Working with the Tempo track
While you are dragging, the track(s) you are editing are
temporarily switched to linear time base. This means that
the contents of the tracks remain at the same time posi-
tions regardless of the tempo (there is an exception to this
in the Project window, see below).
4. When you release the mouse button, the musical posi-
tion you clicked on matches the time position you dragged
it to.
This is because the Time Warp tool changed the last tempo event on the
Tempo track (and/or added new ones, depending on window and us-
age), thereby scaling the tempo track to fit.
Rules
• When you use the Time Warp tool, the tempo value of
the last tempo event (before the click position) is adjusted.
• If later tempo events exist, a new tempo event will be
created at the click position. This way, the later tempo
event(s) will not be moved.
• If you press [Shift] and use the Time Warp tool, a new
tempo event is created at the click position.
[Shift] is the default modifier for this – you can adjust this in the Prefer-
ences (Editing–Tool Modifiers page).
• If you use the Time Warp tool in an editor, a tempo
event will be created at the start of the edited part or
event. Only the currently edited track will be affected – but
note that events to the right of the edited events or parts
(on the edited track) will be affected as well.
• If you have made a selection range (in the Project win-
dow, Audio Part Editor or Sample Editor) and use the
Time Warp tool within that range, the tempo changes will
be confined to that range.
This means tempo events will be inserted at the start and end of the se-
lection range, if needed – useful if you need to adjust the tempo within a
certain area but want all material outside that range to stay in place.
• When you click with the Time Warp tool, it snaps to the
tempo grid in the window.
• When you drag the tempo grid to a new position, it can
be magnetic to events in the window.
In the Project window, this requires that Snap is activated and “Events”
is selected on the Snap pop-up menu – the grid will then snap to the
start and end of events or parts, and to markers. In the Sample Editor,
this requires that Snap to Zero Crossings is activated – the grid will then
snap to hitpoints (if any). In the MIDI editors, this requires that Snap is
activated – the grid will then snap to the start and end of notes.
• The function will create tempo values up to 300 bpm.
Viewing and adjusting tempo events
When you select the Time Warp tool, the ruler of the ac-
tive window is shown in brown. Existing tempo events are
shown in the ruler as “flags” with the tempo values dis-
played.
This helps you see what’s going on, but you can also use
this for editing the tempo track:
• If you press the create/erase modifier key (by default
[Shift]) and click on a tempo event in the ruler, it is deleted.
• You can click on a tempo event in the ruler and drag to
move it.
This automatically edits the tempo value in the event so that elements to
the right keep their positions.
• If you press [Alt]/[Option] and move (or delete) a tempo
event in the ruler, the tempo value is not adjusted – this
means elements to the right will be moved.
This is the default modifier key for this – you can adjust this in the Prefer-
ences (Editing–Tool Modifiers page).
Using the Time Warp tool in the Project
window
In the Project window, there are two modes for the Time
Warp tool:
• In the default mode, all tracks are temporarily switched to lin-
ear time base when you use the tool. This means that all tracks
will keep their absolute time positions when you adjust the
tempo track.
• In the “musical events follow” mode, no tracks are switched to
linear time base. This means that all tracks that are not set to
linear time base will follow the changes you make to the tempo
track.
You select the Time Warp mode by selecting the tool,
clicking on the tool icon and selecting from the pop-up
menu that appears.
