Paul you are wrong:
The Korg i30 can import everything, as long as there is someone converting it!!

Lukitoh:
Very strange to hear you about the Korg i30 styles! The sounds could be much better indeed, but if you are going for the styles only you will be disappointed i think.
You can even buy the USB CD and you have ALL the styles of the other arrangers.

And who said you cannot save the VOLUME LEVEL of the different parts? Did you read the manual? In the Arranger Part: menu Mixer and then "write setting" .

Good luck!
