Abstract
Tone lever switches deliver respective digital information signals each representing the manipulated state of each tone lever. A memory circuit memorizes plural sets of the information signals. A write/read control circuit determines whether the memory circuit memorizes the digital information signals from the tone lever switches or it delivers out the memorized digital information signals. A tone color control circuit controls the respective intensities of the tone signals of respective voices in accordance with the information signals read out from the memory circuit.
