Instrument nomenclature is notoriously complicated and unreliable, depending on what source you reference. However the comparison of distinctions between bass recorder vs. great bass to cello vs. contrabass is specious and disingenuous. No composer in his right mind would ever substitute those strings for each other. Not to argue it endlessly, however. The recorder that was sampled is incredibly beautiful, in fact, I would rank it among the most beautiful of all VSL's sampled instruments, so I for one am glad they sampled that particular recorder.
Nevertheless I appreciate your making the distinction.
