People who haven\'t looked through an orchestration book won\'t be able to get it to sound amazing without some study, because it responds more like a real orchestra than the big libraries. Basically, if you don\'t do mod wheel, legato, etc. it will just do default flat envelopes like a real orchestra would. This idea puts the responsibility of expression in the hands of the composer, which is a must if you are going to compose for real orchestra some day. Different fixed samples of crescendos, etc. will not be malleable enough to play every piece. With GPO, you don\'t have to compose around the samples.
