[linux-audio-user] programmable dsp box?

by Will Benton

Hey, all. I was just browsing and saw the Soundart Chameleon, which looks like a really cool toy. Unfortunately, the development tools are windows-only. I'm sure that I could run at least some of them under wine/vmware, but I'm not too interested in 1. buying a Windows license to get DLLs that I need to run some program properly under Wine (or at all under vmware), or 2. paying $700 for a hardware device from a company that refuses to support Linux or release the code for their compilers (especially since their business model is explicitly stated as "give away compilers for free, so people will make applications and we can sell chameleons"). My other concern is that I'm going to buy a powerbook soon (probably dual-booting OS X and Linux), so having an open-source toolchain would make it much less painful to switch back and forth between my big computer and my portable. Finally, it's been 7 or 8 years since I've done any software development in a Windows environment, and I don't think I could go back without a lot of pain, now that I'm so used to having the standard Unix tools. (Yeah, I know about cygwin/etc, and I'm not trying to start another Linux/Windows flamefest :-) What other programmable dsp boxes (preferably using the gcc toolchain) are there? I'm interested in something like the Chameleon, a rackmountable box with a DSP engine, LCD, control knobs/buttons and audio and midi ins-and-outs. Obviously, the "rackmountable" requirement is least important, but it would be nice, since there's a lot of cruft on/around my desk in the basement. :-) best, wb -- Will Benton <willb(a)cs.wisc.edu>

Re: [linux-audio-user] strange problems with snd

by Bill Schottstaedt

> Incidentally, now that it's working, is there a way to make the fonts bigger? There are too many ways to do this! I use either the ~/.Xdefaults file with lines like: snd*axisLabelFont: -adobe-times-medium-r-normal-*-18-*-*-*-*-*-*-* snd*helpTextFont: 9x15 or the init file (~/.snd) with similar stuff: (set! (axis-label-font) "-adobe-times-medium-r-normal-*-18-*-*-*-*-*-*-*") (set! (axis-numbers-font) "9x15"))) You can use the same init file with gtk (which has a different font naming convention) -- see grfsnd.html for details.

[linux-audio-user] Help! screenshots please.

by Steve Harris

Hi all, I'm trying to put together some content for the proceedings of the Modular 2002 conference, where I spoke about the state of Linux Audio, but I need decent screenshots for Muse, pd and Noteedit, none of which I know well enough. Ideally screenshots should be <= 1024x768 - 600x400 is ideal. Obviously anyone who provides shots gets mentioned in the acnowledgements. Slighit problem is that I need the shots ASAP, I need to submit the content in the next 2 hours. Cheers, Steve

Re: [linux-audio-user] strange problems with snd

by Bill Schottstaedt

I can't resist posting this hack, though I doubt it's actually useful. In response to the Snd font problem mentioned earlier, I wrote some xm-module-based code to show what fonts a given widget is trying to use: (define (show-font-name font) "(show-font-name font) shows the Snd-related name and the X-related name of each font \ in a widget's font list" (define (show-next-font context) (let ((next-font (XmFontListGetNextFont context))) (if (car next-font) (begin (if (XFontStruct? (caddr next-font)) (snd-print (format #f "~A: ~A~%" (cadr next-font) (XGetAtomName (XtDisplay (cadr (main-widgets))) (list 'Atom (cadr (XGetFontProperty (caddr next-font) XA_FULL_NAME)))))) (snd-print (format #f "no font found!~%"))) (show-next-font context))))) (let ((context (XmFontListInitFontContext font))) (show-next-font context) (XmFontListFreeFontContext context))) So, if it's the minibuffer that's giving trouble: (define (show-minibuffer-font) "(show-minibuffer-font) shows what fonts are associated with the minibuffer" (show-font-name (cadr (XtVaGetValues (list-ref (sound-widgets) 3) (list XmNfontList 0))))) If the font name looks ok, try C-z (in the new version), and send me a description of what you see.

[linux-audio-user] Unresolved symbols..

by Saurabh Nanda

Hi, I dloaded alsa 0.9.0rc3 I have a custom built 2.4.7-10 kernel My kernel sources reside at /usr/src/linux-2.4.7-10 and my kernel modules at /lib/modules/2.4.7-10custom I have a CMI8738 I used the following set of commands: ./configure --with-kernel=/usr/src/linux-2.4.7-10/ --with-moddir=/lib/modules/2.4.7-10custom/ --with-cards=cmipci --with-sequencer=yes and the regular make and make install. during make install a lot on unresolved dependancies show up. I am unable to insert the snd-cmipci module due to these unresolved dependancies. any clues to what could be the problem? One more question... will i be able to play sound from multiple sources (without using arts/esd) with the alsa drivers. Thanx, Nanda

Re: [linux-audio-user] strange problems with snd

by Bill Schottstaedt

On the Lesstif/Motif business, you can find out which library is loaded with ldd snd. There's a --with-motif-prefix configure switch if configure is finding Lesstif instead of Motif. I've also noticed the empty-box-where-glyph-should-be-bug even when all the correct fonts are loaded, but I was putting off looking into it -- there's always the hope that no-one else would notice... I'm told that someone is making a real effort to fix Lesstif, so maybe it will be usable someday soon.

> Btw, is Guile 1.6.0 now the recommended version for building Snd ? Yes; the CVS version (1.7) is also good.
