−The type of effect is encoded in the second byte of the out-port write, with specific settings for the effect in the further bytes.
+The type of effect is encoded in the second byte of the out-port write, with specific settings for the effect in the further bytes. The upper nibble of the effect is OR'ed with 0x80 before it is transmitted, it doesn't appear that it makes any difference in the effect

; Auto/Anti Center (Complex) : This is similar to a spring force, but force is constant towards/away from angle points. Multiple of these can be stacked in different slots to emulate a spring and any angle.
