[microsound] Electroacoustic techniques

There is a good text by Boulez that touches on this: "A la limite du pays
fertile", published in the book "Relevés d'apprenti". The english version of
the book is called "Stocktakings of an apprenticeship".

The problem is one of precision. Trying to compose in a traditional way on
the computer requires absolute precision (of intent, of process, of anything
that is measurable) and that in turn requires a level of detail that is
automatically understood when you notate for a traditional instrument--plus
the traditional instrument has a richer spectrum and modes of play that are
difficult to achieve on a computer without a lot of preparatory work. It is
far easier to notate a ppp col legno or sul tasto in a score than it is to
prepare the samples or physical models that give you the same result. You
could argue that you can prepare a whole library of sound samples or build a
suite of generators in your favorite synthesis program; I find that getting
them to sound "organic" and to avoid a certain "sameness" takes a lot of
effort, on top of building the library and tweaking the generators.

I did use csound in one of my pieces, however 1) I only used the
analysis/resynthesis capabilities and 2) I used acoustic sounds as source
material. The rationale was precisely to avoid getting bogged down in the
details of trying to get the organic character through purely synthetic
sounds. The piece is "Menons klagen um Diotima", if you're curious to check
the end result (link on my signature).

Hope this helps,
