CONTROLLER
LIGHT SENSOR 3
LIGHT SENSOR 4
PLACEMENT
 suspended from the ceiling, about 0.60m high
SAMPLE SOURCE
NYC field recordings (ambient & people)
LIGHT SOURCES
 natural light (twilight) + in-door hanging lamp (can be touched/ moved)
PHYSICAL VARIABLES
 faint of day and/ or people interacting through body shadows and moving lamp
EFFECT ON SOUND
 half-bright / dark = ON; bright = OFF; ON-OFF-ON = playback overlap tuning (down), panning, sample lenght, sample start
FRUITION
 contemplating or playing the soundscape with body and lamp shadow

         NOTE #1:
In Lisa, behaviour-mapping tables convert in-coming MIDI into a larger range of values responsible for the audio processing (127-range ascends to 512-range). MIDI provided by LIGHT SENSOR 3 tends to oscillate fastly by twillight. LIGHT SENSOR 4 - controlled samples turn on and off repeatedly, crossing the threshold occasionally at first, then gradually faster until a peak after which they remain on. This might increase sound density through overlapping layers. In the meanwhile, LIGHT SENSORS 1 and 2 are dissolving the day-soundscape. There is no similar segment in the present audio file.
         NOTE #2:
The present audio file is a mix of raw samples. Their diversing audio-qualities provide a big range of real-time re-sampling and processing possibilities during the night-time situation.
