Channel Pan configuration is available via the Channel Control Tile to the right of the Main Screen.
Press the Pan button beneath and to the right of the Channel Control Tile Screen:
The 'Selected' channel is shown at the top of the screen; the Prev and Next arrow buttons either side of it can be used to scroll channels.
The graph in the Screen represents the pannable area, with the blue square indicating where the audio is placed in space. Drag the square around the graph to pan the signal around the space.
Pinch the graph area to adjust the width of the signal (not applicable to mono channels). The arrows at the edge of the blue area will be coloured red if the width has been inverted (L-R swap) or green if not inverted.
All relevant pan parameters can also be controlled using the encoders down the left side of the screen; the encoders are assigned to the functions in the screen area nearest to them.
Parameters which are not relevant will be greyed out.
To re-centre the pan, press & hold Reset Pan (top right of the screen, or the encoder next to it.)
