Hi Bruno,
It is not much money and for what you pay you get a lot. If I ever figure out how to setup a gig play list I'll take it out on a gig. I like to have everything organized and flow from song to song on gigs. I have all my Tyros 4 stuff setup that way - just need to learn now to do it on my little Korg. I have found some really good styles to match up with tunes I play but I don't know how to rename them and save them either on the SD card or on free spots on the keyboard. I have also found stuff I'll never use and would like to get rid of that so the setup would be personalized for my needs.
So far I am a happy camper.
Deane
