ABSTRACT:
An automatic performance apparatus with the concert magic function includes a memory for storing automatic performance data composed of a sequence of note data. Each note data includes a data of gate time and a data of step time. When it is detected that at least one of the keys corresponding to the sequence of note data is pushed, a current note data of the sequence is read out from the memory. Then, there are executed a sound generation stopping process for a previous note data and a sound generating process for the current note data. When it is detected that all of keys corresponding to the sequence of note data are released, a sound generation stopping instruction is issued and the sound generation for the current note data is stopped in the response to the sound generation stopping instruction. The sound generating process and the sound generation stopping process are executed using a reference time period which is determined based on a tempo. The tempo can be changed on the way of performance of a music.
