APHELIAN features a new kind of sequencer, based on a geometrical metaphor. The interface is composed of 4 independent instruments, distributed in the corners. Each instrument 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.

4 orbital sequencer engines.
1 Global Harmonic controller
4 Internal Synthesizers.
1 Internal Drum machine.

SUPPORTS: Inter App Audio, Ableton Link Sync, MIDI OUT per channel (Note on/off and Control Change), Audiobus and Audiobus State

Great composition tool

You can get something up and running in this app in a few minutes, and overall it’s a very intuitive process to create a great sounding piece of music.

I’m sure this will appeal to people with little musical knowledge as much as it will appeal to anyone with a good grasp of music theory. I’m loving both the ease of composition as much as I am looking forward to making more complex music.

Well done guys - original approaches to making music on mobile devices are becoming more rare, but this app combines flexibility, depth and inspiration in equal amounts.

Been using it in live performances

Full props to this app.
Is there any chance there will be a user forum where we can share our projects and download projects from?

Solid Reboot

The first update to the app has fixed many of the bugs, crashes, and freezes. The developer continues to work on the remaining issues.

The app is now very functional and the MIDI out and built-in synths are great to use especially combined with the scene and song modes.

Looking forward to a manual so I can better understand and use the app’s deep feature set in my compositions.
