Apple has recently launched MainStage 2.1.3, an update to MainStage 2, which is part of the paid upgrade to Logic Studio (2009).

In addition to posting a short technical note about the new MainStage release, Apple has posted an extensive set of release notes on the Support area of its website, detailing not only the changes occurring in version 2.1.3, but also why it is necessary to use it under a relatively new version of Snow Leopard.

Apple specifically notes that users running MainStage 2 on a computer with an i5 or i7 CPU should seriously consider updating to Mac OS X v10.6.5 or later. The reason?

“Mac OS X v10.6.5 contains several kernel level enhancements that improve MainStage performance on these computers,” according to the Cupertino tech giant.

However, Apple makes no mentioning on whether the update adds the least bit of support for Lion, the next major version of Mac OS X coming out next month.

With that out of the way, Cupertino then lays out all the changes made in MainStage 2.1.3, detailing the various code corrections applied to areas like MIDI Processing, Compatibility, Stability and, of course, General tweaks and enhancements.

For example, one important change is that the value displayed in the Layer Display Height Inspector control now properly updates itself after Undo or Redo.

Avid users of the live performance application will undoubtedly appreciate a fix for a MainStage 2.1 bug that set the send values on certain channel strips incorrectly when patches were imported.

Undo now works correctly after a channel strip is cut from a patch and pasted at the Set level, and mapping multiple Pedalboard Sync parameters to a single screen control now works properly, Apple says.

The update actually improves the overall performance of the application, making it a must have for Logic Studio users.
