    You can now specify shuffle settings for each album.

    Some albums, such as best-of albums, have no connection between songs, and in the case of multiple discs combined into one album, you may want to listen to each disc separately.

    A version that supports such detailed settings has been revived.

    When using in conjunction with PlayingAlbums for iOS, both must be version 3.1 or higher.

    The application does not include any songs or other content. You must first create a playlist by importing from a CD or using a subscription service like Apple Music.

    Thank you for your waiting. PlayingAlbums will be updated. It will improve accuracy in synchronizing playlists and the next song to be played between owned devices. It will implement a mode of playing within the application without using the system standard music (information is not shared with the system), which was requested by users. It has new interfaces.

    Sorry. The macOS and iPad versions, which allow for album-specific settings, are currently under development and cannot be updated at this time. Information set in previous versions will continue to be available as long as the data has not been deleted, for example by using iCloud. Please wait.

    ScatterMaker - Create Scatter Plots

    What's new? September 23, 2020

    I apologize a problem that graphs cannot be exported correctly depending on the version of macOS. This bug has been fixed in this version.

    Have you ever struggle to create beautiful scatter plots?

    When you need to check distribution of your data, scatter plots may be suitable. However, it is really difficult to create a beautiful scatter plot using Microsoft Excel, or other popular applications for graphs at a reasonable price.

    Here is a simple application for scatter plots.

    • What's new? September 23, 2020

      Fixed a bug that graphs cannot be exported correctly depending on the version of macOS.
