An automatic performance apparatus for sequentially reading out performance data sequentially stored in a performance data memory to execute automatic performance, detects depression of a step forward key, and generates a tone for a predetermined time T3 on the basis of performance data in the performance data memory designated by an address pointer. When the step forward key is depressed again within the predetermined Time T3 from its first depression, the same performance data tone is continuously generated for the predetermined time T3 from the second depression timing of the step forward key. When the step forward key is continuously depressed for a predetermined time T2 or more from its first depression timing, the address pointer is stepped up upon each predetermined time T1 to generate a performance data tone sequentially designated by the address pointer. According to this automatic performance apparatus, automatic performance data can be rapidly edited by simple manipulation.
