A tone generation control device sets a setting value for crosstalk cancellation. When vibration generated in a target striking surface is detected, a value indicative of the degree of crosstalk that the target received from comparison striking surfaces is calculated. The calculated value is displayed regardless of whether a tone generation instruction has been output. Meanwhile, setting values used for crosstalk cancellation for the respective striking surfaces are also displayed. Therefore, the user can observe and understand as to whether the vibration generated at the target is vibration caused by crosstalk received from the comparison striking surface, such that setting values to be used for crosstalk cancellation can be suitably set.
