Abstract
In an electronic musical apparatus having a generator for generating a tone, a play member is provided for playing a music such that a key-on touch operation and a key-off touch operation are performed on the play member to input a note of the music. A detector detects the key-on touch operation and the key-off touch operation to generate key-on information and key-off information. A controller operates based on the key-on information and the key-off information for controlling the generator to generate a tone corresponding to the note. The detector detects a transitional state of the key-off touch operation for generating a sequence of first key-off information and second key-off information indicative of the transitional state of the key-off touch operation. The controller responds to the first key-off information for controlling the generator to start generating of a trailing tone of the note and responds to the second key-off information for controlling the generator to stop generating of the trailing tone of the note. The controller responds to the key-on information for controlling the generator to generate a leading tone of the note, which is then changed to a trailing tone of the same note in response to the first key-off information.
