VST instruments and instrument tracks
What do I need? Instrument channel or instrument track?
What do I need? Instrument channel or instrument track?
If you need a particular sound without knowing which VST instrument to use,
create an instrument track and use the preview features of the Presets browser to
find the sound you want.
Do likewise if the instrument track restrictions described above do not matter.
If you are planning to create an instrument track preset, complete with inserts and
EQ settings, you have to use an instrument track.
If you need to use multitimbral parts and/or multiple outputs, set up a VST
instrument channel.
Instrument Freeze
Like all plug-ins, VST instruments may 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 realtime (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 the
instrument 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, or the instrument track associated
with the VST instrument, are muted and locked (the controls for these tracks will
appear “grayed-out” in the track list and Inspector).
When you start playback, the rendered audio file is played back from an “invisible”
audio track, routed to the VST instrument’s MixConsole channel. Thus, any effects,
EQ, or mixing automation will still be applied.
You can also freeze the MixConsole channel of the VST instrument. This freezes
any pre-fader insert effects for the channels, just as when freezing audio tracks
(see
“Freezing (rendering) insert effects for a track” on page 234).
The result of the Freeze is that you get exactly the same sound as before, but the
computer processor does not have to calculate the sound of the VST instrument in
realtime.
Performing the freeze
The instrument freeze function is available in the VST Instruments window, the track
list, and the Inspector for instrument tracks.
1. Set up the project so that the VST instrument plays back the way you want it to.
This includes editing the MIDI tracks routed to the VST instrument, or editing the
instrument track, and making parameter settings for the VST instrument itself. If
you have automated parameter changes for the VST instrument, make sure that
the Read (R) button is activated.
2. Open the VST Instruments window from the Devices menu, or, if you are using an
instrument track, select the track and open the top Inspector tab.
