Thanks for the reply, It isn’t so bad in filter matrix mode, I guess I should say the rate is around 1 or 2 o’clock. Outside of filter matrix mode. It happens when it is automatically sweeping through the flanger, and it’s depth is set higher than 3 o’clock.

I have found if I simply put another effect after it, it helps alot. It was at the end of my effects chain. I put a Memory Boy behind it and it isn’t so bad, (i’m thinking doing that is limiting the output of the SEM) I still have to keep the flanger depth below 3 or 4 o’clock to keep the signal clean. Lately, i’ve just been using it with the flanger depth set to 12 o’clock or even less.
