Does scratch live support MP3 Pro files?
Not sure if I'm doing something wrong...SSL reads the file info and loads it up but won't cue up or play.

afaik it doesn't. but don't bother with mp3pro anyway. mp3pro is only effective at low bitrates which you shouldn't be using. mp3pro is really only effective for web downloads/streaming.

I thought mp3 pro files were supposed to be backwards compatable (just without the advantages) but like spinthis says, they're only really for low bitrates.

yeh they - are backwards compatible...
