Abstract
The present disclosure relates to a method and system for calibrating a musical device. In some embodiments, a method for calibrating a musical device includes: energizing an actuator to actuate a key using a force corresponding to a first intensity level; obtaining, from a sensor, a first sensor signal representing motion information of the key corresponding to application of the force; and calibrating the musical device based on the first sensor signal.
Claims18
A system, comprising:
- a storage device storing instructions;
- and
- at least one processor configured to communicate with the storage device, the at least one processor, when executing the instructions, being configured to cause the system to perform operations including:
- obtaining a sensor signal representative of motions of a key;
- determining whether a first value of the sensor signal exceeds a first reference value corresponding to a first position of the key, wherein the first value of the sensor signal is obtained at a first time instant and the first position is located between a top position and an end position of the key;
- and
- generating a first indication that the key has reached the first position in response to determining that the first value of the sensor signal is greater than the first reference value, wherein the processor is further configured to cause the system to perform the operations including:
- obtaining a second value of the sensor signal at a second time instant;
- determining whether the second value of the sensor signal exceeds a value of a second reference value corresponding to the end position of the key;
- and
- generate a second indication that the key has reached the end position in response to determining that the second value of the sensor signal is greater than the second reference value.
A method, implemented on a computing device having at least one processor, at least one computer-readable storage medium, the method comprising:
- obtaining a sensor signal representative of motions of a key;
- determining whether a first value of the sensor signal exceeds a first reference value corresponding to a first position of the key, wherein the first value of the sensor signal is obtained at a first time instant and the first position is located between a top position and an end position of the key;
- generating a first indication that the key has reached the first position in response to determining that the first value of the sensor signal is greater than the first reference value,
- obtaining a second value of the sensor signal at a second time instant;
- determining whether the second value of the sensor signal exceeds a value of a second reference value corresponding to the end position of the key;
- and
- generating a second indication that the key has reached the end position in response to determining that the second value of the sensor signal is greater than the second reference value.
A non-transitory computer readable medium comprising executable instructions that, when executed by at least one processor, cause the at least one processor to effectuate a method comprising:
- obtaining a sensor signal representative of motions of a key;
- determining whether a first value of the sensor signal exceeds a first reference value corresponding to a first position of the key, wherein the first value of the sensor signal is obtained at a first time instant and the first position is located between a top position and an end position of the key;
- generating a first indication that the key has reached the first position in response to determining that the first value of the sensor signal is greater than the first reference value,
- obtaining a second value of the sensor signal at a second time instant;
- determining whether the second value of the sensor signal exceeds a value of a second reference value corresponding to the end position of the key;
- and
- generating a second indication that the key has reached the end position in response to determining that the second value of the sensor signal is greater than the second reference value.
