XII, an Experimental AudioVision App, performances ,in real-time, 3D computer graphics --animations visualized by audio-- and music based on Twelve-tone technique, running on both iPhones and iPads.
Note: The music in XII is not pleasing to the ears !!!
XII would lean towards automatic composition and music generated automatically. XII, therefore, offers few interfaces for users. Although, XII still provides you with sequence setup UI by which you are able to set the sequence of Twelve-tone.
One way to associate with your works is to send midi notes from the App to your hosts, such as DAWs, via wifi midi supported in XII.
This version performances with piano sound.
The system inside XII automatically calculates the fundamental elements of music, including octave notes, duration, velocity, polyphony, tempo, structure and expression, all of which ,except the sequence, are always generated and never repeated. Please note that all of these features and functions are in the hidden layers.
There are two kinds of sequencer orders under the system, forward and reverse.
---Interactive:
Notes produced by your taps.
3D graphic rotated by your gestures.
---Features:
-lighting
-real-time calculation on both animation and music
-sequence setup.
-background audio.
-wifi-midi feature supported.}
