Abstract
A performance data generation apparatus generates performance data for controlling the tone generation condition of a tone to be generated based on a string vibration signal obtained from the string vibration of a stringed instrument. The performance data generation apparatus includes an operation member for selecting a predetermined performance operation mode and a control device responsive to the operation member. When the predetermined performance operation mode is selected by operating the operation member, the control device does not output note-on data or note-off data among performance data that is generated based on the string vibration signal, and outputs specified performance data other than the note-on data and the note-off data.
