HexaChrom turns your iPad into a musical performance controller, enabling you to wirelessly play your OSC or MIDI electronic musical instruments – virtual instruments running on a laptop/desktop computer, or any hardware instruments attached to your laptop/desktop computer.
HexaChrom takes an alternative approach to the majority of MIDI keyboard controllers in that it uses an isometric note layout, where the notes are presented as a hexagonal matrix of keys. There are many such isometric layouts, though HexaChrom uses the Harmonic Table layout, which is a modern variation of the Tonnetz (tone network), devised by the famous mathematician Euler.
This note layout has particularly useful musical intervals between adjacent keys, ie along the 3 major axes : minor thirds, major thirds and perfect fifths. In the Western musical tradition, the intervals of the major and minor thirds dominate chordal structures. Consequently, this layout offers a number of advantages over the more conventional clavier-style keyboards : consistent chord shapes irrespective of key, the ability to span several octaves with one hand and to play basic major or minor triads with a single finger. Together resulting in an easier learning curve.
It also encourages the user to approach music differently, just as the different note layouts of pianos and guitars engender different playing styles.
HexaChrom sends MIDI data via the OSC protocol, using OSC’s “M” data type. To control MIDI devices (hardware or software) you will need to run an application on a laptop/desktop computer to translate the OSC messages into MIDI messages. For Mac users, OSCulator is the preferred solution.
