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.
If the Processing Overload indicator in the Audio Performance window lights up or you get
crackling sounds, you have the following options:
Activate Freeze Instrument Channel.
This renders the instrument into an audio le and unloads it.
Activate Suspend VST 3 plug-in processing when no audio signals are received for VST 3
instruments.
This ensures that your instruments do not consume CPU power on silent passages.

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
1. Do one of the following:
Select Studio> VST Instruments.
Select the instrument track and open the top Inspector section.
2. Click Freeze Instrument Channel.
3. In the Freeze Channel Options dialog, make your changes.
4. Click OK.
RESULT
The output of the instrument is rendered to an audio le, and on playback you hear the
same sound as before freezing.
Less CPU load is used.
The Freeze Instrument Channel button lights up.
The track controls are grayed out.
The MIDI parts are locked.
You can still adjust the level and panning, make EQ settings, and adjust the effect sends.
NOTE
The audio le is saved in the Freeze folder that can be found in the following location:
Windows: within the Project folder
macOS: User/Documents
AFTER COMPLETING THIS TASK
To unfreeze a frozen track, click Freeze again.
