Audio signal outputting method, audio signal reproduction method, and computer program product

An audio signal outputting method comprising the steps of:

• capturing the musical piece progress timing for each MIDI message of multiple channels, mutually synchronized musically;
• detecting the occurrence of an event which changes the audio signal to be reproduced and outputted;
• and
• upon detection of said event occurrence, reproducing and outputting an audio signal by selecting from said plurality of MIDI messages a combination of MIDI messages corresponding to said event, at a timing where there is a musical break.

A computer program product in which a program for causing a computer system to execute game processing is recorded on a computer-readable recording medium, wherein said computer program causes execution of the steps of:

• capturing the musical piece progress timing for each of a plurality of data streams, mutually synchronized musically;
• detecting the occurrence of an event which changes the audio signal to be reproduced and outputted;
• and
• upon detection of said event occurrence, reproducing and outputting an audio signal by selecting from said plurality of data streams a combination of data streams corresponding to said event, at a timing where there is a musical break.

An audio signal outputting apparatus comprising:

• means for capturing the musical piece progress timing of each of a plurality of data streams, mutually synchronized musically;
• means for detecting the occurrence of an event which changes the audio signal to be reproduced and outputted;
• and
• means for reproducing and outputting an acoustic signal by selecting from said plurality of data streams a combination of data streams corresponding to said event upon detection of said event occurrence, at a timing where there is a musical break.
