Linking a dc speed controll and pulse generator

Hi guys, I have a square wave pulse generator that puts out 12v peak to peak. I also have a dc pwm motor speed controll. What I want to do is modulate the square wave from the signal generator by using the dc motor speed controll. Any ideas on how to connect the 2 so that I can get a modulated output?

How does the controller get feedback from the motor?

Hack the circuit that gets feedback from the motor to modulate the output of the motor controller.
