AST audiovisual study tool

[chillout]

Because I have a silver membership I have tried the 2 demos with the AST .I am using my ipad device and when the music starts playing I don't see the sheetmusic highlighted has to where in the music is currently being played and when the video goes off the first page the next page is not visible .I am not impressed with it ,if it worked how it should I would consider upgrading to gold membership.

Does anybody else use this feature and if so how do you find it.
