1: Will it integrate with other DAWs. Yes of course, but not as deeply as with Cubase. You must think of the n Series as an Analog appoach. No motorized faders, no scene memories. It's really an "organic" approach to the computer. We find it most refreshing. Yet, with Cubase you can use these "work modes" that REALLY speed up the workflow. Since Cubase AI come with it free, you can easily track into Cubase and then transfer the wave files to any DAW for mixing. All the connections, routing, transport, monitoring connection is already set up so it's a no-brainer to use it.
In terms of the Control stuff for other DAWs start,stop, FF, REWind and Rec are all implemented. Here is a link to the manual download page for more detail.
2: Can you add more faders?
In the future, you will be able to connect up mutiple n series to have more mix-down channels or more tracking preamps , etc. Since the faders are not controllers, it would be better to use a USB control surface.
The audio signal path is SO QUIET that motorized faders would ruin the pristine specs of these units
n Series Manual
hope this helps.
In the future, we will discuss this new paradigm Hardware Integration, Vs Hardware Automation. Both are useful and serve as different tools. That's why we make the O series and the n Series. It's easy to remember the difference if you think Aut-O-mation and iN-tigration
the n is awesome when you interact with the computer and the O is great when you do many repeatative tasks such as live sound and facility projects. Many believe Home studios and small project studios tend to be more intimate and lend themselves to a more Organic approach.
