Week 6: Synth Basics -- Compare the graphical interface of four different synthesizers. Clearly show where the Oscillator, Filter, Amplifier, Envelope, and LFO sections are.
One can find many VST synthesizers on the Internet to download. Many of these have a unique graphic interface where all the effects can be set, but it is a bit time-consuming for one to find out what a single synth is capable of. Modular design is a common feature: on almost every interface you can find an Oscillator (OSC or VCO), a Filter (FLT or VCF), an Amplifier (AMP or VCA) with an Amplitude Envelope (ENV), a Low Frequency Oscillator (LFO), and often additional Effects (FX). ('VC' stands for 'Voltage Controlled' in the beforementioned abbreviations.)
On the following figures you can find the graphic interface of four synthesizers with the different modules marked with different colours. In general these interfaces look like real hardware as they have a bunch of knobs and buttons and faders to fiddle with, but unlike most real hardware they often have little screens to show how the waveform looks like, just like an oscilloscope. Some of them even have detachable wires to connect different modules, so one you can redefine the order of these modules and so alter the behaviour of the synth.

On this site there is a list (under the practical name 'The List') where you can find many free synthesizers to download. You should give them a try if you are interested.
