While I haven't used it myself, I've seen Frap Tools 321 advised to turn Pam's output into bipolar. You can shift the output by a DC value, so lowering it below zero, and if necessary add amplification up to 2x. I have a similar problem with Zadar, which generates positive-only values but can also be used as an LFO. I just take it into account that it's 0-10V instead of -5 - +5V.
