Abstract
A display apparatus for an electronic musical instrument according to the first invention has a display section including multiple indicators provided in association with multiple tone parts, each indicator having multiple LEDs, a register section for reading out lighting time information from a memory which has lighting time information of the LEDs stored, and a counter section for performing a countdown operation in a predetermined time interval with the lighting time information in the register section as an initial value. When generation of a musical tone is instructed, the LEDs of the indicators which are associated with tone parts of the musical tone and whose quantity corresponds to volume information of the musical tone, are lit. When a count value of the counter section reaches zero, one of the LEDs is turned off or on, and the lighting time information in the register section is reset in the counter section to re-start a countdown operation. The tone levels for the individual parts are also displayed. A display apparatus for an electronic musical instrument according to the second invention has a display section including multiple indicators provided in association with multiple tone parts, each indicator having multiple LEDs. At the time of displaying the tone level, the activation/deactivation of the LEDs is controlled display in a first display mode. At the time of displaying the volume level associated with a change in volume, the activation/deactivation of the LEDs is controlled display in a second display mode.
