Does anyone know if there is a way to adjust an instrument or effect parameter relatively? For example, if I have a patch already dialed in on a software instrument, I would like to make small adjustments by moving a knob on my controller left and right from the center position. Or for example, using the X-Y controller in the environment, if the control is the centered, then I have my patch as I have set it, but if I move the control off-center, the patch changes relatively. This way if I move it back to center, it goes back to the original patch.
