Abstract
An electronic musical instrument of a type having automatic performance functions includes means for switching a tone production mode to another tone production mode without stop of tone production when the automatic performance is stopped, so that a smooth continuation of a manual performance after the automatic performance is ensured. When an automatic arpeggio performance producing a tone of a percussion type envelope is stopped, the tone envelope is switched to a sustain type envelope and the tone is kept produced as long as the key for the tone is kept depressed. In an automatic bass/chord performance producing intermittent bass tones and chord tones, bass tones and chord tones are continuously produced after stopping of the automatic bass/chord performance.
