Basic Waveforms of Synthesizer: Pulse Wave
A square wave is a kind of pulse wave, which is basically composed of pulses. (Pulse wave with 50% width = Square wave: refer to the Top picture ↑) The method of adjusting the width of the pulse wave to transform a tone was a common technique in vintage synthesizers.
- By adjusting the Pulse width, you can get rich analog strings or pad sounds
- The way to modify a sound by adjusting the width of the pulse wave is to modify the sound by adding a phase to the sound without adding a layer of multiple waveforms
- A synthesizer with a digital oscilloter can run variables of Pulse width, and the pulse width cannot be modified with sampling waves only
