An envelope generator generates a signal that changes through the length of a sound, normally to control the loudness of that sound. An example of its use is to control the volume of a piano sound. It creates a signal that goes from low to high very quickly (the loud bit when the key is pressed), then goes down slowly as the sounds gets quieter. They are also used to drive other parts of the synthesizer, for example the filter....
Electrocomp 200
The Electrocomp 200 is a 2-VCO monophonic synthesizer expander module. It did not
come with a keyboard but as an expansion module for the 100 or the 101, which
included a keyboard. The Electrocomp 200 features two VCOs, which have outputs for
sine, triangle, and pulse waveforms, and a noise source. There is a spring reverb, a
low-pass VCF, a high-pass VCF, an ADS envelope generator, a ring modulator, a mic
preamp, and a dual 3-channel stereo mixer.
The eml-200 came in 2 colors, blue and silver. The later ones were silver and the
original ones were blue. The blue 200s were also built into larger cases and were a bit
heavier than the more recent silver ones.
