In the sense of modern DAWs/VSTs, sure, but in the sense of the synthesizer as a standalone instrument, its absolutely not designed to reproduce the sound of other instruments. Its an electronic device that outputs specified parameters. Whether that happens to coincide with parameters set by other artists/instrumentalists to 'reproduce' other tonal profiles, that's a byproduct, not a feature.
