Pro Tools | DigiLink I/O License

Pro Tools DigiLink IO License

Use your existing audio interfaces with Pro Tools | Ultimate

Get a new Pro Tools | HDX or HD Native system to use with your current non-Avid interface, which features the same high I/O channel count capabilities offered by our Pro Tools | HD Series interfaces using any third-party DigiLink-enabled audio interface with the Pro Tools | DigiLink I/O License.

With this license, you can work with up to 192 audio I/O channels with a three-card Pro Tools | HDX system (64 I/O channels per card), or up to 64 I/O channels with Pro Tools | HD Native. This license effectively doubles the maximum I/O for all non-Avid interfaces in your system, compared with using Core Audio or ASIO.

If you were an existing customer that was on an active Upgrade and Support plan for Pro Tools | HD on 9/28/16, we’ve got great news! We deposited a DigiLink I/O License at no charge in your Avid Account for you to download and use. All Pro Tools | HD Series interfaces now also come with this license—no need to purchase separately if mixing Avid and non-Avid interfaces together. And if you don’t have an active upgrade plan, we’re also including the license with all Pro Tools | Ultimate Upgrade Reinstatement Plan purchases.
