The Lexicon Lambda is a good interface which provides both midi and audio connections to the computer via USB. However, if you already have the Peavey PV 14 mixer, this will give you the audio connection and a cheaper midi interface such as the Roland UM-ONE (available from pg music) is all you need to get going.

Once your up and running with RB, you should be able to select the MX200 in the same way as you do for software VST plugins.

If you need any more help, give us some details of how you want to use your set-up and some specifications for your computer and operating system.
