Detecting the Tempo of an Audio File
To edit a step envelope, proceed as follows:
1. Select the step envelope type you want to edit, and move the mouse over the
waveform display.
The mouse pointer turns into a Draw tool.
2. Click a step and drag the mouse up or down to edit the value.
• To create a step envelope, that is, modify consecutive steps, keep the mouse
button pressed and draw a curve.
Randomizing Step Envelope Values
If you select a step envelope type and click the Randomize button, Sequel sets the
selected step envelope to random values. With this function you can quickly give an
audio loop a completely new sound.
Resetting a Step Envelope
You can reset all values of the selected step envelope by clicking the Reset button.
Detecting the Tempo of an Audio File
The Sample Editor gives access to the tempo detection function. Tempo detection
allows you to detect the tempo of an audio file and align it to the bars and beats grid
of the project. For example, it can be applied to complete CD or MP3 tracks with a
single constant tempo that you want to use for one of the following:
• Creating a loop
Once you have detected the tempo of an audio file, you can create a loop by
setting up a cycle encompassing the section that you want to isolate. You can then
cut the loop, and drag it to the MediaBay with the tempo information included. For
information about setting up a cycle and about cutting, see
“Cycle Playback” on
page 24 and “Splitting” on page 29.
• Creating performance parts
You can create performance parts from the imported track and use the pads on
the Performance Page to remix your track in realtime, perfectly aligned to the
project tempo. For information about performance parts and the pads, see
“Live
Pads and Chain Play Mode” on page 49.
• Creating mixtapes
You can create mixtapes from your music library where all tracks follow the project
tempo. You can easily create soft tempo transitions between the tracks. If needed,
you can add tempo changes to your project by adding a tempo track.
