CodeFN42 has announced the release of Cales, a free MIDI utility plug-in for Windows.

CodeFN42 Cales

Cales is a VST plugin that allows you to map your keyboard’s keys to a musical scale. This will ensure that you will always stay in key, and never hit a wrong note.

When “easy mode” is enabled, you can play any scale using only the white keys with “C” always being the tonic (or “root” note).

More than 20 scales are included, and you can easily add your own custom scales.

The plug-in is a free download for Windows (VST).
