I recently purchased an used moxf8 keyboard after hearing how awesome it is. Afterwards found out about the free premium collection sample package. I purchased an 512M expansion board, registered with yamaha.com, saw the package advertised for free but, it is unable to add it to cart. Is this sample collection still available? Is this option outdated? Tried to call customer service and stayed on hold for 45 minutes with no response. I will try again later but has anyone tried to make this happen recently.
