Electronic musical instrument having sound image localization circuit

An electronic musical instrument, which incorporates at least two tone signal output means, and which controls sound image localization of the musical sounds of the instrument in accordance with localization data by changing the levels of at least first and second tone signals that are provided, respectively, to said tone signal output means, said instrument comprising:

• tone signal generation means for generating a tone signal;
• output control data production means receiving the localization data and providing tone signal volume data and a selection signal;
• and
• tone signal output level control means receiving said generated tone signal and providing said first and second tone signals to said tone signal output means, said tone signal output level control means having means for altering the generated tone signal responsive to said volume data to provide one of said first and second tone signals, said tone signal output level control means providing a signal corresponding of the tone signal generated by said tone signal generation means as the other of said first and second tone signals, said tone signal output level control means having selection means responsive to said selection signal for providing one of said first and second tone signals to one of the tone signal output means, and for providing the other of said first and second tone signals to the other of the tone signal output means, thereby to control sound image localization of the musical sounds of the electronic musical instrument.
