Snd 12.8:

s7: added logbit? (using gmp arg order, not CL)

    added reverse argument (in C) to s7_new_type_x and (in scheme) to make-type.  
      This is needed because an object might implement the apply and set methods, 
      but they might refer to different things (I should have noticed this a long
      time ago).

    s7_environment_to_list and environment->list return just the local environment's
      bindings.  They used to crawl up the environment chain, but that can now be
      done with outer-environment.

    outer-environment returns the environment enclosing its argument (an environment).

    added an object system example in the environments section of s7.html.
      It's based on environments as classes/instances.

checked: sbcl 1.0.55, gtk 3.3.8|10|12

Thanks!: Mike Scholz, Rick Taube.

wow. this this strong enough to implment tiny-clos with call-next- 
method and make-instance?  If that were possible i could load cm2 into  
s7 !

hmm... where's my copy of CLtL2...

(make-instance should be no problem, but I can't remember
how call-next-method actually worked).

guile, gauch, stklos, chicken all support (to one degree or another)   
a variant of cltl2 called tiny-clos that implemnted basic  
functionality of clos

as i recall the stklos doc was pretty good,

http://www.stklos.net/Doc/html/stklos-ref-8.html#STklos-Object-System

also gauche:

http://practical-scheme.net/gauche/man/gauche-refe_64.html#Introduction-to-the-object-system

and 'goops' in guile:

http://www.gnu.org/software/guile/manual/html_node/GOOPS.html

these tiny-clos derivatives didnt have lots of the bells and whistles  
but you could do 95% of typical cltl2 functionality. for example t--  
rather than cltl2's :around :before and :after methods -- these  
systems  let you call (call-next-method) when you want the next method.

i think make-instance was actually called make, ie

(make-instance 'foo)
is
(make <foo> )

and ininitialize-instance is called initialize.

so to implement an after method on initialize you would do


(define-method* (initialize (obj <mysuperclass>) args)
   (next-method)		
   ....)


my cm2 sources are actually written in tiny-clos and works in  these  
shemes. cltl2 sources are autogenerated from the scheme code if you  
load the cm system into common lisp.

Subject: [CM] snd without any graphics system
Message-ID: <20120202095621.297478e8@rene.carmen>

Hi,

Installing audio software on a new computer (Debian 6.0)
I had troubles because I tried to conciliate Alsa, oss etc.
I reinstalled Debian (it was easier then debugging).

But snd has no graphics:

rb at rene:~$ snd --version
This is Snd version 11.6 of 7-June-10:
    s7: 1.58 (2-June-10), Xen: 3.4
    ALSA 1.0.23
    Sndlib 21.2 (11-Dec-09, float samples)
    CLM 4.31 (7-Mar-10)
    GSL 1.14
    fftw-3.2.2-sse2 
    without any graphics system
    LADSPA: 1.1
    gmp: 4.3.2, mpfr: 3.0.0-p3, mpc: 0.8.2
    Compiled Jul 25 2010 20:50:08
    C: 4.4.4
    Libc: 2.11.3.stable
    host: i686-pc-linux-gnu

Is there a way out of the labyrinth?

Best regards,

Subject: [CM] Most efficient way to play a tune
Message-ID: <CAF924D0-B5D9-4CF9-9A33-DA1680C6E091@free.fr>


Hello,

what is the most practical way to "lay out" a tune in CM?

Do you just type a series of send("mp:midi"...)s in your code, with one send per note?
Is there a pattern which allows you to simply play a series of notes, as opposed to making cycles, etc?

For instance, here's how I would transcribe the beginning of Gaspar Sanz's Jacaras:

begin
	send("mp:midi", key: key("d3"), dur: .5)
	send("mp:midi", key: key("d4"), dur: 1)
	send("mp:midi", key: key("f4"), dur: 1)
	...
end

where .5 notes are quarter notes, and 1 notes are half notes.

Is that efficient?


Furthermore, in the CM documentation, the notes function is described as 

"Return[ing] the note (string) of ref, which can be a note, key or list of the same. A note name consists of a pitch class letter (c d e f g a b), an optional sharp or flat letter (s f) an optional quarter tone inflection (< or >)..."

What exactly is a "quarter note inflection"?

Many thanks for your help.

Best regards,

Philippe

Hello,

is choosing SAL over Scheme a matter of taste or is there a real difference?

Can you create instruments in SAL?

Many thanks.

tiny-clos has always worked in s7 -- it used to be a part of
my test suite.  I think you just need to add s7 to the list of
scheme implementations, and add its sort! to the table of sort
variations.  I can send my copy if you want it.

You need either motif or gtk to get graphics in Snd.  In
some cases, you may need the "devel" package as well as
the normal one.  I always build both from the sources,
so I'm not sure how they are packaged.  When you run
configure, it creates config.log that tells what that script
did.  Sometimes it contains more information than the
script printout.  The other possibility is that your gtk
is too old.  I think currently Snd needs 2.12 or later.

It actually says "quarter tone inflection" by which I assume Rick
means a quarter tone change in the pitch, up or down (that is,
half a semitone).  (american?) english uses the same term for 
the pitch change and the duration.
