![]() ![]() To explain this, let's start with the square wave in figure 1. But before showing you some examples of how you might like to use PWM in Thor, let's begin by asking… What is Pulse Width Modulation? Nowadays, this "pulse width modulation" (PWM) is a standard facility on all analogue and 'virtual analogue' synths, and it remains important because of this ability to create rich, chorused sounds using a single oscillator. In retrospect, a more accurate name would have been "pulse waves whose duty cycles (or 'pulse widths') are being modulated by a low frequency oscillator", but how many players would have understood that in 1974? ![]() Much of the appeal of the Korg 700 (for example) was a result of its Chorus I and Chorus II waveforms, but while the word 'chorus' was a good description of how these waves sounded, it didn't tell you what they were. Yet these instruments could, if programmed correctly, sound surprisingly rich and full. ![]() In the early days of analogue synthesis, electronic components and designs were far more expensive than they are now, so manufacturers such as Korg entered the market with simple, single-oscillator monosynths.
