Claim 1
Independent Claim
165 words
A rhythm generator comprising: a plurality of rhythm pattern memories to be read out in a predetermined sequence, each storing a different rhythm pattern and outputting its respective rhythm pattern in response to an addressing means; a bar counter for counting the number of bars being read out from each sequentially read out rhythm pattern memory; a first memory storing said predetermined sequence in which said plurality of rhythm pattern memories is to be read out; a second memory storing the number of bars for which each rhythm pattern memory in said sequence is to be read out; a comparator for comparing the output from the bar counter with the output from the second memory to provide a coincidence signal; and an address counter addressing said first and second memories, said address counter being responsive to the coincidence signal to increment the count value of said address counter, whereby each rhythm pattern memory in said sequence is read out for said predetermined number of bars.
