However, do not get too tied down with these preset
descriptions because they are not sacrosanct - they are
merely guidelines and the SPEECH 2B preset may do a
fantastic job on a piece of classical music!
A list of the presets are given later.
Sometimes, our presets may not quite satisfy your needs
and some kind of 'manual override' is required. This is the
ADJ(ust) control.
As mentioned, behind the timestretch presets are a lot of
controls. The ADJ parameter gives access to the key
parameters in any one preset and allows you to make
adjustments to the preset with one, easy to use control.
There are no strict rules to using this control other than, if
the selected preset gives you almost acceptable results but
there are few glitches in the processed sound, try tweaking
the ADJ control and do it again.
This sets the timestretch amount. The range is 50% (half
the length of the original) to 200% (twice the length of the
original).
You can select whether the timestretch will be referenced
to the IN point you have marked or the OUT point you
have marked. For example:
IN OUT
ORIGINAL
STRETCH = 150%
LOCK TO IN
With LOCK TO IN selected, the end of the cue to be
processed will be later in time.
With LOCK TO OUT selected, the start of the cue being
processed will be earlier in time.
This function has just two options - SOURCE IN and
SOURCE OUT. These can be selected by moving the
cursor to the field specifically and using the +/- DATA keys
but it may be more conveniently selected simply by
pressing F1 - LOCK? - and using this as a toggle switch
between the two selections.
This allows you to select whether the timestretch process
will slip all subsequent cues on the track or not. There are
times when you may want all cues after the stretch (in the
case of LOCK TO SOURCE OUT) to move accordingly to
accommodate the new cue's length in which case, select
SLIP WHOLE TRACK.
There may be times, however, when all cues before and
after the stretched cue must remain locked.
