Abstract
In a musical tone synthesis apparatus, a sequencer provides a sequence of event data effective to command generation of musical tones. A generator operates according to the event data to generate the musical tones. A detector detects when either of the sequencer and the generator suffers from misoperation which would cause abnormal generation of the musical tone. A blocking device operates when the misoperation is detected for blocking the generator to prevent the abnormal generation of the musical tone.
