(1) An electronic device for making sounds, in which the shape and method of construction have little effect on the nature of the sound produced. This wide definition includes: Electronic organs, samplers, drum machines even radio sets etc. as well as those devices which are more immediately recognised as  synthesisers. Some devices, such as the Thérémin do owe their sound, in part, to their construction, and may be considered somewhat "grey" in respect of this definition. (2) A specific case of (1) above, equipped with oscillators, filters, amplifiers as well as modulation sources. Either with a predetermined or more or less programmable audio and control signal path, which can be used as a musical instrument or for sound effects. The oscillators may include the ability to replay digital recordings of sounds, and the whole or part of the system may be implemented using digital or analogue technologies. |
