Abstract

PURPOSE: To switch plural musics continuously accurately, by providing a means which switches program sources when the phase of the current pulse train and the phase of the pulse train to be selected next coincide with each other on a basis of signals from generators for pulse trains corresponding to fundamental pulses of music of plural program sources.
CONSTITUTION: Music signals input to input terminals 11 and 12 are transferred to not only switching circuit 16 but also pulse generators 13 and 14 to generate pulse trains corresponding to respective fundamental pulses. These output pulses are sent to coincidence signal generator 15; and when respective pulse trains coincide with each other in phase, the coincidence signal is output. This output is transferred to switching circuit 16 immediately to able to not only switch program sources but also select an opportunity for switching by control device 19. The next music may be faded in simultaneously with fading-out of the preceding music to prevent shock tone. As a result, plural musics are switched continuously accurately.
