The SanDisk Connect USB sticks act as a normal flash drive when plugged into a PC/Mac - or (one hopes) the USB drive socket on a PSR SX900.

Delivering much much more than that Yamaha wi-fi dongle.
Anyone here tried one out?
It seems the easiest way to me to share MIDI and style data between a computer and the arranger.
