Actually ... that sounds interesting ... can you post a link to the
article about synchronizing fireflies?
It's from CMJ, but not the one you'd think -- College Mathematics Journal,
vol 37 no 3 May 2006, Fireflies flashing in unison by Ying Zhou,
Walter Gall, and Karen Nabb. The references
After the great disk crash, sourceforge changed all the project names.
In each case you need to start over (i.e. recheckout) the project with
the project name at the start. In snd it's:
cvs -d:pserver:[EMAIL PROTECTED]:/cvsroot/snd login
cvs -z3 -d:pserver:[EMAIL
Probably the quickest is to use the dy function:
(cmn (setf s1 (staff treble (meter 6 8) a4 e a4 e a4 e a4 q.))
(staff (tied-to s1) (d4 q stem-down) (eighth-rest (dy -.75)) (d4 q.
stem-down sharp)))
The argument is in terms of staff = 1.0.
There's a section about the clm-snd connection in clm.html -- CLM
and Snd or something. CLM has various wrappers to start Snd and
open the output of with-sound and so on (clm-snd.lisp). The catch
is that this depends on the FFI and the presence of X11, so it may
not work in your setup. I think
CLM in Snd uses whatever extension language you've chosen, so
in your case CLM is using Scheme. Lisp (Common Lisp) is not
yet supported in Snd. When you run Snd's with-sound, you're running
CLM in Scheme (the CL in CLM no longer means anything).

Not even sure I need this package, as I understand CLM is part of SND
and I intend to use that.
I don't know what the sbcl/clm problem is, but you don't need it
if you're using Snd -- CLM is built into Snd, so just load ws.scm
and whatever instruments you want, annd call with-sound in

I think others have mentioned that that device doesn't
work in Snd -- I don't have one, so it's hard to fix.
I think the error message is trying to say that
there aren't any active output channels (which is
independent of the hardware -- did you activate at
least one output channel?). You also

It's possible now to use Gauche as the Scheme extension language
in Snd: http://www.shiro.dreamhost.com/scheme/gauche/index.html.
--with-gauche is the configure arg. I think I have about a week
or two of work to go -- see snd-xen.c for a list of problems, but
enough works for Snd to be usable.
My first guess is that you didn't load clm. Does *features* mention it?

I think sc.c should work in OSX/openmcl; the problem appears to be that the

Fedora Core 5 goes out of its way to delete Motif (and mwm, which I like!);
to rebuild motif 2.3, you need to replace the two or three includes of
X11/bitmaps/gray (Xm/I18List.c, Xm/IconButton.c) with:
#define gray_width 16
#define gray_height 16
static char gray_bits[] = {

I am on a Mac OS X 10.4.5. I am using snd to record (my voice) with a
microphone and the resulting audio file is very high in frequency.
I am all smiles -- I had never tried the recorder on a Mac -- I'm amazed
it comes up at all. I'll try to find a microphone and poke at it tomorrow.

I think the segfault is fixed now; I also made a few changes to audio.c, pending
Fernando's approval: the default ALSA device is now default, so Snd should
behave more like other players, but experts can still use hw if they want;
the environment variable names now use MUS, not SNDLIB --
Fernando explained what is going on, I think (at least his bugfix works
on my machine). aplay uses the device plughw:0, whereas snd/sndplay
default to hw:0. plughw then provides low-fi sampling rate interpolation
if necessary, whereas hw just throws up its hands. To see aplay in the
same mode
I don't know much about this issue, but perhaps this is helpful:

linux audio lists.

Those are good questions! I fear the answer is no to all three. The thickness
message currently only applies to double bars -- I can't remember why it has
that restriction -- I'll add a bar-thickness, or maybe barline-thickness message
to my TODO list (it should be very easy to add). I thought
I don't know why ALSA is involved at all -- if you include both --with-esd
and --with-alsa, you get esd; my guess is that you've hit an esd bug, and
should report it to them.

cmn's iratify stops searching for a ratio (it uses continued fractions,
so it's very fast) when the error is less than smallest-note --
in this case smallest-note is .015 so
* (- (* .125 9) (/ 10 9))
0.01336
If you set smallest-note smaller (say .001) you'll get 9/8:
* (setf smallest-note
That isn't an error in C or C++ -- the first chans is a field of a struct, the
second is a local variable. What compiler are you using? If possible,

CMN is a Lisp program, so you need Lisp to use it. Clisp is
a version of Lisp, as is MCL. Snd is a separate program, only
loosely related to CMN. I don't know anything about iBooks --
is that an Apple computer? If so, you might be able to use
openmcl.
There must be a way to make CLM's use of random compatible with CM's,
but I haven't taken time to look into it (I'm trying to get Snd 7.18 out the
door).
The clm-random problem is one that I think is a bug in Lisp, but I have no
hopes anyone will agree: 1.0 is not a double float! The clm-random

By zero do you mean zero-crossing? There are several functions to search for
these

to

It currently has the Times-Roman font built-in, so probably it is

The function fft is available in instruments -- see san.ins for example.
In lisp, it's either fft or clm-fft -- see mus.lisp, and ffi-test.lisp.
The spectrum function in mus.lisp may be what you want. There are
lots of other examples -- ug4.ins for example.
All versions of Guile after (including) 1.3.4 work with Snd, although
I assume 1.5 or later in many of the Scheme files. What went wrong?
(In some cases, you have to tell the configure process how to find
Guile -- GUILE_CONFIG_path etc; also I hope Fink includes guile-config).
I added those Mac-OSX switches to the configure script (changing the
weird 'pwd' business to -I.).

I enjoyed your article! On the interface: I've always thought a
tool should be invisible -- you work on something, and if the tool
is appropriate, you only think about the thing you're working on.
But... everyone and his brother has complained about Snd's interface, so I've
been working on it
