Abstract
In accordance with the musical performance by the player, a musical keyboard and an associated processor generate note command signals indicative of note pitches of the tones to be produced in response to which keys are depressed and intensity signals indicative of intensities of the tones to be produced in response to how strong the keys are depressed. A tone generator generates tone signals having pitches and intensities as determined by the note command signals and the intensity signals. A judger judges whether the intensity signals are greater than a predetermined threshold value. When the judgment is affirmative, an additive note designator generates additive note designating signals indicative of note pitches of the tones to be produced in addition to the tones produced as commanded by the depressed key, in which each additive note pitch has a harmonious relation to the corresponding key-commanded note pitch. The tone generator further generates additive tone signals having pitches designated by the additive note designating signals. An alternative detector judges whether the depressed key is a chord constituent note of the chord for the musical performance at that moment.
