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 CPU overload indicator in the VST Performance window lights up or you get crackling sounds, you have the following options:
Activate Freeze for instruments.
This renders the instrument into an audio file 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.
