Requirements
The following equipment is required for VST System Link operation:
Two or more computers.
These can be of the same type or use different operating systems - it doesn't matter. For example, you can link an Intel-based PC to an Apple Macintosh without problems.
Each computer must have audio hardware with specific ASIO drivers, installed and working.
The audio hardware must have digital inputs and outputs.
Of course, to be able to connect the computers the digital connections must be compatible (i.e. the same digital formats and connection types must be available).
At least one digital audio cable for each computer in the network.
A VST System Link host application installed on each computer.
As of this writing, VST System Link is implemented for Cubase SX, Nuendo 1.6 and Cubase 5.1 (System Link version). Any VST System Link applications can connect to each other.
Additionally, we recommend that you use a KVM switchbox:
Using a KVM switchbox
If you want to set up a multi-computer network, or even a small network in a limited space, it's a good idea to invest in a KVM (Keyboard, Video, Mouse) switchbox. With one of these switchers you can use the same keyboard, monitor, and mouse to control each computer in the system, and switch between computers very rapidly. KVM switchers are not too expensive, and very easy to setup and operate. It you decide not to go this route, the network will function just the same, but you may end up doing a lot of jumping from one machine to the other while setting up!
