I don't have access to a 64-bit system (yet?), so I can't debug
this myself.  Just reading the code (io.c probably) didn't turn
up anything.  Not sure what to suggest.

Subject: [CM] sprouts & closure in CM
Message-ID: <42A9E2DC.4060204@mindspring.com>

I'd like to do something fairly simple in CM: define a function that 
would place sections end-to-end, starting one section when the previous 
section ends. I can do this by setting a global variable:

(setf glob-ending '())

Then defining the 'collecting' program ...

(define sections (&rest sprts)
    (process (for sprt in sprts
    sprout (eval sprt)
    wait glob-ending)))

... and adding the following line to each 'sprouted' section I'm using, 
so it's passed back to "sections":

finally (setf glob-ending (now))

This is not the most desirable method for obvious reasons -- 
specifically, I'd like this section-length variable to be closed inside 
"sections". Any solutions/other approaches out there? Thanks!

You could chain processes using the 'finally' clause:

(define (foo reps lev)
  (process repeat reps
           output <whatever>
           wait <whenever>
           finally 
           (if (> lev 0) 
               (sprout (foo reps (- lev 1)) 
                       (now)))))

(events (foo 20 3) "foo.bar")

i should probably (re)implement a container like the old Thread class that would
process each subcontainer and generates all items before moving on to the next
subcontainer. the problem is that there is no 'rhythm slot for relative time
values and I havent quite figured out how to fold this into object-time
(absolute) time values. any ideas welcome!

Just guessing here, but isnt this another situation where hooks
would be applicable?  The hooks could be set dynamically in
scheduled processes or anywhere else.

Something aka:

(setf *after-process-events-hook*
      (if (further-processes)
	  #'(lambda (head time start func)
	      (sprout (foo reps (next lev)) (now t)))
	nil))

Ive got no clues how to implement it for now though :-/ I guess
it involves a call inside #'schedule-event, and maybe redesigning
#'defprocess to return objects (with slots such as absolute time)
with easy access to :before or :after methods and whatnot.

I'm not very knowledgeable about containers, but...would this be something
like a flag that makes one "tactus-adherent"? Certain options would only
work in heirarchies of containers where this flag ON. If it is then a slot
would contain the number of beats (or whatever) the (sub) container fills.

I can imagine this making the use/definition of rests, in certain cases a
little more intuitive-- though maybe I'm only displaying my ignorance here.

i think i see what you want to do: so your main process wants to sprout, then
wait until the sproutee stops and "returns" a value, then the main function
continues on using that value to sprout a new process, and so on?
ill have to think about this, currently processes are lisp functinos called by a
scheudler; ie there is no place to return values to.

im thinking perhaps a realtime scheduler might be able to do this more easily,
ie the caller sprouts and then waits for some condition to arise.

you might be able to do what you want using co-routines. In this 
example. 'mus1' and 'mus2' represent different sections of music of 
arbitrary length that is not known ahead of time. The function 'main' 
is a little state machine that sprouts new sections based on a current 
section id and whatever results are passed in from previous sections.

Is this doing what you want?

(defun mus1 (id reps knum)
   ;; section 1 plays chromatic tones as some rate
   (process for i below reps
     with d = (pick .2 .4 .8)
     for k = (+ knum i)
     output (new midi :time (now) :keynum k :duration d)
     wait d
     finally (main id k d)))

(defun mus2 (id reps)
   ;; section 2 plays a high note
   (process repeat reps
     with d = .2
     with k = 98
     output (new midi :time (now) :keynum k :duration d)
     wait d
     finally (main id k)))

(defun main (id &rest args)
   (format t "~%sprouting section ~s"  id)
   (case id
     (0 (mus1 1 10 80))
     ((1 2 3 5) ;; scheduler is running so sprout
      (let ((last (car args)))
        (sprout (mus1 (+ id 1)
                      (between 5 10)
                      (- last 12))
                (now))))
     (4
      (sprout (mus2 5 12) (now)))))

(events (main 0) "test.mid")

Since the announcement above I have added some new things:

* A (very) nice bus system
* Shared variables
* Ladspa
* Support for the intel C compiler
* General functions can be declared in Guile.
* vct and make-vct


I mention this now, because I will probably not implement that many 
important new features in the near future.

Hi Kjetil,

This is all cool stuff, thanks a lot. 

