Every time you want to use a freeze-enabled plug-in choose the plug-in with the (z)
suffix from the VST menu. An additional line, called Freeze Header, will be seen on
opening any Freeze-enabled plug-in, which among its usual settings has 2 flake like
keys. When the flakes are white, nothing is frozen, everything works as usually.
Flashing flakes indicate a plug-in is being frozen. Blue icon shows the presence of
a frozen plug-in. Small flake icon at the left side refers to regular freeze function,
while large icon at the right side indicates Ultra Freeze.
To copy settings from a regular (not Freeze-enabled) plug-in to an Freeze-enabled
one first save your settings to .fxp/.fxb files then load the files from "File" menu
of freeze-header of your freeze enabled plug.
Stop your song at the position where you want freeze to stop.
Now the flake icon turned blue, indicating that the data has been captured and
saved, and status bar now shows the beginning and end positions of the frozen part
of your plug-in.
Now every time your song is played back as soon as it reaches the frozen part,
the plug-in editor will be grayed out, indicating that any plug-in parameter tweaking
is useless in this area of your song, as FX Freeze bypasses the plug-in and streams
the data it has previously saved while freezing the plug-in, releasing the CPU resources
previously consumed by the plug-in. Please note, that you can use your plug-in as
usually in stop mode or with not yet frozen parts of the plug-in, though you may turn
this option off by unchecking the corresponding checkbox in the Options dialog.
If you work with a multi-channel VST instrument and wish to freeze not all, but
only the most processor hungry MIDI parts, use Selective MIDI Channels freezing. Select
your MIDI channels in Options dialog and do the rest of the procedure in the normal way.
To free up not only CPU, but also RAM consumed by the plug-in and its libraries (which
is especially important with modern multi-gig libraries) use the Ultra-Freeze function.
The procedure is the same as described above with 2 exceptions:
- Click the large flake icon at the right side of the freeze header.
- After your data is frozen, the plug-in and its libraries will be unloaded from the
machine and the plug-in editor will close.
Of course, with Ultra-Freeze you lose the option of using the plug-in in stop mode
or with unfrozen parts of the plug-in, same is true about selective MIDI channels,
cause there's no instrument to play your unfrozen MIDI channels since the plug-in
is now unloaded. However you now don't have to worry about our frozen plug-ins as
everything is now streaming from Freeze data directly to your host application
without consuming CPU and RAM resources.
You can freely switch between Freeze and Ultra-Freeze modes without any risk of
losing your data. Simply unfreeze your plug-in by clicking on the blue flake icon.
Should you ever wish to unfreeze your plug-in, simply click on the blue flake
icon, it will turn white, your plug-in will be unfrozen and all freeze data will be
deleted. Now everything works just the way it used to be previously to freezing the
plug-in with an option to freeze or ultra-freeze your data if needed.
During the installation of FXF, 3 special plug-ins, called Track Freeze Mono,
Track Freeze Stereo and Track Freeze 5.1 are placed into your VST folder. These
plug-ins can be used as both inserts and sends for freezing of audio streams. This
is especially useful while working with plug-ins incompatible with FXF, such as
Logic native synths or DPS-card plug-ins.
To use Track Freeze insert the Track Freeze plug-in to the next insert slot after
the plug-in(s) you want to freeze and complete the freeze procedure (see
description above). Now disable the frozen plug-in to free up CPU resource.
In order to more precisely automate freezing of VST instruments you can use
special MIDI control change events. Place CC 80 event with value greater than 64
in the MIDI track right before the portion to freeze (the CC number can be
changed in the FXF Options dialog window). Place the same CC event with value
less than 64 in the end of the portion. Now the portion will be frozen exactly
between the 2 controller change events. For even greater precision you can create
track objects with these events and insert them from track view window.
Since most of the host applications perform the bounce faster than in real-time,
all disk streaming plug-ins (including FXF) must be aware when the host is in bounce
mode, so they can buffer some data to keep up with the host. A special opcode has
been developed in VST standard to inform the plug-ins about the host mode.
Unfortunately, not all host applications have it working properly. Cubase and
Nuendo fully support this feature, while Logic, SONAR and some others don't.
We have incorporated a special Bounce button for those of you who work in the
hosts that don't support this feature. Press the Bounce button in any of the
FXF windows before bouncing and don't forget to turn the function off when you're
finished. Never leave it active during normal playback.
Depending on the host application, both Mute and Solo of the frozen tracks may
or may not work properly. A special Mute and Solo buttons have been provided in
the FXF window to mute/solo frozen tracks in case they can't be muted/soloed from
the host. Please note, that FXF Solo mode cannot mute tracks in the host, so it
only mutes all currently frozen tracks except for soloed one.
To corect the relative time position of the frozen track you can use the
Offset parameter in the FXF Options dialog window. This is especially useful
when working with hosts that do not support PDC.
FX Freeze can safely store your frozen data on your HD and then load it when the
song is loaded. One thing we want to mention though: when working with hosts fully
supporting VST 2, such as Cubase, Nuendo, you simply save your song, and a special
folder named song name>_Frozen containing all frozen data (named
plug-in name.random number.raw) will be saved along with the song.
With the other host applications, like Logic, the data will be saved in the folder
set by pressing "Set as Default" key in the Options dialog. If you wish to save the
data in your song folder, you have to make one extra step, i.e. specify your song
folder: when you are ready to freeze all the plug-ins (you have Freeze-enabled all
the necessary plug-ins), click the "Browse" key and specify your song folder, then
click "Set for all running" key. All the plug-ins will save their freeze data to the
One more thing to remember: should you wish to completely remove a plug-in from
your song, be sure to unfreeze the data by pressing the blue flake icon, otherwise
you'll have to clean up your freeze data manually.
