OboTek (Piet Van Bockstal, oboe)
This piece was the first interactive computer
piece for an instrumental soloist written within the <GMT>(*)
framework in 1998. Added musical parts are generated and calculated
in real time by the computer and are a complete function of
the players input and its past. One layer of sounds is derived
from the private context of the performer: sounds related to
normal maintenance and non-musical handling of the instrument:
scraping the reed, opening the zipper from the case, testing
the reed etc�. These sounds are recorded prior to a performance
and installed as samples on the computer. During a run of the
piece, the computer reacts to recognition of score material
by playing these samples. Thus the player is immediately cued.
Other voices are -after application of counterpoint procedures
(inversion, mirroring, augmentation, diminution, transposition�)-
played using a variety of instrumental midi sounds. Score and
performance details can be found at: www.logosfoundation.org/scores_gwr/obotek.html

E10 (Tom Pauwels, guitar)
This composition written for guitar is the only
piece on this album not to use any form of electronics. It was
written in 1976 at the request of Peter Pieters, who died in
1998. The title refers to the special scordatura used in the
piece: strings are tuned such that all strings can be made to
sound E.
3.
Cohiba (Karin De Fleyt, flute)
This flute composition is in fact a duo for
a soloist, where the other performer is the computer, trying
to recognize patterns proposed to the player by the score, and
deciding on the course of the piece in function of these recognitions.
All musical voices added to the solo flute part, are calculated
in real time by the computer program for <Cohiba>. This
program was written in the composer's own programming environment:
<GMT> (*) for the PC, in 1999. It was commissioned by
Karin De Fleyt, devoted to the newest musics for her instrument,
and who wanted a piece extending the possibilities of the instrument,
far into the realms of live electronics. More extensive notes
can be retrieved at: www.logosfoundation.org/scores_gwr/cohiba.html

Dynamo (Tom Pauwels, electric guitar and home trainer)
An eco-political piece, in many respects. Conceived
in 1977, the piece was only realized, worked out and premiered
in 1998, in the November Music Festival. Pop musicians pride
themselves to be in touch with society. Their concerts however
are only possible by the grace of a gigantic commercial industry.
In this piece, Raes attempts to confront the performer on the
electric guitar with the ultimate consequences of imaginary
ecological politics. The performer has to produce his own electricity
required to power his amplifiers. As the piece gets more difficult,
production of the power required gets problematic... (Luk Vaes)

Partition (Andrew De Masi, clavichord)
This piece was written in 1976 for the first
clavichord player ever to specialize in new music for the instrument:
Annette Sachs. It was premiered the same year in Teheran. There
are three layers of sound/score, all to be performed by the
clavichordist. Two layers should be recorded beforehand and
one played live. Further notes can be found at: www.logosfoundation.org/scores_gwr/partition.html

LickStick (Tomma Wessel, recorder)
Like 'Obotek' and 'Cohiba', this composition
is a duo for a soloist. In this case though, the score is no
longer a more or less linear list of instructions in time, but
much rather conceived as a game. The player is free to move
through the score in any order, but as soon as the computer
recognises any of the propositions given in the score (appearing
on the computer screen) , it will adapt the score and propose
different alternatives, derived from the musical context of
the moment and of the history of the piece. The piece was written
in the year 2000 for Tomma Wessel, who commissioned it.
(*) <GMT> GMT is a programming
environment written by Godfried-Willem Raes specially for real
time algorithmic composition. It behaves as a superset of Basic
and uses Power Basic's super fast and efficient Basic compiler
(PBDLL compiler). Real time audio processing, complete real
time midi support, granular synthesis as well as treatment of
musical syntax and musical pattern recognition are amongst the
most striking capabilities of the system. People interested
should check the appropriate links on the Logos Website. (http://www.logosfoundation.org).
The complete package is public domain and is available in zipped
form from the site. Supported platforms are: Windows98, Windows
Millennium and all Windows NT versions including Windows 2000.
