nil
for
guitar & interactive music system
(2010)
Program Note:
nil is a composition for solo classical guitar and interactive music system.
In this piece, the opening notes of the guitar performance are sampled by
the computer and placed into a small buffer. From within the buffer, the
audio sample is trimmed to remove any silence around the file. The audio
sample is then manipulated to generate all of the computer sounds in the
piece.
As the performer continues to perform from a notated score, the computer
begins manipulating qualities of the audio sample according to a score that
it follows. The computer also processes the live input of the performer in a
number of ways. All of the computer processing and sound generation for nil
occurs in real-time and is driven by the performance of the guitarist;
nothing is prerecorded.

discourse
for
Eb Clarinet & interactive music system
(2009)
Program Note:
Discourse is a piece for Clarinet in Eb and interactive music system. The
original software, which was also written by the composer, takes the
clarinet signal as input and processes the sound in real-time. All of the
processing happens live, so there are no prerecorded sounds in the piece. In
other words, the computer's performance, including its timbre, is data-driven by the clarinet's
performance.
The clarinet begins a conversation with the computer which responds by
imitating the clarinet and expanding upon its ideas. These two voices
continue their dialogue: formulating responses to the other's last
statement, pausing to listen to each other, and even stuttering at times
while trying to answer appropriately.

stitching
for
cello, Eb Clarinet & electronics
(2010)
Program Note:
stitching is a piece for cello, clarinet in Eb, and electronic sounds. The piece was written as part of a collaboration between the Temple
University colleges of dance & music. The collaboration, called the "audio
kinetic project" paired a composer with a group of
dancers/choreographers. The video excerpt below was recorded during the
project's recital on May 2, 2010.

squares
for
interactive music & image processing system
(2008)
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.
more>
hide>
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
(2007)
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).

Lazy Guy program.

Monochrome
interactive music system
(2007)
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.
