Problem
The version number of Pitch 'n Time LE displayed in Logic is always 1.0.0 despite a newer version of Pitch 'n Time LE being installed.
This is now only relevant for Pitch 'n Time LE version 1.2, and is fixed in version 2.0
Workaround
You can confirm which version of Pitch 'n Time LE is actually installed by getting info on the Pitch 'n Time LE.component file which can be found in the Macintosh HD > Library > Audio > Plug-Ins > Components folder.
