Patent ID: 7432437

Claim:
An arpeggio playing apparatus comprising: an arpeggio pattern storing device that stores at least one arpeggio pattern pair including a regular version pattern and an accentuated version pattern for automatic arpeggio performances; a performance data input device for inputting performance data that represent note numbers and key-on velocities indicative of a user's manual performance for designating automatic arpeggio playing by the apparatus; a velocity detecting device that detects the key-on velocities; an arpeggio pattern readout device that reads out, from the arpeggio pattern storing device, the regular version pattern when the detected velocity is less than a predetermined threshold value, and the accentuated version pattern when the detected velocity is not less than the predetermined threshold value; and an arpeggio tone processing device that processes data for automatically playing arpeggio based on the inputted performance data and according to the arpeggio patterns of the read-out versions.
