Dear Khai, I have no need to read the operating instructions.

The functions you refer to are midi transfer functions requiring the relevant software and drivers on a pc. They have nothing to do with direct interfacing of flash memory (or floppy disk drive) usb devices plugged directly into the KN7000/2600. The KN7000/2600 does not have any host capability to enable communication with such slave devices.

I repeat that this will not work and you are merely giving people totally unfounded false hopes if trying to imply that it will.

Thus I rest the case.
