The Rotators are designed to be the unit of
instruments in a rhythm
section for automatic playing. The core section to control the unit is
named Rotatorhead.
The structure of Rotatorhead is same with that of
disk type music box. Set the disc onto the turntable. The disk is made
from vinyl disc and shortend color pencils embedded on the disc's
surface. The uniform rhythm starts, when the pencil hits the switches
attached over the bridge part to turn on/off home electrics plugged
into
connectors.
The bridge part contains 3 tracks. the each switch of each track links
to an electric connector, and that's mean, a rhythm consists of 3
different sounds made up from 3 home electrics connected to the
plugs.
