I use mostly Styles and I've spent a ton of time editing and continue to re-edit as I use them. I also edit the few SMF's I use. I just spent a lot of time reorganizing my main songlist and found I use about 60 Styles which cover anything I need. I edit a Style for live play and it may be used for one or a dozen differnt songs. I've also paired down the sounds I use both in the Styles and for my RH/LH sounds. Less is better for live play.

BTW -BACKUP BACKUP BACKUP, did a gig Thursday and when I tried my main USB drive at home it was unreadable !! First time this happened.
BUT- I make copies to at least 3 other USB drives, copy to my and a copy to my backup HD.
