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.


  1. Select the instrument track and open the top Inspector section.
  2. Click Freeze.
  3. In the Freeze Instrument Options dialog, make your changes.
  4. Click OK.


  • 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.


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