Conclusions
Vienna Ensemble Pro may not appeal to hobbyists or keyboard players whose studio projects stick to pop and rock instrumentation,
but for composers who frequently run demanding sessions,VEP is an absolute god send.
While computer technology may advance to the point where we'll never need more than a single machine, we're not there yet.
There's need for this kind of product,and since VEP is the best in its class, it wins our key Buy award.
