[linux-audio-user] NoteEdit questions (multiple staves)

by Mikhail Ramendik

Hello, As far as I know, no NoteEdit mailing list exists. So I have to ask here... I have installed NoteEdit and am trying to use it (or actually, to help mu musician wife use it). But we don't understand a couple of things. First, to create two staves that are for the same instrument? This is common in piano scores - one staff with the trebke clef for the right hand, plus one staff with the bass clef for the left hand. Bars, repeats, etc. should go across both staves. Such staves are usually joined by a brace (accolade?), but as NoteEdit is not a direct printing editor, the absence of the brace itself may be quite understandable. Second, is it possible (and if yes, how) to enable some sort of line wrapping, as common in printed scores? Working with one long line is somewhat inconvenient. -- Best regards, Mikhail mailto:mr@ramendik.ru

[linux-audio-user] MusE/Jack Installation

by BartonBosch＠aol.com

I am trying to install MusE, which means installing Jack as well. The first issue that I have run into is that MusE requires glibc 2.3.1 or better to compile. My RH 8.0 has glibc 2.2.93-5. Will updating to 2.3.1 cause my previously installed binaries (i.e., the entire system) to stop working? Or is 2.3.1 backwardlycompatible with 2.2.93-5? Or can you have both libraries on one system simultaneously? In other words, what are the ramifications of updating glibc? Then there are the same considerations for updating qt 3.0.5-17 to 3.1.0 or better, except that it is my impression that qt is much less central than glibc. Would anything (everything?) need to be recompiled with this new version of qt? Another issue relevant to both of the above is the question of RPM vs source installation. There are i386 +/or i686 RPMs for both qt and glibc on the Red Hat site. Any suggestions as to whether I should install from source or from those RPMs? Which of the RPMs would be better to install on a Celeron 300A? Finally, in preparing to install MusE I installed fluidsynth and libsndfile. Fluidsynth seemed to go without a hitch (tho I haven't used it yet) but libsndfile's configuration summary suggested that I add /usr/local/lib/pkgconfig to the PKG_CONFIG_PATH variable because other programs compiled against libsndfile might need it. Sure enough, when <./configure>ing jack, it couldn't find sndfile.pc, and while <make>ing jack, it exited with an error. I tried: env $PKG_CONFIG_PATH=/usr/local/lib/pkgconfig and it listed all the env variables with the appropriate entry appended. Thinking that everything was set, I tried to re<./configure> and <make> jack, but it exited with the same error. Double checking with <env> showed that the new entry had disappeared. I double checked this, and every time I set the variable with env, it lists it once, then it disappears on further <env>s. Anyone know what is going on here? Thanks, Barton P.S. I tried a different way to send mail. This is supposed to send text without all the redundant html coding. Is it any better?

[linux-audio-user] Re: Problems with kernel 2.4.21 and mounting CD-ROM devices.

by Luke Yelavich

Hi all I have sort of resolved it. My default distro configuration, from Slackware 9 compiles ATAPI CD-ROM support, the main SCSI support, and the ISO9660 filesystem into the kernel. I usually make these as modules, to make the kernel a little smaller and thus use less memory. If I leave these options compiled into the kernel, there is no problem. However, if they are all as modules, it doesn't work. DMA is enabled by default, and my DVD-ROM drive is set up to be mounted from /dev/cdrom which is symlinked to /dev/scd0 when using SCSI emulation, and /dev/hdc when using straight IDE. I usually have SCSI emulation set up for burning. This has never been a problem for me in previous kernel versions. I will live with it now, as I guess it is a small kernel size increase and should not change the performance in any great deal. Thanks again Luke

[linux-audio-user] Re: 2.4.21 lockups

by D. Sen

Yes, on my laptop....(IBM Thinkpad T30) I experience lockups (Kernel -oops once in a while) during bootup. It seems to be the ide-scsi module thats causing the problem. If I ensure that its not loaded during bootup then it seems to be fine. I can load it later manually using 'modprobe -a ide-scsi' If you can figure out whats causing this....it will be much appreciated.

by Luke Yelavich

Ok, I have it all worked out now. Just a few options in the kernel that weren't set right. Thanks anyway Luke

[linux-audio-user] Problems with kernel 2.4.21 and mounting CD-ROM devices.

by Luke Yelavich

Hi all. I am wondering whether anybody else has experienced lock-ups when trying to mount a CD-ROM device using kernel 2.4.21 with low latency and preempt? I have tried with SCSI emulation, as well as normal IDE. I am currently re-compiling without low latency and pre-empt, but wondering whether this is a reported kernel problem, or a problem that these patches may have introduced? Any ideas or suggestions are welcome. Regards Luke

[linux-audio-user] recording multiple input audio streams

by Hirendra Hindocha

Hi, I'm looking for solution where we can record multiple input streams of audio to individual files which can then be processed by other programs on Linux. I've searched the ecasound list and also the archive of this list. The best I could find was a similar requirement by someone using a Delta 1010 card. One of the solutions that was proferred was to use the JACK audio server. Is it possible to connect multiple input streams of audio (think multiple phones or line-in from multiple VCRs or any audio device) and individually record the streams as a digital file ? For example - 911 calls , or financial transaction calls etc I'm looking for a Linux based solution that can do that - Ideal would be - a. Well Supported card that has multiple line-in ( so if I want to record 8/16 audio inputs, it should have 8/16 line-in sockets) b. Software to record the line-in audio c. Software to encode it if b & c can be combined to record and encode like ecasound, it would be perfect. I asked around on the ecasound list and was directed to this list. We're not looking to do any mixing or sound editing. Our requirements are very simple. Ecasound works very well for us when using one sound card. We now need to scale this solution so that we can record the equivalent of 8/12/16 sound cards each having an instance of ecasound recording and encoding. A similar solution on the Windows platform seems to be http://www.dictaphone.com/products/freedom/freedomps/ Any help is highly appreciated, -- Hiren ----------------------------------------------------------------------
