Abstract
Electronic musical instrument comprises a musical tone synthesis device, a memory and pitch control device. The musical tone synthesis device processes input signals based on at least one parameter, and synthesizes and outputs musical tones with pitches in accordance with the values of the parameters. The memory stores initial values of the parameters which generate a musical tone having a target pitch. The pitch control device detects a difference between the target pitch of the musical tone and a pitch of the musical tone outputted form the musical tone synthesis device. And, the pitch control device outputs a value of the parameter which will eliminate the difference to the musical tone synthesis device.
