I found the following information on the Mackie DL website, "Did you purchase a DL1608 on or after September 12, 2019? Get your free AvidŽ software here." The link takes you to a AVID page where you can create an account. And it asks for the serial number of your DL mixer. I haven't had time to try it. But I didn't find anything on the Mackie website for those of us that bought our DL before September 12, 2019.
