1st 2nd ER Control about the very first early reflections is given with this parametersection: Changes timing and level of the early reflections behavior - use this to obtain a more focused or diffuse sound. It can change the overall sound as well ranging from a more 'colorful' to a rather 'transparent' sound. Changing the first affects the second and changing both affects other reverb details under the hood as well. This way altering the timing can affect the overall reverberation even if both 'LEVEL' controls are set to minimum (left most position). Timing is displayed in ms. Level control is unity in upper middle position and increases clock-wise (decreases counter clock-wise)
