Abstract
An electronic keyboard apparatus capable of changing, with a simple construction, a musical tone control characteristic for each pedal manipulation stroke section. A detection value representing a pedal depression depth is converted into an output value according to a table group, and a musical tone parameter is controlled based on the output value. The table group includes default and alternate tables exhibiting a hysteresis such that the output value converted from the same detection value becomes smaller in a reverse pedal stroke than in a forward pedal stoke. In the forward stroke, the default table is changed to the alternate table when the detection value passes a second threshold value provided on a deeper depression depth side than a first threshold value. In the reverse stroke, the alternate table is changed to the default table when the detection value passes the first threshold value.
