I've created a device to control three buttons via MIDI notes. The notes can be in any octave 0 - 9. C triggers the Time button. E triggers the Echo button. And, F triggers the Fast button. By adding a MIDI track to a cutting project and inserting C, E and F notes you can automate the entire cutting procedure using my device. I incorporated relays so the device is 100% electrically disconnected from the lathe. Using transistors would have required me to share a ground which I did not want to do.
Here are some pictures. I will be installing the device into my pitch box tonight. Video of it in use will follow soon.
I will be offering these units for sale on my site http://www.deepgroovesmastering.com