Any chances that OSC would be on this list also. Please forgive my

Rick and All,
When I open a cmio window, the added "gtk_main" lisp process forces an otherwise idle OpenMCL (dppccl) process to keep my cpu occupied steadily between 50% - 80% capacity on my 667MHz, 1GB powerbook, running OSX 10.3.8. What's sucking up cpu cycles is the "(loop doing ...)" inside the GTKLOOP function. That is to say, any such loop construct is similarly cpu-intensive in OpenMCL, and it has nothing to do with the gtk implementation. After killing the gkt_main process, dppccl settles down to a normal < 1% cpu usage.
Since the gtk interface just passes gui info back and forth (I think), I've experimented with having the "(loop doing ...)" statement SLEEP on each iteration, without any noticable ill effects for the limited testing I've done, but I'm not sure what might break or not work at all. (I know it's ugly.)

It appears the smallest SLEEP value for OpenMCL is 0.01 sec, i.e., (sleep 0.01). This sleep call in the loop pretty much frees up my cpu (< 1% ) but drawing the gkt widgets is  visibly slower. 
Putting (ccl::%nanosleep 0 1000000) in the loop appears to sleep about a millisecond. My cpu peaks out at about 5%-7%. This seems to be the best of both worlds.

Is this worth considering at least until a polling technique can be made to work for GTKLOOP on OpenMCL?  My Powerbook has a very noisy, annoying fan which goes on when the cpu is busy so I'm desperate!

Thanks,
George Khouri

was a bust, and already knows C, so why learn Scheme), I decided
it's time to add a "preferences" dialog -- but the ones I've
seen strike me as a clumsy or useless.  Are there any good examples
out there to look at?  Or some better way? I also need to change
the default to make it more obvious which channel is selected, and
probably make "united" chans the default for multi-channel files.
Anyway, any and all ideas in this regard are most welcome.

(I was thinking of some buttons: "I want Dave's way" and "Do it
Kjetil's way"...)

Thanks for the report and the potential fix!  In the best of all worlds 
I could avoid the process and use a timer callback like openmcl has in 
its example code for gtk1. the problem is i cant get it to start up 
reliablly without lots of wierd errors from X. id ask you to keep using 
your nanosleep trick to see what (other) issues might come up. if it 
seems fine and no other solution can be found ill just add it to the 
code.

Subject: [CM] snd on amd64
Message-ID: <Pine.LNX.4.62.0506181231470.393@robpc2.home.org>

Hi,
like xkr47 (Jonas Berlin?), I get silence in channel #2 when loading
files into snd on an amd64 linux box.  The sound files are definitely
stereo (they work fine on my Pentium4 box).  The problem isn't with
the sndlib-related files, because my program that links with libsndlib
accesses both channels in the sound files, as do the sndplay and sndinfo
programs that come with snd.  My guess is that the problem is specific
to the editor as opposed to the file reading code.

Bill, I realize that you don't have a 64-bit machine.  If there's anything
I can do to help debug the problem, please let me know.

Cheers,
Rob Komar

Message-ID: <coppsuejyx7.fsf@pierre.localdomain>

Hello all.

As they stand now Snd and CM use two different 'find procedures.
Snd's is a sample-searcher (in snd-sig.c i think), and CM's seems
to be using the one in guiles srfi-1.

Could one of these be renamed?  My suggestion is to rename Snd's
'find to 'find-sample, as its more specialized then the one in
srfi-1.

With much good-natured help from Rob Komar, I think this
bug is fixed now.  The fix required a small "API" change
to sndlib.h -- mus_sample_t** as the "cm" arg to
mus_file_read_chans|any -- hopefully this won't affect
anyone else's code.

yes i realize its a bit mysterious, ive cc'd its author (David 
Psenicka) in the hopes that he will explain what it is/does.
The CM bridge to it is ready to go i think as soon as his software is 
released.

yes, there will be (several) new tabs at some point, sooner if someone 
other than i adds them im so swamped with things right now and will 
likely be until after the icmc

its an "abstract" superclass of seq.

yes there have been some really interestesting developments lately and 
only because people other than myself have done them. i hope more 
people will contribute their ideas -- its a pd, open source project 
that can only get better if more people contribute.

i will be rolling the tutorials from the ILC conference into cvs in a 
day or so. as soon as the rt and fomus stuff settles down we can 
declare victory with a development release.

