It is a toy-piano sample format soundfount. It installs without trouble (a. Exe that generates a. Sf2), it weighs heavy, can be read with the free sfz sampler
Note that there are only two octaves used ... but it matches well with the philosophy of the thing (you ever seen a toy-piano has 88 keys???)

The sound is nickel ... slightly wrong in the "low" if it can be said for such a piano, ca really gives the little brother of the piano score ...

Well it is on that you can not ask for anything more for a toy-piano ... ca makes clear.
Now it's a bit on that one instrument gadget, but it's free so why not?
