Abstract
An acoustic signal generator circuit produces electrical acoustic signals ose frequency spectrum and envelop curve respectively determine the acoustic parameters, pitch and timbre and, respectively, the change in amplitude with time and accordingly the volume, attack and decay phenomena and also quasi stationary behavior of the corresponding sound. There is a manually actuated control device for influencing at least one part of the acoustic parameters. The control device can be constructed in a manner similar to an accordion with a blow bellows and at least one keyboard.
Claims10
A combined electronic-pneumatic musical instrument comprising the combination of
- an electronic tone signal generator means (G), to provide electrical signals corresponding to acoustic tones whose frequency spectrum respectively determines the acoustic parameters:
- pitch, and timbre of a selected tone, or tones, for reproduction or storage by an output transducer,
- and a plurality of operator controllable electrical switch means (14, 18, 22) to selectively control the signal generator to supply output signals to the output transducer corresponding to a selected tone or tones, upon selective operation of at least one of said switch means,
- with
- operator controllable pneumatic means (10, 18, 20) coupled to at least two of said electrical switch means, conjointly operated therewith, and furnishing an air flow,
- and air flow pneumatic-electrical transducer means (26, 28, 30) responsive to said air flow and providing an electrical output signal in response to said air flow,
- said air flow transducer means being electrically connected to and additionally controlling said tone signal generator to control the envelope curve of said signals and hence the change in amplitude with time, and accordingly the volume, attack, quasi stationary behavior and decay phenomena of the signal corresponding to said selective tone, or tones provided by said signal generator means, in accordance with air flow as controlled by the operator.
