An electronic musical instrument that uses sound generating elements (such as oscillators or the like) to create audio waveforms. These waveforms are then combined with others and/or manipulated in specific ways to “synthesize” a unique sound character. Over the years many, many different types of synthesis architectures have been developed and used. Of those a relatively small number have become popular and seen widespread usage. Many modern synths provide digital control over analog parameters, such as frequency, amplitude, filtering and so on to create different timbres. Some generate these waveforms digitally.
