lukitoh,

I do not remember Korg I-30 has the capability of importing sounds from other keyboards since it does not have a sampler built-in. Perhaps you meant some sound sets that alter the preset sound setups of the I-30. A new Solton X1-HD costs the vicinity of US$3K and surely is too expensive to make a mistake at this price for most people. Have you been able to test a Solton X1 yet?
