Enharmonic OmniScriptum Enharmonic keyboard

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An enharmonic keyboard is a musical keyboard based on an enharmonic scale. At the very least such keyboards will have 17 keys per octave, and enharmonically equivalent notes will have different pitches. A typical keyboard will have one key for, for instance, C sharp and D flat, but a basic 17 key enharmonic keyboard will have two different keys for these notes. Traditionally, these keyboards use split sharps to express both notes.
