Bei gearslutz (noch zu 9.1) näher erläutert:
"
Next-gen Pre-gen™ engine — DP's Next-generation Pre-gen engine transparently pre-renders audio output from virtual
Instruments and plug-ins to dramatically reduce their CPU load. In version 9.1, this feature has been highly optimized for greatly enhanced CPU performance.
DP seamlessly manages transitions between pregenerated audio and live audio as needed (such as when you record a virtual instrument live). In addition, virtual
Instruments are always available for preview activities, such as editing notes in the MIDI Graphic Editor or using a VI’s on-screen keyboard (previously they were only active when playback was underway). To fine-tune the responsiveness of plug-ins and virtual
Instruments, go to Setup menu > Configure Audio System > Configure Studio Settings and adjust the Prime Milliseconds setting.
MOTU has worked hard to ensure a high level of compatibility with third party virtual
Instruments and effects. There may be cases where pre-generation may not work as expected with a given 3rd-party plug-in. These cases should be reported to MOTU and the plug-in vendor so that compatibility can be fully established. In the meantime, you can run the plug-in or instrument in real time.
If you would like a plug-in or virtual instrument to run in real time only while its window is open (to improve level meter timing in the plug-in window for example), go to the minimenu and choose "Run Open Instances of This Plug-in in Real Time". Close the window to return to Pre-gen mode (or uncheck the menu item). This setting applies globally to all instances of that plug-in and is saved globally.
To force a virtual instrument track into real-time operation all the time (not just when its window is open), record-enable any MIDI track that targets the instrument. To force an audio track's effects into real time, the track can either be record-enabled or monitorenabled. Alternately, the effect can be placed on an aux track, either in a chunk or a
VRack, with bussing used to access the effect. Aux track effects are always rendered in real-time."
EIne Art freezen im Hintergrund, aber bei VSTis immer noch die Möglichkeit Midi-Daten zu editieren!
Interessantes feature, Frage ist, wie gut es mit vielen 3rd PArty Plugins wirklich funktioniert (siehe Text oben)
