Ok, hier gaat hij dan. Dit zijn de 3 bladzijden uit de Cubase Manual over Freezen en Unfreezen.
Heb het geexporteerd als TXT uit de PDF manual die ik hier op de PC heb staan op het werk...

The Instrument Freeze function
Like all plug-ins, VST Instruments can sometimes require a lot of processor
power. If you are using a moderately powerful computer or if
you are using a large number of VST Instruments, you may come to a
point where your computer cannot handle all VST Instruments playing
back in real time (the CPU overload indicator in the VST Performance
window lights up, you get crackling sounds, etc.).
Enter the Instrument Freeze function! This is how it works:
• When you freeze a VST Instrument, the program renders an audio file of its
output (taking into account all unmuted MIDI parts routed to that VST Instrument).
This file is placed in the “Freeze” folder within the Project folder.
• All MIDI tracks routed to the VST Instrument are muted and locked (the controls
for these tracks will appear “greyed-out” in the Project window and Inspector,
and the parameters for the VST instrument).
• When you play back, the rendered audio file is played back from an “invisible”
audio track, routed to the VST Instrument’s mixer channel. Thus, any effects,
EQ or mixing automation will still be applied.
The result of all this is that you get exactly the same sound as before,
but the computer processor doesn’t have to calculate the sound of
the VST Instrument in real time.
• If you need to edit the MIDI parts routed to the VST Instrument or adjust the settings
on the instrument itself, you need to unfreeze the instrument first. This removes
the rendered file and restores the MIDI tracks and VST Instrument. Once
you have made the necessary adjustments you can freeze the instrument again.

Performing the Freeze
1. Set up the Project so that the VST Instrument plays back the way you
want it.
This includes editing the MIDI parts routed to the VST Instrument and making parameter
settings for the VST Instrument itself. If you have automated parameter changes for
the VST instrument, make sure the Read (R) button is activated.
2. Open the Project Setup dialog and make sure the Length setting
matches the actual project length.
The rendered freeze file will span the whole project length. Altough empty (silent) sections
will not affect the size of the freeze file, the Instrument Freeze operation will take
longer if you have an unnecessarily high Length setting.
3. Open the VST Instruments window from the Devices menu.
4. Click the Freeze button for the VST Instrument (the button to the left
of the VST Instrument slot).
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 and the power, bypass and edit buttons
for the VST Instrument are greyed out (and the control panel closes if
it was open). If you check the Project window at this point you will find
that the relevant MIDI tracks have greyed out controls in the Track list
and Inspector. Furthermore, the MIDI parts are locked and cannot be
moved.
5. Try playing back the project.
You will hear exactly the same sound as before Freezing the VST Instrument – but the
CPU load will be considerably less! You can make settings for the VST Instrument
channel in the Mixer as usual – add EQ, effects, make level adjustments, etc.

Unfreezing
If you need to make adjustments (either to the MIDI tracks or to the
VST instrument parameters) you need to unfreeze the VST Instrument:
1. Click the Freeze button for the VST Instrument slot again.
You will be asked whether you really want to unfreeze the instrument.
2. Click “Unfreeze”.
The MIDI tracks and VST Instrument are restored and the rendered “freeze file” is deleted.
