Abstract: METHOD AND APPARATUS FOR AUDIO EDITING OF MIDI FILES A method and apparatus are disclosed for the audio editing of MIDI (Musical Instrument Digital Interface) files. MIDI files make it possible to exchange information such as: musical notes, program changes, expression control and channel information between musical instruments, sequencers, computers, lighting controllers and mixers. MIDI files generally consist of serially listed channel and system messages which include at least program status messages and matching note on and note off messages. The method and apparatus of the present invention may be utilized to ensure the integrity of a source file, a copied or lifted section or a target file by automatically inserting matching note on or note off messages into a file or file section to correct inconsistencies created by such editing. Additionally, program status messages are automatically inserted into source files, copied or lifted sections, or target files to yield results which are consistent with the results which may be obtained by editing digital audio data. Timing information is selectively added or maintained such that MIDI files may be selectively edited without requiring a user to learn a complex MIDI sequencer.

Abstract: A method and apparatus are disclosed for simultaneously outputting digital audio and MIDI synthesised music utilising a single digital signal processor. The Musical Instrumert Digital Interface (MIDI) permits music to be recorded and/or synthesised utilising a data file containing multiple serially listed program status messages and matching note on and note off messages. In contrast, digital audio is generally merely compressed, utilising a suitable data compression technique, and recorded. The audio content of such a digital recording may then be restored by decompressing the recorded data and converting that data utilising a digital-to-analog convertor. The method and apparatus of the present invention selectively and alternatively couples portions of a compressed digital audio file and a MIDI file to a single digital signal processor which alternately decompresses the digital audio file and implements a MIDI synthesiser. Decompressed audio and MIDI synthesised music are then alternately coupled to two separate buffers. The contents of these buffers are then additively mixed and coupled through a digital-to-analog convertor to an audio output device to create an output having concurrent digital audio and MIDI synthesised music.

Abstract: COMPUTER-BASED, AUDIO/VISUAL CREATION AND PRESENTATION SYSTEM AND METHOD A user/PC interface system is described which enables the creation and performance of a synchronized audio/visual story on the PC. The interface enables the initial storage of a plurality of visual images. Then, it enables the creation of an audio presentation which includes labels and time indications, certain of which are employed for synchronization purposes. The system is responsive to a label to execute a predetermined command upon the appearance of the label in the audio presentation. The PC is then operated to perform the audio presentation, that performance automatically causing the display of visual images upon the occurrence of labels and time indications. An improved, table-based authoring system is also described for preparation of both the above noted audio and visual presentations. The system relies upon columnar presentations of a tabular form, each column indicating a separate control function (or comment) relating to the audio/visual presentation.
