Abstract:
1. An electronic keyboard instrument operative with reference to a threshold velocity for generating a musical sound signal, comprising: a key that moves from an initial position to a full stroke position via first, second, and third positions sequentially when the key is depressed; a velocity detector that detects a first key velocity of the key when the key moves from the first position to the second position, and detects a second key velocity of the key when the key further moves from the second position to the third position; a predictor that obtains a predicted key-on time and a predicted key velocity based on the first key velocity, provided that the first key velocity is equal to or greater than the threshold velocity which is predetermined for control of generating of the musical sound signal; a first generator that generates the musical sound signal based on the first key velocity and the second key velocity if the first key velocity is equal to or greater than the threshold velocity and the second key velocity is detected before the predicted key-on time; and a second generator that generates the musical sound signal based on the first key velocity and the predicted key velocity if the first key velocity is equal to or greater than the threshold velocity and the second key velocity is not detected before the predicted key-on time.
