Abstract
An electronic musical instrument includes an ROM which stores tone color parameters for determining musical tone characteristics of musical tone signals. Operating elements are operated to create operation information for controlling the musical tone characteristics on real time basis. A tone generator circuit generates the musical tone signals, based on the cone color parameters read from the ROM and the operation information created by the operating elements. Scene memories and a RAM store the operation information created by the operating elements. The operation information is read from the scene memories or the RAM, in response to an instruction from the operator. The operation formation thus read is supplied to the tone generator circuit.
