I supose you use a driver (like pololu or easydriver) to control the steper.
You can use your soundcard and a small electronic circuit to get you computer control this hardware.

or you can also use another electronic device (like an arduino) that receive velocity command (that are not update at high speed) from pd and convert it to clock tick to control the steper driver.

cheers
