Hello, 
	I've got a question!
 
	I was about to buy a small interface box for two of my effects. but when I saw the price I thought that there was probably not much in it and that I could have everything I needed to tinker with one.  
	Someone has already opened one of these boxes?
 
	 
	I suspect they have just put an optocoupler and distribute the logic level on the Jack outputs? 
	And Empress call their one, midibox   
	Thank you  
	Bruno
