Sending analogWrite() to Arduino via Processing

I'm controlling 4 DC motors through Processing, using StandardFirmata on the Arduino.
When I test the motors with a simple sketch in Arduino, they work perfect. When I try to actuate the motors through Processing, they do nothing.
- I have checked the syntax of the Arduino library in Processing and I believe I have called the functions correctly.
- I have printed a list of serial ports to confirm that I am listening to the correct port.
- Both StandardFirmata and Processing are set to 9600 baud.
- If I change the analogWrite() to digitalWrite(pin,HIGH), I am able to turn the motors on.
Is there something I am missing when calling arduino.analogWrite() in Processing?
Help, please and thank you!
