But it's often hard to find a host application that does everything you want, and even harder to figure out the complexity of routing audio and MIDI between your extra systems. A common approach is to use an application specifically designed for hosting plug‑ins on your additional machines, since running a fully featured sequencer brings to mind sledgehammers and nuts. And while the answer of adding another computer to your rig may seem obvious, it is often anything but simple. One of the biggest problems when working with software instruments, in my experience, is that one computer is never enough. Ensemble Pro opens up VSL's hosting technology to third‑party instruments and allows 32‑bit and 64‑bit Mac and Windows systems to communicate over a network, spreading the software instrument load.
