Thanks Dr Fred. I have never messed with the raduino. Changing a sketch scares me. I do need to learn more about how to read the file/sketch save the file and modify the file.
Maybe I didn't explain my simple method very well. Part 1. A 25-50 ohm resistors in series with each outer potentiometer tab to green and another resistor in series to yellow. That would prevent the fast frequency change from engaging (I assume), since the center/violet would never "see" a direct (low or 0 ohms resistance) connection to either yellow or green raduino point. Part 2. A momentary push button switch from the center/purple pot tab to the raduino yellow wire and another to the raduino green wire. This would replicate the full turn, 0 ohms, of the pot CW or CCW. No ground to any of these connections (on purpose anyway) Simple? Work? I hope so. Part 3. A 3 turn or 10 turn pot? We'll see, stay tuned.
