### [1] STEREO WIDTH SEPARATION
- Adjust Stereo Width separation of the two audio input channels. The current state will be displayed on top of touchdisplay (0° : 90°)

### [2] Ambisonic order
- lets you set the spatial resolution of your sound scene.

### [3] DISPLAY
- This full-color multi-touch display shows information relevant to A³Motion’s current operation. Touch the display (and use the hardware controls) to control the A3Motion interface. See Operating Instrucions to learn how to use some basic functions

### [4] Speed Encoder
- Use these encoder to adjust length of trackpattern (bars)

### [5] MOTION SAMPLE PADS
- Each channel has a column of four iluminated sample pads. See Operaton to use basic functions

### [6] Record Button
+ Hold the Rec-Button and one of the 4 pads (per channel) to start record. Record runs from next Beat for one Bar setup by Speed Encoder. 

### [7] Tempo Tap Button
* Current Tempo is indicated by top indicator on the Display

### [8] Set One Button
* Set Tempo Clock Counter to first beat

## Operating Instructions
- Set looplength with Function Encoder [4]
