The music score display screen changes depending on the size of the window. When the window size changes, the display position of the music score is automatically adjusted.

Score Viewer has two types of display methods, "Minimum display" and "Vertically aligned".

"Minimum display" mode makes the height of the music score variable to reduce the margin. This allows you to view the score in less space.

"Vertically aligned" mode aligns the music score vertically. This will make each part of the music score display at the same height. This function can be used for music score data whose format is v3.1 or later.

You can switch between these two modes on the Common Score Setting.

The following icons are displayed on the music score display screen.

The Auto Scroll is a function that automatically scrolls the music score in sync with the MP3/AAC playback. Before using this function, you need to adjust the start position of the song.

There are several ways to VBR MP3/AAC files to CBR. I recommend the free software Audacity.

This software calculates the timing to scroll the music score based on the "start position" specified on the Calibration screen.

The calibration procedure is shown below.

A simple metronome makes it easy to adjust timing.

If you click the rehearsal mark panel, the music score will move to the specified rehearsal mark. However, it cannot be clicked during MP3/AAC playback.

If you click the configuration icon on the menu, the configuration screen opens.

In the music score setting screen, you can set the music score display for each part. If the music score has a large number of parts, you can make the music score easier to see by hiding unnecessary parts.

The above figure was an example of hiding the 6-part music score in order. You can hide not only the staff notation but also chords, rehearsal marks, lyrics, and TAB units.

The meta information of the currently displayed music score is displayed on the Music Property screen.

The current version cannot change the shortcut key setting.

On the MP3/AAC player setting screen, you can change various settings for MP3 player control.

On the menu display setting screen, you can select the control to be displayed in the menu.

On the common score setting screen, you can set the music score display method and margin. If you turn on the check box at the top, the music score will be displayed in "Vertically aligned" mode. For details, refer to 5-3. Alignment.

You can set different margins for each of the two modes.

On the Common Settings screen, you can change the scroll speed and language settings. The contents set here are saved in the cookie, and the set values will be valid from the next time onward.

At the first startup, the language setting will change automatically depending on the browser language. The current version is set to "Japanese" for Japanese browsers, and "English" otherwise. However, even if you set the language to "English", Japanese lyrics will not be displayed in English.

This tool can specify the following parameters in the query string (URL argument).

This software recommends using Google Chrome.
