An envelope generator is a device that produces an envelope voltage. When it controls a VCA these together form an envelope shaper.[1]

AD envelope generator

The envelope generator is usually triggered by a gate signal from the keyboard.[2]

Usage

For shorter envelopes at higher pitch, as happens in acoustic instruments, a master CV is taken from the same voltage as used for VCO pitch.[3]
