Hi,
I am interested in the programm "Arno" by Torsten Anders, it is a
extension of cm. So I tried to install cm and I got Grace. Grace is
fantastic and I am going to work with it, but i have no idea how to get
Arno in Grace running.
Has anyone experience with it or ideas?
Alan
P.S.: I attached the INSTALL-description by Anders, it is from around
1999...
To run ARNO you need the following programs:
- a Common Lisp compiler (ARNO is testet under Linux with Allegro Common Lisp
by Franz Inc., see "www.franz.com", and under MacOS with Macintosh Common
Lisp by Digitool Inc., see "http://www.digitool.com/";)
- Common Music. See "http://ccrma-www.stanford.edu/CCRMA/Software/cm/cm.html";
- Sceamer. See "http://www.cis.upenn.edu/~screamer-tools/home.html";
First you have to install the Common Lisp compiler. The order of the
installation of Common Music and Screamer doesn't matter, but both must be
installed before ARNO. For the installation of the compiler, of Common Music
and Screamer see its documentation.
To compile ARNO please edit the path in the file compile-arno.lisp. Find the
line
(setf *arno-dir* "/home/t/lisp/...")
and put the full path of the program there. Evaluate the file. Your compiler
should notice some compilation and after that you should find the *.fasl (or
whatever extension) files in your dir.
You have to do this only once. To load ARNO please edit first the path in the
file load-arno.lisp. Again find the line
(setf *arno-dir* "/home/t/lisp/...")
and put your path there. Evaluate the file every time you want to load ARNO
into your Lisp compiler.
If your got an error you perhaps have to chance the extension (".fasl"
defaults for acl and MCL) of the compiled files in the line
(dolist (path (add-exension cm::*arno-files* ".fasl"))
(load path))
If this doesn't work either please contact:

Arno is a program for computer assisted composition which extends Common
Music (CM) by means of constraints programming using Screamer.
Constraints programming allows a composer to synthesize a score by describing
it. The composer defines the constraints, in other words, the properties
which the result of the program must fulfil. The program searches
for a solution to satisfy the given constraints. Constraints programming
thus frees the composer to concentrate on what he wants to do musically.
The how is left to the computer.
The composer can describe the desired musical result from various viewpoints
on the score such as --- traditionally speaking --- harmony, voiceleading
or instrumentation. Arno does not however bind the composer to any
specific musical style.
In Arno the desired content of a CM container can be declared
nondeterministically
using finite domains. For all parameters of the CM elements in that
container a finite domain (instead of single values) can be declared,
including the rhythm, the note, or any sound synthesis parameter.
Any domain can contain any values or even expressions. After the program
search, each parameter of each CM element is bound with one value
of its domain which fulfils all its constraints. Hierarchic structures
of CM containers in containers can also be declared.
In Arno, constraints are expressed as predicates which test one CM
object. Various functions are defined to easily express relations
between objects. Functions exist, for example, to reach all predecessors
of an object (in the same CM thread), or to reach all simultaneous
objects (in the same CM merge). Further relationships can be defined
using the CM API. These relationships can be constrained using any
parameter of the objects.
The program performs a backtracking search. Heuristics for value ordering
in the domain can also be used. For the sake of performance, backjumping
has been implemented. A dynamic CSP variable order is projected.
Arno is the result of my diploma thesis. I did it mainly for my own work,
but if someone else may need it...
