It's not you, it's the sample library. Samples have a ground noise which is typically inaudible when only playing one sample at a time, but when you play hundreds of samples simultaniously that ground noise becomes indeed audible as the noise adds up with each sample. So it's a matter of the signal to noise ratio (SNR) of the original audio hardware being used for the recordings. Today's audio interfaces have a much better SNR than decades ago, that's why you would not hear the noise with more recent sample libraries, at least with like ~100 voices.
