I have just upgraded to Logic Pro 9.1 and MainStage 2.1. When I look in the applications folder and select Logic Pro or Mainstage and get info, I don't see a check box for 32Bit. I have a 2GHZ /2GB MacBook Pro. How can I tell which mode I'm in? What am I missing?

Jamie & Rounik, Thanks for your reply's. I checked that Logic Pro and Mainstage is the latest versions 9.1 and 2.1 respectively. Still, the only check box on the "get info" pages is "locked" and that's grayed out with no check mark. I am not sure how I would boot SL in 64 Bit mode. Where would I look to know if I was in 64 bit mode? Puzzled!

Rounik, Bingo !! that's the problem. I need to upgrade my computer to run in 64 bit mode. Thanks for your help. Jr

Hi, I am fairly new to Logic Pro, I am using sounds from a Roland GR1 guitar synth. Two instruments for GR1 has been setup in the environment and I can select the sounds 0 to 127. I have a second instrument setup for the rest of the sounds. How should I set the boxes at the top of the instrument list to select as the 2nd bank.
