My original Maschine Studio display is on the blink, horizontal line when in the mixing mode on channels 1-5, can't see my levels. I'm looking to buy a used Maschine Studio but have read that there are several issues with licensing. I have a Mk3 and Maschine+ but more comfortable with the Studio and would love to get another but no one has a new one for sale. Please advise. How can I get another license or can I use my existing License?
