After our thorough scientific analysis (read, “Playing with Logic for a couple of hours”), we believe that it is safe to update to v9.1. We do have a few recommendations that we have outlined below.

We recommend that Snow Leopard users continue to run Logic in 32-bit mode until more plug-ins update to 64-bit. Even though you can run plug-ins in 32-bit mode, we experienced more crashes than should be expected on a pro setup. In our testing the benefits of the additional memory available in 64-bit mode did not outweigh the cons of the crashes. When running in 32-bit mode, Logic seems to load more quickly and doesn’t appear to be any less stable than 9.0.2 in our testing.

We will be monitoring the popular Logic discussion venues and stay on top of the issues that other users find with the update. In the mean time, we will definitely be utilizing the support for longer file names to keep our files organized. If you have any suggestions for users who haven’t upgraded yet, leave them in the comments.
