A³ Motion

A³ Motion numbered

[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

The A³ Motion display in operation

The screen has three bands. Along the top sits the status bar: the current tempo on the left, the beat grid in the middle — it fills as the bar runs — and the clock source on the right.

The middle band is the room seen from above. Each channel is a coloured blob; drag one and its sound moves with it. The four dark shapes at the corners are the speakers, lit by what they are actually playing, and the field around the sphere shows where the energy in the room is coming from.

The bottom band holds the settings of the selected clip, framed in that channel’s colour: its shape, how it is mapped in elevation, how it moves in time — speed, direction, what happens at the end, and the fade that closes the loop — and its filter. The narrow strip on the right is global rather than per-channel and carries the recording mode.

[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]

  • Press and hold down one pad [5] to record motion from touchscreen

    • The pad will flash green / red to indicate record mode

    • Tap on the screen and hold to grab channel soundsource

    • Release the pad and move the soundsource on touchscreen until record length is reached. Longer motion will overwrite previously recorded data

    • Release the touchscreen to end record

    • The pad will stay green to indicate play mode

  • Pads without stored motion are dark

  • Pads with stored motion are white

  • Press white buttons to switch motion on the next beat (related to 120bpm)

  • Width [2] and Reverb [3] will not be recorded
