Envelope:

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....

The CS-05 is a single oscillator monophonic synthesizer with a 3 octave, 37-note (C-C) keyboard. the voice architecture consists of a single VCO, a VCF, a LFO, and a simple envelope generator. The VCO (Voltage Controlled Oscillator) has sliders controlling the level of it's two waveforms, sawtooth, and pulse. The pulse width can be modulated by the LFO (Low Frequency Oscillator). The LFO features a sample-and-hold setting and can modulate up into the audio range for FM sounds. There is an input and a trigger circuit which allows you to trigger a sound via an external audio signal.
