Hi Two basic choices:
1) Convert them both to logic levels and use a gate. 2) Use a relay. Both would need some sort of timer to drive them. Both would disrupt the instrument when the switch took place. I know of no "cheap / easy" ways to take care of the switching glitch. There are fancy / expensive ways.
