The actual instrument of this track is no longer addressed by MIDI files of this track
and can even be deactivated, provided that it is not used by other MIDI tracks.
Select “Track unfreeze” (Ctrl + Shift + U) to change the original MIDI data at a later
point in time that was "frozen”. The track is now returned to the state in which it was
"frozen", but again requires the initial CPU power for processing the instrument.
Alternatively, you can use the feature “Edit track freeze”. In this case, a new single-
track VIP is opened with the original track. This track cannot be played together with
your arrangement. As soon as you save this project, a new freeze object is processed
and included in the original project.
Freeze also works with single outputs in different tracks than the main output track
(instrument outputs 1+2). You can also freeze these tracks if they do not contain
MIDI information and do not hold objects. The MIDI data that has been routed to the
track or to the individual output of the instrument automatically creates an audio file
that is now played instead of the original instrument. In order to prevent double
playback of the data, deactivate the single output of the instrument manually in the
frozen track.
To edit freeze data you cannot only use the "Track freeze edit" function, since there is
no MIDI data available on this track that could be edited. Therefore, “unfreeze” the
track and edit the MIDI data of the send track. You can then refreeze the track.
Note: As long as the instrument is not entirely unloaded from the track it remains
loaded into the RAM memory of the system. Samplers or instruments that require
considerable amounts of memory also require this when their insert tracks have been
frozen.
Tips on handling virtual instruments
• You can realize so-called stack sounds (i.e. sounds that use several synthesizers
and play these in unison) by opening several instruments and activating
monitoring for all channels.
• To program beats, you can create and save individual drum maps in the MIDI
editor that match the respective instruments.
• If an instrument can limit the amount of voices, then you can use this option to
save CPU power if you do not require the full number of voices.
• Some instruments use sound sets according to the "General MIDI" standard. You
can use these instruments for playing back MIDI files according to the GM
standard. Please import the entire MIDI file to a single track including all
channels. Make sure that virtual instruments can also receive program change
commands that are also saved in such a file, so that the correct sounds are
played back.
