ABSTRACT:
An electronic musical instrument includes a first tone generator for generating a musical tone in response to each depression of key on an accompaniment keyboard and a second tone generator for generating a musical tone in accordance with the musical performance data read from the memory. In a specific mode, the player can cause the first tone generator to generate a musical tone through the accompaniment keyboard with the accompaniment being automatically played. In a mode for recording an accompaniment of a music into the memory in a step manner, a chord is detected from keys depressed on the accompaniment keyboard, and data representative of the detected chord is written into the memory together with data representative of a note-length designated by note-length selection switches. In a mode for recording an accompaniment in real time, each time keys are depressed, the chord data of the depressed keys is written into the memory together with the contents of a tempo clock counter. States of various control elements of a control panel for controlling the generation of the musical tone can also be stored into the memory. The control elements are automatically set to the stored states when the accompaniment is automatically played. If desired, only the control elements can be automatically set to the stored states so that the player can play an accompaniment without operating the control elements.
