high speed USB audio device

by Tor Håkon Gjerde

Hello! I am trying to build a high speed usb audio hardware device that will work using existing audio class drivers. I can get it to play in synchronous mode but i really want to use adaptive synchronization which gives the following kernel error cannot submit syncpipe for urb 0, error -90: internal error I cant seem to figure out what i am doing wrong. Some hints would be of much value to me. -- thg

by Fons Adriaensen

Hello all, I'm Running F10 and I have these lines in /etc/modprobe.conf: options snd cards_limit=4 alias snd-card-0 snd_intel8x0 alias snd-card-1 snd_mpu401 alias snd-card-2 snd_ice1712 options snd-card-0 index=0 options snd-card-1 index=1 options snd-card-2 index=2 but the order of the devices is always the inverse: ice1712, mpu401, intel8x0 What am I missing ? Ciao, -- FA Io lo dico sempre: l'Italia è troppo stretta e lunga.

making 'whysynth' microtonal/tuning-table capable

by Aaron Johnson

Hi all, As a big fan of alternative tuning systems and microtonality, the desire naturally occurs to me to seek out synthesis tools which make this possible. I also happen to think 'whysynth' is a nice application whose general felxibilty and sound make it worthy of having some of the more microtonal-aware capabilities of for example, "ZynAddSubFX", but it seems that zyn is no longer in active development, and is sometimes oddly bug-ridden and unstable. So, after having located the code snippet in whysynth that creates a standard 12-equal tuning array, called 'y_pitch', as factors relative to 440HZ (A440), and indexed by MIDI note numbers. I wonder, how easy would it be to make this table dynamic and subject to for example, loading a SCALA .scl file, or at least, a user defined array which can be loaded from a dialog box? here's the code snippet from 'whysynth_voice_render.c' /* MIDI note to pitch */ for (i = 0; i <= 128; ++i) { pexp = (float)(i - 69) / 12.0f; y_pitch[i] = powf(2.0f, pexp); } My GTK experience is nil; my programming chops are strong in Python and TkInter, but not as strong in C/C++....perhaps someone who might be interested in such a venture could point me in the right direction, or be of some assistance?

[OT] gdm setup in F10

by Fons Adriaensen

Just installed Fedora 10. It comes with Gnome as the default desktop of course. Previous versions of gdm at least allowed me to select just WindowMaker, but the option has been removed, as well (AFAICS) gdmsetup. So will F10 allow me to use WindowMaker without having to hack some deep internals ? If not I'll just revert to F8. And if this trend continues I could as well forget about Linux and use Windows. Is there any Linux distro left that does not depend on all the *Kit crap ? Ciao, -- FA Io lo dico sempre: l'Italia è troppo stretta e lunga.
