what does it mean when it says "low quality" in the js description? it doesn't really sound "low quality"
second, currently when learned, the cutoff increments in 100hz. how can i lower that value to something to prevent zippers?
third, when using this as a sweeping effect, would i be better off using something else?
thanks.
