Apple’s release Logic Pro 9.1
Logic Pro is now a 64-bit application which well now create better music for songwriters and producers. The older application the 32-bit applications have a memory limit of 4GB. However a 64-bit application’s memory usage is virtually unlimited.
The plug-ins that you may use will be supported by this application. Using the 64-bit there is one downside which may take longer “One problem plug-in makers face is with the Pace Anti-Piracy technology. Currently, Pace requires plug-ins to be 32-bit, so some plug-ins may take longer than others before making the move to 64-bit”
Apple has been proactive in allowing users to take advantage of Logic Pro 64-bit while still using 32-bit plug-ins. With the release of Logic Pro 9.1, Apple included Audio Unit 32-bit Bridge, a seamless way for 32-bit plug-ins to be recognized while running the application in 64-bit mode.
