Abstract
A keyboard unit includes: a key; a plurality of members which include the key, and each of which has an engaged section for forming an engaged state, the engaged state changed by turning of the key, at least a portion of the engaged section formed of a conductor; a detector which is configured to detect information on the engaged state of the plurality of members by detecting a conduction state between the at least portions of the engaged sections which are in contact with each other; and a determiner which is configured to determine a musical sound parameter based on a detection result of the detector.
Claims20
A keyboard unit including a key, a plurality of component members and a hammer, as members in which an engaged state of members to be engaged with each other is changeable in pressing/releasing strokes of the key, the hammer driven by a pressing operation of the key, and the hammer not operating in synchronization with the key in the pressing/releasing strokes of the key in some cases, the keyboard unit comprising:
- a first detector, provided for a first set including:
- a movable member;
- and a corresponding member to be engageable with the movable member, which are selected from among the key, the plurality of component members and the hammer, and configured to detect an engaged state of the movable member and the corresponding member in the first set;
- a second detector, provided for a second set different from the first set and including:
- a movable member;
- and a corresponding member to be engageable with the movable member, which are selected from among the key, the plurality of component members and the hammer, and configured to detect an engaged state of the movable member and the corresponding member in the second set;
- and
- a determiner configured to determine a musical sound parameter for musical sound control based on a detection result of the first detector and a detection result of the second detector, wherein
- when engaged sections of the movable member and the corresponding member in the set corresponding to at least one of the first and second detectors are in contact with and are engaged with each other, the engaged sections become electrically conductive, and the at least one of the first and second detectors detects an engaged state of the movable member and the corresponding member depending on a state of electrical conduction between the engaged sections.
A keyboard unit comprising:
- a key;
- a plurality of members which include the key, and each of which has an engaged section for forming an engaged state, the engaged state changed by turning of the key, at least a portion of the engaged section formed of a conductor;
- a detector which is configured to detect information on the engaged state of the plurality of members by detecting a conduction state between the at least portions of the engaged sections which are in contact with each other;
- and
- a determiner which is configured to determine a musical sound parameter based on a detection result of the detector.
