Good afternoon, I love all the Factory demo songs on Yamaha Keyboards, and I would like to have on my PSR S970 the factory demo songs from other keyboards, like the PSR S700, S900, S910, etc. I had searched on Yamaha MusicSoft and also on other pages, but I hadn't found the midi version of that demos songs. Can anybody please tell me where I can buy those PSR S factory demo songs in midi format so I can play them on the PSR S970. Thanks!
