    Abstract: HIGH SPEED TAB RACK In a high speed trail printer an improved electronic tab rack is provided. A method and apparatus are disclosed for decreasing the time required to determine the location of the next tab involving accessing a condensed tab rack. The condensed tab rack is set up when the tabs are entered and contains for each byte of the basic tab rack one bit indicating whether or not the associated tab rack byte specifies at least one tab stop position.

    Abstract: MIDI FILE TRANSLATION OF TEE DISCLOSURE A system and method for translating MIDI files is used with a sequencer and synthesizer. When a MIDI file is imported into a system, the file is scanned and voice assignment information extracted. This information is stored in a converted file. If desired, the extracted information can be stored using MIDI system exclusives. This allows either any original program change information, or the extracted information, to be used during a performance of the converted MIDI file.

    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: AT9-?1-001 WORD PROCESSING SYSTEM HAVING A FORMATTING BIDIRECTIONAL PRINTER A word processing system is provided having a bidirectional printer with formatting capability. The system includes a word processor having means for outputting a stream of sequential data readable in only one direction. The data comprises blocks of character data representative of the characters to be printed interspersed with blocks of control data representative of the format in which the characters are to be printed; each block of control data has an immediately preceding control block identifier. The bidirectional printer includes means for receiving the stream of sequential data, means for scanning the stream of data and means for inserting a control block identifier at the end of each control block which identifier corresponds to the identifier preceding the control block, whereby the stream of sequential data is made readable in both the forward and reverse directions within the printer.
