On my unit, the Stereo Spread knob only works in 1 mode. There are supposed to be 2 modes (accessed via settings) Centered (default) and Gradual. When I try to choose these modes it does not change the behaviour of the knob. The knob will always work in Centered mode. However, the mode does work correctly when using it in the mod matrix, for example, if I assign voices to voice pan.
So is this a bug on everyone's PolyBrute? Please can someone test on their unit and say if it is the same for them?
