Instrument Freeze
3. Click the Freeze button for the VST instrument (the button to the left of the VST
instrument slot), or the Freeze button in the Inspector for the instrument track.
The Freeze Instrument Options dialog opens with the following options for the Freeze
operation:
Select “Freeze Instrument Only” if you do not want to freeze any insert effects for
the VST instrument channels.
Use this if you are using insert effects on the VST instrument channel(s) and want
to be able to edit, replace, or remove these after freezing the VST instrument.
Select “Freeze Instrument and Channels” if you want to freeze all pre-fader insert
effects for the VST instrument channels.
If your VST instrument channels are set up with the desired insert effects and you
do not need to edit these, select this option.
You can set a Tail Size time to let sounds complete their normal release cycle.
Otherwise, the sound might be cut off at the very end of the freeze file.
When you activate “Unload Instrument when Frozen”, the frozen VST instrument
will be removed.
This is useful if you are freezing an instrument that uses a lot of RAM, e. g. for pre-
loading samples. By unloading the instrument, the RAM becomes available for
other plug-ins, etc.
4. Click OK.
A progress dialog is shown while the program renders the VST instrument audio to
a file on your hard disk.
The Freeze button lights up. If you check the Project window at this point, you will find
that the relevant MIDI/instrument tracks have grayed out controls in the track list and
Inspector. Furthermore, the MIDI parts are locked and cannot be moved.
5. Play back the project.
You will hear exactly the same sound as before freezing the VST instrument – but
the CPU load will be considerably less!
If you selected “Freeze Instrument and Channels”, any insert effects used by the
VST instrument are also frozen (except for the post-fader inserts). However, you
can always adjust level, pan, sends, and EQ for frozen VST instruments.
The Freeze button in the
VST Instruments window…
…and in the Inspector.
