Detailed Description

One thing a composition watches, reduced to a byte per tick.

The three drivers that already exist in this class, plus an oscillator. SENSOR is levelSource()'s reader, range, wrap and smoothing; MUSIC is musicSync()'s track and sensitivity; CONSTANT is setLevel(). A composition evaluates each driver exactly once per tick, before any layer runs, so two layers bound to one reading cannot disagree about it within a frame.
