Abstract
An instrument for recording and playing musical playing data comprises a pattern memory, a timing designation key for designating playing back timing of the pattern data, a sequence track for recording sequence data, and a writing device for writing the pattern data into the sequence track at the playing back timing designated with the timing designation key. The pattern data is read from the pattern memory and transferred to the place, in the sequence track, corresponding to the designated timing. The transferred note data is modified with the designated chord. The instrument further comprises a backing track storing backing data, any part of which can be also transferred to the sequence track.
