Tablature Maker

Tablature Maker is a Java-based program designed to help you build custom new tablatures for the FR-18 accordion.

Intuitive layout

The app is based on two layouts: the home screen where the users can establish the tablature set, name, and key, together with opening or exporting tablature configurations from/to RDKC formats, while the second panel is the tablature itself which is automatically generated based on the key users select.

Limited features

Except configuring the bass and treble keyboards that must be based on a selected key, there aren't any other features Tablature Maker really has. Of course, users can set multiple configurations of the same layout and have them saved to a basic XML file, but that's about it.
However, on a basic level this can be useful. The exported files contain all the numerical tablature layouts in a comprehensive order so it can be easily opened in any text reader. Unfortunately, users won't be able to save the XML file with other names except RDKC 1 to 10.
Tablature sets can also be changed since the program offers 12 default layouts which can be tweaked by users. However, they are mostly identical in layout, with only the keys being different.
Musicians can reset the keys of a tablature too, but they will have to re-assign both the opening and the closing notes, together with their afferent chords.

Conclusion

Tablature Maker is a decent program that allows users to mathematically set accordion notes using an emulated instrument layout. Setting the key is also important in order to allow the desired key combinations. Users can also change twelve available layout templates and have each of them saved to XML file formats.
Therefore, this app is dedicated to accordion musicians who can predefine their keys without having to test them out on their own expensive instruments.
