PURPOSE:To display the start of singing, tempo, etc. with a simple constitution by providing the titled device with a memory storing data set up in responding to an input signal and forming a display signal a prescribed timing by a starting signal. CONSTITUTION:A memory 2 in which data, etc. are stored is connected to a CPU1 and a clock signal from a clock oscillator 3 is divided into a required frequency by a frequency dividing circuit 4. A starting signal from an input terminal 7 is supplied to a port 6 to conduct gate circuits 5, 8, 12. A signal from the circuit 4 is supplied to a singing starting time processing circuit 9. A preset value and frequency dividing ratio which are read out from the memory 2 are supplied to the circuit 9 through an output port 10 and the counted value is outputted to a terminal 11 to display the start of singing on a display part. The signal from the circuit 4 is also supplied to a tempo processing circuit 13 through the circuit 12 and the frequency dividing ratio read out from the memory 2 is supplied to the circuit 13. The output of the circuit 13 is displayed on the display part as a tempo through a terminal 14. |
