It is a bit of a needle in a haystack I'm afraid. The General MIDI protocol doesn't actually specify
how something should actually sound, just the name of that sound. Each manufacturer would then have creative licence to make their Synth Pad 1, or indeed Grand Piano, Pipe Organ, Flute etc, sound as they see fit. The GM rules were just so a musician knows that if they bring up GM patch 1 they would get a piano, for example. So it could be that the audio clip that I found sounds nothing like what you've got on your keyboard.

Well, you can adapt any of the presets in Syntronik using the onscreen controllers, as well as layer upto 4 different instruments, but bear in mind that the instruments in Syntronik are not 'pure' recreations of their original inspirations like some other manufacturers VIs and so some parameters may not be available to you.
It might be that, if you favour the sound from your keyboard and you can't recreate with the VIs that you have, then just use the sound on the keyboard. Nothing to say you can't even with newer technology at your disposal.
