It This program uses the viewers movements brightness tracking in the Video library of Processing to control different sounds track the brightest pixel. Using a song. I would like to use flashlight, the user controls the frame differencing method frequency and utilize the way it quantifies the amount of movement in the video frame to control different parameters/filters amplitude of a songdrum synthesized MIDI notes. Some Simultaneously, a predetermined array of notes plays at random and creates random ellipses that appears on the control parameters are going to be the speed, treble, key, and volumescreen. I’m hoping that this project will create This creates an interaction improvisational live "duet" between what the see on participant and the program. The colors of the ellipses both controlled by the screen user and how their movement affects the song that is playing. It will give way program are generated at random to add a unique dynamic visual experience with a music that does not involve electrical controls, turntables, dance pads or even an actual instrument. But rather, it gives your body some control over the sounds you hear through your own motions.

Uses The flashlight held by the frame differencing methods to capture user will be tracked by the amount brightness tracking method in Processing's video library. The top half of movement in a frame and then send those numbers the screen is designated to Logic Pro the area where the user can control the MIDI notes. Left to right controls the amplitude, while Up and Down control different filters that would then change the sound of the songfrequency. The input would be While the amount bottom half of movement in the video frame and screen is designated to the output would be random ellipses that create a change in sort of rhythmic dance on the sound of screen while playing an improvised melody for the songsuser to interact with. I would split used the frame into quadrants, one for a different filter. An amount of movement also has to be specified Soundcipher library to control the amount changeMIDI sounds. For example, The speed of each drawing of the ellipses as well as the speed at which playing of the participant notes is moving in determined by the quadrant that controls frame rate is by default is set at 6. The user can change the amplitude of frame rate to faster or slower by pressing the song determines how loud of soft up or down button on the song is playingkeyboard.

The flow in of information will go as follows: A song would begin to play and As the user would move and interact with moves the flashlight across the screen. Processing , it will then take change the MIDI note's parameters (amplitude and frequency) while the amount of movement in random ellipses play a melody on the designated quadrants bottom half of the screen . The ending result is an interactive MIDI sound dialogue between the user and send those numbers to Logic Prothe program.
