ABSTRACT:
Even though a control apparatus adapted for controlling a sound source of a keyboard type musical instrument is used with any type of electronic instruments connected therewith as a performance input apparatus, the control apparatus can provide after-touch effect as a user expects. Especially when a wind instrument playing mode is selected the control apparatus generates control data in a state inherent to a wind instrument playing mode on the basis of the received after-touch data to control musical tones, and suppresses amplitudes of variations of the control data when the after-touch data vary within a low amplitude range. Further, when the control apparatus has received a plurality of after-touch data, the control apparatus obtains only one of after-touch data, which is to be processed, thereby applying after-touch effect to musical tones with no time delay after a player's playing operation.
