Amos is a reactive MIDI instrument. It sends MIDI notes to your software synths, outboard gear and desktop DAWs like GarageBand, ProTools and Live. Amos supports CoreMIDI (USB and WiFi), DSMI, and the Line6 MIDI Mobilizer.

Here's a video of Amos in action:

In Amos's physics-simulated room, collisions between objects trigger MIDI notes. Up to five duration discs (whole note, half note, quarter note, eighth note, sixteenth note) can be grabbed and thrown around the room. There are two 6-octave keyboards that can be configured via the Settings menu. When a disc strikes a keyboard key, it takes on that key‘s note value and emits that value for each collision until a new key is struck. Tilting the device controls the gravity in the room.

USB MIDI Requirements:
• iPad
• Apple iPad USB Camera Connection Kit
• Class-compliant USB MIDI interface

WiFi MIDI Requirements:
• A Mac, Linux, or Windows computer on the same WiFi network as your iPad
• Some kind of MIDI capable desktop app (Garage Band, Pro Tools, Logic, Live, Sonar, etc.)
