Changing the Linearity Display
Mode
The Timeline can be viewed in either a Linear
Tick (relative) scale or a Linear Sample (absolute)
Time Scale. MIDI and Instrument tracks, audio
tracks, and Tempo curves can appear and func-
tion very differently depending on the timebase
display settings.
The Linearity Display Mode pop-up menu deter-
mines whether the Tempo Editor displays
tempo events in an absolute (samples) timebase
or a relative (ticks) timebase.
Linear Sample Display The display of the Time-
line is sample-based and the location of tick-
based events (like Bars and Beats) shift after a
tempo curve is drawn. That is, as you change
tempo, the location of bars and beats move
against the fixed sample-based Timeline (such as
Minutes:Seconds). When working with sample-
based material, such as when you are tracking or
mixing, make sure that Linear Sample Display is
selected. This is especially true if you intend to
align the tempo and meter map to sample-based
events.
Linear Tick Display The display of tempo events
is tick-based and tempo event Bar|Beat locations
remain constant after the tempo curve is drawn
and all sample-based events move against bar
beat locations in the Timeline. When working
on any tick-based material, such as MIDI notes
or Elastic Audio events, make sure that Linear
Sample Display is selected. This is especially true
if you will be making tempo changes, but want
the bars and beats to remain fixed in the Time-
line.
To change the timebase display:
„ Click the Linearity Display Mode selector and
select a timebase from the pop-up menu.
Tempo Edit Density and Linearity Display Mode
When the Tempo Edit Density setting (in the
Tempo Editor) and the Linearity Display Mode
setting are both set to either a Bars|Beats Time
Scale or to an absolute Time Scale, Tempo edits
appear evenly spaced. When the Tempo Edit
Density setting and the Linearity Display Mode
setting are set so that one is set to an absolute
Time Scale and the other is set to a Bars|Beats
Time Scale, the number of Tempo edits appear
to increase or decrease over time (against abso-
lute time).
Linearity Display Mode selector and pop-up menu
Drawing tempo events using the Linear
Sample Display causes Bar|Beat based
material to move. This can make it difficult
to work on tick-based material. Digidesign
recommends that you use Linear Tick
Display when drawing tempo changes.
