5th February 2015
CodeFN42 has released Cales, a free VST MIDI plugin for Windows that allows a user to map a keyboard's keys to a musical scale. This will ensure that the user will always stay in key, and never hit a wrong note.
When "easy mode" is enabled, a user can play any scale using only the white keys with "C" always being the tonic (or "root" note).
More than 20 scales are included, it is designed to allow a user to easily add their own custom scales.
Price: Free.
