Using Tempo Detection
1. Drag the audio file that you want to analyze from the MediaBay or the Windows
Explorer or the Mac OS Finder into the Arrange Zone.
2. Double-click the audio event to open it in the Sample Editor.
3. In the Sample Editor, click “Tempo Detection” to open the Tempo Detection
section.
4. Click the “Detect Tempo” button.
The following happens:
- Sequel analyzes the audio event and defines a single constant tempo for the whole
audio event.
- The project tempo is set to the detected tempo.
- A reference beat inside the audio event is detected. In the Arrange Zone, the
reference beat is displayed as a thin vertical line in the audio event.
- In the Arrange Zone, the audio event is moved to align the detected reference beat
with the project grid.
5. Play back the audio event with the metronome click turned on to find out if the
analysis directly led to a perfect result.
If this is not the case, you can make corrections with the buttons now enabled
below the Detect Tempo button.
Correcting the Detected Tempo
Sometimes, the detected tempo may be half or double the tempo that it should be.
• Use the “Half Tempo” or “Double Tempo” button to set the project tempo to half or
double the detected tempo.
The audio file is moved again to match the metronome click.
It may also be the case that the first downbeat is not detected correctly and has an
offset to the correct musical downbeat.
• Use the arrow buttons (“Nudge Left” and “Nudge Right”) to move the audio file in
steps of eighth notes to manually align the first musical downbeat of your audio file
with the first downbeat of the metronome click.
Smart Transpose
When you set the project root key in the Pilot Zone, it becomes the reference that any
audio file or MIDI loop follow. When you add a file with a defined key to your project,
it adapts to the project root key.
Smart Transpose makes sure that the loop is transposed to the nearest interval or
pitch. This way, no loop is transposed by more than six semitones. Therefore, loops
never sound too unnatural because the pitch was raised too high or too low.
Let’s see this in action:
1. Load the project “Smart Transpose” found in the “Sequel Tutorial 5” folder.
2. Open the MediaBay.
!
Only close the Sample Editor or deselect the audio event if you are sure that the
tempo is correct. The tempo detection settings cannot be adjusted any more after
deselecting the events or closing the editor.
!
If you use the “Half Tempo” or “Double Tempo” button, all manual offset corrections
that you made previously are discarded.
