|
It is often desirable to control musical objects or events as aggregates rather
|
|
than individually. Aggregates might take the form of a series of events spaced
|
|
in time, in which the details of the events follow from the larger arc (for
|
|
instance, notes in a melody). Or the individuals might sound simultaneously,
|
|
as with voices in a chord, or partials in a complex tone. Often some or all
|
|
properties of the individual elements are best inferred from those of the
|
|
whole.
|
|
|
|
<P>
|
|
A rich collection of tools and ideas has arisen in the electronic music
|
|
repertory for describing individual behaviors from aggregate ones. In this
|
|
chapter we cover two general classes of such tools: envelope generators and
|
|
voice banks. The envelope generator automates behavior over time, and the
|
|
voice bank over aggregates of simultaneous processes (such as signal
|
|
generators).
