a VSTi that has a soundbank similar to cheesy modern casio/yamaha learner keyboards?

[idrinkalot]

A friend of mine got a Yamaha E403 off Craigslist recently and the thing is an absolute blast to play with! You know.. tons of shot-in-the-dark presets like "trumpet" and "marimbas" and "ambulance"? I've got a few specific VIs, but nothing that has anywhere near the range of sound these things have. I don't really want to get one of the actual keyboards because I feel like it would be a waste with all their tutorials and built in speakers, and I already have enough keyboards laying around.

Are there any all-in-one style instruments that simulates keyboards like this? I see these things sort of like guitar amp sims.. great for fooling around with to get inspired while songwriting. I'm not looking for anything "pro".