Fomus (FOrmat MUSic) is a Lisp program that inputs notational data in
the form of Lisp lists and structures and outputs a file suitable for
importing into a notation program like Finale, Sibelius, CMN, Lilypond,
etc..  The idea is that reasonably intelligent decisions are made
regarding note spellings, note splitting and tying, distribution of
notes into multiple voices and staves, clef changes, ottava signs,
etc..  This way a computer music composer would spend much less time
working on music formatting issues and could see instant, reasonably
notated results.  He would also have algorithmic control over notational
elements such as articultations, slurs, tremelos, text markings...  The
program is being written in a modular fashion so eventually users will
have some choice over how they want various aspects of their notation
formatted (and will be able to contribute their own algorithms).  At the
very least it will offer a vast improvement over what the import
functions in most notation programs have to offer!

The program is still in development but is coming close to an initial
(alpha) release--A CVS for it should appear on commonlist.net shortly. 
At the moment it outputs Lilypond files, but in the near future there
will also be support for MusicXML, CMN, and .ETF (Finale .ETF support
might end up being rather limited), and possibly others.

Message-ID: <20050628132513.7e573e43@localhost>

hi all,

i have some problems compiling sndlib against jack:
ld -r  headers.o audio.o io.o sound.o xen.o vct.o clm.o sndlib2xen.o
clm2xen.o midi.o -o sndlib.a  -ljack -lsamplerate  -lguile -lguile-ltdl
-lqthreads -lpthread -lcrypt -lm -L/usr/lib -lm ld: cannot find -ljack
make: *** [sndlib] Error 1

the makefile tries to link sndlib.a against static versions of libjack
and libsamplerate, although there are only shared libraries on my
machine (checking jack's makefiles it seems, that there is no static
version of libjack available)

is there any workaround for that or a way to disable building sndlib.a
without hacking the makefiles?

thanks in advance ... tim

What version of Snd is this?  I can't see any way that sndlib.a could
be included in the load statement.  Also, -ljack will try to find the
shared version by default, I think.  If the loader can't find it, you
need to add -L/<dir> to the load line, where <dir> has libjack.
I don't know if the jack library has a configuration script -- jack.pc
or jack-config -- if so, I could add it to the Snd configure script
to handle this automatically -- will check.

In any case, remove sndlib.a from that line -- it is not needed.

*****************************************************************************
1.

Snd-ls v0.9.4.3
---------------
Released 30.6.2005

About
-----
Snd-ls is a distribution of the sound editor Snd. Its target is
people that don't know scheme very well, and don't want
to spend too much time configuring Snd. It can also serve
as a quick introduction to Snd and how it can be set up.

Changes from 0.9.3.0 to 0.9.4.3
--------------------------------
-Upgraded various rt-stuff.
-Upgraded various rt-stuff++
-Removed jack_set_server_dir guile-binding from rt-engine.scm, because its
  removed from the newer versions of jack.
-Updated SND to v7.14 from 19.6.2005. Many important changes.

http://www.notam02.no/arkiv/src/snd/




*****************************************************************************
2.

Mammut V0.20
------------
Mammut will FFT your sound in one single gigantic analysis (no windows). 
These spectral data, where the development in time is incorporated in 
mysterious ways, may then be transformed by different algorithms prior to 
resynthesis. An interesting aspect of Mammut is its completely 
non-intuitive sound transformation approach.

Changes 0.18 -> 0.20
--------------------
-Fixed a bug in the Makefile caused by a fix in the previous release.
-Fixed some bugs in the Makefile.

http://www.notam02.no/arkiv/src/




*****************************************************************************
3.

Ceres V0.43
-----------
Ceres is an advanced program for displaying sonograms and for sound 
effects in the frequency domain. And more.

Changes 0.42 -> 0.43
--------------------
-Fixed some bugs in the Makefile

http://www.notam02.no/arkiv/src/




*****************************************************************************
4.

Snd RT-extension documentation
-------------------------------
The realtime extension for SND makes it possible to do signal processing 
in realtime using guile and a special scheme-like compiled language.
It has many features, as jack-support, CLM, a realtime scheduler, 
a compiler, busses, dynamic patching, shared variables, ladspa and more.
It can also be made to work with Common Music.

well, it's not a problem _finding_ libjack ... the problem is, linking
the shared library libjack to the static library libsnd ... 
afaik, you can't link a static library with a shared library ...
