Abstract
PURPOSE: An automatic player which is provided with a control means advancing letting the address assignment of a melody information memory means advance at a speed faster than that at the sound outputting based on the operation of a fast feed key.
CONSTITUTION: When a flip-flop F1 is set by the operation of a fast feed key QF, an OR gate OG 2 goes ON, causing the signal So to generate. In this state, the read- out speed from a program memory VM is low. At this same instant, a gate G4 is also turned ON by setting of F1. The CHL signal from a decoder KD is the signal outputted when the signal having been read out through an output control circuit OC from the memory VM was note information. Since the gate G4 is held turned ON by this, a count-up circuit CU is operated immediately when the CHL signal is outputted, whereby the contents of the counter AR are counted up by 1. The operation of the key QF causes the address counter AR to be kept counted up at a low speed and the contents thereof are displayed as decimal number in a display body DSP by a display driving circuit D.
