: 1024 PERIOD_BYTES: 4096 PERIODS: [1 7) BUFFER_TIME: (23219 148595) BUFFER_SIZE: [1024 6553] BUFFER_BYTES: [4096 26212] TICK_TIME: 10000 failed to configure output device...trying OSS Yeah, "trying OSS", you wimp! ;) Has anyone with an Audiophile alsaplayer working? ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] soundfonts, iiwusynth and smurf

by Levi Burton

Hello, I am currently using alsa 0.9rc7 with oss emulation, oss sequencer, virmidi and ens1371. I have a ens1371 soundcard. I would like to create my own soundfonts using smurf and play them with iiwusynth. Does anyone have some insight into the best way to proceed with this process (workflow, devices etc etc). I am a little overwhelmed by the amount of options there are for doing this. Thanks! -Levi

Well, OK, I guess I don't understand the meaning of 'ports' then. The HDSP only has two sets of in and out connectors. Are these not ports? Or does the Alsa spec think that each 'port' is somehow combination of a MIDI connector and a channel or something? How is it that a single input uses up 32 port number? (HDSP 9652 MIDI 1 seems to go from port 0 to port 31, and I guess #2 goes from 32-63.) > > >2) Why does the HDSP 9652 not tell me its name like the MidiSport does? > > its using a copy of some generic ALSA code that just calls the ports > "MIDI C P" where C=card number and P=physical port number. i'll change > this when i add the fixes for the mixer and the h/w names. > This would be very helpful.

[linux-audio-user] Planet CCRMA Cmucl can't find core

by Larry Troxler

Before diving into my particular question, I want to say that planet CCRMA is great! the documentation is superb - - Just wondering if there is a quick, easy answer for this - the problem is that after installing cmucl from planet CCRMA using apt-get, it doesn't run: ~ ~ ~ root@dhcp-25-2 root]# lisp Could not open file "/usr/lib/cmucl/lisp.core". Maybe you should run "update-alternatives --config cmucl-core" as root? open: No such file or directory [root@dhcp-25-2 root]# ~ ~ ~ [root@dhcp-25-2 root]# rpm -qa | grep cmucl cmucl-3.1.4-1 [root@dhcp-25-2 root]# rpm -qi cmucl Name : cmucl Relocations: (not relocateable) Version : 3.1.4 Vendor: (none) Release : 1 Build Date: Fri 20 Dec 2002 04:01:30 PM EST Install date: Sat 15 Feb 2003 09:06:10 PM EST Build Host: nando.stanford.edu Group : Development/Languages Source RPM: cmucl-3.1.4-1.src.rpm Size : 944001 License: see /usr/share/doc/cmucl/copyright Signature : (none) Packager : Fernando Lopez-Lezcano <nando(a)ccrma.stanford.edu> URL : ftp://http.us.debian.org/debian/pool/main/c/cmucl Summary : The CMUCL lisp compiler and development system.

[linux-audio-user] is ext3 ok for real-time / low-latency?

by Larry Troxler

Well, since my installation (mostly RedHat 7.1) was getting to be a big mess, with bits and pieces from different places, I decided the best way to get a working C++ compiler was to get a new drive and do a fresh redhat 8.0 installation :-) My immediate question: is ext3 bad news for real-time work? I saw some linux-audio-dev list messages from people who were having freezes using it. Should I convert my filesystem back to ext2 (assuming there is a way) or not? Which one in theory (assuming no bugs which seems to be the cause for the freeze) should be better for low-latency work? Thanks in advance! Larry Troxler

[linux-audio-user] Please explain Alsa Interface MIDI numbering PLEASE!

by Mark Knecht

Hi, I'm having a great deal of confusion about how Alsa is handling my MIDI hardware. This is spilling over into unintended consequences in Rosegarden that I think none of us understand. Couple someone with some background in this please explain? Thanks. I have two 2-port MIDI devices on this system. One is an RME HDSP 9652 with two MIDI ports, and the other is a hot pluggable MidiSport 2x2. I attach two screen shots of kaconnect, one with and one without the 2x2 plugged in. My questions: 1) In the screen shot "without_2x2.png" I see two read ports and two write ports. Please explain why they are called 64:0 External MIDI 0 64:32 External MIDI 0 Why is my HDSP given the apparent name '64'? Why the :0 and :32? I would have thought :0 and :16 would make more sense from a channel numbering point of view, or :0 and :1 from an interface point of view. What's going on? 2) In the screen shot "with_2x2.png" I've plugged in the MidiSport 2x2. New devices show up in kaconnect. However, instead of showing 2 read ports and 2 write ports, I am getting 4 read ports and no write ports. Please explain why the MidiSport is given the names 72:0 External MIDI 1 72:1 External MIDI 1 72:2 External MIDI 1 72:3 External MIDI 1 Shouldn't this be just :0 and :1 for both the read and write ports? I get the feeling that BOTH of the drivers for these devices are hosed. What's up with these things? I do not understand why Alsa gives these devices numbers in the first place, nor how the numbers are assigned. How can I change the names that are displayed so that "64:0 External MIDI 0" shows the name "HDSP 9652 Port 1" "64:32 External MIDI 0" shows the name "HDSP 9652 Port 2" "72:0 External MIDI 1" shows the name "MidiSport 2x2 Port A" "72:1 External MIDI 1" shows the name "MidiSport 2x2 Port B" Thanks very, very much in advance, Mark
