A Butterfly Flaps its Wings....

for string trio Arabic ud and live electronics (2004) Duration: 7"

Introduction:

A Butterfly Flaps its Wings... designed to be performed as a string trio, Arabic ud and
computer. The computer realized the music live on stage, with performer foot- pedal
triggering system and Max/Msp environment, and create a new musical gestures.
The computer voice is manipulate with the two dimensional Phase-driven oscillator that
using a buffer~ as a Wavetable. The idea is similar to wave~, but with an additional axis.
A given ms range of an audio file will be divided into n rows. The Y phase input will
determine which row(s) will be used for playback.

The pictslider is a slider with the usual one-dimensional ranges of movement, for
emulating hardware sliders Its knob can also can move both horizontally and vertically,
to represent a two-dimensional Controller such as a joystick to control the X phase of the
2d.wave~. In addition the effect section including comb~ object implements a comb filter,
in which a slightly delayed version of a signal is added to itself, causing phase cancellations
and a spectrum that looks like a comb.

The vst~ object loads a real-time VST plug-in and uses its audio processing in MSP.
Some plug-ins has their own Editing window, which is visible when you double-click
on the object. Otherwise, double-clicking on the object displays a Default parameter
editing window. The user can view a Spectrogram or Sonogram Display and a A Signal
Level Meter with Optional Ballistics. The buffer can be played forward and backward
at any given time. The output can be recorded to the hard disk and Levels can be
control including fade in and out.
