9.5 Parameter Types
The best way to understand the effect of parameters is to turn on the HUD, watch the corresponding
parameter change as you turn an encoder wheel, and see the effect on the output.

range -180° to +179.995°. One bit is 0.0055°. 32768 is 0.0°. Positive rotation is clockwise.
9.5.2
Audio Pan

centre, and 255 full right. 128 is the default.
