Abstract
In addition to a general transposition setting device for setting a transposition for an entire musical instrument, there is provide an automatic-performance transposition setting device for optionally setting a transposition value for automatic performance. Automatic performance data is transposed in accordance with the transposition value set by the automatic-performance transposition setting device and a visual performance guide display based on the transposed automatic performance data is provided via a key display as an automatic performance process is advanced on a desired music piece. Human player depresses keys in accordance with the visual performance guide display so that tones corresponding to the depressed keys are generated. The transposition set via the automatic-performance transposition setting device does not act on the tones manually performed by the player's key depression operation, and only the transposition set via the general transposition setting device becomes effective on such manually-performed tones.
