I don't have an emu10k1/SBLive, and I have very little spare time to work in more projects. And although I've advocated for Pascal, I don't think it is a good idea in this case to port this code. This program is based on several libraries property of Creative Labs, and shipped with the windows software for his SBLive card: SFEDT32.DLL, which allows soundfont edition, and SFMAN32.DLL which also manages soundfonts, I guess. I've seen more library references in the code: MYOKENT.DLL and EAPSMAN.DLL among others. Megafont itself seems to be a GUI front-end for the real engines, and a few more. It is a smart front-end, though, which implements a handy way to manage soundfonts. Think of it as something like QSynth for FluidSynth. Regards, Pedro

[linux-audio-user] Jack-Rack Presets ?

by NiXO Beee

Again a silly question but worth the effort : Jack-rack is a wonderful neat thing for treating live input. Lacks some presets using LADSPA plugins though... (think Alien Connection Revalver on windows, for example) Is there some kind of jack-rack presets repository somewhere near, or one has still to be created ? -- [ NiX=O Beee ] -- Au printemps les boys band, les telephones sans fil, et les pulls sans manche.

Hi Geoff, On my way out but here's my latest: [root@stepdaddy studio]# rpm -qa |grep ffmpeg ffmpeg-devel-0.4.9-7_cvs20050418.rhfc3.at ffmpeg-0.4.9-7_cvs20050418.rhfc3.at imlib-devel-1.9.13-21 imlib-1.9.13-21 imlib2-1.2.0-1.rhfc3.ccrma imlib2-devel-1.2.0-1.rhfc3.ccrma With Ardour in sync to jack and as timebase master. Are you syncing with Ardour or another app? I gave muse a quick try last nite but had the same results. Here's xjadeo starting up: [studio@stepdaddy xjadeo]$ xjadeo vts-test.avi Input #0, avi, from 'vts-test.avi': Duration: 00:06:31.8, start: 0.000000, bitrate: 8734 kb/s Stream #0.0: Video: mpeg4, 720x480, 29.97 fps original frame rate: nan length in seconds: 429497 total frames: -2147483648 Maybe I'll try to rebuild xjadeo with the new libs. That shouldn't make any difference though because we just link to the libs. Right? And it didn't make any difference. I am able to play the above file with mplayer. OK, gotta run sound for a childrens theatre/choir production. Talk to you soon, ron --- Geoff Beasley <songshop(a)bizmedia.com.au> wrote: > G'day Ron, > > > I had xjadeo working on RH9 for awhile.

This has to a library issue or something. When you get a moment could you post your imlib and ffmpeg versions. Here's mine: ffmpeg-devel-0.4.9-0.20041110.0.1.rhfc3.ccrma ffmpeg-0.4.9-7_cvs20050418.rhfc3.at imlib-devel-1.9.13-21 imlib-1.9.13-21 imlib2-1.2.0-1.rhfc3.ccrma imlib2-devel-1.2.0-1.rhfc3.ccrma I'm gonna get the ffmpeg to match up. :) Do you know what repository you pulled ffmpeg out of?

If you want to compare notes let me know. I've got a Big Band gig on tonight, but I 'll be back on deck in the studio tomorrow. speak soon Geoff.

[linux-audio-user] xjadeo compile trouble

by Spencer Russell

After some messing around with libavcodec, I got rid of the errors i was getting compiling xjadeo before, only to be faced with more. Now I'm getting: xjadeo.c: In function `open_movie': xjadeo.c:377: error: aggregate value used where a float was expected xjadeo.c:377: error: structure has no member named `r_frame_rate_base' xjadeo.c:408: error: structure has no member named `frame_rate' and a couple more similar to the last 2 on there. Any ideas? thanks, spencer

[linux-audio-user] some new soundfiles on-line

by Dave Phillips

Greetings: I recently submitted another article for my monthly column at Linux Journal on-line, it should show up within the next few days. I wanted to let LA* folks know that I've placed the article's two short example files here: http://linux-sound.org/lj-seq24-examples.html They aren't finished pieces, nor were they meant to be (though I'm liking them enough to maybe work on them some more). I made them as examples of what can be done with seq24 and a batch of Linux softsynths (and one VST plugin). I had an enormous amount of fun doing these pieces, and I want to extend great thanks to Rob Buse for seq24 and Nick Dowell for amSynth. The state of things in our little world is getting to the point where it gets harder to write about the stuff because I'd really just rather be making music with it. Vast thanks to all Linux audio developers for making dreams come true. You guys rock, every one of you. Now if I can just get seq24 working with JACK... ;) Best regards, Dave Phillips

What was the author smoking? It is written in Delphi, a Pascal dialect developed by Borland as an object oriented replacement for his ancient and successful product "Turbo Pascal". There is a Linux version, Borland Kylix [1]. There is also a GPL-licensed compiler aimed to be compatible with this dialect: Free Pascal [2]. And why not to choose any language to develop your programs it the language is suitable for the task? You can use some arguments like the ones in Kernigham's old diatribe [3] against Pascal, followed by the other sacred cow [4]. But Delphi/Kylix and Free Pascal are Pascal descendants without any of the flaws claimed by Kernigham. You can find similar rants against any language, including C [5][6]. Here are some rebuttal facts against Kernigham's arguments. Delphi language has dynamic arrays, where the size is not part of the type anymore (2.1). It has static and initialized variables (2.2). Forward declarations and function prototypes (2.3). It allows *fast* separate compilation (2.4) preserving strong type checking across units. Set types are powerful and large enough, allowing 'set of char' with 256 elements, and type declarations are allowed in a function prototype (2.5). There is a cast mechanism (2.6) similar to Java. It has advanced control flow for loops using break and continue keywords (3). A powerful runtime library allows you the use of all the operating system functions, including I/O (4), you can even use the Glibc library in Kylix and FPC. And finally, you can write ALSA programs using this language [7], which is why I'm writting this article and why it is on-topic in this list.

Re: [linux-audio-user] Please test the RT rlimits patch for audio

by Norval Watson

Hi Jody, I managed to compile a 2.6.12-rc2 kernel on amd64 running pure64/sid. I used Andrew Morton's mm3 patch and your RT-rlimits patch. i installed and rebooted into the new kernel. I got the libpam packages (libpam0g-dev libpam-cracklib libpam-doc) with apt-get from pure64 repository. Already had libpam0g, libpam-modules, libpam-runtime. How do I apply your patch to this PAM stuff. I don't really know where to start. Also, I couldn't find the sources, where should I look? Thanks, Norv
