Synth Glossary

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....

Very early VCS3 (pre-Putney), note Oscillator 1 The original portable synthesizer introduced in 1969 had a solid Aformosia cabinet which housed the following modules interconnected by means of a matrix patchboard.

3 x Voltage Controlled Oscillators.
Noise Generator.
2 x Input Amplifiers.
Ring Modulator.
Voltage Controlled Low Pass Filter.
Trapezoid Envelope Generator.
Voltage Controlled Reverberation.
Meter.
2 x Stereo Output Amplifiers.
Joystick.

The VCS3 had:3 Voltage Controlled Oscillators, a Noise Generator, 2 Input Amplifiers, 1 Ring Modulator,1 Voltage Controlled Low Pass Filter,1 Trapezoid Envelope Generator, a Voltage Controlled Reverberation unit, 2 Stereo Output Amplifiers and a Joystick. Routing the various functions of the instrument was done via a small pin patchboard.
