BEATKEEPER OPERATION
Channel Selection
When your mixer is first turned on the channels selected
will be 1 & 2 respectively. If you wish to track the beat of
another channel, tap on the channel select button until the
desired input is reached.
NOTE: The Beatkeeper will track the source that is
selected with the channel toggle switch.
Syncing Your Beatkeeper
When learning how to use the Beatkeeper, choose
some dance music with a hard, steady beat.
Start the music for left channel of your
B e a t k e e p e r . When the Beatkeeper has located the
beat, the BPM display will illuminate with the music's Beats
Per Minute.
You'll notice a flashing green LED every time the
Beatkeeper detects a rhythm defining instrument. The
Beatkeeper will soon flash a red LED on every beat, the
same way you would tap your foot to the beat of the music.
The Beatkeeper will display a BPM which will update every
five-seconds while scanning. As long as the beat is well-
defined the BPM number will equal the beats per minute of
the song being played. Once you see the red beat
LED flashing with the beat of the music, press
the respective Sync Lock button, and the Sync
Lock LED will illuminate.
Activating the Sync Lock tells the Beatkeeper to stop
scanning the music for a different BPM and to start tracking
the beat changes of the current BPM as you adjust the
pitch of the music. This function is manual to ensure that
the Beatkeeper is right on the beat. Once the Sync
Lock LED is on, the Beatkeeper tracks the
beats of the music and updates the BPM display
on every beat.
To unlock, simply tap the Sync Lock button once and
the Beatkeeper is back in BPM scanning mode.
After syncing an audio input, try speeding up and slowing
down the music. You'll notice that the red beat LED will
continue to flash on the downbeat, and the BPM number
will adjust itself to match the tempo of the music. This
indicates that the Beatkeeper is successfully tracking the
beat and will continue to do so throughout your mix. If you
stop the music you will notice the Beat LED will go solid and
the BPM number will remain in memory. Once the music is
restarted the Beatkeeper will remember the last tracked
rhythm pattern and pick up on the beat right away.
P L A Y the music, O B S E R V E the beat match, and
PRESS the Sync Lock Button. That's it. If you can do
that twice, you can mix with the Beatkeeper.
Beat Assist
The Beatkeeper is foolproof. The Beatkeeper can track
any music up to 199 beats per minute. The unit, however,
is set to automatically track tempos between 80-150BPM.
Of course not all music is within this range, you may need to
track the high tempos of Meringue or Salsa, or the low
tempos of R&B slow jams or Reggae. Let's face it, not all
music has hard steady beats either and sometimes you just
need the music set up yesterday For these occasions we
have the Beat Assist Button.
If the Beatkeeper is having trouble matching
the beat to the flashing red Beat LED, or if you
need to sync up Immediately, tap the Beat Assist
button 2-8 times as you hear the beat, the same
way you would tap your feet to the music.
Pressing the Beat Assist Button more than once aligns the
Beatkeeper to your taps. Notice that the Sync Lock LED
automatically illuminates, signifying that the Beatkeeper is
now locked in with the beat. Simply put, if the Beatkeeper
isn't on track, or you're in a real hurry, you need to press a
button twice instead of once.
If the Beatkeeper is synced to the correct BPM
but is aligned to the music's offbeat, tap the
Beat Assist button with the beat of the music
just once and you will have brought the Beatkeeper back
in sync.
