If I understand what you're describing, Input Maps is the correct term. Please note that some of the input maps layouts do not completely correspond to the actual layout of the library mapping - some of the cymbals are in this category - so the SusCym E3 to G example you gave may very well be by design.
However, the TriggerTest file(s) should have everything lined up correctly to trigger in library-layout sequence (except for TenorLine stuff). And, when inputting, the note you're after should still be inserted with the correct notehead and location on staff. If that's not the case, send me the exact file(s) that exhibits this behavior. (Sent you a PM.)
