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.

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.

Procedure

Do one of the following:
- Select Studio > VST Instruments.
- Select the instrument track and open the top Inspector section.
Click Freeze.
In the Freeze Instrument Options dialog, make your changes.
Click OK.

Result

The instrument is rendered to an audio file, and on playback you hear the same sound as before freezing.
Less CPU load is used.
The Freeze button lights up.
The MIDI/instrument track controls are grayed out.
The MIDI parts are locked.

Note

To edit the tracks, parameters, or synth channels again, and to delete the rendered file, unfreeze the instrument by clicking Freeze again.
