I've looked for a Fine Manual on this but no luck:
Jack starts OK with a period size of 512 but with 256 or 128 it seems to
say that the ALSA driver refuses to accept it. Does anyone know, is this
a hardware limitation of the card, or something I can change with a
magic parameter in some configuration file? The card is an old SBLive
Value (the box said something about MP3) and the software is Red Hat 8 /
Planet CCRMA / emu10k1.
If I have understood the Jack documentation correctly, this corresponds
to about a 35 millisecond buffering delay for the round trip of a signal
from the outside world into the computer and back out again. Plus any
time spent processing the signal inside the computer. Not bad, really, I
guess. I wonder what an M-Audio Delta could do?
jackstart -R -d alsa -d hw:0 -p 256 -n 2 -r 44100

Hi everyone!!!
here at the University we have an M-Audio delta 1010 for multitrack recording, have anyone tried to make it work on a debian system? and if so, which sound app would be the appropiate for that matter?
thank you very much in advance and greetings from Xalapa Mexico!!!! AJUUUUUUUUUUA!!!!!!!!!

I thought this may be of interest to some of the folks on this mailing list.
I found it on Newsforge.com.

I am building a Rebirth file player/converter/sequencer.
I am awaiting a response from Propellerheads to get approval if I can
release a public *file player*. Their file format might be copyrighted,
and without permission I can't release it.
If Prophedz give me the thumbs up I will make it public (just the file
player/utils).
It's just simple command line utilities to play Rebirth files on Linux.
It will emulate the sounds, but not the look or feel or editing.
It will have the ability to export to MIDI files, output to WAV, create
Tekno Composer loops/patterns. It just won't let you edit or create new
files in the format. Or, if I can, you can edit new files, but you won't
have a GUI that looks like it. I will find out what Propellerheads say
and how far I can use the file format for a GPL program.
I still like Rebirth, and even though the sounds are old, it is still a
very useful file format and composition program. I made Tekno Composer
so I could at least get something of the way the sequencers worked. The
file format is something I am very interested in, as so many patterns
are available in the format, and it's a shame they can not be used by
any other program right now. There is no copyrights on a pattern I don't
think. That would be silly. That would be like saying I can copyright
the eight note symbol and everyone pays royalties for me to use it in
sheet music. Or copyright a scale and get royalties for anyone who uses
it in their music. I can't see how a pattern out of context can be
copyrighted, but most likely some loophole in the law allows it.
If Propellerheads inform me the file format is not copyrighted I will
work on it as far as I am allowed to. I can't imagine why else they
would release the file format specification. I am also unsure why no one
has at least made a file conversion utility either. I know people have
built emulators (really good ones) but violated copyrights. I missed out
on getting the programs before they were closed down.
I'm not sure how much Rebirth is used these days. I still used it a lot.
It was missing many features I felt were needed It's a very very simple
system for making rhythyms and bass lines with, and so many people have
tried to copy it but it seems almost all of them never got released or
are no longer available. I have tons of work in Rebirth format, so I
need the conversion utilities, but I would like to make them public. It
would also be fun to build a program that can play them back and listen
to them on Linux.

I have the exact same problem, using Planet & Redhat 8.0, same soundcard.
No idea what's wrong either.

Hi,
I have a new Dell laptop with a headphone jack as the only external
audio output. With headphones, the sound quality is good and there is
little noise to be heard. However, if I plug in my monitors, the
output crackles and hums, regardless of the mixer levels. There is
217 hz constant hum, a 125 hz hum when moving windows, and a 689 hz
whine when I run Pd. The output crackles when I move the mouse
(external USB). I just noticed that it goes away when I unplug the AC
adaptor. I think I remember a similar problem coming up on this list
before, but I had no luck searching the archives. How can I solve
this?
Thanks,
Ben
i think you're out of luck...the point of laptop architecture is to squish
everything together....with a monitor and usb (which is fairly high voltage)
so close to an integrated audio card, you cannot avoid magnetic influence as
shielding at this level is practically impossible....you're best bet (and
not a very good solution) is to get a breakout box so the actual dac is
physically outside the laptop. If you come up with better solution please
let me know,its a problem that frequently drives me nuts

Hi all,
I've installed Alsa (latest) and the MuSE sequencer/composer (also
latest). I load one of the example songs in MuSE and when I press the
play button nothing happens, nothing moves on the screen and nothing
plays.
On the other hand, when I move the mouse cursor over the notes in the
piano roll window I can hear the notes on the external MIDI synth, so I
know MIDI works (at least in one way).
But when I press play the cursor does not move. I thought this could
have something to do with the kernel low latency option so I installed
the patch (kernel 2.4.20), enabled some options as in the low latency
HOWTO, recompiled, ran lilo, etc... But now the kernel won't boot.
So, while I'm restoring the kernel to what it was before, has anyone
had the same problem playing MIDI scores with MuSE on an external MIDI
synth ? Any suggestions ?
Sound card is Sound Blaster Live (emu10k1).
Cheers,
Alain
Hi!
Sorry for the english .. :-)
SoundFontCombi takes the advantages of ALSA sequencer and the wavetable
devices for emulate a synthetizer.
I'm not programmer, this program dont have project page, CVS, or mailing
list, is in proof of concept rigth now. And only the binaries are available.
Is my first program in C++, my first graphic program for *nix, and belive
me the source code needs a "making up" rigth now. Maybe next month when i
learned how to do a Makefile :-)
SoundFontCombi was tested in Debian sid and Gentoo.
Requires FLTK v1.x.x (tested on v1.1.1) and ALSA with sequencer.
The binaries are available in :
http://personal.telefonica.terra.es/web/soudfontcombi/sfc-v0.005.tar.gz
Any commets will be apreciated.

Hi Richard,
There must be a way... My SBLive Value can do it directly via the
alsamixer, but my PCI128 (same as yours, I think) doesn't have that
route. I've sent this reply to the LAU list, maybe someone there knows
how to do it ?
Best regards,
