The fact that you can ' t delegate means that your name wont be as omnipotent as Hans ' not a personal dig sorry , just a very practical reason . Any musician working with Hans is I ' m sure happy to be working for a guy who will give them access to projects they would never have otherwise . It is not an unimaginable feat for a composer to have control over every instrument , but that composition would be boring uninspired to an extent . Hans gets the best musicians in the world on their chosen speciality instrument and lets them explore and be creative to give them and him inspiration . If you are a jack of all trades master of none producercomposer you won ' t be able to get that tone out of the oboe or get that interesting tone out of an eastern instrument .
