Gerard Carroll Hi Gerry,
Are you asking how to transfer custom styles to your keyboard in general? Or about this specific new direct transfer method that is described in this topic?
There are 2 options - a traditional way of transferring styles using an usb stick, and an experimental method of transferring styles directly via an usb cable.
If you are not tech savvy I would just stick to the traditional method. For this you need to download a style file to your laptop as you normally would, then copy it into an usb stick, then insert it into your keyboard. Inside the keyboard go to the style selection screen and switch to the USB disk, you will find your style there that you can load right from an usb stick. If you want to keep it in your keyboard's memory permanently so you can play it not only when an usb stick is inserted you can copy it from an usb disk into "User" section using keyboard's copy button.
Hopefully that helps.
