Abstract
PURPOSE: To surely prevent input errors of pitch information by letting input sound be immediately produced at the time of inputting the pitch information through keyboard operation into the musical instrument built-in with a memory device.
CONSTITUTION: When the key switches Sn-1, Sn-2 of two circuits which are mutually cooperatively closed for each key are closed by operating the (n)th key, the pitch information is sent from the switch Sn-1 to an encoder 2, whereby it is coded a and is then applied to a memory 3. The signal from the switch Sn-2 is applied to an oscillator 4, and therefore if the oscillator 4 is constituted by divider chain or voltage control type and is oscillated at the frequency corresponding to the switch Sn-2, an output appears from the oscillator 4 each time when one pitch information is inputted by operating a keyboard 1. This output is sounded through an amplifier 5 and a speaker 6. Since this lets the pitch information be immediately confirmed, its input error may be surely prevented.
