Hi Nedim.

If I were to apply your logic to your own products and customers it would go like this.

1: Customer buys your sample library.
2: Customer has a problem with the library and contacts you for support.
3: You tell the customer to contact KORG and don't offer them any support just because KORG advertised the keyboard as having a sampler.

That's pretty much what your saying here mate.

Regards
James.
