Question: has anyone used the Yamaha 9000 Pro in a recording studio environment yet ? Specifically, have you tried routing individual sounds/voices to the sub-outputs and recording them ? How quiet are the outputs ? The reason I ask is because I own a Roland EM-2000, which is fine for stage use but I noticed that in the studio the outputs have quite a bit of noise to them that other keyboards with similar sound engines (such as the Roland SK-88) do not. I am thinking of upgrading to the 9000 Pro and would like to know if it's a good studio keyboard. Comments ?
