What this thing looks like it might be the quite famous Sonic Implants soundfonts bundled into a soundfont player, arranged by GM & GS patch assignments. I read some of the reviews of the individual instruments (I went right to the acoustic piano page) and the reviewer talked about downloading the piano sound from their Sonic Implants page.

Sonic Implants soundfonts always were quite good. They would give one away now and then back 5-6 years ago.

I would be very surprised if it is not multi-timbral - which I think you might mean that it responds to multiple MIDI channels, assigned to different instrument patches.

If it isn't, then it's really not that great of a deal. Not enough info on the product page to tell yes or no.
