Logic Pro 9 32 Bit? 64 ? Options

[zam]

Hello ,
I ve just installed the upgrade from logic pro 8 to logic pro 9 , and in the same time i ve upgraded my OSX to snow leopard .
I thought that now logic will be in 32 bit , but when i load sample in 32 bit , nothing ??
When i go in the preference / audio and try to set the resolution ( i ve live ableton and the 32 bit work fine) , only 24 bit can be activated .
My question is , it is normal to have this system set like this , on my screen when i start the soft , it display logic pro 9.0.1 ( 32 bit) , so the soft start in 32 bit , how can be sure that the soft is in 32 bit , and if i want to increase to 64 bit , what is the operation to do.
Thanks a lot , in advance for your answer
