About Amos

Amos is a multi-touch physics-driven MIDI-sending chaos machine for studio musicians and other weirdos.


In Amos’ physics-simulated room, collisions between objects trigger MIDI notes. There are five note discs, two keyboards and two walls that encourage movement. Amos sends its MIDI notes via USB, WiFi, or the Line6 MIDI Mobilizer.


Configurable Out The Wazoo

The keyboards share configurable note arrangements, octave settings and MIDI channels. Choose which notes to send, what octave to start on and how many octaves to cycle through.


Mmmm, Multi-touch

Amos supports full multi-touch control as well as being optimized for auto-running, hands-free operation. As a disc moves around, it sends a MIDI note for each collision between it and other objects in the room. When a disc strikes a keyboard key, it takes on that key’s note value and emits that value for each subsequent collision. The top and bottom walls repel the discs.

Amos Demo Video

Amos 1.2 Demo

This video shows Amos sending MIDI notes to Ableton Live and a Korg Electribe via CoreMIDI WiFi and the Line6 MIDI Mobilizer. Operation of the settings menu is shown along with the ability to specify independent MIDI channels per disc. Later in the video, disc note length settings and MIDI-out to both Live and the Korg are demonstrated.
