ELECTRONIC MUSICAL INSTRUMENT PROVIDED WITH DEVICES FOR INDICATING PRESET STATE OF RESPECTIVE VOICES

摘要

An electronic musical instrument having a plurality of tone volume setters for presetting the amplitude levels of musical tone signals of respective tone color voices comprises a plurality of variable resistors gang-operated with the tone volume setters and connected to a power source so as to deliver such levels of voltage as represent the preset states of the tone volume setters; and indicators respectively connected to the variable resistors and indicating the respective preset states. The brightness of the indicator is made to represent the amplitude level of the respective tone color voices preset by the tone volume setter.
