Downloads & Software Requirements:

Your Harmony H224 Professional Audio Interface has been designed to work with Mac OS operating systems, as well as Microsoft Windows operating systems.

Please note that your Harmony H224 hardware requires software downloads to work with all features designed for the product, and it is important to follow the directions below.

Note: The speed of your computer processor, amount of RAM, and capacity, size, and type + speed of your hard drives will greatly affect the overall performance of your recording system. A faster processor and more RAM can reduce signal latency (delay) and improve overall system performance.
The Windows OS installer also includes a Windows ASIO driver for great low-latency throughput performance. No driver installation is necessary for Mac OS.
