Introduction Use of voltage control amplitude envelopes became standard in the 1960s after they were implemented by Moog on the evolving Moog Synthesizer (1964-1965). In the digital domain the envelope realizes its true potential as a variable function of change over time more akin to the use of lines (stochastic calculus, probability curves, ruled surface)…
