That little program seems like an oscilloscope.
What the computing is doing is basically the computer that most Critical and Eikon have inside. Control the voltage and give you a reading (in numbers rather than waveform).
I could be wrong.
I Agree with Centri, if preset cannot be recorded (like you can do with an Eikon or critical) the computer become more of a burden than help unless the machine has a chip that can record the parameters sent.
It would be good to have this guy pop in and share some info as we could be guessing all year long
