Abstract
An automatic performance device comprises a pattern memory for storing a plurality of performance patterns and a sequence memory for storing a pattern progression. The pattern progression is programable and is written in the sequence memory. The performance patterns are selected one by one from the pattern memory according to the pattern progression. Each selected performance pattern is read out according to a tempo pulse. An automatic performance is carried out on the basis of the read-out performance pattern.
