Pokemon Go Tips and Strategies

I have a simple task: To play a MIDI file I have using the Vienna Symphonic Library using its Demo Yamaha CFX grand piano, Bosendorfer, Steinway... So I downloaded their Demo samples, and it seems I need to run the "sampler" which is like a sound server... (is it Vienna Synchron Pianos)... or somehow let CakeWalk scan the VST and then use the plugin... This seems like a simple task but I just don't know how it can be done... Can someone tell me the steps to make it possible?
