| br>I'm sure I'm showing my ignorance here but I've been doing some simple demos for the omni filter.
I've always liked a number of the middle settings - ie when you get two lights coming up. I always thought that when you have both LP and BP or both BP and HP then you were simply in an intermediate state.
Doing some sweeps and then looking on a scope I'm seeing a notch appear - I know that when you put filters of different types in series or parallel you then create new types but I thought this was a simple cross fade. br> br>
