I've just spent a couple of hours trying to find a cable that will let me attach a flash drive, thumb nail drive (call them what you like),
but could I find one?!!!!
The problem is that the drive end of all the available cables is a male connection, and the connection on the flash drives, thumb nail drives etc. is ALSO a male connection. There are no flash drives available (as far as I'm aware) that can be plugged DIRECTLY into the back of the PSR-E423, you have to use a cable. Using a USB cable extension doesn't work because there are no extension cables available with the Yamaha type connection on one end and a FEMALE connection on the other end.
Long way around, I know,
but here's my question:
How do I connect a flash drive to the PSR-E423, giving me handy access to all these lovely styles and instruments out there?
