An innovative composition tool that lets the user see and manipulate musical forms, exploring the relation between geometry and music. APHELIAN features a new kind of sequencer, based on a geometrical metaphor. The interface of the Standalone App is composed of 4 independent instruments. In the AUv3 extension, Aphelian behaves as a single MIDI PROCESSOR that could be used multiple times within the AU HOST to feed different audio generators. Each geometrical unit has a SHAPE that function as a TIMELINE. The user can DRAW EVENTS in the TIMELINE to create melodies. The SHAPES are located over a NOTE MAP that defines the NOTE of each EVENT. The SHAPES can be easily transformed using gestures that take full advantage of the touch screen. Any transformation in the SHAPE results in a predictable modification in the musical composition. APHELIAN offers an amazing balance between joyful exploration and accurate detail control, proposing an organic way to compose music. Inspired by Johannes Kepler’s geometrical model of the solar system, where the planets play melodies as they orbit the sun assembling a cosmic symphony. FEATURES 4 orbital sequencer engines. 1 Global Harmonic controller 4 Internal Synthesizers. 1 Internal Drum machine.
