Windows 7 Verifying Yamaha USB MIDI Driver Installation and Connectivity https://www.yamahamusicsoft.com/help

To download/transfer files to computer, you need 2 softwares from yamaha website. USB MIDI drivers and MUSICSOFT DOWNLOADER.
Install drivers first,and then Musicsoft Downloader.
Connect keyboard to PC/notebook by USB cable.
Run Musicsoft Downloader.
If you click "Electronic Musical Instrument" in the Musicsoft Downloader display.and then "System Drive", a file named "08PG76BUP" will appear in the lower right corner of the Musicsoft Downloader display. This is the backup file that will transfer to computer.
Usually yamaha came with CD-ROM that contain divers and softwares + user manual,so you don't need to download.
I hope this helps.

Thats all. In Ableton,the setting MIDI input must be set to USB MIDI.

It doesn't use a USB to MIDI adapter (such as the UX-16.) It has an onboard MIDI controller and uses a standard USB A-B cable. You just need to install the driver from the CD-ROM or here, and plug it in. You can get the manual from the same page or here. Setup is on page 99.

The BUP files are yamaha's proprietary back up file format.
Having the appropriate drivers installed, once you make the usb connection from computer to keyboard (yamaha), you should now be able to navigate the Yamaha's files as if it were a drive on your computer. I recommend placing the file in a directory with similar files.
Make a backup beforehand to avoid and problems.

You can connect it with USB connection to your computer. It should be plug and play, but some drivers might be required.
You can connect it also via MIDI interface: - you will need sound-card with MIDI input connector, or you can use special MIDI device like M-Audio UNO.

You need to have a basic recording program installed on your computer. If you use Apple you can use garageband. If you use Windows you can install audacity http://sourceforge.net/projects/audacity/
You will have to install the drivers of our yamaha keyboard than connect it with the usb cable to your computer and select the PSR S710 as an input in your recording program.
