Hi , I have the same issue . If i try to modulate the frequency parameter of a preset , whatever source i choose ( lfo ext-1 , etc…) , the ecliple gets unhappy and crackle , and overload . for example in preset 341 fliter echos , if i assing the frequency to be modulated , it does that crackle . On most fiter type presets if i try to modulate the frequency this problem occur .
