Abstract: An electronic musical instrument for conducting an arpeggio performance of a stringed instrument capable of readily producing a pattern for the arpeggio performance as one likes, and also of conducting the arpeggio performance which is perceived as being less musically incompatible even if the player makes a mistake during a performance of allocating of pitch at the time of the arpeggio performance. A pattern for the arpeggio performance is produced adopting such a rule that a time axis is renewed when all the strings become silent, or such a rule that it is regarded as having the same timing while a pedal is kept depressed. When the arpeggio performance is conducted, even if a mismatch occurs between the string of the pattern and the string played for a pitch allocation, those strings are compulsively allocated together.

Abstract: An automatic performance, such as an automatic arpeggio performance or a short-phrase sequence performance, is executed on the the basis of manual performance note data corresponding to key depression on a keyboard, and automatic performance note data are obtained from the automatic performance. The manual performance note data and automatic performance note data are output to an external device after both of the note data are imparted different MIDI channel messages, i.e., channel identification data. The manual performance note data and automatic performance note data can be used properly because they can be accurately distinguished from each other by the different channel identification data. For example, it is possible to avoid the inconvenience that a further automatic performance is executed on the basis of the automatic performance note data.

Abstract: An electronic musical instrument generates musical tones corresponding to a melody tone and a chord tone which are designated by a performer. In order to apply a specific musical effect or generate an ornament, a front percussive tone, or forefall, is automatically added to the melody tone, wherein this front percussive tone has the predetermined pitch difference with respect to the melody tone. This front percussive tone is additionally generated prior to the melody tone in the predetermined short period. Instead of this front percussive tone, it is possible to generate an additional tone which has the same tone name as any one of constituent tones within the chord tone but its tone pitch is different from that of the melody tone. When generating plural melody tones and plural additional tones, these tones are sequentially generated by a predetermined time difference in a pitch descending or ascending order.
