Latest update lets you turn your Focusrite Saffire PRO or Liquid Saffire 56 into a standalone device.

Focusrite's Saffire Mix Control, the powerful software mixer environment for the Saffire PRO range of audio interfaces, has been updated to allow compatible devices to run in Standalone mode, without the need for an accompanying computer.
The Standalone mode in Saffire Mix Control v1.7, which also runs alongside the Liquid Saffire 56 interface, works by recalling mixer routing settings stored inside memory on the interface itself. A computer is required for initial setup, but once you've programmed and saved your routing assignments to the hardware, you can use your interface as a free-standing summing mixer or a complex routing matrix, for sending signals around a stage or studio. You could even use it to get a Focusrite front end on your Pro Tools rig!
What's more, you can use the A-D and D-A converters in standalone mode to interface between analogue and digital audio systems, and use the headphone amp fed with its own dedicated monitor mix. Now your Saffire PRO or Liquid Saffire interface can be more versatile than you ever could have imagined!
The latest update of Saffire Mix Control also equips the Saffire Pro interfaces and the Liquid Saffire 56 with Dual Device Support. This means that two Saffire units can be used together at 44.1kHz or 48kHz, to form a seriously powerful audio recording and mixing system (see Dual-device Support device combinations table, below.)

If you already own a Liquid Saffire 56, for example, and want a few more ins and outs, there's no need to trade-in and lose your Liquid preamps, just get a Saffire PRO 24 and link it in with your current system! Similarly, if you have a Saffire PRO 40 and wish to have the innovative new Virtual Reference Monitoring (VRM) technology of the Saffire PRO 24 DSP in your rig, just install Saffire Mix Control v1.7 and run them simultaneously!
Also new in version 1.7 is a feature for Saffire PRO 24 DSP users, to allow them to send the VRM output to both headphone sockets simultaneously, or just to one. This will prove useful for engineers who want to demo their VRM mix to someone else, when the room isn't suitable or excess volume limits are an issue.
