- Hi fellow composers!
-
- I want to (mis-)use this space (?) to mention, that the composition computer
- language Symbolic Composer is just out in a new release. Originally, this
- package was available for Atari only, but now a Mac version is available, too.
-
- I have used this package to build my submission for the MUSENET project this
- year. If and when you will hear this, please bear in mind that I had the
- program only for about a month then.
-
- OK, so what is this all about??
-
- Symbolic Composer is a computer language, based on Lisp, that allows you to
- contruct music in a very high-level, abstract way. A short example will
- make things a bit more clear. Suppose you want to write out a short scale
- of one octave, from c3 to c4 in the key C major. We all know how to write
- it on music paper, but here is what you do in Symbolic Composer:
- Note: a line preceded with the %-symbol is comment.
-
- ------ Program begins below -----
-
- (setq symbols '(a b c d e f g ))
-
- (def-instrument-symbol
- piano symbols
- )
-
- (def-instrument-length
- piano '(1/4)
- )
-
- (setq tonals (activate-tonality (c major 3))
-
- (compile-song d:!\songs\example 1/1 separate
- % BARS 1---5
- scale tonals .
- piano scale -----
- )
-
- ----------------- END PROGRAM
-
- When you compile this, admittedly too long example with Symbolic Composer,
- a MIDI-file is created in d:\songs called example.mid that has a scale
- played with quarter notes. The process works basically simple: the symbol
- 'a' is mapped on the first note of the "current" tonality, c-major in the
- example above, which is here C. The symbol 'b' is mapped on the second
- symbol, which is D, and so on.
- Now, when I change the tonality to, say 'chromatic f# 3', the same program
- creates a chromatic scale starting on F#3 of seven notes long.
- Of course SC offers much more. Here is the press release of the new release:

- PRESS RELEASE
- 21 OCTOBER 1992
-
- TONALITY SYSTEMS ANNOUNCES SYMBOLIC COMPOSER, EXPERT SYSTEM FOR
- MUSIC COMPOSITION ON THE MACINTOSH AND ATARI. IT IS THE MOST
- SIGNIFICANT DEVELOPMENT YET FOR THE MIDI MUSICIAN.
-
- Tonality Systems has announced SYMBOLIC COMPOSER, Expert System
- for Music Composition on the Macintosh and Atari. The software
- is based on the 6th Generation Common Music Language (CML).
-
- The SYMBOLIC COMPOSER is designed for composers and producers
- working with TV, film, ambient and electroacoustics, giving them
- the ability to realise large-scale and complex projects and
- develop new composition strategies using a set of high-level
- fractal routines, generators, processors, visualizers and neural
- networks.
-
- Mr. Peter Stone, Founder of Tonality Systems and designer of the
- 6th Generation Common Music Language, commented "This system is
- a breakthrough in MIDI production technology, since it unifies
- the traditional composition techniques with the latest
- discoveries of Artificial Intelligence, and is compatible with
- all current state-of-the-art MIDI sequencers and scorewriters,
-
- like Mac's Finale, Performer, Vision, Professional Composer,
- Encore, Cubase, Mastertracks, Beyond and all the others. In
- Atari it is compatible with Cubase, C-Lab Notator and Dr.T's
- KCS."
-
- Mr. Nigel Morgan, composer and music educator commented
- "SYMBOLIC COMPOSER is a truly remarkable and challenging system.
- It catalyses you into discovering new ways to think, imagine and
- interact with your music. Its detailed and authorative manual
- provides a way into serious programming without having to leave
- your music behind for a moment".
-
- The composition is written in the 6th Generation Common Music
- Language (CML) using fractal generators, vector and symbol
- processors, digital synthesizers, library managers and neural
- networks to describe musical parameters. The language is very
- economical and elegant, and even the most complex compositions
- take only few kilobytes when written in CML.
-
- When the CML file is converted in a MIDI file, the corresponding
- MIDI file size is in the range 100-1000 kilobytes, which
- indicates the efficiency of the CML language. The MIDI file can
- be played with all MIDI-compatible sequencers and scorewriters
- in full multitasking environment, and improvised MIDI files can
- also be loaded into SYMBOLIC COMPOSER for further processing.
-
- CML is the most powerful programming language for music yet
- developed on a computer. It contains a full range of high-level
- composition tools that are effective for any type of music. As
- all data is processed symbolically the same operations can be
- applied to different musical parameters, making the language
- extremely powerful and composer-friendly. The system is easily
- extendible using programmable neural networks or the underlying
- Lisp language, allowing the composer to explore the musical
- possibilities of stochastics, astronomy, physics, mathematics,
- genetics or other areas of his/hers special interest. All
- compositional data can also be easily visualized before mapping
- it onto musical parameters.
-
- The built-in generators include among the others Lindenmayer
- L-system, a system developed to model the growth of plants,
- Brownian Generator, nature's very own randomizer, Lorenz
- Attractor, the basic chaotic equation of Gaia, and Associative
- Generators&Neural Experts that model the natural
- associative/logic thinking process of the human mind.
-
- SYMBOLIC COMPOSER has already generated a lively interest among
- experimental composers working with MIDI systems and is
- currently being evaluated by the universities and studios
- worldwide. Its open architecture and multitasking capabilities
- make it an attractive tool for composers exploring the far
- horizons of multimedia and virtual reality.
-
- SYMBOLIC COMPOSER is available in USA, UK and GERMANY through
- dealers specialised in MIDI equipments and software.

-
- DISCLAIMER: I have no connection with Mr Stone, but I am a satisfied
- customer. I have the Atari version, but the Mac version is much easier
- to work with (I have seen it!).
-
- I hope I haven't offended nettiquette too much in posting this.
