CREATE (EXTRACT) GROOVE
The Create Groove command lets you create your
own Grooves from MIDI note data in any track, or
beats within soundbites that have been beat-
analyzed by Digital Performer’s Beat Detection
Engine. The source material can come from any
Digital Performer file, any standard MIDI file or
any beat-analyzed audio file or loop. Grooves can
be any length.
Extracting grooves from audio
Audio data must be beat-analyzed before you can
create a groove from it. For details, see “Extracting
a groove from audio” on page 670. After audio has
beats, the procedures below can be used to create
grooves from the audio.
Creating a groove
To create a groove:
1 Select the MIDI or audio data you wish to use as
source material for the groove.
You may select them in the Track List, the Track
Overview, or any of Digital Performer’s editing
windows. The groove will start at the beginning of
the first measure of your selection, and its length
will be a whole number of measures.
☛ When you choose MIDI data for a groove, the
data must be aligned with Digital Performer’s
metronome (main counter). For example, you can’t
use a rubato passage, unless you first use the
Record Beats feature to align Digital Performer’s
measure and beat boundaries with the music. For
audio data, however, the groove can be extracted
from any audio file that has been beat- and tempo-
analyzed, even if it does not currently match
Digital Performer’s main time ruler.
2 Choose Create Groove from the Region menu.
The Create Groove window appears.

3 Open a groove file in which to save the groove,
or create a new groove file with the New File
button.
4 Type in a name for the groove.
5 If desired, change the meter for the groove.
This setting affects the overall length of the groove,
and it also affects how many beats are in each
measure. Try to choose a meter that most closely
resembles the beat structure of the groove you are
creating.
6 Choose a default beat division for the groove
from the menu.
See “Choosing a beat division” below regarding
this option.
7 Click OK to save the groove.
The new groove gets added at the bottom of the
groove list.
Choosing a beat division
The choice you make for a beat division when
creating a groove is an important one, for it
governs the underlying resolution of the
quantization that occurs when you apply the
