Abstract
An electronic musical instrument is provided with a dedicated internal tone generator circuit and a removable external tone generator. When music performance information (e.g., MIDI data) of a plurality of tracks recorded on an external recording medium is to be introduced for reproduction by the musical instrument, one or more tracks capable of or suitable for reproduction by the electronic musical instrument are selected in accordance with a predetermined condition. The internal tone generator circuit generates a tone on the basis of the performance information of the selected tracks. The performance information of the other tracks that are not selected in the electronic musical instrument is sent to the external tone generator for audible reproduction thereby.
