THE BEATKEEPER™ III
The AXIS 9 includes the latest Numark patented Beatkeeper™ technology. The
Beatkeeper™ automatically tracks beats based upon a combination of
frequencies and rhythm patterns in the music. It shows BPM in the display and
outputs 4-count (a.k.a. measure) information about the music in a marching
bar graph.
The Bar Graph: Most dance music and rock is set up in 4 beat
increments called measures. Many of the features within the
AXIS-8 use this information for incredible results. It’s important
to understand the basics of how the Beatkeeper works to
effectively take advantage of other advanced features in the unit.
The bottom LED is for the 1 st beat or “Down Beat”. Typically,
most music starts on the downbeat so the unit sets the first beat
to where the music begins. Occasionally this may not be correct or
you may wish to reset it. To reset the downbeat simply tap the
“BPM” button at the new downbeat location as the music is
playing or while in pause.
BPM: This button is used for resetting the downbeat and also re-
calibrating the BPM. The Beatkeeper is considered by many to be
the most accurate automatic beat counter on the market today,
however, it occasionally may have trouble determining the correct
BPM. This can happen when the music contains complex rhythms,
or if it starts without a beat at all. If you know the BPM showing
in the display is incorrect, or if the beat LEDs are not flashing with
the beat, you have 2 options to reset the Beatkeeper.
1. Tap “BPM” on the downbeat and hold for a second. This will
tell the unit to search and display the next BPM it finds.
2. If holding the “BPM” button doesn’t work you can manually
tap “BPM” on the beat and the display will indicate the new
BPM. The BPM will be based upon the average of your last 8
taps. The Beatkeeper will then know which beats in the
music it should be using to determine the correct BPM and it
will track them through the song.
Occasionally the unit will be tracking the wrong beat but have the
correct BPM. To reset the downbeat, simply tap the “BPM”
button once on the downbeat.
