Abstract
An electronic keyboard instrument includes: a keyboard including a plurality of keys; a plurality of switches that are provided for each key and include a first switch and a second switch that are sequentially turned on by pressing of the key; and a processor. The processor instructs that a noise sound corresponding to a selected musical instrument sound be produced in accordance with a prescribed first envelope upon detecting turning on of the first switch by pressing of the key, and instructs that a main musical sound corresponding to the selected musical instrument sound be produced after detecting turning on of the second switch.
Claims13
An electronic keyboard instrument comprising:
- a keyboard including a plurality of keys;
- a plurality of switches for each of the plurality of keys, the plurality of switches in each of the plurality of keys including a first switch and a second switch that are sequentially turned on in the order of the first switch first and the second switch thereafter when the key is pressed;
- and
- a processor;
- wherein the processor:
- causes a noise sound corresponding to a musical instrument sound to be produced in accordance with a prescribed first envelope that determines volume changes over time, upon detecting turning on of the first switch by pressing of the key;
- and
- causes a main musical sound corresponding to said musical instrument sound to be produced after detecting turning on of the second switch.
A method performed by a processor in an electronic keyboard instrument that includes, in addition to the processor:
- a keyboard including a plurality of keys;
- and a plurality of switches provided for each of the plurality of keys, the plurality of switches in each of the plurality of keys including a first switch and a second switch that are sequentially turned on in the order of the first switch first and the second switch thereafter when the key is pressed, the method comprising, via the processor:
- causing a noise sound corresponding to a musical instrument sound to be produced in accordance with a prescribed first envelope that determines volume changes over time, upon detecting turning on of the first switch by pressing of the key;
- and
- causing a main musical sound corresponding to said musical instrument sound to be produced after detecting turning on of the second switch.
A non-transitory computer-readable storage medium having stored thereon an program executable by a processor in an electronic keyboard instrument that includes, in addition to the processor:
- a keyboard including a plurality of keys;
- and a plurality of switches provided for each of the plurality of keys, the plurality of switches in each of the plurality of keys including a first switch and a second switch that are sequentially turned on in the order of the first switch first and the second switch thereafter when the key is pressed, the program causing the processor to perform the following:
- causing a noise sound corresponding to a musical instrument sound to be produced in accordance with a prescribed first envelope that determines volume changes over time, upon detecting turning on of the first switch by pressing of the key;
- and
- causing a main musical sound corresponding to said musical instrument sound to be produced after detecting turning on of the second switch.
