Maxuino + PWM and Uno not behaving as expected

I'm trying to control brightness of LEDs via pulse-width modulation. Only two of the out pins enabled for
PWM (5 and 9) work as they should, allowing me to dim LEDs. The others that should be able to be set to send PWM don't output anything at all when set to the analogOut mode (the indicator on the Arduino does not flash to indicate it is receiving a message).

Curiously, if I set the mode on the non-working PWM pins to digitalOut, they respond normally to messages in Max. Is it a problem with my Arduino unit or am I missing something?

Also, I tested simple LED fades on all pins in the Arduino IDE and it worked normally.

Let's see:

Seems to say that the Arduino is working fine, so the problem must be with the Maxuino code.
