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. |

DETAILED DESCRIPTION In view of the foregoing, it is therefore an object of the present invention to provide an electronic musical instrument having an arpeggiator function capable of readily making up desired arpeggio patterns as one likes.
It is another object of the present invention to provide an electronic musical instrument having the arpeggiator function capable of performing arpeggio playing which is perceived as being less musically incompatible in such a manner that even if a string, which is to be essentially played for the arpeggio playing according to a predetermined arpeggio pattern, is not played, sounds are not omitted.
FIG.
1 is a principal block diagram of an electronic musical instrument having functions of the first to fourth embodiments of the electronic musical instrument according to the present invention, which will be described hereinafter.
An electronic musical instrument 10 is connected to a stringed instrument 20 in any of the first to fourth electronic musical instruments according to the present invention.
The stringed instrument 20 comprises a plurality of strings 21.
