CS filters cannot self-oscillate; they are wired with external
feedback limiting on the resonance control VCAs inside the IG00156s.
You might be hearing chorus unit clock noise. Or a noisy FET somewhere
leaking a VCO signal. My CS80s are noisy in this regard, probably due to
age more than anything. --Crow

I´ve noticed this playing presets like brass with all the brilliance up. Do you guys have the same effect or there is something wrong with my CS80?
