Working with the Tempo track
7. Click at that position in the event display and drag the
position to the downbeat of the second bar in the record-
ing.
When you click, the pointer will snap to the ruler grid.
You do not have to match the downbeats (“ones”) – in this figure, beat
“2” in the second bar is matched to the “two” in the recording’s second
bar (simply because the snare drum hits on the upbeats are easier to
spot in the waveform image).
When you dragged the grid you changed the tempo value
in the tempo event at the first downbeat. If the drummer
held a fairly consistent tempo, the following bars should
now match pretty well too.
8. Check the following bars and locate the first position
where the audio drifts from the tempo.
Now, if you simply adjusted that beat in the tempo grid to
match the beat in the recording, the tempo event at the
first downbeat would be changed – this would ruin the
match in the previous bars! We need to lock these by in-
serting a new tempo event.
9. Locate the last beat that is in sync.
This would be the beat just before the position where the audio and
tempo drift apart.
10. Press [Shift] and click at that position to insert a tempo
event there.
This locks this matched position. The material to the left will not be af-
fected when you make adjustments further along.
11. Now match the tempo grid to the next (unmatched)
beat by clicking and dragging with the Time Warp tool.
The tempo event you inserted in step 10 will be adjusted.
12. Work your way through the recording this way – when
you find that the recording drifts from the tempo, repeat
steps 9 to 11 above.
Now the Tempo track follows the recording and you can
add sequenced material, rearrange the recording etc.
Matching to hitpoints
If you have calculated hitpoints for the audio event you are
editing, these will be shown when the Time Warp tool is
selected.
• The number of hitpoints shown depends on the Hitpoint Sen-
sitivity slider setting you’ve made in Hitpoint mode.
• If you activate the Snap to Zero Crossing button on the tool-
bar, the Time Warp tool will snap to hitpoints when you drag
the tempo grid.
• You can use the Create Markers from Hitpoints function (on
the Hitpoints submenu of the Audio menu) to create markers
at the hitpoint positions. This can be useful when using the
Time Warp tool in the Project window, as the tool will be mag-
netic to markers (if Snap to Events is activated on the toolbar).
Using the Time Warp tool in a MIDI editor
This is very similar to using the tool in an audio editor:
• When you use the Time Warp tool, a tempo event is automat-
ically inserted at the beginning of the edited part – this tempo
event will be adjusted when you warp the tempo grid with the
tool. Material before the edited part won’t be affected.
• Only the default mode for the Time Warp tool is available. So
when you use the tool, the edited MIDI track is temporarily
switched to linear time base.
• The rulers in the MIDI editors can be set to “Time Linear” or
“Bars+Beats Linear” mode (see “The ruler” on page 340) –
the Time Warp tool requires Time Linear mode. If necessary,
the ruler mode will be switched when you select the Time
Warp tool.
• If Snap is activated on the toolbar in the MIDI editor, the tool
will snap to the start and end of MIDI notes when you drag the
tempo grid.
Typically, you would use the Time Warp tool in a MIDI
editor to match the Cubase tempo to freely recorded MIDI
material (much like the audio example above).
