airplay

Hello guys. I'm returning to using iReal after a couple of years of being away from music, and have noticed that there is no longer the option to offset the song audio so that the player position indicator syncs up with the music when using AirPlay and other streaming protocols. This feature...

Either of my airplay speakers will work with iRealpro from the iPad, but not from Mac OSX. (However, my Mac plays both airplay speakers just fine from iTunes.) I've got the latest version on both. Anyone got any ideas?

I have a gig tomorrow where I am using my irealb to play from. The unfortunate thing is that the point where I plug into the house speakers is about 30 feet away. I am considering buying the belkin Bluetooth receiver, so I don't have to run a 50 foot headphone cable through a retail store...
