 i'm writing this email, because i'm
interested in what plans the
different linux audio developers have for the year 2005 Any new
revolutionary applications planned? Major changes to some of the
existing apps? So let us know. What are your roadmaps for 2005? What are
you guys up to?

I plan to get my patch adding multichannel support to the emu10k1 ALSA
driver merged, then work on a real hwdep mixer app (probably by
extending ld10k1/qlo10k1).  As many of you know I'm a big fan of these
cards, they are extremely cheap and (with good driver support) perfect
for an entry level DAW, like a portastudio or something.  Anyone who has
used the kX drivers on Windows knows how much potential this device has,
and unfortunately the Linux support is still a joke compared to the kX
driver can do.  But, that is all about to change, as the two crucial
features (the DSP patch loader and "kX ASIO", aka the full duplex
multichannel/low latency PCM device) now exist on Linux.

 oh my god, are you serious? i was using the kx drivers when i was on 
 windows, and i gotta say they were the best thing since sliced bread!!!  
 it turned my soundblaster live platinum into a BEAST of a music machine 
 (well, compared to what it was) ...

Heh, I still use them, all the time.  I have to admit when it's time to
make music I still use Windows.  This is actually what got me interested
in Linux audio, as soon as I realized how far ahead the kX project was,
I quit my day job (was sick of it anyway) to work on this project.  Now
it's 6 months later, I'm a lot poorer, but it works dammit!

...
  when i switched to linux, one of my biggest
dissapointments was the 
 dismal support for the emu10k1 .... especially lack of multi-channel - 
 by multi-channel support, do you mean that you are able to use the rear 
 output channel independently of the front channel (at the moment my 
 front and rear channels are basically inextricably linked)? 
Yup.  If you have the livedrive you can use all those jacks as
independent ports.  My Audigy2 ZS has something like 6 channels of
analog in and 8 out, enough to record a band.  And there's nothing like
zero latency hardware DSP...

I have to admit I still use Windows with the kX drivers when it's time
to make music.  It will be a great day when I can do the same with
Linux.

...
   that is 
 exactly what i've been trying to get happening for a while now, which i 
 need for dj mixing work (so's i can have an independent "preview" 
 channel for cueing music) ....

 the dsp configuration in kx audio was the killer ... are you saying 
 there is support NOW for use of this kind of feature in linux ...where 
 can i get the patch?

I actually got a lot more responses than I was expecting.  I have been
posting about this to the alsa lists for months, and no one but me and
Peter Zubaj seemed to care.  I think they didn't take me seriously at
first, even when I posted the kX stuff, Linux users are conditioned to
think these cards are junk.  Windows people know better ;-)

I will post the patch somethime this weekend.  It would be great to have
more people test it before I submit it to alsa-devel.

In the meantime while I have been focused on multichannel Peter Zubaj
has been working on the DSP part.  Check it out:

  this sounds very exciting to me! 
Thanks, hope it works for you.
