squares
for
interactive music & image processing system
Program Note:
squares
is an electro-acoustic work composed by V.J. Manzo. It was originally
performed with the squares
interactive music and live image processing system also
created by Manzo. The system uses the Korg padKontrol’s 16 touch-sensitive
pads to begin generating algorithmic composition processes when touched.

The velocity of each pad sets the initial velocity of the process.
The system takes live video input from two sources. In the original performance, two cameras were used: one on the performer’s hands, and one on his face. The number of pads currently held down relates to the number of rows and columns used to display the matrix input from the first camera. Each of these squares contains a scaled-down image of the overall matrix. The each square is tinted to resemble the second input matrix, the second camera. Each pad is also assigned a color that, when pressed, causes the matrix color to change. The performance begins (fades in) with the touch of a single pad. If no pads are being touched, the video fades to black (this is subsequently how the performance ends).
The performer specifies an initial mode. The first knob at the top of the padKontrol controls the chord root and quality which drives the algorithmic composition processes. The second knob controls the change to another mode related to the initial mode sharing six of its seven pith classes.
The padKontrol’s XY pad is used to play a monophonic melody in which the X value controls pitch classes of the specified mode, across a 2 octave range. The Y value controls velocity; a position held closer to the top will yield a higher velocity value. When there is no position held on the XY pad, the velocity will equal zero. This, therefore, yields a note-off state when the XY pad is not in use.
A sustain mode can be enabled by pressing the HOLD button on the controller. This will cause notes played on the XY pad to sustain until another XY coordinate replaces it. The velocity (Y) will only change when a new note is triggered.
This video was
generated in real-time from within the software system and was not edited in
any way.

Optical
String
for guitar &
interactive music system
Program Note:
Optical String
is a single-movement reactive piece for electric guitar and computer. The
electric guitar is necessary for the direct string synthesis which is created
with the use of an e-bow. The computer part is played from a sound source such
as a laptop or may be performed live with my original color-tracking,
pitch-generating software:
Lazy Guy.
Lazy Guy is an interactive music system which, for this performance, tracks
the color of a laser pointer in order to generative pitches in a desired mode.
This piece was a participant in the Musica Nova 2007 International
Electro-acoustic Music Composition Competition held by the
Society of Electro-acoustic Music of the Czech Republic (SEAH).

Projects & Technology section for information
on the
Lazy Guy program.

Monochrome
interactive music system
Program Note:
Monochrome
is a single movement work performed on the
composer's interactive music system of the same name. The
Monochrome
interactive music system takes user input from a graphic tablet
(such as a Wacom tablet) and maps pen pressure and orientation to velocity and
pitch. As the canvas becomes filled, more instrument timbres are added and the
modal direction shifts via the
Modal Object Library of algorithms.
Visit the
Projects & Technology section for information
on the Modal Object Library
algorithms.
