I am not sure if I am doing a good job of explaining the problem
No, I'm afraid you are not.
the OSC data coming in ranges from 0 - 1 this is in turn converted into 0-200 steps for the motors to move
So, how would you know that more than one rotation is required? That would require a value higher than 1.
or if there was a way to send information in such a way that the motor can loop on itself.
Not sure what this means. Of course a stepper motor can rotate more than 360 degrees. It is up to you to keep track of where it is, and to tell it how many steps to get to the new position that you want it at. It simply hears, from the motor controller, "step", "step", "step".
