  • Patent number: 7514622
    Abstract: A control unit controls to access the beat guide file for timings of beats, cues, lyrics, and messages of musical sound data to be reproduced, and controls an image processing unit to display beat guide objects (52a and 52b), which respectively represent beat timings and reproducing pitches of selected musical sound data. This allows a user to reproduce musical sound data at will by referring to the beat guide objects (52a and 52b) and visually recognizing beat progression, reproducing pitches, cue positions, lyrics, and messages of the musical sound data to be reproduced.

  • Patent number: 5247455
    Abstract: A method of verifying wiring layouts including the steps of preparing a first reference value representing the minimum required distance between each combination of two arbitrary kinds of wiring elements; preparing a second reference value representing the minimum required distance between the two straight wirings in a prescribed positional relation (parallel to each other, for instance); extracting two arbitrary wiring elements from the layout data; determining the combination of the kinds of the two wiring elements extracted; determining whether the two straight wirings are in a predetermined positional relation if the two wiring elements are both determined to be straight wirings; determining whether a predetermined relation is established between the first or the second reference value and the distance between the extracted wiring elements by comparing the distance between the extracted two wiring elements with the first reference value if the two wiring elements are determined to be straight wirings in a
