I got to Nibelheim and played the FFVII song on piano (I knew where it stopped too coz I saw the Magemasher video) but nothing. And Tifa was in the party. But she doesn't have Meteor Strike yet, do I have to get that for her first?
Btw, I haven't forgotten how to get Vincent. Last few playthroughs I had him against Hojo (though only in the case of the last did I give him a Headband to stay awake) and I will do so again this time. The only thing I needed to check of course is the combination of the safe. I know Hojo has some hints and stuff but the mansion has enemies that use Confuse. (shudder)
Also, what is the system for unlocking new Limit Breaks? Usually it only happens in some battles where character's Limit meter is full, as if it's "get up here this many times". But I think Tifa got Dolphin Blow in a fight where she never got a full Limit meter. Also, Meteodrive, I'm not sure I got that before as I always thought Dolphin Blow came right after Waterkick and I don't remember Tifa ever doing that attack in previous playthroughs. Unless I just kept missing Meteodrive's slot.
It is worth noting that I have been letting her Limit meter get more full this playthrough to try to unlock her Limit Breaks faster.
