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.
Claims7
A musical tone synthesis apparatus having a processor, said apparatus comprising:
- a sequencer that provides a sequence of event data effective to command generation of a musical tone signal, said sequencer comprising a first software module including a first program executable by said processor;
- a generator that is connected to the sequencer and generates the musical tone signal according to the event data, said generator comprising a second software module including a second program executable by said processor, said second program entering a misoperation condition when said program is unintentionally hung up;
- a detector that is connected to the generator, and that detects said misoperation condition which would cause abnormal generation of the musical tone signal;
- and
- a blocking device that is connected to the detector and blocks the generator to prevent the abnormal generation of the musical tone signal when the misoperation condition is detected.
A musical tone synthesis apparatus comprising:
- sequencer means operative to provide a sequence of event data effective to command generation of a musical tone signal;
- generator means operative according to the event data to generate the musical tone signal;
- detector means for detecting a misoperation condition of the generator means which would cause abnormal generation of the musical tone signal;
- and
- blocking means operative when the misoperation condition is detected for blocking the generator means to prevent the abnormal generation of the musical tone signal.
A musical tone synthesis method comprising the steps of:
- operating a sequencer device to provide a sequence of event data effective to command generation of a musical tone signal;
- operating a generator device according to the event data to generate the musical tone signal;
- detecting when a misoperation condition of the generator device occurs which would cause abnormal generation of the musical tone signal;
- and
- blocking the generator device to prevent the abnormal generation of the musical tone signal when the misoperation condition is detected.
A machine readable media containing instructions for causing a musical tone synthesis apparatus to perform a method comprising the steps of:
- operating a sequencer device to provide a sequence of event data effective to command generation of a musical tone signal;
- operating a generator device according to the event data to generate the musical tone signal;
- detecting when a misoperation condition occurs which would cause abnormal generation of the musical tone signal;
- and
- blocking the generator device to prevent the abnormal generation of the musical tone signal when the misoperation condition is detected.
