ABSTRACT:
A vibration of a string is picked up by a pickup to be converted to an electric signal. A pitch extracting circuit obtains pitch data expressing a pitch or a duration of the string vibration from the electric signal. A musical tone generating circuit generates a musical tone having a corresponding tone pitch in accordance with the pitch data. An envelope extracting circuit extracts an envelope from the eletric signal detected by the pickup and supplies a signal expressing the envelope to a multiplier. The extracted envelope signal is multiplied to the musical tone signal by a multiplier after a predetermined timing has been past. In other case, the extracted envelope signal is mixed with a synthe-envelope signal at a desired ratio, thereafter the mixed envelope signal is imparted to the musical tone signal by multiplying processing.
