Advanced EXS24 mkII RAM Management

32-bit applications can only address approximately 4 GB of RAM. The EXS24 mkII can address its own memory space in the 32-bit version of MainStage. This enables the EXS24 mkII to use any available RAM in the system— outside the memory used by the application and operating system. You must have at least 5 GB of RAM installed in your computer to use this feature.

The 64-bit version of MainStage has virtually no RAM restriction, and automatically addresses all available memory in the system. This enables the use of huge sampler instruments.

To set advanced memory options for the EXS24 mkII in 32-bit mode
  1. Choose Options > Virtual Memory in the EXS24 mkII Parameter window.

  2. In the Virtual Memory window, select the checkbox labeled Active.
