VST Instruments
VST instruments are software synthesizers or other sound sources that are contained within Cubase. They are played internally via MIDI. You can add effects or EQ to VST instruments.
Playing Back VST Instruments
After you have added a VST instrument and selected a sound, you can play back the VST instrument using the instrument or MIDI track in your project.
VST Instruments and Processor Load
VST instruments can consume a lot of CPU power. The more instruments you add, the more likely you will run out of processor power during playback.
Freezing Instruments
If you are using a moderately powerful computer or a large number of VST instruments, your computer may not be able to play back all instruments in real time. At this point, you can freeze instruments.
Freeze Instrument Options Dialog
The Freeze Instrument Options dialog opens when you click Freeze. It allows you to specify exactly what should happen if you freeze an instrument.

The following controls can be found in the Freeze Instrument Options dialog:

Freeze Instrument Only: Activate this option if you still want to be able to edit insert effects on the synth channel after freezing the instrument.
Freeze Instrument and Channels: Activate this option if you do not need to edit the insert effects on your synth channels.
Note
You can still adjust level, pan, sends, and EQ.
Tail Size: Allows you to set a tail size time to let sounds complete their normal release cycle.
Unload Instrument when Frozen: Activate this option to unload the instrument after freezing. This makes the RAM available again.
