Digital Performer 5.11 is now shipping. If you own Version 5.0, 5.01 or 5.1, you can download the free Version 5.11 updater
here. This maintenance release includes numerous program enhancements and optimizations. The 5.11 update also includes hundreds of new presets for DP5's six included virtual instrument plug-ins.
If you have Kontakt v1.x (Kontakt.component) in your /Library/Audio/Plug-Ins/Components folder... take it out. Move it somewhere else, out of the Components folder...
Otherwise, DP 5.11 hangs/stops/dies on startup.
Anyways,
Kontakt 2.2 is out (now a Universal Binary) so no need to keep v1.x
One thing I noticed is DP 5.11 startup and loading of instruments seems faster to me.
